  1. Uranium resources production and demand: a forty years evaluation 'Red book retrospective'

    International Nuclear Information System (INIS)

    Uranium Resources, Production and Demand, also familiarly known as the ''Red Book'' is a biennial publication produced jointly by the NEA and the IAEA under the auspices of the joint NEA/IAEA Uranium Group. The first edition was published in 1965. The red book retrospective was undertaken to collect, analyse and publish all of the key information collected in the 20 editions of the Red Book published between 1965 and 2004. The red book gives a full historical profile of the world uranium industry in the areas of exploration, resources, reactor-related requirements, inventories and price. It provides in depth information relating to the histories of the major uranium producing countries. Thus for the first time a comprehensive look at annual and cumulative production and demand of uranium since the inception of the atomic age is possible. Expert analysis provide fresh insights into important aspects of the industry including the cost of discovery, resources to production ratios and the time to reach production after discovery.

  2. Uranium supply/demand projections to 2030 in the OECD/NEA-IAEA ''Red Book''. Nuclear growth projections, global uranium exploration, uranium resources, uranium production and production capacity

    International Nuclear Information System (INIS)

    World demand for electricity is expected to continue to grow rapidly over the next several decades to meet the needs of an increasing population and economic growth. The recognition by many governments that nuclear power can produce competitively priced, base load electricity that is essentially free of greenhouse gas emissions, combined with the role that nuclear can play in enhancing security of energy supplies, has increased the prospects for growth in nuclear generating capacity. Since the mid-1960s, with the co-operation of their member countries and states, the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA) have jointly prepared periodic updates (currently every 2 years) on world uranium resources, production and demand. These updates have been published by the OECD/NEA in what is commonly known as the ''Red Book''. The 2007 edition replaces the 2005 edition and reflects information current as of 1st January 2007. Uranium 2007: Resources, Production and Demand presents, in addition to updated resource figures, the results of a recent review of world uranium market fundamentals and provides a statistical profile of the world uranium industry. It contains official data provided by 40 countries (and one Country Report prepared by the IAEA Secretariat) on uranium exploration, resources, production and reactor-related requirements. Projections of nuclear generating capacity and reactor-related uranium requirements to 2030 as well as a discussion of long-term uranium supply and demand issues are also presented. (orig.)

    World demand for electricity is expected to continue to grow rapidly over the next several decades to meet the needs of an increasing population and economic growth. The recognition by many governments that nuclear power can produce competitively priced, base load electricity that is essentially free of greenhouse gas emissions, combined with the role that nuclear can play in enhancing security of energy supplies, has increased the prospects for growth in nuclear generating capacity. Since the mid-1960s, with the co-operation of their member countries and states, the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA) have jointly prepared periodic updates (currently every 2 years) on world uranium resources, production and demand.

  5. Uranium resources and uranium supply

    International Nuclear Information System (INIS)

    The availability of natural uranium is currently considered unproblematic. Out of concern about the sufficient availability of uranium, an international working group of OECD-NEA, in which the Federal Office for Geosciences and Resources (BGR) participates as a German partner, has conducted analyses of uranium availability since 1965. Its findings are published biannually in the so-called 'Red Book', 'Uranium, Resources, Production, and Demand'. Changes in the political situation worldwide have profoundly influenced the military importance of uranium and thus also greatly improved its accessibility. As a consequence, there was a decline in production in the nineties from approx. 57,000 t of U in 1989 to, at present (2001), approx. 35,000 t annually. Estimates of the worldwide requirement of natural uranium in 2015 range between approx. 55,000 t and 80,000 t of U, because of the unforeseeable extent of the use of nuclear power, as against approx. 63,000 t of U in 2001. The most recent statistics published in the 1999 Red Bock show low-cost reserves (up to Dollar 40 per kg of U) of 1325 million t, and 2234 t of uranium at extraction costs of up to t Dollar 80 per kg. This indicates a statistical range of reserves of approx. 35 years. It should be noted that these figures are snapshots of a dynamic system. A resumption of extensive exploration and technical developments could greatly influence the resource situation. In the nineties, for instance, there is a net increase in uranium reserves of approx. 700,000 t of U as a consequence of exploration activities. (orig.)

  7. Uranium. Resources, production and demand

    International Nuclear Information System (INIS)

    The events characterising the world uranium market in the last several years illustrate the persistent uncertainly faced by uranium producers and consumers worldwide. With world nuclear capacity expanding and uranium production satisfying only about 60 per cent of demand, uranium stockpiles continue to be depleted at a high rate. The uncertainty related to the remaining levels of world uranium stockpiles and to the amount of surplus defence material that will be entering the market makes it difficult to determine when a closer balance between uranium supply and demand will be reached. Information in this report provides insights into changes expected in uranium supply and demand until well into the next century. The 'Red Book', jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is the foremost reference on uranium. This world report is based on official information from 59 countries and includes compilations of statistics on resources, exploration, production and demand as of 1 January 1997. It provides substantial new information from all of the major uranium producing centres in Africa, Australia, Eastern Europe, North America and the New Independent States, including the first-ever official reports on uranium production in Estonia, Mongolia, the Russian Federation and Uzbekistan. It also contains an international expert analysis of industry statistics and worldwide projections of nuclear energy growth, uranium requirements and uranium supply

  8. Uranium resources, 1983

    International Nuclear Information System (INIS)

    The specific character of uranium as energy resources, the history of development of uranium resources, the production and reserve of uranium in the world, the prospect regarding the demand and supply of uranium, Japanese activity of exploring uranium resources in foreign countries and the state of development of uranium resources in various countries are reported. The formation of uranium deposits, the classification of uranium deposits and the reserve quantity of each type are described. As the geological environment of uranium deposits, there are six types, that is, quartz medium gravel conglomerate deposit, the deposit related to the unconformity in Proterozoic era, the dissemination type magma deposit, pegmatite deposit and contact deposit in igneaus rocks and metamorphic rocks, vein deposit, sandstone type deposit and the other types of deposit. The main features of respective types are explained. The most important uranium resources in Japan are those in the Tertiary formations, and most of the found reserve belongs to this type. The geological features, the state of yield and the scale of the deposits in Ningyotoge, Tono and Kanmon Mesozoic formation are reported. Uranium minerals, the promising districts in the world, and the matters related to the exploration and mining of uranium are described. (Kako, I.)

  10. Uranium resource assessments

    International Nuclear Information System (INIS)

    The objective of this investigation is to examine what is generally known about uranium resources, what is subject to conjecture, how well do the explorers themselves understand the occurrence of uranium, and who are the various participants in the exploration process. From this we hope to reach a better understanding of the quality of uranium resource estimates as well as the nature of the exploration process. The underlying questions will remain unanswered. But given an inability to estimate precisely our uranium resources, how much do we really need to know. To answer this latter question, the various Department of Energy needs for uranium resource estimates are examined. This allows consideration of whether or not given the absence of more complete long-term supply data and the associated problems of uranium deliverability for the electric utility industry, we are now threatened with nuclear power plants eventually standing idle due to an unanticipated lack of fuel for their reactors. Obviously this is of some consequence to the government and energy consuming public. The report is organized into four parts. Section I evaluates the uranium resource data base and the various methodologies of resource assessment. Part II describes the manner in which a private company goes about exploring for uranium and the nature of its internal need for resource information. Part III examines the structure of the industry for the purpose of determining the character of the industry with respect to resource development. Part IV arrives at conclusions about the emerging pattern of industrial behavior with respect to uranium supply and the implications this has for coping with national energy issues

  15. Uranium resource assessment activities

    International Nuclear Information System (INIS)

    The projected reductions in the growth of nuclear power have reduced the need for information on the long-term supply of uranium (i.e., beyond the year 2000). This change, plus the need to reduce budgets, has led to a modification to the program. As a consequence, the previous plans to carry on a modified National Uranium Resource Evaluation (NURE) Program, focusing on specific geologic areas of World-Class and intermediate-grade deposits, have been abandoned. The program for this fiscal year will focus on the core group of activities that were carried out here in Grand Junction prior to the start of the NURE activity. That core program will involve the collection of basic data from industry and estimation of ore reserves and production capability of the industry, as well as appraisal of potential resources based on company data and data developed in the NURE Program. Collection of other related data, on exploration activity, land holdings, and production, as well as on market activity, will also be continued. This program is expected to provide, as it has in the past, a wide spectrum of reliable information on uranium for use by government and industry explorers, producers, and consumers. The NURE Program has developed an enormous data base on the geochemical and characteristics of much of the country. In the international area, the principal activities will be carried out in cooperation with the OECD Nuclear Energy Agency and the IAEA. These activities will include the publication of biennial reports on world resources, production, and demand; cooperative studies on exploration and production technology; and work with the International Uranium Resource Evaluation Project. This project has completed the study of resources of some ten countries, and has two studies in progress

  16. Present status of development of uranium resources in foreign countries

    International Nuclear Information System (INIS)

    The book with the same title as this was published in 1981. Thereafter, the necessity to correct the contents arose, such as the remarkable change in uranium market condition and the change of uranium resource policy in Australia accompanying the change of regime, accordingly, the revision was carried out by adding more new information. As the main sources of the information collected in this book, 25 materials are shown. The confirmed resources of uranium in the free world as of the beginning of 1981 amounted to 2,293,000 t U, and the estimated additional resources were 2,720,000 t U. The political system and uranium policy, the present status of uranium export, the quantity of resources and the estimated amount of deposits, the uranium production and the status of uranium exploration and development of 25 foreign countries are reported. Japan has carried out uranium development activities in Australia, Canada, Niger, Gabon, Zambia and so on. (Kako, I.)

    2010-01-01

    With several countries currently building nuclear power plants and planning the construction of more to meet long-term increases in electricity demand, uranium resources, production and demand remain topics of notable interest. In response to the projected growth in demand for uranium and declining inventories, the uranium industry – the first critical link in the fuel supply chain for nuclear reactors – is boosting production and developing plans for further increases in the near future. Strong market conditions will, however, be necessary to trigger the investments required to meet projected demand. The "Red Book", jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. It is based on information compiled in 40 countries, including those that are major producers and consumers of uranium.

    The book of the same title as this one was published in 1983. Since then, the situation requiring the correction of the contents, such as the correction of uranium resource policy in various countries accompanying the change of uranium market condition and the change of uranium policy in Australia due to the political situation, has occurred, consequently, the revision has been made adding these new information. The confirmed resources of uranium and the resources of uranium to be added by estimation in the free world are tabulated. About each country, the organization and policy, the policy of exporting uranium and the present status of the export, the quantity of uranium resources, the production of uranium, the state of exploration and development and so on are reported. Japan has taken part in the development of uranium resources in Australia, Canada, Gabon, Zambia, Morocco, Guinea, Mali and so on. (Kako, I.)

  20. Uranium 1990 resources, production and demand

    International Nuclear Information System (INIS)

    Periodic assessments of world uranium supply and demand have been conducted by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA) since the mid 1960s. Published every two years, the report URANIUM RESOURCES, PRODUCTION AND DEMAND, commonly referred to as the RED BOOK, has become an essential reference document for nuclear planners and policy makers in the international nuclear community. The latest Red Book, published in 1990, was based on data collected mainly in early 1989. Most of the data for 1989 were therefore provisional. The STATISTICAL UPDATE 1990 provides updated 1989 data collected in 1990 and provisional for 1990

  1. Fossile fuel and uranium resources

    International Nuclear Information System (INIS)

    The world's resources of coal, lignite, oil, natural gas, shale oil and uranium are reviewed. These quantities depend on the prices which make new resources exploitable. Uranium resources are given exclusively for the USSR, Eastern Europe and China. Their value in terms of energy depends heavily on the reactor type used. All figures given are estimated to be conservative

  2. Uranium 2001: resources, production and demand

    International Nuclear Information System (INIS)

    The 'Red Book', jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. Its contents are based on official information received from 45 countries, supplemented by unofficial information for two others. This edition, the 19., presents the results of a thorough review of world uranium supply and demand as of 1 January 2001 and provides a statistical profile of the world uranium industry in the areas of exploration, resource estimates, production and reactor-related requirements. It provides substantial new information from all major uranium production centres in Africa, Australia, Eastern Europe and North America and, for the first time, includes a report on Tajikistan. This edition also features international expert analyses and projections of nuclear generating capacity and reactor-related uranium requirements through 2020. (authors)

  3. Uranium resources, production and demand

    International Nuclear Information System (INIS)

    Nuclear power-generating capacity will continue to expand, albeit at a slower pace than during the past fifteen years. This expansion must be matched by an adequately increasing supply of uranium. This report compares uranium supply and demand data in free market countries with the nuclear industry's natural uranium requirements up to the year 2000. It also reviews the status of uranium exploration, resources and production in 46 countries

  4. Uranium Resources and Supply - Demand to 2030

    International Nuclear Information System (INIS)

    Recent fluctuations in the market price for uranium have resulted in more activity in this sector over the past few years than in the preceding 20 years. Amidst this background, uranium demand is increasing. Construction of nuclear reactors is proceeding in some countries, ambitious expansion plans have been announced in others and the development of nuclear power programs to meet electricity demand and minimize greenhouse emissions in a cost effective manner is under consideration in many others. This paper reviews projections of nuclear growth and uranium demand and assesses the challenges faced by the uranium mining sector in meeting rising demand. Since the mid-1960's, an international expert committee (the 'Uranium Group') formed by the OECD Nuclear Energy Agency and the International Atomic Energy Agency has published biennially comprehensive updates on global uranium resources, production and demand (the 'Red Book'). The most recent in this series, based on 2007 data and published in June 2008, includes a supply/demand projection to 2030. However, much has changed since the data were collected for this projection and an assessment of these changes and their impact on uranium production is included in this presentation. It is concluded that world identified uranium resources (5.45 million tU recoverable at costs up to US$130/kg U, or US$50/lb U3O8) are adequate to meet projected future high case nuclear power requirements. However, recent financial market turmoil and lower uranium prices, the opaque nature of the uranium market itself, increased regulatory requirements, a scarcity of the required specialized labour and the fluctuating costs of raw materials makes the process of turning uranium resources in the ground into yellowcake in the can increasingly more challenging, particularly for new entrants. Considerable investment and expertise will be required to bring about the substantial increase in mine production required to meet future demand. (authors)

  7. Uranium 2011: Resources, Production and Demand

    International Nuclear Information System (INIS)

    In the wake of the Fukushima Daiichi nuclear power plant accident, questions are being raised about the future of the uranium market, including as regards the number of reactors expected to be built in the coming years, the amount of uranium required to meet forward demand, the adequacy of identified uranium resources to meet that demand and the ability of the sector to meet reactor requirements in a challenging investment climate. This 24. edition of the 'Red Book', a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 42 producing and consuming countries in order to address these and other questions. It offers a comprehensive review of world uranium supply and demand as well as data on global uranium exploration, resources, production and reactor-related requirements. It also provides substantive new information on established uranium production centres around the world and in countries developing production centres for the first time. Projections of nuclear generating capacity and reactor-related requirements through 2035, incorporating policy changes following the Fukushima accident, are also featured, along with an analysis of long-term uranium supply and demand issues

  8. Uranium 1999. Resources, production and demand

    International Nuclear Information System (INIS)

    In recent years, the world uranium market has been characterised by an imbalance between demand and supply and persistently depressed uranium prices. World uranium production currently satisfies between 55 and 60 per cent of the total reactor-related requirements, while the rest of the demand is met by secondary sources including the conversion of excess defence material and stockpiles, primarily from Eastern Europe. Although the future availability of these secondary sources remains unclear, projected low-cost production capability is expected to satisfy a considerable part of demand through to 2015. Information in this report provides insights into changes expected in uranium supply and demand over the next 15 years. The 'Red Book', jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is the foremost world reference on uranium. It is based on official information from 49 countries and includes compilations of statistics on resources, exploration, production and demand as of 1 January 1999. It provides substantial new information from all of the major uranium producing centres in Africa, Australia, Eastern Europe, North America and the New Independent States. It also contains an international expert analysis of industry statistics and world-wide projections of nuclear energy growth, uranium requirements and uranium supply. (authors)

  9. Uranium 2014: Resources, Production and Demand

    International Nuclear Information System (INIS)

    Uranium is the raw material used to fuel over 400 operational nuclear reactors around the world that produce large amounts of electricity and benefit from life cycle carbon emissions as low as renewable energy sources. Although a valuable commodity, declining market prices for uranium since the Fukushima Daiichi nuclear power plant accident in 2011, driven by uncertainties concerning the future of nuclear power, have led to the postponement of mine development plans in a number of countries and raised questions about continued uranium supply. This 25. edition of the 'Red Book', a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 45 producing and consuming countries in order to address these and other questions. It includes data on global uranium exploration, resources, production and reactor-related requirements. It offers updated information on established uranium production centres and mine development plans, as well as projections of nuclear generating capacity and reactor-related requirements through 2035, incorporating policy changes following the Fukushima accident, in order to address long-term uranium supply and demand issues.

  10. South African uranium resource and production capability estimates

    International Nuclear Information System (INIS)

    South Africa, along with Canada and the United States, submitted forecasts of uranium capacities and capabilites to the year 2025 for the 1979 'Red Book' edition. This report deals with the methodologies used in arriving at the South African forecasts. As the future production trends of the South African uranium producers cannot be confidently defined, chiefly because uranium is extracted as a by-product of the gold mining industry and is thus highly sensitive to market fluctuations for both uranium and gold, the Evaluation Group of the Atomic Energy Board has carried out numerous forecast exercises using current and historical norms and assuming various degrees of 'adverse', 'normal' and 'most favourable' conditions. The two exercises, which were submitted for the 'Red Book', are shown in the Appendices. This paper has been prepared for presentation to the Working Group on Methodologies for Forecasting Uranium Availability of the NEA/IAEA Steering Group on Uranium Resources

    Since the mid-1960's, with the co-operation of their member countries and states, the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA) have jointly prepared periodic updates (currently every two years) on world uranium resources, production and demand. Published by the OECD/NEA in what is commonly known as the 'Red Book', the 25. edition, released in September 2014, contains 45 national reports covering uranium producing and consuming countries and those with plans to do so. The uranium resource figures presented in the 25. edition of the Red Book are a snapshot of the situation as of 1 January 2013. Resource figures are dynamic and related to commodity prices. Despite less favourable market conditions, continued high levels of investment and associated exploration efforts have resulted in the identification of additional resources of economic interest, just as in past periods of intense exploration activity. Total identified resources (reasonably assured and inferred) as of 1 January 2013 amounted to 5 902 900 tonnes of uranium metal (tU) in the 3O8) category, an increase of 10.8% compared to 1 January 2011. In the highest cost category (3O8) which was reintroduced in 2009, total identified resources amounted to 7 635 200 tU, an increase of 7.6% compared to the total reported in 2011. The majority of the increases are a result of re-evaluations of previously identified resources and additions to known deposits, particularly in Australia, Canada, the People's Republic of China, the Czech Republic, Greenland, Kazakhstan and South Africa. Worldwide exploration and mine development expenditures in 2012 totalled USD 1.92 billion, a 21% increase over updated 2010 figures, despite declining market prices. Production in 2012 increased by 7.4% from 2011 to 58 816 tU and is expected to increase to over 59 500 tU in 2013. This recent growth is principally the result of increased production in Kazakhstan, which remains the world's largest

    International Nuclear Information System (INIS)

    The thirteenth edition of the report looks at recent developments and their impact on the short term (i.e. to the year 2005) and presents a longer term (to 2030) analysis of supply possibilities in the context of a range of requirement scenarios. It presents results of a 1989 review of uranium supply and demand in the World Outside Centrally Planned Economies Areas. It contains updated information on uranium exploration activities, resources and production for over 40 countries including a few CPEs, covering the period 1987 and 1988

  13. Topical and working papers on uranium resources and availability

    International Nuclear Information System (INIS)

    Basic topics relative to world-wide resources and availability of uranium resources; potential for recovery of uranium from mill tailings in Canada; uranium from seawater; depleted uranium as an energy source; world uranium requirements in perspective

  14. The Sustainability of Uranium Resource

    International Nuclear Information System (INIS)

    Energy is an essential element for human species; in developing countries it derives the country's economic growth, while in developed countries improves the quality of lives of people. As the world more economically developing in the future, more energy demand is expected, but this accompanies two inherent limitations: 1) the fossil fuels are limited resources and not able to supply worlds energy demands indefinitely and 2) the use of fossil fuels generates a large amount of greenhouse gas emissions harmful to the environment. 'Nuclear energy' seems to be an answer to solve these problems; increasing interests have recently shown over 'nuclear energy' as an alternative energy source to fossil fuels. Although it is a more technology-intensive energy source compared to others, however, it still needs a raw material uranium to produce electricity. Uranium is also a limited resource. For this reason, for a government to craft its long term energy policy, it needs to know how much uranium is preserved and how long it will support the country's nuclear power generation. Although many analysts so far speculate that the existing known uranium resource would be sufficient to support the nuclear power plants of the world at least until mid-century, most of those analyses assume a small rise in nuclear electricity generation in the short-term, and then a gradual decline in the long-term. Recently rising expectations and a possible renaissance for nuclear power, however, call for new analyses on this issue. This paper projects the future contribution of nuclear power to the world energy mix reflecting such a change of the atmosphere. Based on that projection, this paper analyzes how long uranium will be available for nuclear power generation

    Uranium 2003: Resources, Production and Demand paints a detailed statistical profile of the world uranium industry in the areas of exploration, resource estimates, production and reactor-related requirements. It provides substantial new information from all major uranium production centres in Africa, Australia, Eastern Europe and North America and for the first time, a report for Turkmenistan. Also included are international expert analyses and projections of nuclear generating capacity and reactor-related uranium requirements through 2020.

  16. Speculative resources of uranium. A review of International Uranium Resources Evaluation Project (IUREP) estimates 1982-1983

    International Nuclear Information System (INIS)

    On a country by country basis the International Uranium Resources Evaluation Project (IUREP) estimates 1982-1983 are reviewed. Information provided includes exploration work, airborne survey, radiometric survey, gamma-ray spectrometric survey, estimate of speculative resources, uranium occurrences, uranium deposits, uranium mineralization, agreements for uranium exploration, feasibilities studies, geological classification of resources, proposed revised resource range, production estimate of uranium

  17. Estimation of potential uranium resources

    International Nuclear Information System (INIS)

    Potential estimates, like reserves, are limited by the information on hand at the time and are not intended to indicate the ultimate resources. Potential estimates are based on geologic judgement, so their reliability is dependent on the quality and extent of geologic knowledge. Reliability differs for each of the three potential resource classes. It is greatest for probable potential resources because of the greater knowledge base resulting from the advanced stage of exploration and development in established producing districts where most of the resources in this class are located. Reliability is least for speculative potential resources because no significant deposits are known, and favorability is inferred from limited geologic data. Estimates of potential resources are revised as new geologic concepts are postulated, as new types of uranium ore bodies are discovered, and as improved geophysical and geochemical techniques are developed and applied. Advances in technology that permit the exploitation of deep or low-grade deposits, or the processing of ores of previously uneconomic metallurgical types, also will affect the estimates

  18. Limitations on progress in developing uranium resources

    International Nuclear Information System (INIS)

    Full text: Their exists a gap between the supply of uranium to nuclear power plants and the current demand for uranium for nuclear power plants. Recently rising spot and long term uranium prices provide indication that the supply of previously mined uranium is nearing an irreducible and unavailable inventory. The gap between supply and demand is very large and the inventory of proposed new mines is quite small. There clearly is a need for new uranium production and exploration, as well as increased access to previously mined uranium inventory. The author reviews the limitations to the development of new uranium sources including limitations to access to the existing inventory. The author will discuss the major limitations to progress in finding and developing uranium resources and in the availability of previously mined uranium. The major areas discussed are: 1. Financing of new production sources and new uranium mining companies, 2. Financing of uranium exploration, 3. International Legal Barriers, 4. Political and Social Constraints on Exploration and Production. 5. Environmental and Operational Permitting of Exploration, Development and Production, 6. Motivation of Uranium Producers. 7. Experienced Personnel, 8. Limitations on Developing New Techniques and Equipment to Improve the Accessibility of Uranium Resources Economically. The author will discuss these factors in relation to each of the major uranium producing countries with specific examples from each of the major producing countries to illustrate the limitations. The author will summarize the limitations and suggest the basis for overcoming these limitations as a conclusion to this paper. (author)

    Organisation for Economic Cooperation and Development. Paris

    2012-01-01

    In the wake of the Fukushima Daiichi nuclear power plant accident, questions are being raised about the future of the uranium market, including as regards the number of reactors expected to be built in the coming years, the amount of uranium required to meet forward demand, the adequacy of identified uranium resources to meet that demand and the ability of the sector to meet reactor requirements in a challenging investment climate. This 24th edition of the “Red Book”, a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 42 producing and consuming countries in order to address these and other questions. It offers a comprehensive review of world uranium supply and demand as well as data on global uranium exploration, resources, production and reactor-related requirements. It also provides substantive new information on established uranium production centres around the world and in countri...

    Based on official information received from 40 countries, Uranium 2007 provides a comprehensive review of world uranium supply and demand as of 1st January 2007, as well as data on global uranium exploration, resources, production and reactor-related requirements. It provides substantive new information from major uranium production centres in Africa, Australia, Central Asia, Eastern Europe and North America. Projections of nuclear generating capacity and reactor-related uranium requirements through 2030 are also featured, along with an analysis of long-term uranium supply and demand issues. It finds that with rising demand and declining inventories, uranium prices have increased dramatically in recent years. As a result, the uranium industry is undergoing a significant revival, bringing to an end a period of over 20 years of underinvestment.

  2. Classification of uranium reserves/resources

    International Nuclear Information System (INIS)

    Projections of future availability of uranium to meet present and future nuclear power requirements depend on the reliability of uranium resource estimates. Lack of harmony of the definition of the different classes of uranium reserves and resources between countries makes the compilation and analysis of such information difficult. The problem was accentuated in the early 1990s with the entry of uranium producing countries from the former Soviet Union, eastern Europe and China into the world uranium supply market. The need for an internationally acceptable reserve/resource classification system and terminology using market based criteria is therefore obvious. This publication was compiled from participant's contributions and findings of the Consultants Meetings on Harmonization of Uranium Resource Assessment Concepts held in Vienna from 22 to 25 June 1992, and two Consultants Meetings on the Development of a More Meaningful Classification of Uranium Resources held in Kiev, Ukraine on 24-26 April 1995 and 20-23 August 1996. This document includes 11 contributions, summary, list of participants of the Consultants Meetings. Each contribution has been indexed and provided with an abstract

  3. Uranium 2014: Resources, Production and Demand - Executive Summary

    International Nuclear Information System (INIS)

    Uranium is the raw material used to fuel over 400 operational nuclear reactors around the world that produce large amounts of electricity and benefit from life cycle carbon emissions as low as renewable energy sources. Although a valuable commodity, declining market prices for uranium since the Fukushima Daiichi nuclear power plant accident in 2011, driven by uncertainties concerning the future of nuclear power, have led to the postponement of mine development plans in a number of countries and raised questions about continued uranium supply. This 25. edition of the 'Red Book', a recognised world reference on uranium jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, provides analyses and information from 45 producing and consuming countries in order to address these and other questions. It includes data on global uranium exploration, resources, production and reactor-related requirements. It offers updated information on established uranium production centres and mine development plans, as well as projections of nuclear generating capacity and reactor-related requirements through 2035, incorporating policy changes following the Fukushima accident, in order to address long-term uranium supply and demand issues.

  4. Uranium - resources development and availability

    International Nuclear Information System (INIS)

    Australia possesses a major portion of the world's low cost uranium and it is confidently expected that further exploration will delineate yet more reserves. The level of such exploration and the rate of development of new production will remain critically dependent on world market developments. For the foreseeable future all development will be dedicated to supplying the export market. Australian government policies for uranium take account of both domestic and international concerns. With Australia, the policies act to protect the interests of the Aboriginal people affected by uranium production. In response to national interests and concerns, foreign investment in uranium production ventures is regulated in a manner which requires Australian control but allows a measure of foreign equity. Environmental concerns are recognized and projects may only be approved after comprehensive environmental protection procedures have been complied with. Without these policies public acceptability, which provides the foundations for long-term stability of the industry, would be prejudiced. On the world scene, Australia's safeguards policy serves to support international nuclear safeguards and, in particular, to honour its obligations under the Nuclear Non-Proliferation Treaty. Export policy requires that reasonable sales contract conditions apply and that fair negotiated market prices are obtained for Australia's uranium. Australia's recent re-emergence as a major producer and exporter of uranium is convincing testimony to the success of these policies. (author)

  5. Uranium resources and geology of North America

    International Nuclear Information System (INIS)

    Since about the mid seventies, the International Atomic Energy Agency has held meetings on the geology and uranium resources of different geographic regions of the world. As a continuation of this series the Technical Committee Meeting on Uranium Resources and Geology of North America was held between 1-3 September 1987 in Saskatoon, Canada. The meeting took place in the University of Saskatchewan, hosted by the Department of Geological Sciences in cooperation with the Department of Energy, Mines and Resources Canada. Thirty-six technical papers were presented to a group of over 85 participants from seven countries. These papers provided an excellent coverage of uranium occurrences and deposits and their geological framework in Canada and the USA, with analogies from other parts of the world. North America, the region dealt with in this meeting, is of eminent significance for the world's uranium production and the nuclear industry. Total WOCA U-resources according to the classification developed by the IAEA and the Nuclear Energy Agency of OECD are periodically collected by these two organisations for their report on Uranium Resources, Production and Demand. Currently total WOCA known U resources recoverable at costs of less than $130/kg U or $50/lb U3O8) amount to 3.5 million t U, of which about 25% are located in North America, while the remainder is equally divided among Africa, Australia and the rest of WOCA (Asia, Europe, South America).

  6. National Uranium Resource Evaluation, Tonopah quadrangle, Nevada

    International Nuclear Information System (INIS)

    The Tonopah Quadrangle, Nevada, was evaluated using National Uranium Resource Evaluation criteria to identify and delineate areas favorable for uranium deposits. Investigations included reconnaissance and detailed surface geologic and radiometric studies, geochemical sampling and evaluation, analysis and ground-truth followup of aerial radiometric and hydrogeochemical and stream-sediment reconnaissance data, and subsurface data evaluation. The results of these investigations indicate environments favorable for hydroallogenic uranium deposits in Miocene lacustrine sediments of the Big Smoky Valley west of Tonopah. The northern portion of the Toquima granitic pluton is favorable for authigenic uranium deposits. Environments considered unfavorable for uranium deposits include Quaternary sediments; intermediate and mafic volcanic and metavolcanic rocks; Mesozoic, Paleozoic, and Precambrian sedimentary and metasedimentary rocks; those plutonic rocks not included within favorable areas; and those felsic volcanic rocks not within the Northumberland and Mount Jefferson calderas

  8. Evaluation of uranium resources. Problems and constraints

    International Nuclear Information System (INIS)

    Growing awareness that the era of cheap energy is over has led to current efforts by governments and international organizations to examine the question of the adequacy of energy resources on a global scale. Despite the relative success of the NEA and the IAEA efforts in the study of world uranium supply, there is a need for such studies to become still more comprehensive and broader in scope. A basic problem exists with respect to the lack of a universally accepted set of resource terms by which to classify resource estimates once they are made. Often voids exist in international assessments because of insufficient data with respect to known resources and occasionally because of a lack of expertise to make the required estimates. With respect to the assessment of undiscovered uranium resources, major constraints are the relatively embryonic state of methodology for assessment of undiscovered resources and the fact that the inventory of basic geology, geochemical, and geophysical data is either incomplete or non-existent in many parts of the world. Finally, once resource estimates are made, there is often an unclear understanding about when and at what rate the resources can be made available. Hopefully, current efforts will lead to a solution to some of the principal problems and constraints which may be impeding progress toward an expansion and improvement of world uranium resource assessments.

  9. Uranium resources, production and fuel fabrication

    International Nuclear Information System (INIS)

    Almost all the known disseminated and vein-type uranium deposits in India are located in the Precambrian igneous and metamorphic complexes in the Peninsular Shield; the most significant reserves occur in the Singhbhum Thrust Belt of Bihar. Adequate resources of uranium to meet the country's fuel requirements for the nuclear power programme have been established. The Uranium Corporation of India has been operating commercially an underground uranium mine and a mill at Jaduguda (Bihar) since 1968. The uranium ore body is mined by the cut-and-fill method. The present mine workings, 530 m below ground level, comprise many innovative features, namely, a tower-mounted Koepe winder system, skip-loading with an underground crushing system, concrete headframe, etc. Surveillance, control and monitoring systems, especially required in the mining of low grade uranium ores, have been successfully introduced. The uranium mill adjacent to the mine uses the acid leach and ion-exchange processes of recovery. The effluents are suitably treated in a specially designed tailings pond. Other accessory economic minerals, namely chalcopyrite, molybdenite and magnetite, are profitably recovered as by-products. Fuel fabrication commenced in India with the manufacture of aluminium-clad metallic uranium fuel for the CIR reactor. Power reactor oxide fuel manufacture has been carried out initially at Trombay for the Rajasthan Power Reactor I (RAPP-I). For transferring the technology developed, industrial-scale plants have been set up in the Nuclear Fuel Complex (NFC) at Hyderabad for the manufacture of zirconium-clad natural uranium fuel for PHWRs and low enrichment uranium fuel for the BWR Tarapur Power Station

    Uranium for Nuclear Power: Resources, Mining and Transformation to Fuel discusses the nuclear industry and its dependence on a steady supply of competitively priced uranium as a key factor in its long-term sustainability. A better understanding of uranium ore geology and advances in exploration and mining methods will facilitate the discovery and exploitation of new uranium deposits. The practice of efficient, safe, environmentally-benign exploration, mining and milling technologies, and effective site decommissioning and remediation are also fundamental to the public image of nuclear power. This book provides a comprehensive review of developments in these areas: • Provides researchers in academia and industry with an authoritative overview of the front end of the nuclear fuel cycle • Presents a comprehensive and systematic coverage of geology, mining, and conversion to fuel, alternative fuel sources, and the environmental and social aspects • Written by leading experts in the field of nuclear power, uranium mining, milling, and geological exploration who highlight the best practices needed to ensure environmental safety

  12. Assessment of uranium resources and supply

    International Nuclear Information System (INIS)

    Uranium as nuclear fuel is an important energy resource, which generates about one-sixth of the world's total electricity generated in 1989. The current nuclear electricity generating capacity of 318 GW(e) is expected to grow by over 38% to 440 GW(e) in the year 2005. The world's uranium requirements are expected to increase similarly from about 52,000 t U in 1989 to over 70,000 t U in 2005. Beyond this time the uranium requirements are projected to reach over 80,000 t U in 2030. It was the objective of the Technical Committee Meeting on Assessment of Uranium Resources and Supply, organized by the IAEA and held in Vienna, between 29 August - 1 September 1989, to attract specialists in this field and to provide a forum for the presentation of reports on the methodologies and actual projects carried out in the different countries. Of special interest was the participation of specialists from some countries which did not or only occasionally co-operate with the IAEA in the projects related to the assessment of uranium resources and supply. A separate abstract was prepared for each of the 19 papers. Refs, figs and tabs

  13. Appraisal techniques for Indonesia's uranium resources

    International Nuclear Information System (INIS)

    Continuous monitoring and assessment of the status of supply-demand in the world market of uranium is an important or even mandatory step for Indonesia, provided the country's serious intention to enter nuclear energy era in the 2000's. This becoming more crucial when considering that there is no new installed capacity of uranium supply being planned in the world. Special attention on the technical and economic aspect of uranium deposit's appraisal could improve both the quality and quantity of the deposit. In this paper the status of our uranium resource were observed technically and economically to improve the quality of the mineral inventory and cost element with different grade and capacity. The result showed that Kalan deposit especially is feasible to be recovered and economic aspects can be optimized by developed technology. The undiscovered uranium resource in geological favorable were quantified by the volumetric and binomial distribution methods. These methods could also be served as exploration tool to select the priority of target area. (author), 5 refs; 5 tabs; 5 figs

  14. Are world uranium resources sufficient to fuel global growth in nuclear generating capacity?

    International Nuclear Information System (INIS)

    Increased uranium prices since 2003 have produced more activity in the sector than the previous 20 years. Nuclear reactor construction is proceeding in some countries, ambitious expansion plans have been announced in others and several, particularly in the developing world, are considering introducing nuclear power as a means of meeting rising electricity demand without increasing greenhouse gas emissions. Others have recently decided to either withdraw from the use of nuclear power or not proceed with development plans following the accident at the Fukushima Dai-ichi nuclear power plant in Japan in March 2011. Since the mid-1960, the OECD Nuclear Energy Agency and the International Atomic Energy Agency have jointly prepared a comprehensive update of global uranium resources, production and demand (commonly known as the 'Red Book'. The Red Book is based on government responses to a questionnaire that requests information on uranium exploration and mine development activity, resources and plans for nuclear development to 2035. This presentation provides an overview of the global situation based on the recently published 2011 edition. It features a compilation of global uranium resources, projected mine development and production capability in all the countries currently producing uranium or with plans to do so in the near future. This is compared to updated, post-Fukushima demand projections, reflecting nuclear phase-out plans announced in some countries and ambitious expansion plans of others. The 2011 Red Book shows that currently defined uranium resources are sufficient to meet high case projections of nuclear power development to 2035. (authors)

  15. The Joint NEA/IAEA Uranium Group -- its role in assessing world uranium resources, production, demand and environmental activities and issues

    International Nuclear Information System (INIS)

    In 1965 a 20-page report entitled World Uranium and Thorium Resources was published by the OECD-European Nuclear Energy Agency. Today, 35 years later, the report is jointly prepared by the OECD/Nuclear Energy Agency and the IAEA and published by the OECD. The report: Uranium Resources, Production and Demand also known as the Red Book is in its 18th edition. It is the only official publication on world uranium statistics and provides information from 45 or more countries. One aim of the Red Book is to obtain a uniform, worldwide acceptable classification of uranium resources. The Red Book provides statistics and analyses for resources, exploration, production, demand, secondary sources, surplus defence material and the supply and demand relationship. The sales records indicate that it is used as reference material for various purposes including public and private libraries, energy companies, uranium production companies, national and international organisation, universities and other research and business institutions. In 1996 a study was started which led to the 1999 report: Environmental Activities in Uranium Mining and Milling, a companion to the Red Book. This complementary report provides information on the site characterization, dismantling and decommissioning, waste management, water remediation, long term monitoring policies and regulations for 29 countries. A second report entitled 'Environmental Remediation of Uranium Production Facilities' is being prepared. (author)

  16. IAEA activities on uranium resources and production and databases for the nuclear fuel cycle

    International Nuclear Information System (INIS)

    Full text: Natural uranium (∼99.3% U-238+ ∼ 0.7 % U-235) is the basic raw material for nuclear fuel. The present generation of nuclear power reactors derive energy from the 'fission' of U-235, the only 'fissile' isotope in nature. These reactors also transmute the more abundant U-238 to man-made fissile isotope Pu-239, which could be subjected to multiple recycling, as fuel, in fast reactor for efficient utilization of natural uranium resources and to ensure long term sustainability of nuclear energy. Uranium is mostly mined and produced in countries without a nuclear power programme. On the other hand, uranium is mostly consumed in countries with nuclear power, but having no uranium. In recent years, rising expectation for nuclear power has led to increase in uranium exploration, mining and ore processing activities all over the world and several new countries, with a limited experience, have embarked on uranium exploration, mining and production. Uranium and its daughter products are radioactivity and health hazardous. Radiological safety is a major challenge in uranium production cycle and in uranium mine and mill remediation and reclamation. Another specific challenge being faced currently by uranium raw material industry is the retired or ageing manpower and lack of experienced staff around the world. The IAEA's programme on 'Uranium Resources and Production and Databases for the Nuclear Fuel Cycle' encompass all aspects of uranium geology and deposits, exploration, resources, supply and demand, uranium mining and processing, environmental issues related to uranium production cycle and databases for uranium fuel cycle. The IAEA collaborates with OECD/NEA in producing an authoritative and updated document on uranium resources, production and demand, popularly known as Red Book, which is published biennially by OECD/NEA. As a spin-off from uranium resources activities, two reports titled, 'Analysis of Uranium to 2060' and 'Red Book Retrospective - Country

  17. Reports on investigations of uranium anomalies. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    During the National Uranium Resource Evaluation (NURE) program, conducted for the US Department of Energy (DOE) by Bendix Field Engineering Corporation (BFEC), radiometric and geochemical surveys and geologic investigations detected anomalies indicative of possible uranium enrichment. Data from the Aerial Radiometric and Magnetic Survey (ARMS) and the Hydrogeochemical and Stream-Sediment Reconnaissance (HSSR), both of which were conducted on a national scale, yielded numerous anomalies that may signal areas favorable for the occurrence of uranium deposits. Results from geologic evaluations of individual 10 x 20 quadrangles for the NURE program also yielded anomalies, which could not be adequately checked during scheduled field work. Included in this volume are individual reports of field investigations for the following six areas which were shown on the basis of ARMS, HSSR, and (or) geologic data to be anomalous: (1) Hylas zone and northern Richmond basin, Virginia; (2) Sischu Creek area, Alaska; (3) Goodman-Dunbar area, Wisconsin; (4) McCaslin syncline, Wisconsin; (5) Mt. Withington Cauldron, Socorro County, New Mexico; (6) Lake Tecopa, Inyo County, California. Field checks were conducted in each case to verify an indicated anomalous condition and to determine the nature of materials causing the anomaly. The ultimate objective of work is to determine whether favorable conditions exist for the occurrence of uranium deposits in areas that either had not been previously evaluated or were evaluated before data from recent surveys were available. Most field checks were of short duration (2 to 5 days). The work was done by various investigators using different procedures, which accounts for variations in format in their reports. All papers have been abstracted and indexed

  18. Analysis on the situation of uranium resource and prospecting strategy

    International Nuclear Information System (INIS)

    The situation of world uranium market is analyzed and prognosticated and the prices may go up in 2000. The analysis of globe requests for uranium show that the tendency of excess of the requests for natural uranium over the uranium production has already begun at 1990. On the base of analyzing the trend of requests and production of uranium, it is obvious that one can't blind rely the geological resources of uranium which we have had. On the base of analysis of globe situation of uranium economy, It is considered that we must move our focal points of geological work to the target of prospecting the uranium resources of low cost. Exploring the uranium deposits of leachable sandstone type in West-North China and continuously and selectively developing commercial reserve of uranium in South China. They are considered to be the optimum strategically decisions

  19. Uranium

    The geological setting of uranium resources in the world can be divided in two basic categories of resources and are defined as reasonably assured resources, estimated additional resources and speculative resources. Tables are given to illustrate these definitions. The increasing world production of uranium despite the cutback in the nuclear industry and the uranium requirements of the future concluded these lecture notes

  20. Reprocessed Uranium: Commercial Resource or Liability

    International Nuclear Information System (INIS)

    The presence of minor uranium isotopes and their daughter products in reprocessed uranium (RepU) has logistics and cost implications for the recycle of the material. Whether or not RepU has a net asset value depends on the extent of any fuel service premiums that may apply, as well as on the evolution of prices in the various sectors of the fresh uranium fuel cycle route. Natural uranium prices today make RepU recycle look attractive but prices can and will change in the future. In addition, the economic view of recycle varies depending on whether or not the material is already recovered and stockpiled, or if it is a prospective product that could be recovered in existing or possible new reprocessing plants. This paper provides, in overview, a basis for assessing the conditions under which RepU may be considered a resource or a liability, as well as perspectives on the future evolution of front end commodity and service prices and the implications for the economic interest in recycle.

  1. National Uranium Resource Evaluation: Marfa Quadrangle, Texas

    International Nuclear Information System (INIS)

    The uranium favorability of the Marfa 10 by 20 Quadrangle, Texas, was evaluated in accordance with criteria established for the National Uranium Resource Evaluation. Surface and subsurface studies, to a 1500 m (5000 ft) depth, and chemical, petrologic, hydrogeochemical, and airborne radiometric data were employed. The entire quadrangle is in the Basin and Range Province and is characterized by Tertiary silicic volcanic rocks overlying mainly Cretaceous carbonate rocks and sandstones. Strand-plain sandstones of the Upper Cretaceous San Carlos Formation and El Picacho Formation possess many favorable characteristics and are tentatively judged as favorable for sandstone-type deposits. The Tertiary Buckshot Ignimbrite contains uranium mineralization at the Mammoth Mine. This deposit may be an example of the hydroauthigenic class; alternatively, it may have formed by reduction of uranium-bearing ground water produced during diagenesis of tuffaceous sediments of the Vieja Group. Although the presence of the deposit indicates favorability, the uncertainty in the process that formed the mineralization makes delineation of a favorable environment or area difficult. The Allen intrusions are favorable for authigenic deposits. Basin fill in several bolsons possesses characteristics that suggest favorability but which are classified as unevaluated because of insufficient data. All Precambrian, Paleozoic, other Mesozoic, and other Cenozoic environments are unfavorable

  2. National Uranium Resource Evaluation: Manhattan Quadrangle, Kansas

    International Nuclear Information System (INIS)

    Surface reconnaissance and detailed subsurface studies were conducted in the Manhattan Quadrangle, Kansas, to evaluate uranium favorability using National Uranium Resource Evaluation criteria. These studies were designed in part to follow up airborne radiometric and hydrogeochemical and stream-sediment surveys. More than 600 well records were examined in the subsurface phase of the study. Results of these investigations indicate environments favorable for channel-controlled peneconcordant sandstone uranium deposits in Cretaceous rocks and for Wyoming roll-type deposits in Pennsylvanian sandstones. The Cretaceous sandstone environments exhibit such favorable characteristics as a bottom unconformity, high bed load, braided fluvial channels, large-scale cross-bedding, and one anomalous outcrop. The Pennsylvanian sandstone environments exhibit such favorable characteristics as arkosic cross-bedded sandstones, included pyrite and organic debris, interbedded shales, and gamma-ray log anomalies. Environments considered unfavorable for uranium deposits are limestone and dolomite environments, marine black shale environments, evaporative precipitate environments, and some fluvial sandstone environments. Environments considered unevaluated because not enough data were available include Precambrian plutonic, metamorphic, and sedimentary rocks, even though a large number of thin sections were available for study

  3. Uranium--resources, sustainability and environment

    International Nuclear Information System (INIS)

    No matter which technical solutions are chosen to take nuclear power further, the basic raw material is likely to be readily available at a competitive cost. Identified world uranium resources currently stand at very safe levels, despite little exploration expenditure in recent years. These greatly understate, however, the volume of uranium which could be available if required. This provides reassurance that even ignoring any excess inventories or recycling of various materials, expanding nuclear electricity generation throughout the next century could be fuelled solely by mined supply. It is, however, unlikely that this will happen, as recycled materials will play an important part. One route to overcoming concerns about residual materials from the nuclear fuel cycle is to emphasise their potential economic value, which may provide a further boost to nuclear power as a route to environmentally sustainable development.

  4. Uranium resources of India : an introductory analysis

    International Nuclear Information System (INIS)

    Uranium mineralisation occurs in various formations of Indian geological environments. These special environments are distributed from Jammu-Kashmir to Tamilnadu and from Rajasthan to Meghalaya. Present analysis, for the first time in Hindi, brings out a detailed geological, mineralogical and genetic description of major deposits, like Jaduguda-Mohuldih sector (Bihar), Bodal-Bhandaritola (Madhya Pradesh), and minor deposits like Umra-Udaisagar (Rajasthan), Domiasiat (Meghalaya) and Arbail (Karnataka). The uranium resources position, in view of above deposits, has also been indicated for the need of Indian nuclear power programme. It is contemplated that by 2000 A.D., India will be in a position to produce 10,000 MW of nuclear power, for generation of which it has sufficient U3O8 reserves. (author). 16 refs., 1 fig., 2 tabs

  6. Maintaining the uranium resources data system and assessing the 1989 US uranium potential resources

    International Nuclear Information System (INIS)

    Under the Memorandum of Understanding (MOU) between the EIA, US Department of Energy, and the US Geological Survey (USGS), US Department of the Interior, the USGS develops estimates of uranium endowment for selected geological environments in the United States. New estimates of endowment are used to update the Uranium Resources Assessment Data (URAD) System which, beginning in 1990, is maintained for EIA by the USGS. For 1989, estimates of US undiscovered resources were generated using revised economic index values (current to December 1989) in the URAD system's cost model. The increase in the estimates for the Estimated Additional Resources (EAR) and Speculative Resources (SR) classes resulted primarily from increases in the estimates of uranium endowment for the solution-collapse, breccia-pipe uranium deposit environment in the Colorado Plateau resource region. The mean values for $30-, $50-, and $100-per-pound U3O8 forward-cost categories of EAR increased by about 8, 48, and 32 percent, respectively, as compared to 1988. Estimates of the 1989 undiscovered resources in the SR class also increased in all three forward-cost categories by 10, 5, and 9 percent, respectively. The original cost equations in the URAD System were designed to cover drilling costs related to extensive flat-lying tabular ore bodies. The equations do not adequately treat drilling costs for the smaller areas of vertical breccia pipe uranium deposits in the Colorado Plateau resource region. The development of appropriate cost equations for describing the economics of mining this type of deposit represents a major new task. 12 refs., 4 figs., 5 tabs

    This report is a general overview of the uranium mining and milling industry and its history and present status with particular reference to Utah. This volume serves two purposes: (1) it serves as a companion volume to Volume I, which is a policy analysis; and (2) it serves as one of a set of energy resource assessment studies previously performed by the authors. The following topics are covered: development of the uranium industry on the Colorado Plateau with emphasis on Utah; geology of uranium; uranium reserves; uranium exploration in Utah; uranium ore production and mining operation in Utah; uranium milling operations in Utah; utilization of uranium; uranium mill tailings; and future outlook. Appendices on pricing of uranium and incentives for production since World War II are also presented

  8. National Uranium Resource Evaluation: Okanogan Quadrangle, Washington

    International Nuclear Information System (INIS)

    The Okanogan Quadrangle, Washington, was evaluated to identify and delineate areas containing environments favorable for the occurrence of uranium deposits using criteria developed for the National Uranium Resource Evaluation program. Reconnaissance and detailed surface studies were augmented by aerial radiometric surveys and hydrogeochemical and stream-sediment reconnaissance studies. The results of the investigations indicate six environments favorable for uranium deposits. They are unclassified, anatectic, allogenic, and contact-metasomatic deposits in Late Precambrian and (or) Early Paleozoic mantling metamorphic core-complex rocks of the Kettle gneiss dome; magmatic-hydrothermal deposits in the Gold Creek pluton, the Magee Creek pluton, the Wellington Peak pluton, and the Midnite Mine pluton, all located in the southeast quadrant of the quadrangle; magmatic-hydrothermal allogenic deposits in Late Paleozoic and (or) Early Mesozoic black shales in the Castle Mountain area; allogenic deposits in Early Paleozoic metasedimentary rocks in the Harvey Creek area and in Late Precambrian metasedimentary rocks in the Blue Mountain area; and sandstone deposits in Eocene sedimentary rocks possibly present in the Enterprise Valley. Seven geologic units are considered unfavorable for uranium deposits. They are all the remaining metamorphic core-complex rocks, Precambrian metasedimentary rocks,Tertiary sedimentary and volcanic rocks, and all Pleistocene and Recent deposits; and, excluding those rocks in the unevaluated areas, include all the remaining plutonic rocks, Paleozoic miogeoclinical rocks, and Upper Paleozoic and Mesozoic eugeosynclinal rocks. Three areas, the Cobey Creek-Frosty Creek area, the Oregon City Ridge-Wilmont Creek area, and the area underlain by the Middle Cambrian Metaline Formation and its stratigraphic equivalents may possibly be favorable but are unevaluated due to lack of data

  11. Resource book: Decommissioning of contaminated facilities at Hanford

    International Nuclear Information System (INIS)

    In 1942 Hanford was commissioned as a site for the production of weapons-grade plutonium. The years since have seen the construction and operation of several generations of plutonium-producing reactors, plants for the chemical processing of irradiated fuel elements, plutonium and uranium processing and fabrication plants, and other facilities. There has also been a diversification of the Hanford site with the building of new laboratories, a fission product encapsulation plant, improved high-level waste management facilities, the Fast Flux test facility, commercial power reactors and commercial solid waste disposal facilities. Obsolescence and changing requirements will result in the deactivation or retirement of buildings, waste storage tanks, waste burial grounds and liquid waste disposal sites which have become contaminated with varying levels of radionuclides. This manual was established as a written repository of information pertinent to decommissioning planning and operations at Hanford. The Resource Book contains, in several volumes, descriptive information of the Hanford Site and general discussions of several classes of contaminated facilities found at Hanford. Supplementing these discussions are appendices containing data sheets on individual contaminated facilities and sites at Hanford. Twelve appendices are provided, corresponding to the twelve classes into which the contaminated facilities at Hanford have been organized. Within each appendix are individual data sheets containing administrative, geographical, physical, radiological, functional and decommissioning information on each facility within the class. 68 refs., 54 figs., 18 tabs

  12. Assessment of South African uranium resources: methods and results

    International Nuclear Information System (INIS)

    This paper deals primarily with the methods used by the Atomic Energy Corporation of South Africa, in arriving at the assessment of the South African uranium resources. The Resource Evaluation Group is responsible for this task, which is carried out on a continuous basis. The evaluation is done on a property-by-property basis and relies upon data submitted to the Nuclear Development Corporation of South Africa by the various companies involved in uranium mining and prospecting in South Africa. Resources are classified into Reasonably Assured (RAR), Estimated Additional (EAR) and Speculative (SR) categories as defined by the NEA/IAEA Steering Group on Uranium Resources. Each category is divided into three categories, viz, resources exploitable at less than $80/kg uranium, at $80-130/kg uranium and at $130-260/kg uranium. Resources are reported in quantities of uranium metal that could be recovered after mining and metallurgical losses have been taken into consideration. Resources in the RAR and EAR categories exploitable at costs of less than $130/kg uranium are now estimated at 460 000 t uranium which represents some 14 per cent of WOCA's (World Outside the Centrally Planned Economies Area) resources. The evaluation of a uranium venture is carried out in various steps, of which the most important, in order of implementation, are: geological interpretation, assessment of in situ resources using techniques varying from manual contouring of values, geostatistics, feasibility studies and estimation of recoverable resources. Because the choice of an evaluation method is, to some extent, dictated by statistical consderations, frequency distribution curves of the uranium grade variable are illustrated and discussed for characteristic deposits

  13. Summarized analysis on potential of uranium resources in China and strategy for uranium geologic exploration

    International Nuclear Information System (INIS)

    Through the summarized analysis on the potential of uranium resources and the degree of uranium geologic work, the author proposes the strategy of uranium geologic exploration in China as follows: the Chinese government should make a long-term program for uranium geologic exploration and insist on the basic policy to be based on domestic resources, to meet the domestic demand, to increase of the storage (the increase of storage includes active utilization of uranium resources of foreign countries), and to do the uranium exploration properly in advance. Taking the ISL-amenable sandstone-hosted uranium deposit as the major prospecting target combined with actively exploring other types of economic uranium deposits should be taken as the basic exploration strategy. Guiding by new geologic-metallogenic theory system, using advanced exploration method and technique system, GIS prediction method system and digital geologic map series to do uranium exploration are regarded as basic technical idea to accelerate ascertaining potential uranium resources in China, and to provide powerful resources guarantee for the development of China's nuclear industry.

  14. Effective use of uranium resources in light water reactor system

    International Nuclear Information System (INIS)

    We have proposed an idea of recycling uranium recovered from spent fuels of light water reactors (LWRs), where the recovered uranium is to be re-enriched by a centrifuge cascade conventionally treating natural uranium. The idea is of making it possible to reuse the fuels reproduced in a multi-cycle of re-enrichment. The uranium recycle not only economizes on uranium resources but also gets rid of accumulation of spent fuel masses. In this work, we consider additional processes for effective use of uranium, which are of re-enriching the depleted uranium. The still-more-depleted uranium is advantageous as the matrix of MOX fuels used in LWRs for the purpose of surplus plutonium disposition, because a decrease of 235U in MOX fuel is made up by increasing a dose of plutonium. However, the depleted uranium derived from the cascade enriching the recovered uranium issues a little troublesome problem of 236U concerning its existence and deliveries to the product and the waste. We made a work to investigate the burn-up performance of these remade uranium fuels in model reactors of 1.1GWe-grade PWR and the mass balance in fuel recycles. The results suggest a strategy of effective use of uranium resources in the LWR system. (author)

  15. Methodology for uranium resource estimates and reliability

    International Nuclear Information System (INIS)

    The NURE uranium assessment method has evolved from a small group of geologists estimating resources on a few lease blocks, to a national survey involving an interdisciplinary system consisting of the following: (1) geology and geologic analogs; (2) engineering and cost modeling; (3) mathematics and probability theory, psychology and elicitation of subjective judgments; and (4) computerized calculations, computer graphics, and data base management. The evolution has been spurred primarily by two objectives; (1) quantification of uncertainty, and (2) elimination of simplifying assumptions. This has resulted in a tremendous data-gathering effort and the involvement of hundreds of technical experts, many in uranium geology, but many from other fields as well. The rationality of the methods is still largely based on the concept of an analog and the observation that the results are reasonable. The reliability, or repeatability, of the assessments is reasonably guaranteed by the series of peer and superior technical reviews which has been formalized under the current methodology. The optimism or pessimism of individual geologists who make the initial assessments is tempered by the review process, resulting in a series of assessments which are a consistent, unbiased reflection of the facts. Despite the many improvements over past methods, several objectives for future development remain, primarily to reduce subjectively in utilizing factual information in the estimation of endowment, and to improve the recognition of cost uncertainties in the assessment of economic potential. The 1980 NURE assessment methodology will undoubtly be improved, but the reader is reminded that resource estimates are and always will be a forecast for the future

    wait for the results of each accelerator before planning the next one. Thus, we would wait for the results from the Tevatron before planning the LHC experiments, and wait for the LHC before planning any later stage. In reality accelerators require a long time to construct, and they require such specialized resources and human talent that delay can cripple what would be promising opportunities. In any event, we believe that the case for the linear collider is so compelling and robust that we can justify this facility on the basis of our current knowledge, even before the Tevatron and LHC experiments are done. The physics prospects for the linear collider have been studied intensively for more than a decade, and arguments for the importance of its experimental program have been developed from many different points of view. This book provides an introduction and a guide to this literature. We hope that it will allow physicists new to the consideration of linear collider physics to start from their own personal perspectives and develop their own assessments of the opportunities afforded by a linear collider

    International Nuclear Information System (INIS)

    Very little information is available to IAEA on the geology and uranium potential of Syria. In 1975 a contract was awarded to Huntings Geology and Geophysics Ltd by the Ministry of Petroleum and Mineral Resources to carry out a study of the country's mineral resources with particular reference to phosphate uranium, chrome and industrial materials. The results of this survey are not known. Apart from the assumption of some possibility of uranium recovery as a by-product from phosphate production it is assumed that the Speculative Potential is likely to be less than 1000 tonnes uranium.

  19. South African uranium resources - 1997 assessment methodology and results

    International Nuclear Information System (INIS)

    The first commercial uranium production in South Africa started in 1953 to meet the demand for British/US nuclear weapons. This early production reached its peak in 1959 and began to decline with the reduced demand. The world oil crisis in the 1970s sparked a second resurgence of increased uranium production that peaked in 1980 to over 6,000 tonnes. Poor market condition allied with increasing political isolation resulted in uranium production declining to less than a third of the levels achieved in the early 1980s. South Africa is well endowed with uranium resource. Its uranium resources in the RAR and EAR-I categories, extractable at costs of less than $80/kg U, as of 1 January 1997, are estimated to 284 400 tonnes U. Nearly two thirds of these resources are associated with the gold deposits in the Witwatersrand conglomerates. Most of the remaining resources occur in the Karoo sandstone and coal deposits.

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Thailand

    International Nuclear Information System (INIS)

    Thailand is a country with an area of 514?000 square kilometres situated in the centre of continental south-east Asia, The geology of Thailand is very varied with sedimentary formations ranging from Cambrian to Quaternary in age and including sandstones, shales, limestones of many varieties. Among the igneous rocks, granites are very important and rhyolites, tuffs diorites, basalts and ultrabasic rocks also exist. Tin is the most important mineral occurrence. Available information on the geology and mineral resources suggests that the country may contain significant resources of radioactive minerals. Favourable potential host types are; 1) uranium and thorium in monazite in beach sands and tin placer deposits; 2) uranium in sandstones, principally in Jurassic sandstones of the Khorat Plateau; 3) uranium in Tertiary lignite deposits; 4) uranium in veins in granites; 5) uranium related to fluorite deposits; 6) uranium in black shales and phosphates. Uranium mineralization in sedimentary rocks at Phu Wieng was discovered in 1970. The area has been radiometrically grid mapped and limited shallow drilling has shown continuity.of the narrow, carbonaceous, conglomeratic sandstone host bed. No uranium reserves or resources can be stated at the present time, but the favourable geology of the Khorat Plateau, the known uranium occurrence and the very small exploration coverage is possibly indicative of a good future potential. The Speculative Potential is estimated to be between 1000 and 10,000 tonnes uranium. (author)

  1. 1998 Pacific Northwest Loads and Resources Study: The White Book

    International Nuclear Information System (INIS)

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for inventory planning to determine BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The 1998 White Book is presented in two documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; and (2) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1997 Pacific Northwest Loads and Resources Study

    International Nuclear Information System (INIS)

    There is no information available at the IAEA concerning uranium occurrences and resources as well as past and present exploration. The lack of information on Nepal geology makes the selection of areas favourable for uranium exploration very difficult. It appears from the general geology of the country that the potential for new discovery in Nepal is very bad and could be defined as less than 1000 tonnes uranium

  5. Nuclear power fleets and uranium resources recovered from phosphates

    International Nuclear Information System (INIS)

    Current light water reactors (LWR) burn fissile uranium, whereas some future reactors, as Sodium fast reactors (SFR) will be capable of recycling their own plutonium and already-extracted depleted uranium. This makes them a feasible solution for the sustainable development of nuclear energy. Nonetheless, a sufficient quantity of plutonium is needed to start up an SFR, with the plutonium already being produced in light water reactors. The availability of natural uranium therefore has a direct impact on the capacity of the reactors (both LWR and SFR) that we can build. It is therefore important to have an accurate estimate of the available uranium resources in order to plan for the world's future nuclear reactor fleet. This paper discusses the correspondence between the resources (uranium and plutonium) and the nuclear power demand. Sodium fast reactors will be built in line with the availability of plutonium, including fast breeders when necessary. Different assumptions on the global uranium resources are taken into consideration. The largely quoted estimate of 22 Mt of uranium recovered for phosphate rocks can be seriously downscaled. Based on our current knowledge of phosphate resources, 4 Mt of recoverable uranium already seems to be an upper bound value. The impact of the downscaled estimate on the deployment of a nuclear fleet is assessed accordingly. (authors)

  9. Uranium in South Africa: 1983 assessment of resources and production

    International Nuclear Information System (INIS)

    NUCOR assesses South Africa's uranium resource and production capabilities on an ongoing basis. Assessments are carried out in close co-operation with the mining companies and the Government Mining Engineer. In carrying out this evaluation, the classification recommended by the NEA/IAEA Working Party on Uranium Resources is followed. In order to preserve company confidentiality, the details of the findings are released in summary form only. Within South Africa, uranium occurrences are found in Precambrian quartz-pebble conglomerates, Precambrian alkaline complexes, Cambrian to Precambrian granite gneisses, Permo-Triassic sandstones and coal, and Recent to Tertiary surficial formations. South Africa's uranium resources were reassessed during 1983 and the total recoverable resources in the Reasonably Assured and Estimated Additional Resource categories recoverable at less than $130/kg U were estimated to be 460 000 t U. This represents a decrease of 13,4% when compared with the 1981 assessment. South Africa's uranium production for 1983 amounted to 6 060 t U, a 4,21 % increase over the 1982 production of 5 816 t U. Ninety-seven percent of the production is derived from the Witwatersrand quartz-pebble conglomerates, the rest being produced as a by-product of copper mining at Palabora. South Africa maintained its position as a major low-cost uranium producer, holding 14% of the WOCA uranium resources, and during 1982 it produced 14% of WOCA's uranium. In making future production capability projections it may be safely concluded that South Africa would be able to produce uranium at substantial levels well into the next century

  10. Australia's Uranium and thorium resources and their global significance

    International Nuclear Information System (INIS)

    Full text: Full text: Australia's world-leading uranium endowment appears to result from the emplacement of uranium enriched felsic igneous rocks in three major periods during the geological evolution of the continent. Australia has over 27% of the world's total reasonably assured uranium resources (RAR) recoverable at < US$80/kgU (which approximates recent uranium spot prices). Olympic Dam is the largest known uranium deposit, containing approximately 19% of global RAR (and over 40% of global inferred resources) recoverable at < US$80/kg U; the uranium is present at low concentrations and the viability of its recovery is underpinned by co-production of copper and gold. Most of Australia's other identified resources are within Ranger, Jabiluka, Koongarra, Kintyre and Yeelirrie, the last four of which are not currently accessible for mining. In 2004, Australia's three operating uranium mines - Ranger, Olympic Dam, and Beverley -produced 22% of global production. Canada was the only country to produce more uranium (29%) and Kazakhstan (9%) ranked third. Considerably increased uranium production has been recently foreshadowed from Australia (through developing a large open pit at Olympic Dam), Canada (mainly through opening of the Cigar Lake mine), and Kazakhstan (developing several new in situ leach mines). These increases should go a long way towards satisfying demand from about 2010. Olympic Dam has sufficient resources to sustain such increased production over many decades. Thorium is expected to be used in some future generations of nuclear reactors. Australia also has major (but incompletely quantified) resources of this commodity, mainly in heavy mineral sands deposits and associated with alkaline igneous rocks. It is inevitable that the international community will be looking increasingly to Australia to sustain its vital role in providing fuels for future nuclear power generation, given its world-leading identified resources, considerable potential for new

    International Nuclear Information System (INIS)

    Reconnaissance and detailed geologic and radiometric investigations were conducted throughout the Oklahoma City Quadrangle, Oklahoma, to evaluate the uranium favorability using National Uranium Resource Evaluation criteria. Surface and subsurface studies were augmented by data from aerial radiometric surveys, hydrogeochemical and stream-sediment reconnaissance studies, basement-rock computer modeling studies, and Track Etch surveys. The results indicate that there are no environments favorable for the occurrence of uranium deposits. Environments considered unfavorable for uranium deposits include beach placers, all sandstones at the surface, limestones, and evaporites. Some shallow subsurface sandstones in the vicinity of faulted oil fields may have important uranium deposits of the type found at Cement, Oklahoma (which is just outside the quadrangle limits). Subsurface phosphatic shales and marine black shales may also have uranium deposits. Environments of these types are unevaluated because of their inaccessibility

  12. Critical review of uranium resources and production capability to 2020

    International Nuclear Information System (INIS)

    This report was prepared to assess the changing uranium supply and demand situation as well as the adequacy of uranium resources and the production capability to supply uranium concentrate to meet reactor demand through 2020. Uranium production has been meeting only 50 to 60 percent of the world requirements with the balance met from sale of excess inventory offered on the market at low prices. It is generally agreed by most specialists that the end of the excess inventory is approaching. With inventory no longer able to meet the production shortfall it is necessary to significantly expand uranium production to fill an increasing share of demand. Non-production supplies of uranium, such as the blending of highly enriched uranium (HEU) warheads to produce low enriched reactor fuel and reprocessing of spent fuel, are also expected to grow in importance as a fuel source. This analysis addresses three major concerns as follows: adequacy of resources to meet projected demand; adequacy of production capability to produce the uranium; and market prices to sustain production to fill demand. This analysis indicates uranium mine production to be the primary supply providing about 76 to 78 percent of cumulative needs through 2020. Alternative sources supplying the balance, in order of relative importance are: (1) low enriched uranium (LEU) blended from 500 tonnes of highly enriched uranium (HEU) Russian weapons, plus initial US Department of Energy (US DOE) stockpile sales (11 to 13%); (2) reprocessing of spent nuclear fuel (6%) and; (3) utility and Russian stockpiles. Further this report gives uranium production profiles by countries: CIS producers (Kazakhstan, Russian Federation, Ukraine, Uzbekistan) and other producers (Australia, Canada, China, Gabon, Mongolia, Namibia, Niger, South Africa, United States of America)

  13. Data on foreign regions where uranium resources are developed, 1

    International Nuclear Information System (INIS)

    This book was published in July, 1976, before. But thereafter, the information increased enormously, therefore the revised edition is to be published this time. The Asian regions are divided into Asia and Middle and Near East. The African regions are divided into northern, eastern, central, western and southern Africa. The general situation, the policy of uranium mining, the history of uranium ore exploration, the geological features, the uranium deposits and indications, the promising regions, the room Japan can step in, and the drawing showing the outline of geological features in respective countries are shown. In Niger, Japanese companies have taken part in the development of mines, and in Mali, the Power Reactor and Nuclear Fuel Development Corp. has carried out the exploration work. Also in Zambia, it has participated in the exploration project. The Japanese cooperation with the People's Republic of China and Thailand in uranium exploration seems to be promising. (Kako, I.)

  16. International Uranium Resources Evaluation Project (IUREP) national favourability studies: India

    International Nuclear Information System (INIS)

    Physiographically India has a total area of 3,268,010 km2 in three distinct regions. 1. The Peninsular shield in the south with an area of 823,310 km2. 2. The Himalayan mountain system with an area of 1,797,200 km2. 3. The Indo-Gangetic alluvial plain with an area of 647,500 km2. The three presently recognised major uranium provinces in India are: 1. The Singhbhum uranium province; 2. The Rajasthan uranium province, 3. The Madhya Pradesh uranium province. The Atomic Minerals Division of the Department of Atomic Energy has carried out a vigorous exploration programme since 1949 but despite their efforts a great deal of ground has still to be explored. At present, structurally controlled deposits account for most of the uranium resources of India. Uranium occurrences and deposits have been outlined in (1) Vein type deposits (the Singhbhum belt), (2) Conglomerate (Karnataka and Udaipur area, Raiasthan), (3) Sandstones (Madhra Pradesh and Swaliks, Himachal Pradesh, (4) Others such as carbonatites, marine phosphates, etc, (Mussorrie - Sahasradhara In Uttar Pradesh and Chatterpur-Saucur in Madhya Pradesh), (5) By-product Uranium in copper tailings and beach sands. India's total resources are listed as 52,538 tonnes uranium (68,300 short tons U3O8) with additional resources from monazite of 12700 tonnes uranium. In view of the wide geological favourability, the many types of occurrences already known and the vast areas of unexplored ground it is estimated that the Speculative Potential may be between 150,000 and 250,000 tonnes uranium which is Category 5.

    1998-12-01

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to the 1981 regional power sales contracts.1 Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for inventory planning to determine BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The 1998 White Book is presented in two documents: 1) this summary of Federal system and Pacific Northwest region loads and resources; and 2) a technical appendix detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1997 Pacific Northwest Loads and Resources Study. The load forecast is derived by using economic planning models to predict the loads that will be placed on electric utilities in the region. This study incorporates information on contract

  18. National uranium resource evaluation, Marble Canyon Quadrangle, Arizona and Utah

    International Nuclear Information System (INIS)

    The Marble Canyon Quadrangle (20), northeast Arizona, was evaluated to a depth of 1500 m for uranium favorability using National Uranium Resource Evaluation criteria. Known mines and prospects were examined; field reconnaissance was done in selected areas of the quadrangle; and a ground-water geochemical survey was made in the southeast third of the quadrangle. The Shinarump and Petrified Forest Members of the Triassic Chinle Formation, which is exposed in the western and northeastern parts of the quadrangle and is present beneath the surface of much of the quadrangle, were found favorable for channel-sandstone uranium deposits. A portion of the Cretaceous Toreva Formation in the southeast part of the quadrangle was found favorable for peneconcordant-sandstone uranium deposits. The western part of the quadrangle was found favorable for uranium concentrations in breccia pipes

  19. National uranium resource evaluation: Clifton Quadrangle, Arizona and New Mexico

    International Nuclear Information System (INIS)

    The Clifton Quadrangle, Arizona and New Mexico, was evaluated to identify environments and delineate areas favorable for uranium deposits. The evaluation used criteria formulated for the National Uranium Resource Evaluation program. Evidence for the evaluation was based on surface studies, hydrogeochemical and stream-sediment reconnaissance, and aerial radiometric surveys. The quadrangle encompasses parts of three physiographic provinces: the Colorado Plateau, the transition zone, and the Basin and Range. The one environment determined, during the present study, to be favorable for uranium deposits is the Whitewater Creek member of the Cooney tuff, which is favorable for magmatic-hydrothermal uranium deposits on the west side of the Bursum caldera. No other areas were favorable for uranium deposits in sandstone, limestone, volcanogenic, igneous, or metamorphic environments. The subsurface is unevaluated because of lack of information, as are areas where access is a constraint

    International Nuclear Information System (INIS)

    Geological information integration and deposit model were adopted for the potential evaluation of uranium potential in all assessment region to be predicted through countrywide and the evaluation resource of prediction areas was collected into national products of uranium resource potential. The methodology is composed of a technique system which is based on modeling representative deposits and regional metallogenic pattern, make full use of information in geology, mineral, geophysics, geochemistry and remote sensing for comprehensive assessment. This paper mainly introduced the methods of delineating prediction area and resource estimation in the evaluation process. (authors)

  2. Decision model for assessment of sandstone uranium deposits. National Uranium Resource Evaluation. Final report

    International Nuclear Information System (INIS)

    The main objective of the National Uranium Resource Evaluation (NURE) program is an estimation of the uranium resources of the United States. To achieve this objective, a geologic evaluation and resource assessment program was initiated using NTMS 20 quadrangles as the basic work unit. The evaluation activity commences with data collection within th 20 quadrangles in order to identify and delineate geologic environments that are favorable for the occurrence of uranium deposits. A favorable environment is depicted as a geologic setting that has the potential for containing at least 100 tons of U3O8 in rocks whose uranium grade exceeds 100 ppM. Geologic field reconnaissance, hydrochemical and stream sediment reconnaissance, aerial radiometric and magnetic surveys, and logging are the principal means by which favorable environments are identified. The principal investigator of each evaluation team is required to classify a favorable environments according to a preliminary classification of uranium occurrences and favorable environments. Based on this information the uranium potential in each quadrangle is estimated. The scope of this study is limited to development of an assessment procedure and a Bayesian decision model for estimating the endowed area A/sub e/ for three sandstone type uranium deposits: Wyoming roll-type, South Texas roll-type, and Uravan/Salt Wash tabular type deposits

  3. Canadian resources of uranium and thorium

    International Nuclear Information System (INIS)

    Canada has been one of the world's leading producers of uranium since the metal became important as a raw material in the development and production of atomic energy. One of the largest known deposits in the world is in Canada where present reserves represent about 37 per cent of the total among those countries that have published reserve statistics. The production of uranium has been characterized by features which are unique in Canadian mining, because the industry was created by the government at a time of emergency and, unlike other minerals, the sale of its product is controlled by the state. The rapid growth of the uranium-mining industry since World War II has been a remarkable achievement. In 1958, Canada was the world's leading producer of uranium and the value of U3O8 produced in both 1958 and 1959 exceeded the value of any other Canadian-produced metal. As an export commodity, uranium ranked fourth in value in 1959 following newsprint, wheat, and lumber. Production from 25 mines in that year was 14 462 tonnes of U3O8 valued at $345 million (all monetary values are in U.S. dollars). Since 1959, however, the decline in production, resulting from declining export markets, has been almost as rapid as the spectacular rise from 1953 to 1959. At the end of 1963 only seven mines were in production and by the end of 1965 only two mines are expected to remain in operation. (author)

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Belgium

    International Nuclear Information System (INIS)

    Uranium occurrences and resources - To date the uranium identified in Belgium is limited to a number of occurrences and none of these have as yet proved significant from a reserve or resource viewpoint. The main uranium occurrences ares (1) In the Upper Cambrian graphite schists corresponding to the culm of Sweden small zones are found (30 - 50 cm thick) with an average of 20 ppm uranium. (2) Near Vise at the base of the Carboniferous the Visean formation is discordantly superimposed on the Permian (Frasnian) and overlain by shales and phyllites. Solution pockets at the boundary contain phosphatic lenses that contain uranium values of up to 200 ppm. Autunite and Torbernite are the main uranium minerals associated with a number of complex phosphatic minerals. Within the Chalk (Maestrichtien) of the Mons basin, that is mainly in the Ciply - St. Symphorien and Baudow district. Here is found enrichment of uranium up to 140 ppm over large areas related to phosphatic chalk. The thickness of the zone varies from a few to 20 metres. However, as the P2O5 content is not high enough for the deposits to be exploited at present for phosphate there is little possibility of the uranium being concentrated at high enough levels to be exploited for itself alone. (4) Near to Vielsalm (in the Stavelot Massif) are some thin quartz veins containing small amounts of copper and uranium minerals (Torbornite). Values of up to 70 ppm are recorded. (5) A number of low uranium values are recorded associated with phosphatic nodules and zones in the Lower Pleistocene and Tertiary

    the US Department of Energy is evaluating technologies for the storage, disposal, or re-use of depleted uranium hexafluoride (UF{sub 6}). This paper discusses the following options, and provides a technology assessment for each one: (1) conversion to UO{sub 2} for use as mixed oxide duel, (2) conversion to UO{sub 2} to make DUCRETE for a multi-purpose storage container, (3) conversion to depleted uranium metal for use as shielding, (4) conversion to uranium carbide for use as high-temperature gas-cooled reactor (HTGR) fuel. In addition, conversion to U{sub 3}O{sub 8} as an option for long-term storage is discussed.

  6. Australian uranium resources and production in a world context

    International Nuclear Information System (INIS)

    The aim of the paper is to discuss Australian uranium resources and production from the perspective of ERA, the world's third-largest uranium producer, and one of only three producing uranium mining companies in Australia. ERA is a long-term supplier of uranium concentrates for the nuclear power generation industry overseas, a key part of clean global energy supply. ERA's Ranger plant was designed to produce 3,000t U3Og/yr, with expansion of the plant hi the early 90s to a 5,700t U3O8/yr capacity. Australia continues to have the worlds' largest reserves of uranium recoverable at costs of US$40 kg or less, but lags behind Canada in primary production of uranium. This paper discusses some of the reasons for the gap between resources and production, with examples from the company's own experience. Political, social and environmental factors have played a big role in the development of the uranium industry - ERA has been in the forefront of these issues as it pursues sustainable development practices

    The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to its regional power sales contracts.1 Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book will not be used in calculations for the 2002 regional power sales contract subscription process. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues.

Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. In this loads and resources study, resource availability is compared with a medium forecast of electricity consumption. The forecasted future electricity demands—firm loads—are subtracted from the projected capability of existing and “contracted for” resources to determine whether BPA and the region will be surplus or deficit. If Federal system resources are greater than loads in any particular year or month, there is a surplus of

  8. Australia's uranium resources and production in the world context

    International Nuclear Information System (INIS)

    Australia has 654 000 tonnes uranium (U) in Reasonably Assured Resources (RAR) recoverable at ≤US$40/kg U, which is the largest of all national resource estimates reported in this category. Australia also has the world's largest resources in RAR recoverable at ≤US$80/kg U, with 29% of world resources in this category. Other countries that have large resources in this category include Kazakhstan (19%), Canada (14%), South Africa (10%), Brazil (7%), Namibia (6%), Russian Federation (6%), and United States (5%). In 2000, the main developments in Australia's uranium mining industry were that production reached a record level of 8937 t U3O8 (7579 t U), and commercial operations commenced at the new in situ leach operation at Beverley during November. Australia's total production for 2000 was 27% higher than for 1999. Uranium oxide was produced at the Olympic Dam (4500 t U3O8), Ranger (4437 t U3O8) and Beverley operations, although production from Beverley for the year was not reported. Australia's share of the world's annual uranium production has increased steadily from about 10.8% (3,712 tonnes U) in 1995 to 21.9% in 2000. Throughout this period Australia has maintained its position as the world's second-largest producer of uranium, behind Canada

  9. National Uranium Resource Evaluation: Kingman Quadrangle, Arizona, Nevada, and California

    International Nuclear Information System (INIS)

    Literature research, surface geologic investigations, and rock sampling were conducted for the Kingman Quadrangle, Arizona, Nevada, and California, to identify geologic environments and delineate areas favorable for uranium deposits. Favorability criteria developed during the National Uranium Resource Evaluation program were used. The studies were augmented by aerial radiometric and hydrogeochemical and stream-sediment surveys. No environments favorable for uranium deposits of at least 100 tons U3O8 were found. Unfavorable environments include all sedimentary, igneous, and metamorphic rocks of Precambrian to Laramide age; Tertiary volcanic sequences; and Quaternary caliche. Unevaluated environments include the Bird Spring Formation and the intermontane valleys

  10. Production from new uranium mines a Cogema resources Saskatchewan perspective

    International Nuclear Information System (INIS)

    The province of Saskatchewan is best known for the large flat tracts of land in the south that are primarily used for agricultural purposes. Less well known is the fact that the northern part of the province hosts the richest uranium mines in the world. In fact, to use a petroleum analogy, Saskatchewan has been referred to as the 'Saudi Arabia' of the uranium producing countries. The mining industry in Saskatchewan is a flourishing, high technology industry and supplies approximately one-third of the annual world primary production of uranium. The purpose of this paper is to examine the uranium mining industry in Saskatchewan and why this province stands alone as the dominant uranium producer in the world and will maintain that position into the foreseeable future. As well, an overview of the significant role played by COGEMA Resources in developing the Saskatchewan uranium industry will be undertaken. This company whose roots date back almost 40 years in the province, now holds significant interests in all four of the mines currently producing uranium. With investments of over one billion dollars (U.S.) in this province, COGEMA has established itself as a long-term player in the Saskatchewan Uranium Industry. (author)

  11. National Uranium Resource Evaluation: Socorro Quadrangle, New Mexico

    International Nuclear Information System (INIS)

    The uranium resources of the Socorro 10 x 20 quadrangle, New Mexico, were evaluated to a depth of 1500 m using surface and subsurface information where available. Uranium occurrences reported in the literature were located, described, and sampled. Geochemical data from rock, stream-sediment, and water samples as well as radiometric data from aerial, ground, and drill-hole surveys were used in the evaluation. Sulfate concentrations in ground water have a highly significant correlation with uranium in the quadrangle, and may be used as a pathfinder for uranium. Interpretation of the results of this investigation suggests that the following environments are favorable for uranium deposits containing at least 100 tons of uranium present in a mineable configuration in rock having an average grade of not less than 100 ppM U3O8: (1) epigenetic deposits in sandstones of the Baca Formation and uppermost part of the underlying Crevasse Canyon Formation; (2) epigenetic deposits in the Todilto Limestone and in sandstone of the uppermost part of the underlying Entrada Sandstone; and (3) vein-type deposits in the sedimentary rocks in the Popotosa Formation, San Andres Limestone, and Madera Group. The area around the Jeter mine, along the fault contact between the Popotosa Formation and the Precambrian, appears from uranium and sulfate anomalies in the hydrogeochemical and stream-sediment surveys to have the greatest potential for undiscovered vein-type uranium deposits

  12. Uranium Exploration, Resources and Production in South Africa 2009

    International Nuclear Information System (INIS)

    The paper gives a brief history of uranium mining in South Africa. The types of uranium deposits in South Africa are described and their distribution given. The majority of uranium is hosted as a by-product in the quartz-pebble conglomerates of the Witwatersrand Basin with lesser amounts in tabular sandstone and coal hosted deposits. The exploration activities of companies operating in South Africa are discussed and the reserves and resources identified are presented. A substantial increase in reserves has been recorded over the last two years because of intensive investigation of known deposits. Only a marginal increase in total resources was reported because of a lack of “greenfield” exploration. Production is far down from the levels achieved in the 1970s and 1980s. The surge in the uranium market resulted in a number of companies investigating their production options. The recent decline in the market has slowed down some of these activities and forced the closure of an operating mine. However a new mine has come into production and feasibility studies are being carried out on other deposits. The recently promulgated Nuclear Energy Policy for the Republic of South Africa defines Necsa’s role in nuclear fuel cycle and the uranium mining industry emphasizing security of supply. South African uranium resources will be able to supply all local needs for the foreseeable future. (author)

    The Jordan Valley Quadrangle, Oregon and Idaho, was evaluated to identify and delineate areas favorable for uranium deposits in accordance with criteria developed for the National Uranium Resource Evaluation. Surface radiometric reconnaissance and geochemical sampling were used for overall evaluation of the quadrangle. Detailed rock sampling, geologic mapping, and examination of uranium deposits and occurrences were performed in areas suspected to be favorable. The northeast part of the McDermitt caldera within the quadrangle is favorable for volcanogenic deposits associated with the ring-fracture zone. The favorable area contains the Aurora uranium deposit, the Bretz mercury mine, and the Cottonwood Creek occurrence. The Triangle Ranch area and the Snake River Plain, both in the northeast part of the quadrangle, have environments that may be favorable for uranium deposits in sandstone but are considered unevaluated due to lack of subsurface data and lack of detailed investigations. Rocks in the remainder of the quadrangle are considered unfavorable for uranium deposits because of low uranium contents, basic to intermediate compositions, or lack of favorable structures.

    Five environments in the Billings Quadrangle are favorable for the occurrence of uranium deposits that could contain at least 100 tons U3O8 in rocks that have an average grade of not less than 100 ppM U3O8. The Mississippian Madison Limestone of the Pryor Mountains, a favorable environment for limestone-type deposits, contains a small mining district that has produced over 110,000 pounds of U3O8. The Cambrian Flathead Sandstone along the eastern flanks of the Beartooth Mountains is favorable for unconformity-related deposits; the area contains several uranium occurrences. The Pennsylvanian Tensleep Sandstone along the southern flanks of the Pryor Mountains is a favorable environment for Texas roll-type deposits because of lithology, structure, depositional environment, and proximity to a potential source area. The Cretaceous Lakota and Virgelle Sandstones exhibit the lithology, permeability, and volume to host sandstone-type uranium deposits. All other environments in the quadrangle are unfavorable or unevaluated

  20. National Uranium Resource Evaluation: Ashton Quadrangle, Idaho, Montana, and Wyoming

    International Nuclear Information System (INIS)

    The Ashton Quadrangle, Idaho, Montana, and Wyoming, was evaluated to identify and delineate areas containing environments favorable for uranium deposits, using criteria developed for the National Uranium Resource Evaluation program. General surface reconnaissance, radiometric traverses, and geochemical sampling were carried out in all geologic environments within the quadrangle. Aerial radiometric data were evaluated, and anomalies were examined in the field. Fourteen uranium occurrences were noted in the study area. Only one environment, the phosphorites of the Permian Phosphoria Formation, is considered favorable for uranium deposition. The unfavorable environments include: limestones, sandstones, coal and carbonaceous shales, volcanics, Precambrian metamorphics, and Tertiary basins. Unevaluated areas include the John D. Rockefeller Jr. Memorial Parkway and Yellowstone and Grand Teton National Parks, where park service regulations prohibit detailed investigations

  1. National Uranium Resource Evaluation: Sandpoint Quadrangle, Washington, Idaho, and Montana

    International Nuclear Information System (INIS)

    The Sandpoint Quadrangle, Washington, Idaho, and Montana, was evaluated to identify and delineate areas favorable for uranium deposits in accordance with criteria developed for the National Uranium Resource Evaluation. Surface radiometric reconnaissance, geochemical sampling, and reconnaissance airborne radiometric surveying were used for overall evaluation of the quadrangle. Detailed airborne radiometric surveying, geologic mapping, and other types of surface studies were used in suspected favorable areas. Results of the work indicate favorability for Wyoming roll-front type uranium deposits in conglomerates and sandstones of the Tertiary O'Brien Creek and Tiger Formations. Synorogenic plutonic rocks are considered favorable in some areas for authigenic or anatectic deposits, and radioactive postorogenic plutons are favorable for magnetic-hydrothermal deposits. Small areas containing sulfide-bearing metamorphic rocks adjacent to radioactive plutons are favorable for allogenic deposits similar to those at the Midnite Mine 10km southwest of the quadrangle. Uraniferous conglomerates of possible Tertiary age in the southwest corner of the quadrangle may be favorable for sandstone-type uranium deposits. In the Cambrian Metaline Formation, the Josephine Breccia, contains local uranium concentrations and may be favorable for unclassified-type deposits. The overlying Ordovician Ledbetter Slate also contains uranium occurrences and might contain syngenetic or hydrothermal deposits. Although thorium-rich veins in Precambrian Belt Supergroup metasedimentary rocks in Idaho contain much less uranium than thorium, they may be favorable for polymetallic vein-type uranium deposits. Late Paleozoic and Mesozoic metasedimentary and metavolcanic rocks, nonradioactive plutonic rocks, Tertiary volcanic rocks, and Quaternary deposits are considered unfavorable for uranium deposits

  2. A key point for nuclear power development, sustainability of uranium resources

    International Nuclear Information System (INIS)

    Full text: The purpose of this paper is to provide the results of a recent assessment carried out in COGEMA on the potential duration of uranium resources for nuclear energy generation; it relies upon numerous data from various sources: the 'Red Book', an international joint report of IAEA and OECD; technical documents prepared by Generation IV working groups on the uranium consumption in various types of nuclear reactors; recent and older publications - mostly from Japan - considering the extraction of uranium from sea water; and energy generation scenarios developed by the World Energy Council. The combination of demand scenarios with nuclear electricity generation scenarios leads to uranium consumption histories, which take the type of reactors into account. In the continuation of the present generation of reactors, thermal advanced reactors will probably represent the major part of the reactor fleet during the next thirty years, and most likely for more than that. Uranium prices may increase during this period; U and Pu recycling as well as recovery of U from tails may be considered. It is generally accepted that fast reactors should probably progressively replace thermal reactors during the second half of the century. Furthermore, as soon as economical trends are derived in association with the scenarios, non-realistic situations may be eliminated. For example, there is no reason to develop simultaneously on an industrial scale fast breeder reactors and extraction of uranium from seawater. We are convinced that new systems will become available around the middle of the 21st century, either fast breeders, or new sources of uranium. Thus the uranium based nuclear energy generation - i.e. fission of U and Pu generated during irradiation - is sustainable with regard to resources. However we strongly recommend to improve our present assessment of uranium resources, to validate the dates at which we shall have assurances with regard to future systems feasibility

  3. Extraction of uranium from seawater: evaluation of uranium resources and plant siting

    International Nuclear Information System (INIS)

    This report deals with the evaluation of U.S. coastal waters as a uranium resource and with the selection of a suitable site for construction of a large-scale plant for uranium extraction. Evaluation of the resource revealed that although the concentration of uranium is quite low, about 3.3 ppB in seawater of average oceanic salinity, the amount present in the total volume of the oceans is very great, some 4.5 billion metric tons. Of this, perhaps only that uranium contained in the upper 100 meters or so of the surface well-mixed layer should be considered accessible for recovery, some 160 million tonnes. The study indicated that open ocean seawater acquired for the purpose of uranium extraction would be a more favorable resource than rivers entering the sea, cooling water of power plants, or the feed or effluent streams of existing plants producing other products such as magnesium, bromine, or potable and/or agricultural water from seawater. Various considerations led to the selection of a site for a pumped seawater coastal plant at a coastal location. Puerto Yabucoa, Puerto Rico was selected. Recommendations are given for further studies. 21 figures, 8 tables

  4. National Uranium Resource Evaluation, Tularosa Quadrangle, New Mexico

    International Nuclear Information System (INIS)

    Uranium favorability of the Tularosa Quadrangle, New Mexico, was evaluated to a depth of 1500 m using National Uranium Resource Evaluation criteria. Uranium occurrences reported in the literature were located, sampled, and described in detail. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, and geochemical anomalies, interpreted from hydrogeochemical and stream-sediment reconnaissance, were also investigated. Additionally, several hundred rock samples were studied in thin section, and supplemental geochemical analyses of rock and water samples were completed. Fluorometric analyses were completed for samples from the Black Range Primitive Area to augment previously available geochemical data. Subsurface favorability was evaluated using gamma-ray logs and descriptive logs of sample cuttings. One area of uranium favorability was delineated, based on the data made available from this study. This area is the Nogal Canyon cauldron margin zone. Within the zone, characterized by concentric and radial fractures, resurgent doming, ring-dike volcanism, and intracauldron sedimentation, uranium conentration is confined to magmatic-hydrothermal and volcanogenic uranium deposits

  5. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Canada

    International Nuclear Information System (INIS)

    Exploration for mineral deposits in Canada resulted in the discovery of large uranium deposits, such as at Great. Bear Lake, Northwest Territories (1930), in the Elliot Lake area, Ontario (1949); Beaverlodge, Wollaston Lake Fold Belt and Carswell Structure in Saskatchewan (1946-1975) and many uranium occurrences in the Canadian Shield, in the Orogenic Belts and in the Platforms. Uranium output in Canada since 1942 until and including 1976 amounted to 112,000 tonnes U. Reasonably Assured uranium resources as of 1976 amounted to 167,000 tonnes U (at a price up to $40/lb. U308) and 15,000 tonnes U (at a price more than $40 up to $60/lb. U3O8). Estimated Additional uranium resources as of 1976 amounted to 392,000 tonnes U (at a price up to $40/lb. U-Og) and 264,000 tonnes U (at a price more than $40 up to $60/lb. U308). Possible further potential beyond the above mentioned classes is tentatively estimated to be in the 6th category according to NEA/IAEA favourability classification. (author)

  6. Data on foreign regions where uranium resources are developed, 2 and 3

    International Nuclear Information System (INIS)

    This book was published in July, 1976, before, and the revised edition was published at the beginning of 1982 as Part 1, Asia and Africa. This is Part 2, in which the regions of North America, Central and South America are reported, and Part 3 concerning Australian regions. The state of resource exploration and development, the policy of uranium mining, Japanese policy to advance in, the geological features and deposits, and the promising regions in Canada, USA, various countries in Central America and South America and Australia are described. Canada is one of the promising regions in the world regarding uranium deposits, and the exploration activity is brisk. In USA, the joint exploration with US persons having the mining right is the main method, and the companies must be established to develop mines. In Australia, P.N.C. Exploration P/L continues the exploration. (Kako, I.)

  7. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Sweden

    International Nuclear Information System (INIS)

    Sweden, covers an area of approx. 450 000 square kilometers. It has a population of 8 millions. With few exceptions in the northern part the access can be regarded as good. A dense network of motorroads and railroad exists. The results obtained by the exploration works combined with other available geo-information permit a separation of two principal uranium provinces in Sweden. The first one is confined to sediments of Upper Cambrian and Lower Ordovician which appears in Southern Sweden and along the border of the Caledonian mountain range in Central Sweden. The uranium occurrence are stratiform, of blackshale type which occurs in the Peltura zone of Upper Cambrian or they are associated to a phosphatite-bearing unit of Lower Ordovician overlying the Cambrian shale formation. The distribution of uranium in Upper Cambrian rocks is in general dependant on their lithology which itself is related to the paleography. This conditions explain relatively higher uranium content of the shale from Billigen.The potential resources of the province are estimated at about 1 million tonnes uranium. The second uranium province, called Arjeplog-Arvidsjaur, situated immediately south of the Arctic circle, comprises one deposit - Pleutajokk - and a group of more than twenty occurrences of similar characteristics and age (1 700 - 1 800 my.). The results of the past exploration have shown that uranium is present in different types of rocks. Because of the presence of uranium in many of the pegmatites the possibility of the formation of large low grade deposits should be tested. Favourable areas are those regions where the geological conditions are similar to the geology of the Grenville province in Canada or the Damara belt of SW-Africa. Special studies are recommended on this subject

  8. The new UN international framework classification for reserves/resources and its relation to uranium resource classification

    International Nuclear Information System (INIS)

    Resources traditionally are classified according to the degree of geological confidence and economic attractiveness. Various names are in use to describe nationally the different resource categories. Commonly, proven, probable or A+B are terms for the category RESERVES, meaning the recoverable portion of a resource under prevailing economic conditions. Since 1965 uranium resources are classified by the Nuclear Energy Agency of OECD and International Atomic Energy Agency using the terms Reasonably Assured Resources (RAR) and Estimated Additional Resources (EAR) in combination with cost categories. The definitions for RAR and EAR have been refined over the time and cost categories have been adapted according to market developments. For practical purposes a comparison of RAR and EAR with major national classification systems is provided in each of the NEA-IAEA publication on 'Uranium Resources Production and Demand' (Red Book). RAR of uranium are defined as quantities recoverable at given production costs with proven mining and processing technology, commonly RAR of the lowest cost category are referred to as Reserves. In 1992 the Committee on Energy - Working Party on Coal of the UN Economic Commission for Europe (UN/ECE) started to develop a new scheme for resource classification under the coordination of one of the authors (Kelter). The main purpose was to create an instrument permitting the classification of reserves and resources on an internationally consistent and uniform basis using market economic criteria. In April 1997 the UN/ECE approved the new 'United Nations International Framework Classification for Reserves/Resources-Solid Fuels and Mineral Commodities' at its 50th Anniversary Session. The new classification will enable the incorporation of national systems into an unified framework in order to make them compatible and comparable. Assistance will be given to economies in transition in reassessing their deposits according to market economy criteria and

  9. New developments in uranium exploration, resources, production and demand

    International Nuclear Information System (INIS)

    In view of the economic importance, the International Atomic Energy Agency and the Nuclear Energy Agency of the OECD have had a long standing interest in uranium exploration, resources, production and demand. It was the objective of this Technical Committee Meeting to bring together specialists in the field and to collect information on new developments, especially from countries which in the past considered uranium a strategic commodity and the related information as confidential or even secret. Separate abstracts were prepared for each of the 29 papers in this volume. Refs, figs, tabs, charts and maps

    Since August 1962, the OECD Nuclear Energy Agency (NEA) - from 1967 onwards in conjunction with the International Atomic Energy Agency (IAEA) - has periodically published report on uranium resources and demand. It had been recognised for some time that the uranium resource estimates given in these reports did not constitute a complete appraisal of the world's uranium resources and therefore a major study, possibly the first of its kind, was undertaken by an international group of experts on u...

  12. National Uranium Resource Evaluation: Baker Quadrangle, Oregon and Idaho

    International Nuclear Information System (INIS)

    The Baker Quadrangle, Oregon, and Idaho, was evaluated to identify areas containing geologic environments favorable for uranium deposits. The criteria used was developed for the National Uranium Resource Evaluation program. Stream-sediment reconnaissance and detailed surface studies were augmented by subsurface-data interpretion and an aerial radiometric survey. Results indicate that lower Pliocene sedimentary rocks in the Lower Powder River Valley-Virtue Flat basin are favorable characteristics, they remain unevaluated because of lack of subsurface data. Tertiary sandstones, possibly present at depth in the Long and Cascade Valleys, also remain unevaluated due to lack of subsurface data. All remaining environments in the Baker Quadrangle are unfavorable for all classes of uranium deposits

  13. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Iraq

    International Nuclear Information System (INIS)

    Iraq consists of a lowland trough lying between asymmetrical and very different upland massifs to the east, north and west and continuing southeastwards to the Persian Gulf. The region is one of crustal weakness and subsidence with relatively young plastic sedimentary rocks engulfed in downwarped, ancient, rigid and highly resistant blocks. Exploration in the 1954-55 period found some minor radioactive anomalies and very low uranium contents in limestones and phosphates. The results of an aerial radiometric survey in 1973-74 are not known to IAEA. Iraq has no reported uranium resources but there are several favourable formations which warrant a detailed survey. In view of the size of the country and the small amount of systematic exploration carried out up to the present time, the Speculative Potential is considered to lie in the 1,000 to 10,000 tonnes uranium category.

  16. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Nigaragua

    International Nuclear Information System (INIS)

    On invitation of the Nicaraguan Government, the U. S. Atomic Energy Commission conducted a reconnaissance for uranium in March, 1953. Operating and abandoned mines, as well as prospects, formations, contacts, dikes and sills enroute to these mines were tested by scintillometer. Reconnaissance included two mineralized areas exposed in windows within the volcanic belt but did not include the schists and granitic intrusions in the north eastern part of the country. No anomalous radioactivity was detected. No uranium occurrences were discovered during the 1953 reconnaissance and no uranium deposits or prospects are indicated on the metallogenetic map of Central America or in the bibliography of Nicaraguan geology. Information is net available on current exploration in Nicaragua. All subsoil mineral resources besides quarry materials belong to the state. In the interest of national defence, uranium, thorium, lithium and their derivatives, along with certain other mineral substances, may be classified as of temporary strategic interest, and their exploration or exploitation would then be subject to special laws. The Ministry of Economy may establish permanent or temporary national reserves on which mining activities are essentially precluded. Foreign nationals and corporations may acquire mineral concessions although particular regulations may be applicable to such an acquisition. Exploration of any favourable formations has been hindered by volcanic ash cover in western Nicaragua and dense vegetation in the East. Little geologic work has been done on the Paleozoic metamorphic rocks or Todos Santos Formation of the Northern Highlands. These could possibly show some potential for discovery of uranium as might the alaskites near Siuna. The potential resources of Nicaragua are estimated at less than 1,000 tonnes uranium

  17. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Turkey

    International Nuclear Information System (INIS)

    Turkey has an area of 296 185 sq mi or 767 120 square kilometers. The geology is dominated lay Tertiary and post-Tertiary rocks which are very widespread but extensive outcrops of Mesozoic rocks also occur. Paleozoic rocks, mainly gneisses, mica schists and quartzites occur in the ancient massifs, principally the Istranca massif in Thrace, the Merideres massif in western Anatolia and the Karrshir massif in central Anatolia. Prospecting for uranium began in Turkey in 1953 and the Atomic Energy Raw Materials Division of the Maden Tetkikive Arama Enstitusu (M.T.A.) was founded in 1956. By 1962 a total of 78% of the whole country had been covered by serial radiometric reconnaissance prospecting. Uranium was discovered at Kasar in western Anatolia in 1961 and several hundred tons of reserves estimated two years later. Uranium prospecting was largely recessed from 1963 to 1967. IAEA/UNDP assistance was provided in 1962-63 and 1965 and between 1974 and 1977 in a detailed exploration programme in the Kasar area. In the whole country nearly 600 anomalies and occurrences had been identified by 1963. Several occurrences principally in Western Anatolia had been assigned a small reserve. A recent official estimate places the total national reserve at 3150 tonnes uranium in the less than 30% category of reasonably assured resources. A speculative Potential of between 30,000 and 50,000 tonnes uranium is considered to be reasonable. (author)

  18. Data analysis and management for the Uranium Resource Evaluation Project

    International Nuclear Information System (INIS)

    The Department of Energy has funded a large data collection effort with the purpose of determining the US uranium resources. This Uranium Resource Evaluation (URE) Project required a large data management effort which involved collection, retrieval, processing, display, and analysis of large volumes of data. Many of the characteristics of this data processing system are relevant to other applications, particularly where routine processing involves analyses for input into numerous technical reports. The URE Project computing system has a modular program structure which has enabled a straightforward interface with both special and general graphics and analysis packages such as SAS, BMDP, and SURFACE II. Other topics include cost-effective computing, data quality, report quality computer output, and test versus production program development

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Panama

    International Nuclear Information System (INIS)

    About 20 percent of Panama has been covered by airborne radiometric surveys, largely in the Azuero-Petaquilia area. Essentially no ground examinations have been made. About one third of the country remains unmapped. Most of the rest has been examined only in rapid reconnaissance largely by the United Nations and oil companies. Detailed mapping has been confined to the Canal Zone. No uranium deposits or prospects of economic interest are known in Panama. There appears to be no information available on present exploration activities for uranium. Panama has no specific legislation relating to nuclear energy. However, all mineral deposits belong to the state, except for salt and similar materials, and are governed by the mineral resources code. There appears to be only one remote possibility for uranium mineralization in Panama, namely, sandstone-type deposits. Marginal marine and fluvial sediments, such as host sandstone-type deposits elsewhere, are most abundant 1n the lower Cenozoic parts of the Azuero and possibly Bocas del Toro basins and are probably absent or poorly developed in the Darien and Central basin. Rocks with even moderate background uranium concentrations to be leached and deposited in such sediments are confined to the silicic and alkaline Intrusive rocks of the La Yeguada Formation 1n western Panama and possibly the Rio Guayabo stock in the Sierra de Maje of eastern Panama. Only the La Yeguada Formation is extensive enough and near enough to a potential sedimentary ore host to be important. Uranium concentrations have not been measured in this unit but its silicic composition, relatively young age (with respect to other volcanic rocks in Panama) and high ash content suggest that it may have relatively high Teachable uranium content. The best areas for exploration for La Yeguada-derived sandstone-type uranium deposits would be in the Pese formation between Santiago and Chitre in the Azuero basin. Possibly favourable sandstone type exploration ground

  20. National Uranium Resource Evaluation: Newcastle Quadrangle, Wyoming and South Dakota

    International Nuclear Information System (INIS)

    Uranium resources of the Newcastle 10x20 Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the US Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and Paleozoic age below the Inyan Kara Group

  2. Estimation of intermediate grade uranium resources. Final report

    International Nuclear Information System (INIS)

    The purpose of this project is to analyze the technique currently used by DOE to estimate intermediate grade uranium (0.01 to 0.05% U3O8) and, if possible, suggest alternatives to improve the accuracy and precision of the estimate. There are three principal conclusions resulting from this study. They relate to the quantity, distribution and sampling of intermediate grade uranium. While the results of this study must be validated further, they indicate that DOE may be underestimating intermediate level reserves by 20 to 30%. Plots of grade of U3O8 versus tonnage of ore and tonnage U3O8 indicate grade-tonnage relationships that are essentially log-linear, at least down to 0.01% U3O8. Though this is not an unexpected finding, it may provide a technique for reducing the uncertainty of intermediate grade endowment. The results of this study indicate that a much lower drill hole density is necessary for DOE to estimate uranium resources than for a mining company to calculate ore resources. Though errors in local estimates will occur, they will tend to cancel over the entire deposit

  3. Uranium mining impacts on water resources in Brazil

    International Nuclear Information System (INIS)

    Uranium mining and milling activities started operations in Brazil during the 80's. The first production Center was deployed in Pocos de Caldas (CIPC) State of Minas Gerais. The mine was exhausted in 1997, after has produced only 1200 t of U3O8. The second uranium plant began the operations in Caetite (URA), Bahia State, since 1999 and keeps operations until now with an annual U3O8 production of up to 400 t. The company plans to double this mark in Caetite production center with the exploration of another uranium deposits and initiate underground operations of current open-pit mine. Simultaneously, they are seeking a license for a third plant in the State of Ceara that could produce the double of foreseen capacity in URA. This scenery drives to some issues related to the impact of uranium production on water resources of the respective watersheds. The CIPC plant is a closing mine site, which requires permanent treatment of the company due to the fact their sources of pollutants are subject to the occurrence of Acid Mine Drainage. The URA plant is located in a semi-arid region of Brazil. The extraction of uranium from the ore is achieved by means of a Heap-Leach process, which has low water demand supplied by a network of wells and from a dam, but can contribute to change the groundwater quality and in some cases the extinguishing of wells was observed. An overall assessment of these impacts in national level could produce some lessons that we must take advantage for the ongoing project of Santa Quiteria or even in future sites. (author)

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Bolivia

    International Nuclear Information System (INIS)

    Bolivia has an area of 1,098,580 square kilometers. Its capital is La Paz. The western part of the country is dominated by two ranges of the Andes Mountains, the Cordillera Occidental on the vest flank of the high plateau (Altiplano) and the Cordillera Real (or Oriental) on the east flank. The northern Andes average 5,486 meters in elevation; the southern Andes are not as lofty. The Altiplano is 3,658 to A,267 meters high and 129 km. in average width; it is the largest basin of inland drainage in South America and contains the renowned Lake Titicaca on the Peruvian-Bolivian border. The eastern tropical lowlands or pampas (Oriente) comprise about two-thirds of the country, with rain forest in the northern portion. An intermediate zone of valleys and basins lies between the eastern Andes and Oriente. Bolivia differs from other Andean countries, like Chile, Peru and Ecuador, in having large areas of Preeambrian schists, gneisses, migmatites and granites. These crop out in the eastern part of the country. Parts of these rocks contain banded iron formations (i.e., in the Muttin region) and are probably early Precambrian in age. Little systematic exploration for uranium was undertaken in Bolivia until the late 1960's. In 1967, 1968 and 1969 technical assistance was requested from, and provided by, the IAEA. This work led to evaluation of radioactive anomalies in veins of northeast Bolivia and in sandstones in the extreme southern part of the country. Although no uranium reserves are now credited to Bolivia, the geologic possibilities for several kinds of uranium deposits coupled with the relatively limited work done to date suggest that uranium orebodies will be discovered. It is estimated that the potential resources of Bolivia are in the range of 10,000 to 100,000 tonnes uranium

    1982-04-01

    The Sheridan Quadrangle of north-central Wyoming was evaluated for uranium favorability according to specific criteria of the National Uranium Resource Evaluation program. Procedures consisted of geologic and radiometric surveys; rock, water, and sediment sampling; studying well logs; and reviewing the literature. Five favorable environments were identified. These include portions of Eocene Wasatch and Upper Cretaceous Lance sandstones of the Powder River Basin and Lower Cretaceous Pryor sandstones of the Bighorn Basin. Unfavorable environments include all Precambrian, Cambrian, Ordovician, Permian, Triassic, and Middle Jurassic rocks; the Cretaceous Thermopolis, Mowry, Cody, Meeteetse, and Bearpaw Formations; the Upper Jurassic Sundance and Morrison, the Cretaceous Frontier, Meseverde, Lance, and the Paleocene Fort Union and Eocene Willwood Formations of the Bighorn Basin; the Wasatch Formation of the Powder River Basin, excluding two favorable areas and all Oligocene and Miocene rocks. Remaining rocks are unevaluated.

  6. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Guatemala

    International Nuclear Information System (INIS)

    Before 1959 a private individual (Mr. Rene Abularach) is reported to have made an airborne radiometric survey of the Sierra de las Minas and Sierra Madre Ranges. Although many anomalies were detected by this survey, none were verified in the ground survey followup, despite apparently adequate flight control. In 1968 a United Nations Special Fund Mineral Survey Project completed over 1,000 km of carborne radiometric survey with geiger counter readings at 500 m intervals. No anomalies were detected, but background radioactivity for several formations and geologic environments was established. In 1969 the Guatemalan government solicited the IAEA for technical assistance In conducting a preliminary uranium favorability study designed to formulate recommendations for a national radioactive ore prospecting program. A carborne radiometric survey was made of environments theoretically favorable for uranium deposition, with spot geological and radiometric examinations being .conducted in the more favorable areas. All Important mining regions of Guatemala except the leterites and the ultrabasics were visited. No evidence of a uranium province was observed 1n these field investigations and the recommendation was made that the government not embark on a more detailed national prospecting program at that time. At the time of completion of the IAEA-Guatemalan government (GOG) reconnaissance program in 1971, no uranium reserves or resources were known. More recent information on uranium occurrences and resources 1n Guatemala does not appear to be available. Information on more recent uranium reconnaissance than that undertaken during 1971 IAEA-GOG study is lacking.

Except for quarry materials, the state owns all minerals. The state has priority on purchase of any mineral production needed for the country

    intruded by acidic rocks. The High Cordiilera, an area of 200,000 square kilometers in northwestern Argentina contains sedimentary, metamorphic, and igneous rocks that could be favorable although the difficult topography is a restrictive influence. The distribution of uranium mineralization in various sediments and other rock types over large areas of Argentina is suggestive of widespread favorability for uranium-ore formation. Inasmuch as uranium reserves plus potential are already estimated at close to 80,000 tons U3O8, and exploration has not been exhaustively conducted, ultimate resource potential might realistically be expected to fall in the 100,000 to 500,000 ton U3O8 range

  8. Present state and problems of the measures for securing stable supply of uranium resources

    International Nuclear Information System (INIS)

    The long-term stable supply of uranium resources must be secured in order to accelerate the development and utilization of nuclear power in Japan. All uranium required in Japan is imported from foreign countries, and depends on small number of suppliers. On the use of uranium, various restrictions have been imposed by bilateral agreements from the viewpoint of nuclear non-proliferation policy. At present, the demand-supply relation in uranium market is not stringent, but in the latter half of 1980s, it is feared that it will be stringent. The prospect of the demand and supply of uranium resources, the state of securing uranium resources, the present policy on uranium resources, the necessity of establishing the new policy, and the active promotion of uranium resource measures are described. The measures to be taken are the promotion of exploration and development of mines, the participation in the management of such foreign projects, the promotion of diversifying the supply sources, the establishment of the structure to accept uranium resources, the promotion of the storage of uranium, and the rearrangement of general coordination and promotion functions for uranium resource procurement.

    Much interest has been directed to the versatile possibilities of using wood and forestry residues as well as other forms of biomass, such as annual crops and agricultural residues, for the production of liquid, gaseous and solid fuels together with various chemicals. Recently, the practice has been adopted of expressing these biorefinery conversion concepts in terms of 'green chemistry' and 'green engineering'. It can be claimed with good reason that today is the most exciting time to be working in these areas, since they comprise the essential building blocks of a new potential technology platform. On the other hand, it is a fact that the utilisation of wood and other biomass has a long history, involving a tremendous interest in creating new technologies. However, the field of green chemistry has developed through a significant range of technological breakthroughs over nearly two decades. In general, biomass-derived feedstocks are renewable (i.e., all feedstocks for both materials and energy are renewable) and also 'clean', as they have a relatively low content of sulphur, nitrogen and ash. In addition, for example, during combustion zero net emissions of CO{sub 2} can be achieved because the CO{sub 2} released from biomass will be recycled quantitatively into the plants by photosynthesis. In biorefining, it is important that the process in question is not only technically feasible but also economically sustainable, and, for this reason, its efficiency alone is not necessarily the most significant parameter. In spite of these clear considerations, the future strategic decisions are still rather complicated in view of the general challenges in society and the world, including - in addition to the need for economical energy production and the looming climate change (i.e., global warming due to emissions of greenhouse gases) - also other factors such as food production, water resources and resource depletion.

  11. IAEA Activities on Uranium Resources and Production, and Databases for the Nuclear Fuel Cycle

    International Nuclear Information System (INIS)

    In recent years rising expectation for nuclear power has led to a significant increase in the demand for uranium and in turn dramatic increases in uranium exploration, mining and ore processing activities worldwide. Several new countries, often with limited experience, have also embarked on these activities. The ultimate goal of the uranium raw material industry is to provide an adequate supply of uranium that can be delivered to the market place at a competitive price by environmentally sound, mining and milling practices. The IAEA’s programme on uranium raw material encompass all aspects of uranium geology and deposits, exploration, resources, supply and demand, uranium mining and ore processing, environmental issues in the uranium production cycle and databases for the uranium fuel cycle. Radiological safety and environmental protection are major challenges in uranium mines and mills and their remediation. The IAEA has revived its programme for the Uranium Production Site Appraisal Team (UPSAT) to assist Member States to improve operational and safety performances at uranium mines and mill sites. The present paper summarizes the ongoing activities of IAEA on uranium raw material, highlighting the status of global uranium resources, their supply and demand, the IAEA database on world uranium deposit (UDEPO) and nuclear fuel cycle information system (NFCIS), recent IAEA Technical Meetings (TM) and related ongoing Technical Cooperation (TC) projects.

  12. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Indonesia

    International Nuclear Information System (INIS)

    Indonesia is a country of south east Asia comprising a large island group extending east-west for over 3000 miles. The geology of Indonesia is fairly well known but is extremely complicated. Successive mountain movements took place around an ancient crustal area. The oldest, of Permian-Triassic age formed northeast Sumatra, northern Java and western Kalimantan. This was followed by the Sumatra orogenesis and finally in Cretaceous and Tertiary times the southern half of Java and the islands as far as New Guinea were formed. Geological studies tend to indicate that the most favourable uranium areas are likely to be in West Sumatra and West Kalimantan. Exploration by the Directorate of Survey and Geology of the National Atomic Energy Agency has been carried out on a small scale since 1961. Exploration concession have been granted to French, German and Japanese organisations. No uranium reserve or resource figures have ever been stated but small occurrences and radioactive anomalies have been found in West and South Sumatra, West and Central Kalimantan and in West Irian. Although the geology of some areas appears to be favourable, little success has attended exploration efforts to date and thus the Speculative Potential is noted as between 1,000 and 10,000 tonnes uranium.

  14. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Mexico

    International Nuclear Information System (INIS)

    Reserves of uranium are located in the north eastern part of Mexico, primarily in the states of Tamaulipas and Chihuahua. Most of the remainder of Mexico's reserves are near the Tamaulipas-Neuvo Leon state border in the Tertiary Frio Formation, where they apparently occur in the types of uranium deposits found in Texas, U.S.A. There are two deposits, La Coma and Buenavista, but nothing has been published on dimensions of the ore bodies. Forty-five miles northeast of Hermosillo, in Sonora state is the Los Amoles district where uranium is found associated with gold and other metals in low-grade deposits on the margins of a Cretaceous batholith. Another occurrence is reported in the mining district of Placer de Guadelupe and Puerto del Aire, about 40-50 km northeast of Chihuahua City, in the state of Chihuahua. Reserves of U3O8 which were published in January 1977 by Nuclear Exchange Corporation of Menlo Park, California, are listed. The government of Mexico has not estimated potential resources. It should be noted that much of Mexico appears favourable for uranium, and only 10 percent has been explored. According to NUEXCO (1977), efforts to find uranium are being increased in an attempt to supply Mexico's nuclear reactor requirements through 1990. Activity is reported to be centered in Tamaulipas and Chihuahua states and to a lesser extent in Nueva Leon, Sonora, Coahuila, and Baja California. Major effort will continue to be placed in Chihuahua state to supply the Penna Bianca mill. Correspondence between favorable geological settings for uranium and the geologic regions of Mexico is reported. Mexico is a country with considerable areas that appear promising for discovery of sandstone, vein, and tuff-related deposits. On the other hand, its potential for Precambrian conglomerate and unconformity-related deposits is limited. Considering these geologic factors, as well as the relatively limited amount of exploration done to date, a guesstimate of speculative potential

    2015-10-01

    Full Text Available The book titled Human Resources Management Challenges: Learning & Development focus on a variety of issues related to diversity of workforce and diversity management. As many researchers claim, the diversity relates to the factors that differentiate employees, such as age, gender, marital status, social status, level of disability, sexual orientation, religion, personality, physical and mental capabilities, moral values, culture, religion, even outlook. Nevertheless, the concept of diversity is not based only on differentiation related to workers’ attributes, but also on other issues, such as relationships between the organisation and workers, interests of organisations’ stakeholders etc. Diversity management is, on the other hand, perceived as an opportunity to increase the competitiveness of enterprises. Organizations might gain competitive advantage through the use of diverse workforce potential and by implementing proper structures and processes with the goal of maximising the ability of the employees to contribute to organizational objectives and to achieve the full potential unhindered by the group identities such as gender, race, nationality, age and departmental affiliation.

  18. A critical assessment of global uranium resources, including uranium in phosphate rocks, and the possible impact of uranium shortages on nuclear power fleets

    International Nuclear Information System (INIS)

    Highlights: • An estimate of all the available uranium resources has been done. • The estimate of how much uranium can be recovered from phosphate rocks is questioned. • The impact of our downscaled estimate on the deployment of a nuclear fleet is assessed accordingly. - Abstract: Future energy demand scenarios elaborated by international organisations tend to be ambitious in terms of the installed nuclear power capacity, particularly when trying to absorb the effects of a growing world population, to account for GDPs and to curb greenhouse gas emissions. Current light water reactors use thermal neutrons and burn uranium (a natural, finite resource), whereas some future Generation IV reactors using fast neutrons (starting with an initial fissile load) will be capable of recycling their own plutonium and already-extracted depleted uranium (self-sufficient or breeder fast reactors). The availability of uranium therefore has a direct impact on the capacity of the reactors that we can build. It is therefore important to have an accurate estimate of the available uranium resources in order to plan for the world’s future nuclear reactor fleet. This paper discusses the correspondence between the resources (uranium and plutonium) and the nuclear power demand as estimated by various international organisations. Furthermore, the estimate of how much uranium can be recovered from phosphate rocks is questioned and the impact of our downscaled estimate on the deployment of a nuclear fleet is assessed accordingly

  19. National Uranium Resource Evaluation: Palestine Quadrangle, Texas and Louisiana

    International Nuclear Information System (INIS)

    The uranium resource potential of the Palestine Quadrangle, Texas and Louisiana, was evaluated to a depth of 1500 m (5000 ft) using criteria established for the National Uranium Resource Evaluation program. Data derived from geochemical analyses of surface samples (substrate, soil, and stream sediment) in conjunction with hydrochemical data from water wells were used to evaluate geologic environments as being favorable or unfavorable for the occurrence of uranium deposits. Two favorable environments have been identified in the Palestine Quadrangle: potential deposits of modified Texas roll-type in fluvial channels and associated facies within the Yegua Formation, and potential occurrences along mineralization fronts associated with the Elkhart Graben and Mount Enterprise fault system. Unfavorable environments include: Cretaceous shales and limestones, Tertiary fine-grained marine sequences, Tertiary sandstone units that exhibit favorable host-rock characteristics but fail to show significant syngenetic or epigenetic mineralization, and Quaternary sands and gravels. Unevaluated units include the Woodbine Group (Upper Cretaceous), Jackson Group (Tertiary), and Catahoula Formation (Tertiary). The subsurface interval of the Jackson Group and Catahoula Formation contains depositional facies that may represent favorable environments; however, the evaluation of these units is inconclusive because of the general lack of shallow subsurface control and core material. The Woodbine Group, restricted to the subsurface except for a small exposure over Palestine Dome, occurs above 1500 m (5000 ft) in the northwest quarter of the quadrangle. The unit exhibits favorable host-rock characteristics, but the paucity of gamma logs and cores, as well as the lack of hydrogeochemical and stream-sediment reconnaissance data, makes evaluation of the unit difficult

  20. US evaluation rule of roll front uranium resources for in-situ leaching

    International Nuclear Information System (INIS)

    Nowadays the in-situ leaching of uranium is basically restricted to sandstone deposit, therefore, the importance of delineation and evaluation of this type of resources is revealed, particularly at establishing rule that can be applied for determining the value of various parameters such as thickness of ore body, grade, density, GT and so on. The measured resources,indicated resources and inferred resources as well as proven reserve and probable reserve are defined in US based on many years' practice, the evaluation rule is presented, the spacing of exploration grid related to roll type uranium resources is determined, the classification of drilling hole intercepting uranium mineralization and processing regulation for different parameters are introduced, especially in Wyoming where in-situ leach-ing uranium mines are concentrated and a series of systemic exploration and evaluation procedures of roll type uranium resources for in-situ leaching are concluded.

  2. Recent uranium supply-demand situation and market research in the world

    International Nuclear Information System (INIS)

    The uranium price (spot price) is 20 $ /1 pond U3O8 in September, 2004, which makes a new record since 20 years. By 'Uranium: Resource, Production, Demand' (RED BOOK) (2003) arranged by OECD/NEA and IAEA, uranium resource in the world is able to supply for 85 years without reprocessing and recycle. Accordingly, nuclear power development will not be controlled by uranium resource. However, uranium producer dose not develop new mine in order to fear stock of Power Company and the large amount of secondary source of supply such as enriched uranium. Now, the production rate of uranium mines in the world is about half of demand. If the situation will continue, the uranium price should become high price. Uranium demand, uranium resource, production and supply, stock, enriched uranium from Russia, excess enriched uranium in USA, plutonium, recovery of uranium, excess plutonium by disarmament, depleted uranium and uranium market are discussed.

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: France

    International Nuclear Information System (INIS)

    France, with an area of 550,000 km2, has been prospecting its territory for uranium for more than 30 years. The proven uranium reserves in all the ore categories defined by the NEA/lAEA are estimated at around 120,000 tU, of which 25,000 tU have already been mined. About 70% of these reserves are associated with granites, while the bulk of the remainder is located in Permian sediments and the last in Paleogene sediments. The prospecting effort has not been distributed equally over French territory. More than half of it - recent orogens and large basins - have been little or very little prospected. On the other hand, the Hercynian massifs and their Upper Paleozoic mantle have been systematically prospected. Nevertheless, even within the latter there is still room for further exploration: extensions of already known mineralizations both laterally and vertically, conventional mineralizations deep down or under a mantle, types of mineralizations not investigated previously (those associated with acid or intermediate vulcanism, peribatholithic shales, alkaline complexes etc.). Of course, in the areas that have not been so well explored, because they appear less favourable, there are still some possibilities, namely, in the areas of recent orogens, mineralizations associated with antemesozoic cores (same types as above) or directly associated with orogenesis (slightly to moderately metamorphic sandstone-phyllitic formations, certain sedimentary formations etc.). As for the large basins, they are capable of containing mineralizations associated with some of their formations (Paleogene of the Basin of Aquitaine etc), but they may also cover workable uranium deposits. It is possible that, in the not to distant future access may be gained to such ores in particular cases. On this basis it does not seem unreasonable to reckon with the discovering of new resources of an order of magnitude between half and the same as those already found. (author)

  5. Resource impact evaluation of in-situ uranium groundwater restoration

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the impact of restoration on the groundwater following in-situ uranium solution mining in South Texas. Restoration is necessary in order to reduce the amounts of undesired chemical constituents left in solution after mining operations have ceased, and thus return the groundwater to a quality consistent with pre-mining use and potential use. Various restoration strategies have been proposed and are discussed. Of interest are the hydrologic, environmental, social, and economic impacts of these restoration alternatives. Much of the discussion concerning groundwater restoration is based on the use of an ammonium carbonate-bicarbonate leach solution in the mining process. This has been the principal leach solution used during the early period of mining in South Texas. Recently, because of apparent difficulties in restoring ammonium to proposed or required levels, many of the companies have changed to the use of other leach solutions. Because little is known about restoration with these other leach solutions they have not been specifically addressed in this report. Likewise, we have not addressed the question of the fate of heavy metals. Following a summary of the development of South Texas in-situ mining in Chapter Two, Chapter Three describes the surface and groundwater resources of the uranium mining district. Chapter Four addresses the economics of water use, and Chapter Five is concerned with regulation of the in-situ uranium industry in Texas. A discussion of groundwater restoration alternatives and impacts is presented in Chapter Six. Chapter Seven contains a summary and a discussion, and conclusions derived from this study. Two case histories are presented in Appendices A and B

  6. Uranium favourability and evaluation in Mongolia (phase II), recent events in uranium resources and production in Mongolia

    International Nuclear Information System (INIS)

    Uranium exploration in Mongolia covered a period of over 5 decades. The main results of these activities were the discoveries of 6 uranium deposits and about 100 occurrences as well as numerous favourable indications. Sizable resources are found mainly in deposits of the sandstone, volcanic and alkaline intrusive types. Of these, the first two are considered to be of economic importance. Uranium production in Mongolia started in 1989 with the exploitation of volcanic type uranium deposits of the Mongol-Priargun metallogenic province, known as the Dornot Mine. Due to political and economic changes in the country and neighbouring areas of the Russian Federation, this uranium production was terminated in 1995. A new plan to restart production at the Mardai-gol deposits as a joint venture between Mongolia, the Russian Federation and a US company is being considered. (author)

  7. Uranium

    International Nuclear Information System (INIS)

    Canada produced one-third of the Western World's uranium production in 1989, twice as much from Saskatchewan as from Ontario, where mine closures have led to the loss of over 2,000 jobs. Canadian production in 1990 was about 8.8 Gg U. In 1990, Canada's primary producers were Denison Mines, Rio Algom, Cluff Mining, and Cameco. In Saskatchewan, there are three operations: Key Lake, Rabbit Lake/Collins Bay, and Cluff Lake. Canada stands fourth in uranium resources, but because of favourable geology remains the focus of much exploration activity, which cost about C$60 in 1989. Large stockpiles overhang the market, so new sources of uranium will not be needed before the mid 1990's, but long-term prospects seem good

  8. Developments in uranium resources, production, demand and the environment. Proceedings of a technical committee meeting

    International Nuclear Information System (INIS)

    Globalization has led to growing importance of the uranium production industries of the world's developing countries. Uranium supply from these countries could be increasingly important in satisfying worldwide reactor requirements over time. Along with the increasing contribution to worldwide uranium supply, the environmental impact of uranium production in developing countries has come under increasing scrutiny from the nuclear power industry, the end-users of this supply, and from communities impacted by uranium mining and processing. The papers presented at the meeting on 'Developments in Uranium Resources, Production, Demand and the Environment' provide an important overview of uranium production operations and of their environmental consequences in developing countries, as well as offering insight into future production plans and potential. Along with their increasing contribution to worldwide uranium supply, the environmental impact of uranium production in developing countries has come under increasing scrutiny from the nuclear power industry, the end users of this supply, and by communities impacted by uranium mining and processing. Therefore, the environmental consequences of uranium production were included in the meeting agenda as noted in the meeting title, 'Developments in uranium resources, production, demand and the environment'. Accordingly, the papers presented at this meeting are about evenly divided between discussions of known and potential uranium resources and uranium production technology and the environmental impact of uranium mining and processing, its related remediation technology and its costs. Though emphasis is placed on uranium programmes in developing countries, an overview of COGEMA's worldwide activities is also presented. This presentation provides insight into the strategies of arguably the Western world's most integrated and diversified uranium company, including the geographic diversity of its exploration and production

    International Nuclear Information System (INIS)

    A series of uranium-, thorium-, and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks have been discovered in southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of uranium-bearing quartz-pebble conglomerates to favorable rock types within a geologic terrane known from prior regional mapping. No mineral deposits have been discovered that are of current (1981) economic interest, but preliminary resource estimates indicate that over 3418 tons of uranium and over 1996 tons of thorium are present in the Medicine Bow Mountains and that over 440 tons of uranium and 6350 tons of thorium are present in Sierra Madre. Sampling has been inadequate to determine gold resources. High grade uranium deposits have not been detected by work to date but local beds of uranium-bearing conglomerate contain as much as 1380 ppM uranium over a thickness of 0.65 meters. This project has involved geologic mapping at scales from 1/6000 to 1/50,000 detailed sampling, and the evaluation of 48 diamond drill holes, but the area is too large to fully establish the economic potential with the present information. This first volume summarizes the geologic setting and geologic and geochemical characteristics of the uranium-bearing conglomerates. Volume 2 contains supporting geochemical data, lithologic logs from 48 drill holes in Precambrian rocks, and drill site geologic maps and cross-sections from most of the holes. Volume 3 is a geostatistical resource estimate of uranium and thorium in quartz-pebble conglomerates

  11. The main advance and achievements in the potential evaluation of uranium resource in China

    International Nuclear Information System (INIS)

    The national uranium resources potential evaluation is one of the important national census in China. The evaluation is based on the data and results accomplished by nuclear geological industry in last decades and wholly performed on GIS platform by absorbing related technology and geological achievement in home and broad, and has figured out 329 uranium predicted mineralization areas and estimated more than 2000000 tones resource on a national scale. Innovative achievements has been made in the classification of uranium deposit type and mineralization belt, integration of geological-geophysical-geochemical-remote sensing information and research of uranium mineralization pattern. For the first time, the potential evaluation has been performed totally by digitalisation and information, the evaluation will provide important evidence for developing middle-long term planning of uranium exploration and laid good foundation to future dynamic and regular evaluation of uranium resource in China.

  12. Uranium in Precambrian granitic rocks of the St. Francois Mountains, southeastern Missouri, with comments on uranium resource potential

    International Nuclear Information System (INIS)

    Red granites of the St. Francois Mountains are highly radioactive and contain 4 to 34 ppM uranium. The most radioactive is the Graniteville Granite which contains an average of 16.9 ppM U and 42.6 ppM Th. The Butler Hill and Breadtray Granites also contain anomalous amounts, averaging 6.2 and 5.6 ppM U and 23.5 and 20.5 ppM Th respectively. Other Precambrian granitic rocks have normal concentrations of U and Th. Fission track ''maps'' indicate that high concentrations of uranium are associated with magnetite in the red granites; this uranium is presumed to be readily leachable by hydrothermal or supergene solutions. No uranium minerals or ore grade concentrations of uranium were observed in or near the granites, but there are conceptual reasons for the possible existence of uranium deposits in intragranitic veins and onlapping Cambrian-Ordovician sedimentary rocks. Although the red granites constitute a good potential source of uranium, there is not much evidence for uranium having been mobilized. Identification of features such as lamprophyre dikes and ''episyenite'' alteration, or sedimentary rocks containing reductants, would be of value for exploration and would permit more favorable resource appraisal

  14. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Israel

    International Nuclear Information System (INIS)

    The geology of Israel is relatively simple. Most of the country is underlain by sedimentary rocks of Secondary and Tertiary age. As far as the IAEA is aware no systematic exploration has been done for conventional type uranium deposits. Israel has no uranium deposits, and no high or low-grade uranium ores. However, there are uranium 'sources' which are mainly phosphate rock.Proven phosphate reserves in Israel are estimated at about 220 million tons in five different locations. The average uranium concentration is between 100 and 170 ppm. This makes the uranium content in the proven phosphate reserves of Israel to be about 25,000 tons. Together with the possibility of additional discoveries and on the assumption that the economic conditions for the production of both phosphate and uranium become favourable the Speculative Potential is placed in the 10,000 to 50,000 tonnes uranium category.

    Even with a modest forecast of nuclear power growth for the next 25 years, it is expected that the world uranium requirements will increase. This analysis indicates uranium mine production will continue to be the primary supply of requirements through 2020. Secondary supplies, such as low enriched uranium blended from highly enriched uranium, reprocessing of spent fuel would have to make-up the remaining balance, although the contribution of US and Russian strategic stockpiles is not well known at this time.

    International Nuclear Information System (INIS)

    Determination of uranium content in Jordanian carbonate rocks has been investigated using three different detection techniques; neutron activation analysis, gamma ray spectrometry and inductively coupled plasma-mass spectrometry. The average uranium concentrations from the different methods were in good agreements. A leaching test was also performed using deionized water as a leaching solution (pH = 5.7) and it was calculated that about 9 % of the total uranium amount leached out. The results showed that carbonate rocks at Central Jordan Area contains a promising amount of uranium and more investigations need to be conducted to explore the uranium content in this area.

  20. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Cameroon

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) Mission to Cameroon. The IUREP Orientation Phase Mission to Cameroon estimates the Speculative Resources of that country to be in the order of 10 000 tonnes uranium for syenite-associated U-deposits in southern Cameroon, and in the order of 5 000 tonnes uranium for uranium deposits associated with albitized and desilicified late tectonic Panafrican granites (episyenite) and Paleozoic volcanics in northern Cameroon. No specific tonnage is given for Francevillian equivalents (DJA-Series) and for Mesozoic and Cenozoic sedimentary basins, which are thought to hold limited potential for sandstone hosted uranium. However the Douala basin, consisting of mixed marine and continental sequences merits some attention. No specific budget and programme for uranium exploration are proposed for Cameroon. Instead specific recommendations concerning specific potential environments and general recommendation concerning the methodology of exploration are made. (author)

  1. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Ghana. Draft

    International Nuclear Information System (INIS)

    The Republic of Ghana has no claimed uranium resources in the categories Reasonably Assured and Estimated Additional. The only occurrences known are within pegmatites and are of no economic importance. The IUREP Orientation Phase Mission to Ghana estimates that the Speculative Resources of the country fall between 15,000 and 40,000 tonnes uranium. The IUREP Orientation Phase Mission to Ghana believes that the Panafrican Mobile Belt has the highest uranium potential of all geological units of the country. The Obosum beds are the priority number two target. A three years exploration programme is recommended for a total cost of US $ 5,000,000. The Ghana Atomic Energy Commission and the Ghana Geological Survey provide a basic infrastructure for uranium exploration. Any future uranium development in Ghana should be embedded in a well defined national uranium policy. It is recommended that such a policy be draw, up by the Ghanaian authorities

  2. Global Uranium And Thorium Resources: Are They Adequate To Satisfy Demand Over The Next Half Century?

    Lambert, I. B.

    2012-04-01

    This presentation will consider the adequacy of global uranium and thorium resources to meet realistic nuclear power demand scenarios over the next half century. It is presented on behalf of, and based on evaluations by, the Uranium Group - a joint initiative of the OECD Nuclear Energy Agency and the International Atomic Energy Agency, of which the author is a Vice Chair. The Uranium Group produces a biennial report on Uranium Resources, Production and Demand based on information from some 40 countries involved in the nuclear fuel cycle, which also briefly reviews thorium resources. Uranium: In 2008, world production of uranium amounted to almost 44,000 tonnes (tU). This supplied approximately three-quarters of world reactor requirements (approx. 59,000 tU), the remainder being met by previously mined uranium (so-called secondary sources). Information on availability of secondary sources - which include uranium from excess inventories, dismantling nuclear warheads, tails and spent fuel reprocessing - is incomplete, but such sources are expected to decrease in market importance after 2013. In 2008, the total world Reasonably Assured plus Inferred Resources of uranium (recoverable at less than 130/kgU) amounted to 5.4 million tonnes. In addition, it is clear that there are vast amounts of uranium recoverable at higher costs in known deposits, plus many as yet undiscovered deposits. The Uranium Group has concluded that the uranium resource base is more than adequate to meet projected high-case requirements for nuclear power for at least half a century. This conclusion does not assume increasing replacement of uranium by fuels from reprocessing current reactor wastes, or by thorium, nor greater reactor efficiencies, which are likely to ameliorate future uranium demand. However, progressively increasing quantities of uranium will need to be mined, against a backdrop of the relatively small number of producing facilities around the world, geopolitical uncertainties and

  3. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Uganda

    International Nuclear Information System (INIS)

    A full report has been compiled describing the findings of the International Uranium Resources Evaluation Project (IUREP) Orientation Phase Mission to Uganda. The Mission suggest that the speculative uranium resources of the country could be within the very wide range of 0 to 105 000 tonnes of uranium metal. The Mission finds that most of these speculative resources are related to Proterozoic unconformities and to Cenozoic sandstones of the Western Rift Valley. Some potential is also associated with Post-tectonic granites. The Mission recommends to rehabilitate the Geological Survey of Uganda in order to enable it to conduct and support a uranium exploration programme for unconformity related and for standstone hosted uranium deposits. Recommended exploration methods encompass geological mapping and compilation, an airborne gamma-ray spectrometer survey north of 1 deg. North latitude, stream sediment sampling, and ground scintillometric surveys in favourable areas. Follow up work should include VLF-EM surveys, emanometry and drilling. (author)

  4. A possible metallogenic model and analysis of potential resources of Xiangshan uranium ore field

    International Nuclear Information System (INIS)

    Based on analysis of metallogenic dynamics process, geological characteristics and geochemistry of Xiangshan uranium ore field, uranium metallogenic model is discussed to guide uranium metallogenic prognosis and analysis of re- sources potential. REE geochemical characteristics, diagenetic and mineralization ages indicate that volcanic rock series in Xiangshan derived from melt of crust materials and are products of pulsating events of the same magma chamber. Di- agenesis of granitic porphyry and metallogenesis are consecutive geological events. On basis of research of fluids of wall rock alteration, REE geochemical feature and regional distribution characteristics of uranium abundance, regional uranium bearing strata are considered as the primary source for metallogenic substances, Xiangshan volcanic basin became uranium accumulative area with the help of volcanism and magmatism. Hydrothermal solution in post magmatism is rich in uranium. Interaction between fluid and rock promotes evolution of hydrothermal solution in post magmatism into metallogenic fluid, further produces process of uranium metallogenesis, eventually forms two-later spatial structure of 'volcanic lava and granitic porphyry' of uranium metallogenesis. There are greater exploration space and resources potential in the north and west parts of the ore field. Caldera, volcanic neck and volcanic pipe, and their peripheries are worth exploration. Total uranium resources of Xiangshan ore field are optimistically predicted to super-large size. (authors)

  5. Depending on scientific and technological progress to prospect for superlarge uranium deposits. Across-century target for uranium resources exploration work in China

    International Nuclear Information System (INIS)

    After over 30 years' development, uranium resources exploration work in China has resulted in the discovery of more than 10 economic types of uranium deposits in 23 provinces (regions) of the whole country and large quantities of uranium reserves have been submitted which guarantee the development of nuclear industry in China. However, characteristics such as smaller size of deposits and ore bodies, and lower ore grade of discovered China's uranium deposits have brought about a series of problems on how to economically exploit and utilize these uranium resources. To prospect for superlarge uranium deposits is a guarantee of making uranium resources essentially meet the demand for the long-term development of nuclear industry in China, and is an important way of improving economic benefits in mining China's uranium resources. It is an important mark for uranium geological exploration work to go up a new step as well. China exhibits the geological environment in which various types of superlarge uranium deposits can be formed. Having the financial support from the state to uranium resources exploration work, having professional uranium exploration teams well-experienced in ore prospecting, having modernized uranium exploration techniques and equipment and also having foreign experience in prospecting for superlarge uranium deposits as reference, it is entirely possible to find out superlarge uranium deposits in China at the end of this century and at the beginning of next century. In order to realize the objective, the most important prerequisite is that research work on metallogenetic geological theory and exploration techniques and prospecting methodology for superlarge uranium deposits must be strengthened, and technical quality of the geological teams must be improved. Within this century, prospect targets should be selected and located accurately to carry out the emphatic breakthrough in exploration strategy

  6. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Portugal

    International Nuclear Information System (INIS)

    Portugal is situated on the western edge of the Iberian Meseta. At present, its reasonably assured reserves are about 7800 t of U (including 1000 t of U at more than 830/lb U3O8) and 850 t of U in estimated additional reserves. This potential is divided between vein deposits and deposits located in the peribatholithic schists or enclaved in granite. Two main districts share these reserves - Beira at the centre of the country and Alto Alentejo in the east, approximately at the same latitude as Lisbon. In spite of the considerable prospecting activities authorized by Portugal in the Meseta area, the subject cannot yet be regarded as exhausted. Additional resources may still be located in the horizontal and vertical extensions of the vein mineralizations or schists from the already known deposits or outside the districts containing such deposits. Moreover, certain post-Palaeozoic sedimentary basins exhibit features favourable for the presence of uranium-bearing deposits and therefore deserve to be taken into consideration. However, there are as yet no examples of economic mineralization in such locations in Portugal. All things considered, we considered it reasonable to place Portugal in category No. 3 of the classiffication adopted by BJREP. (author)

    International Nuclear Information System (INIS)

    The development of the Alligator Rivers uranium resources has been dominated by socio-political problems. The author outlines the history of the discovery of uranium and gives reasons for delays in the development of the area for uranium mining. Conflicting land use interests are considered in terms of the Aboriginal Land Rights Act, the use of the area as a National Park or the development of the area by mining companies. Relevant Acts, government policies and enquiries into environmental aspects of uranium mining are discussed

  10. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Somalia

    International Nuclear Information System (INIS)

    The IUREP Orientation Phase Mission to Somalia suggests that in addition to the reasonably assured resources (RAR) of 5 000 t uranium and estimated additional resources (EAR) of 11 000 t uranium in calcrete deposits, the speculative resources (SR) could be within the wide range of 0 - 150 000 t uranium. The majority of these speculative resources are related to sandstone and calcrete deposits. The potential for magmatic hydrothermal deposits is relatively small. The Mission recommends an exploration programme of about US $ 22 000 000 to test the uranium potential of the country which is thought to be excellent. The Mission also suggests a reorganization of the Somalia Geological Survey in order to improve its efficiency. Recommended methods include geological mapping, Landsat Imagery Interpretation, airborne and ground scintillometer surveys, and geochemistry. Follow-up radiometric surveys, exploration geophysics, mineralogical studies, trenching and drilling are proposed in favourable areas

  14. Uranium resources in South Africa: a review of geology and economics

    International Nuclear Information System (INIS)

    South African uranium resources are hosted dominantly by quartz-pebble conglomerates with associated gold mineralisation, with the rest being found in sandstones and coal in the Karoo Supergroup. South Africa's known uranium resources, as at 1 January 1993, stands at 297 900 tonnes U, but in terms of economic viability in the current market situation they are substantially lower. Uranium production in South Africa is at present inextricably linked to the gold mining industry, which is in a parlous state, with many mines facing closure if a sustained rise in the gold price does not come about in the near future. Gold production is falling steadily because of the state of the gold market, and uranium is an inevitable casualty. The dependence of the uranium industry on the unpredictable and volatile gold market is unsatisfactory, and alternative sources of uranium are being sought. Attention has been focussed on the Karoo Supergroup which is the only other potentially viable source of uranium outside the Witwatersrand Basin. Factors which were re-examined are the influence of stratigraphy, source areas, tectonics and volcanism on the distribution of uranium. Uranium mineralisation in the Namaqualand Metamorphic Complex, which has associated monazite ores, is briefly mentioned. (author). 16 refs., 4 tabs., 4 figs

  15. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Nauru

    International Nuclear Information System (INIS)

    Nauru is a 21 square kilometer island in the Central Pacific. Its principle and only industry is mining of phosphate rock which is all exported. Geologically, there is little reason to assign a uranium potential to the island. However, because the phosphate does contain some uranium a category 1 potential (less than 1000 tonnes U) is assigned to Nauru. (author)

  17. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Bhutan

    International Nuclear Information System (INIS)

    It seems the uranium potential of Bhutan is very poor, due to mainly the tectonic patter of the region. However, some favourable conditions for finding small uranium deposits exist. The Pliestocen Siwalik formation is fluvitile, carbonaceous bearing sandstone. In Bhutan it is presented as a thin sequence or is absent, but in nearby Pakistan it hosts small uranium deposits. Copper occurrences are reported by Ganseer in this formation and it could supposed that they are associated by uranium mineralization. All the river draining the Himalayas have placer of uranothorium minerals. There may be localities in the southern parts of Tibet Massif disemenations of these minerals are found to be exploitable. The speculative uranium potential is less than 1000 tons

  18. Uranium mining and production: A legal perspective on regulating an important resource

    International Nuclear Information System (INIS)

    The importance of uranium can be examined from several perspectives. First, natural uranium is a strategic energy resource because it is a key ingredient for the generation of nuclear power and, therefore, it can affect the energy security of a state. Second, natural uranium is also a raw material in relative abundance throughout the world, which can, through certain steps, be transformed into nuclear explosive devices. Thus, there is both an interest in the trade of uranium resources and a need for their regulatory control. The importance of uranium to the worldwide civilian nuclear industry means that its extraction and processing - the so-called 'front end' of the nuclear fuel cycle - is of regulatory interest. Like 'ordinary' metal mining, which is generally regulated within a country, uranium mining must also be considered from the more particular perspective of regulation and control, as part of the international nuclear law regime that is applied to the entire nuclear fuel cycle. The present overview of the regulatory role in overseeing and controlling uranium mining and production will outline the regulation of this resource from an international level, both from early days to the present day. Uranium mining is not regulated internationally; rather, it is a state responsibility. However, developments at the international level have, over time, led to better national regulation. One can note several changes in the approach to the uranium industry since the time that uranium was first mined on a significant scale, so that today the mining and trade of uranium is a well-established and regulated industry much less marked by secrecy and Cold War sentiment. At the same time, it is informed by international standards and conventions, proliferation concerns and a modern regard for environmental protection and the health and safety of workers and the public.

  19. Potential and existing uranium resources of the Middle East and North Africa

    International Nuclear Information System (INIS)

    Full text: This study integrated evidences from structural frameworks, geologic environments and geochemical-metalogenic indicators for uranium deposits to predict some uranium-bearing provinces in the studied countries (Egypt, Iran, Iraq, Jordan, Saudi Arabia, Sudan, Syria, Turkey, UAE, Oman, Qatar, Kuwait and Yemen, Algeria, Libya, Morocco and Tunisia). The study found that the Pan-African granites are one of the most suitable environments to host veintype uranium deposits. The uranium mineralizations are hosted in these granites within some favorable structures such as faults and fractures. The uranium minerals are mainly secondary (primarily uranophane) and occasionally some pitchblende and uraninites are present. They are associated with sulphide as pyrite, chalcopyrite, galena, sphalerite and molybdenite. The gangues minerals are mainly iron, manganese oxides and fluorite. The most associated alteration features with this gangue are hematitization, silicification with black silica veins, carbonetization and the presence of fluorite. Volcanic rocks represented another potential source for uranium in many of the studied countries. The volcanics range in age from 74 to 302 MY and some of them host uranium or uranium/thorium mineralization. The presence of intra-cratonic basins is also observed within many basement rock exposures in the study area. Often these basins are filled with late-Proterozoic molasses-type sediments such as the Hammamat series in Egypt, and can form important uranium traps according to their geochemical and geological characteristics. This feature is well known in many of the studied countries especially in Algeria, Egypt and Saudi Arabia. The present study also documented evidence of the presence of intra-cratonic basins filled with Paleozoic sequences; the lower horizons of these sequences have potential for hosting uranium resources. This was noted in Libya (Morzok basin) and in Egypt (Wadi El Kharite basin). The Unconformity uranium

  2. Statistical model of global uranium resources and long-term availability

    Directory of Open Access Journals (Sweden)

    Monnet Antoine

    2016-01-01

    Full Text Available Most recent studies on the long-term supply of uranium make simplistic assumptions on the available resources and their production costs. Some consider the whole uranium quantities in the Earth's crust and then estimate the production costs based on the ore grade only, disregarding the size of ore bodies and the mining techniques. Other studies consider the resources reported by countries for a given cost category, disregarding undiscovered or unreported quantities. In both cases, the resource estimations are sorted following a cost merit order. In this paper, we describe a methodology based on “geological environments”. It provides a more detailed resource estimation and it is more flexible regarding cost modelling. The global uranium resource estimation introduced in this paper results from the sum of independent resource estimations from different geological environments. A geological environment is defined by its own geographical boundaries, resource dispersion (average grade and size of ore bodies and their variance, and cost function. With this definition, uranium resources are considered within ore bodies. The deposit breakdown of resources is modelled using a bivariate statistical approach where size and grade are the two random variables. This makes resource estimates possible for individual projects. Adding up all geological environments provides a repartition of all Earth's crust resources in which ore bodies are sorted by size and grade. This subset-based estimation is convenient to model specific cost structures.

  3. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Bolivia. Draft

    International Nuclear Information System (INIS)

    The uranium exploration done so far in Bolivia has been carried out by COBOEN, partly with IAEA support, and AGIP S.p.A. of Italy, which between 1974 and 1978 explored four areas in various parts of Bolivia under a production sharing contract with COBOEN. The basic objective of the International Uranium Resources Evaluation Project (IUREP) is to 'review the present body of knowledge pertinent to the existence of uranium resources, to review and evaluate the potential for discovery of additional uranium resources, and to suggest new exploitation efforts which might be carried out in promising areas in collaboration with the country concerned'. Following the initial bibliographic study which formed Phase I of IUREP, it was envisaged that a further assessment in cooperation with, and within, the country concerned would provide a better delineation of areas of high potential and a more reliable estimate as to the degree of favourability for the discovery of additional uranium resources. It was planned that such work would be accomplished through field missions to the country concerned and that these field missions and the resulting report would be known as the Orientation Phase of IUREP. The purpose of the Orientation Phase mission to Bolivia was a) to develop a better understanding of the uranium potential of the country, b) to make an estimate of the Speculative Resources of the country, c) to delineate areas favourable for the discovery of these uranium resources, d) to make recommendations as appropriate on the best methods for evaluating the favourable areas, operating procedures and estimated possible costs, e) to develop the logistical data required to carry out any possible further work, and f) to compile a report which would be immediately available to the Bolivian authorities. The mission reports contains information about a general introduction, non-uranium exploration and mining in Bolivia, manpower in exploration, geological review of Bolivia, past uranium

    As an important base of pegmatite type uranium deposit in China, Danfeng orefield has its special metallogenic condition and ore-controlling factors. Through the comprehensive analysis of prediction elements, such as uranium source formation, pegmatite vein, ground surface radioactive anomaly, stream sediment uranium anomaly, we had outlined two prospective areas of class Ⅰ and Ⅱ, one class Ⅲ prospective area respectively with MRAS software. The deep and peripheral part of Guangshigou and Chenjiazhuang deposits are the most beneficial space for further prospecting. Taoping and Shimen prospective area are the new favorable ore-forming regions. (authors)

    International Nuclear Information System (INIS)

    Cyprus has a large variety of rocks ranging from perhaps Pre-cambrian to Recent. Many of the rocks are plutonic in origin and include gabbros and granophyres but the most extensive rock is diabase. Despite extensive exploration, both past and present for other metals nothing is known about any specific uranium exploration and there is no record of any uranium discoveries in this extensive general exploration. For these reasons it is considered that the Speculative Potential is probably best stated as less than 1000 tonnes uranium. (author)

  7. National uranium resource evaluation: Silver City Quadrangle, New Mexico and Arizona

    International Nuclear Information System (INIS)

    Reconnaissance and detailed geologic, geochemical, and radiometric studies were conducted throughout the Silver City Quadrangle, New Mexico and Arizona, to identify environments and delineate areas favorable for the occurrence of uranium deposits using National Uranium Resource Evaluation criteria. Surface and limited subsurface studies were augmented by aerial radiometric and hydrogeochemical and stream-sediment reconnaissance surveys. Results of the investigations indicate several areas favorable for magmatic-hydrothermal uranium deposits. They include Precambrian granitic, gneissic, and diabasic rocks; the Cretaceous Beartooth Quartzite where it overlies Precambrian granite; certain Laramide to mid-Tertiary monzonitic rocks; and Tertiary volcanic rocks adjacent to a quartz monzonitic stock. Studies also indicate environments favorable for allogenic deposits in the Tyrone laccolith and for uranium deposits in upper Cenozoic volcaniclastic lacustrine rocks. Formations judged unfavorable for magmatic-hydrothermal uranium deposits include large areas of Precambrian granitic and metamorphic rocks, almost all Laramide and mid-Tertiary intrusive rocks, and intruded Paleozoic and Cretaceous carbonate rocks. Precambrian metamorphic rocks are also considered unfavorable for contact metasomatic as well as for unconformity-related and vein-type uranium deposits. The entire Paleozoic and Cretaceous sedimentary section is considered unfavorable for sandstone and marine-black-shale uranium deposits. Moreover, mid-Tertiary rocks were judged unfavorable for volcanogenic uranium deposits, and upper Cenozoic basin-fill and surficial deposits are unfavorable for sandstone-type deposits and for uranium deposits associated with volcaniclastic lacustrine environments

    Charepon, A J; Stauber, A J

    1982-06-01

    The McAllen and Brownsville Quadrangles, Texas, were evaluated to a depth of 1500 m to identify geologic environments and delineate areas favorable for uranium deposits. The environments were selected according to criteria established for the National Uranium Resource Evaluation program. Surface studies included investigations of uranium occurrences described in the literature, of locations of aerial radiometric anomalies, of surface exposures, and of locations of anomalous hydrogeochemical and stream-sediment reconnaissance data and collation of information on uranium exploration. Subsurface evaluation of selected geologic units was accomplished by using electric and gamma-ray well logs to construct maps and construct maps and cross sections. In the McAllen Quadrangle, an environment favorable for Texas roll-type sandstone uranium deposits is identified in 36 areas in the Goliad, Fleming-Oakville, Catahoula-Frio, and Whitsett Formations. All other units in both quadrangles are considered unfavorable.

  13. Aeromagnetic data processing and application in the evaluation of uranium resource potential in China

    International Nuclear Information System (INIS)

    The article introduces the main methods to deduce geological structures with aeromagnetic data, and summarizes the prediction elements of aeromagnetic characteristics for granite, volcanic, carbonaceous-siliceous-argillaceous rock and sandstone type uranium deposits. By analysing the relationship of aeromagnetic deduced geological structures and uranium mineralization, the prediction model of combined factors was summarized for each type uranium deposit. A case study in Taoshan-Zhuguang mineralization belt shows that the fault, plutons and volcanic structures deduced from areomagnetic information can judge the favorable mineralization environment and ore control structure. Therefore, the process and application of aeromagnetic data can play an important role in the evaluation of uranium resource potential and uranium exploration. (authors)

  14. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Republic of Burundi. Draft

    International Nuclear Information System (INIS)

    The basic objective of the International Uranium Resources Evaluation project lUREP is to 'Review the present body of knowledge pertinent to the existence of uranium resources, to review and evaluate the potential for the discovery of additional uranium resources and to suggest new exploration efforts which might be carried out in promising areas in collaboration with the countries concerned'. Therefore, the scope of the IUREP orientation phase Mission to Burundi was to review all data on past exploration in Burundi, to develop a better understanding of the uranium potential of the country, to make an estimate of the speculative resources of the country, to make recommendation as appropriate on the best methods or techniques for evaluating the resources in the favourable areas and for estimating possible costs as well, to compile a report which could be immediately available to the Burundian authorities. This mission gives a general introduction, a geological review of Burundi, information on non-uranium mining in Burundi, the history of uranium exploration, occurrences of uranium IUREP mission field reconnaissance, favourable areas for speculative potential, the uranium resources position and recommendations for future exploration. Conclusions are the following. The IUREP Orientation -phase mission to Burundi believes that the Speculative Resources of that country fall between 300 and 4100 tons uranium oxide but a less speculative appraisal is more likely between 0 and 1000 tons. There has been no uranium production and no official estimates of Uranium Resources in Burundi. Past exploration mainly dating from 1969 onwards and led the UNDP Mineral project has indicated a limited number of uranium occurrences and anomalies. The speculative uranium resources are thought to be possibly associated with potential unconformity related vein-like deposits of the Lower Burundian. Other speculative uranium resources could be associated with granitic or peribatholitic

  15. International symposium on uranium raw material for the nuclear fuel cycle: Exploration, mining, production, supply and demand, economics and environmental issues (URAM-2009). Book of abstracts

    International Nuclear Information System (INIS)

    The International Symposium on Uranium Raw Material for the Nuclear Fuel Cycle: Exploration, Mining, Production, Supply and Demand, Economics and Environmental Issues (URAM-2009) addressed all aspects of the uranium fuel cycle, from the availability of raw materials to the long-term sustainability of nuclear power. The revival of the uranium industry in recent years has caused a dramatic increase in uranium exploration and mining activities in several countries. URAM-2009 was intended to bring together scientists, exploration and mining geologists, engineers, operators, regulators and fuel cycle specialists to exchange information and discuss updated research and current issues in uranium geology and deposits, exploration, mining and processing, production economics, and environmental and legal issues. Contributed papers covered uranium markets and economics (including supply and demand); social licensing in the uranium production cycle; uranium exploration (including uranium geology and deposits); uranium mining and processing; environmental and regulatory issues; human resources development. There was a poster session throughout the symposium, as well as an exhibition of topical photographs. A workshop on recent developments in Technical Cooperation Projects relevant to the Uranium Production Cycle area was also organized. On the last day of the symposium, there was an experts' Panel Discussion. The presentations and discussions at URAM-2009 (a) led to a better understanding of the adequacy of uranium sources (both primary and secondary) to meet future demand, (b) provided information on new exploration concepts, knowledge and technologies that will potentially lead to the discovery and development of new uranium resources, (c) described new production technology having the potential to more efficiently and economically exploit new uranium resources; (d) documented the environmental compatibility of uranium production and the overall effectiveness of the final

  16. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Ghana

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) Mission to Ghana. The IUREP Orientation Phase Mission to Ghana estimates that the Speculative Resources of that country fall within the range of 15 000 to 40 000 tonnes of uranium. The majority of this potential is expected to be located in the Proterozoic Panafrican Mobile Belt (up to 17 000 tonnes uranium) and the Paleozoic Obosum Beds of the Voltaian basin (up to 15 000 tonnes uranium), the remainder being associated with various other geological environments. The mission recommends that over a period of three (3) years approximately U.S. $5 million) would be spent on exploration in Ghana. A major part of this (U.S $2 million) would be spent on an airborne spectrometer survey over the Voltaian basin (Obosum beds), much of the remainder being spent on ground surveys, trenching and percussion drilling.

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Malaysia

    International Nuclear Information System (INIS)

    Malaysia is a country of 330,000 square kilometers and a population of 11.9 million. The country is divided into two parts 640 kilometers apart. West Malaysia consists of the Malay Peninsula, and East Malaysia of the provinces of Sarawak and Sabah, formerly North Borneo. The country is the world's leading producer of tin and rubber. Geologic descriptions in detail are difficult to find although maps are available. Uranium exploration, chiefly by the Malaysian Geological Survey, has been carried out without discovery of commercial quantities. Based on possible recovery of uranium from deeply weathered granites on the Malay Peninsula, and possible discoveries in East Malaysia, a uranium potential of 1,000 to 10,000 tonnes U (category 2) is assigned.

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Brunei

    International Nuclear Information System (INIS)

    Brunei is a very small country consisting of only 5,800 sq km, and with only 150,000 people. Its main mineral products are crude oil and natural gas. It is hot and humid throughout the year being located only 4 degrees north of the equator on the island of Borneo. The sultanate of Brunei contains very thick sediments, some of which probably have the characteristics of a good uranium host rock for sandstone type deposits, but tacking a classic source, the uranium potential is minimal. Potential for other types of uranium deposits is likewise considered minimal. Therefore Brunei is assigned a potential in category 1 (less than 1000 tonnes U). (author)

  1. Sustainability of uranium mining and milling: toward quantifying resources and eco-efficiency.

    Science.gov (United States)

    Mudd, Gavin M; Diesendorf, Mark

    2008-04-01

    The mining of uranium has long been a controversial public issue, and a renewed debate has emerged on the potential for nuclear power to help mitigate against climate change. The central thesis of pro-nuclear advocates is the lower carbon intensity of nuclear energy compared to fossil fuels, although there remains very little detailed analysis of the true carbon costs of nuclear energy. In this paper, we compile and analyze a range of data on uranium mining and milling, including uranium resources as well as sustainability metrics such as energy and water consumption and carbon emissions with respect to uranium production-arguably the first time for modern projects. The extent of economically recoverable uranium resources is clearly linked to exploration, technology, and economics but also inextricably to environmental costs such as energy/water/chemicals consumption, greenhouse gas emissions, and social issues. Overall, the data clearly show the sensitivity of sustainability assessments to the ore grade of the uranium deposit being mined and that significant gaps remain in complete sustainability reporting and accounting. This paper is a case study of the energy, water, and carbon costs of uranium mining and milling within the context of the nuclear energy chain. PMID:18505007

  2. Recovery of uranium and thorium from secondary resources

    International Nuclear Information System (INIS)

    In the present paper an effort has been made to briefly describe first the effort that has been made at Rare Earths Division (RED), Alwaye, and Orissa Sands Complex (OSCOM) of IREL to recover nuclear grade ADU from uranium bearing monazite (0.35% U3O8) and other sources like thorium hydroxide (0.6% U3O8) and uranium fluoride concentrate (40%U). All these processes developed have similarity in the sense that they involve solvent extraction technology with novel combination of three different reagents falling in the category of acidic (PC88A) basic (ALAMINE-336) and neutral (TBP) extractants. Extensive R and D work in collaboration with uranium extraction division of BARC and plant scale trials have been completed to standardize the processes with respect to choice of ligands, composition of extractants, scrubbing/stripping reagents, number of stages as well as organic to aqueous ratios. Tons of ADU meeting the stringent specification have been produced and supplied to BARC for making uranium metal fuel for research reactors of the centre. In the case of uranium recovery from dilute phosphoric acid, the present paper is confined to use of a synergistic combination of DEHPA and TBP rather than well proven DEHPA-TOPO mixture. The primary motivation for examining this synergistic combination is the indigenous availability of both the solvent components since the supply of TOPO from the international market is likely to be denied. Based on the results of R and D test carried out at BARC large scale trials of various dilute phosphoric acids using experimental rigs consisting of carbon column, heat exchanger, commercial sized single stage mixer-settler, and plate separator are in progress at RED and OSCOM. IREL is also at advanced stage of pre-project activities and commercial negotiation with a number of host fertiliser companies like PPL, FACT and SPIC generating and using large volume of uranium bearing dilute phosphoric acid

  3. Worldwide uranium resources and production capacity - The future of the industry

    International Nuclear Information System (INIS)

    The worldwide uranium resource base is distributed across a broad range of confidence levels and projected production costs. High confidence low-cost resources (RAR) are, however, not geographically well diversified, with up to 75% of the resources located in just four countries. Therefore, to minimize the risk of production being delayed by environmental opposition, exploration should be diversified to include additional areas where mining will likely be accepted. Though the total resource base is extensive, a large part of it requires additional exploration, development drilling and engineering studies to be elevated to the high confidence RAR classification. Exploration investment needs to be made available now to ensure that resources are adequate to satisfy future uranium demand. For this to happen, however, the uranium industry must be confident that the recent increase in the market price will be sustainable over a long enough time period for it to accept the risks inherent in uranium exploration. Among the known uranium deposits that have near-term development potential, relative few have projected production capacities in excess of 3 000 t U/year. Therefore, the industry may be facing the need to develop large numbers of relatively small projects with production capacities in the 400 to 1 000 t U/year range. This scenario could well over load government agencies responsible for project permitting and licensing, potentially leading to delays in the start of production for lack of required permits

  5. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Somalia

    International Nuclear Information System (INIS)

    A full report has been compiled describing the findings of the International Uranium Resources Evaluation Project (IUREP) Orientation Phase Mission to Somalia. The Mission suggests that in addition to the reasonably assured resources (RAR) of 5 000 t uranium and estimated additional resources (EAR) of 11 000 t uranium in calcrete deposits, the speculative resources (SR) could be within the wide range of 0 - 150 000 t uranium. The majority of these speculative resources are related to sandstone and calcrete deposits. The potential for magmatic hydrothermal deposits is relatively small. The Mission recommends an exploration programme of about US$ 22 000 000 to test the uranium potential of the country which is thought to be excellent. The Mission also suggests a reorganization of the Somalia Geological Survey in order to improve its efficiency. Recommended methods include geological mapping, Landsat imagery interpretation, airborne and ground scintillometer surveys, and geochemistry. Follow-up radiometric surveys, exploration geophysics, mineralogical studies, trenching and drilling are proposed in favourable areas. (author)

  9. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Lebanon

    International Nuclear Information System (INIS)

    Geologically speaking, Lebanon is a young country since the oldest rocks are of Upper Jurassic age. Two volcanic periods are included in the more recent rocks. The country is intersected by numerous faults mainly striking NNE but also including numerous small transverse faults. No prospecting for nuclear raw materials has been recorded and there is no known activity at the present time. Lebanon has no national geological organization to support uranium prospecting. From the geological standpoint, possibilities of occurrences of nuclear minerals in Lebanon are poor and the Speculative Potential is placed in the less than 1000 tonnes uranium category. (author)

  11. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Vietnam

    International Nuclear Information System (INIS)

    The Chaine Annamatique represents the last of the three orogenic episodes that shook Indochina and forms most of Vietnam's boundary with Laos, In south Vietnam the mountains which have a north-south trend are formed of granites, gneisses and mica schists and are inseparable from the anti-hercynian formations. Iron ore, gold, lead, copper, tin, wolfraun, bismuth and molybdenium minerals are found. Plans had been made in 1960 to prospect for uranium but no information is available on whether that work was ever done. The only evidence of occurrences of nuclear raw materials is that titaniferous sands occur in several coastal regions and that uranium was once listed as having been produced in Forth Vietnam. Although the geology of Vietnam is not very conducive to the formation and preservation of uranium deposits it is possible that because of the granite terrain and presence of other metalliferous minerals, the Speculative Potential should be stated as in category 2 i.e. from 1,000 to 10,000 tonnes uranium.

  14. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Spain

    International Nuclear Information System (INIS)

    Spain, with an area of 504 748 km''2, occupies a large part of the Iberian Peninsula. At present the country appears to have about 6300 t of reasonably assured uranium reserves and 8500 t of additional estimated reserves (all at less than $30/lb of U3O8). Spain has devoted some $33 million to prospecting for uranium since the beginning of such work. Most of the reasonably assured reserves are located in ores impregnating Cambrian schists intersected by Hercynian granites (of so-called 'Iberian type'); a small amount, however, is found in veins in Hercynian granites of the Spanish Meseta. The additional estimated reserves are situated in the peripheral post-Hercynian continental basins of the Meseta. Apart from these classical ores, sub-ores have been identified in Silurian quartzites with low concentrations of uranium associated with refractory minerals, totalling more than 200,000 t of U (at concentrations of a few hundred ppm); there are likewise uranium-bearing Oligocene lignites in the Ebro Basin with some 140,000 t of U. These facts, and also the very wide distribution of uranium in space and time (from the Cambrian to the Miocene!) and the country's favourable geological characteristics, suggest that Spain ought in fact to have large reserves of uranium, a conclusion unfortunately belied by the paucity of the economic reserves identified so far. Two things must be borne in mind, however; firstly, Spain's financial outlay for uranium prospecting up till now represents only a quarter of what has been invested in France, for example, and, secondly, the nature of the mineralised bodies in Spain makes exploration difficult. In conclusion it seems that prospecting both of the Iberian-type deposits in the Meseta region and of the deposits associated with detrital sediments in the peripheral continental basins - especially blind mineralized bodies - should hold out excellent prospects for Spain. Consequently we propose that Spain should be placed at least in category

  15. Economy of uranium resources in a three-component reactor fleet with mixed thorium/uranium fuel cycles

    International Nuclear Information System (INIS)

    The potential for minimizing uranium consumption by using a reactor fleet with three different components and mixed thorium/uranium cycles has been investigated with a view to making nuclear power a more sustainable and cleaner means of generating energy. Mass flows of fissile material have been calculated from burnup simulations at the core-equivalent assembly level for each of the three components of the proposed reactor fleet: plutonium extracted from the spent fuel of a standard pressurised water reactor (first component) is converted to 233U in an advanced boiling water reactor (second component) to feed a deficit of multi-recycled 233U needed for the Th/233U fuel of the light/heavy water reactor (third component) which has a high breeding ratio. Although the proposed fleet cannot breed its own fuel, we show that it offers the possibility for substantial economy of uranium resources without the need to resort to innovative (and costly) reactor designs. A very high fleet breeding ratio is achieved by using only currently existing water-based reactor technology and we show that such three-component systems will become economically competitive if the uranium price becomes sufficiently high (> 300 $/kg). Another major advantage of such systems is a corresponding substantial decrease in production of minor actinide waste. (authors)

    For nuclear energy to remain sustainable in the United States, economically viable sources of uranium beyond terrestrial ores must be developed. The goal of this program is to develop advanced adsorbents that can extract uranium from seawater at twice the capacity of the best adsorbent developed by researchers at the Japan Atomic Energy Agency (JAEA), 1.5 mg U/g adsorbent. A multidisciplinary team from Oak Ridge National Laboratory, Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory, and the University of Texas at Austin was assembled to address this challenging problem. Polymeric adsorbents, based on the radiation grafting of acrylonitrile and methacrylic acid onto high surface-area polyethylene fibers followed by conversion of the nitriles to amidoximes, have been developed. These poly(acrylamidoxime-co-methacrylic acid) fibers showed uranium adsorption capacities for the extraction of uranium from seawater that exceed 3 mg U/g adsorbent in testing at the Pacific Northwest National Laboratory Marine Sciences Laboratory. The essence of this novel technology lies in the unique high surface-area trunk material that considerably increases the grafting yield of functional groups without compromising its mechanical properties. This technology received an R&D100 Award in 2012. In addition, high surface area nanomaterial adsorbents are under development with the goal of increasing uranium adsorption capacity by taking advantage of the high surface areas and tunable porosity of carbon-based nanomaterials. Simultaneously, de novo structure-based computational design methods are being used to design more selective and stable ligands and the most promising candidates are being synthesized, tested and evaluated for incorporation onto a support matrix. Fundamental thermodynamic and kinetic studies are being carried out to improve the adsorption efficiency, the selectivity of uranium over other metals, and the stability of the adsorbents.

    1976-08-01

    During the summer of 1975, 464 water samples from 149 locations in South Park, Colorado, were taken for the Los Alamos Scientific Laboratory in order to test the field sampling and analytical methodologies proposed for the NURE Hydrogeochemical and Stream Sediment Reconnaissance for uranium in the Rocky Mountain states and Alaska. The study showed, in the South Park area, that the analytical results do not vary significantly between samples which were untreated, filtered and acidified, filtered only, or acidified only. Furthermore, the analytical methods of fluorometry and delayed-neutron counting, as developed at the LASL for the reconnaissance work, provide fast, adequately precise, and complementary procedures for analyzing a broad range of uranium in natural waters. The data generated using this methodology does appear to identify uraniferous areas, and when applied using sound geochemical, geological, and hydrological principles, should prove a valuable tool in reconnaissance surveying to delineate new districts or areas of interest for uranium exploration.

    International Nuclear Information System (INIS)

    A report has recently been made public which describes the findings of the International Uranium Resources Evaluation Project (IUREP) Mission to Madagascar. The IUREP Orientation Phase Mission to Madagascar estimates the Speculative Resources of that country to be within the wide range of 4 000 to 38 000 tonnes uranium. Such resources could lie in areas with known occurrences (uranothorianite, Ft. Dauphin up to 5 000 t U, i.e. 'pegmatoids'; uranocircite, Antsirabe up to 3 000 t U in Neogene sediments; carnotiteautonite, Karoo area up to 30 000 t U in sandstones and in areas with as yet untested environments (e.g. related to unconformities and calcretes). Modifications to existing uranium exploration programmes are suggested and policy alternatives reviewed. No specific budget is proposed. (author)

    International Nuclear Information System (INIS)

    Quality of water resources are one of the vital components for industrial, agricultural and economical development as well as for security issue. The aim of this study is to evaluate the levels of uranium in the Egyptian water resources used for drinking purposes. Fifty-seven water samples representing Egyptian water resources for drinking water (unpurified, purified, tap and ground) were collected. Sensitive and rapid destructive laser fluorimetry technique was used for uranium determination. The results showed that the level of uranium in most of the collected samples was below than the safe limit recommended by the international organizations. The average annual equivalent dose due to the consumption of water ranged from 0.1 μSv/y to 2.0 μSv/y which is lower than the international recommendation

    International Nuclear Information System (INIS)

    The basic objective of IUREP is to 'review the present body of knowledge pertinent to the existence of uranium resources, to review and evaluate the potential for discovery of additional uranium resources, and to suggest new exploration efforts which might be carried out in promising new areas in collaboration with the countries concerned'. Following the initial bibliographic study, which formed Phase I of IUREP, it was envisaged that a further assessment in co-operation with the country in question would lead to a better delineation of areas of high potential and a more reliable estimate as to the degree of favourability for the discovery of additional uranium resources. It was planned that such work would be accomplished through field missions to the country and that these field missions and the resulting report would constitute the IUREP Orientation Phase. The purpose of the Orientation Mission to Colombia was (i) to develop a better understanding of the uranium potential of the country, (ii) to delineate areas favourable for the discovery of speculative uranium resources, (iii) to make recommendations, as appropriate, on the best methods for evaluating the favourable areas, operating procedures and estimated possible costs, (iv) to develop the logistical data required to carry out any possible further work, and (v) to compile a report that would be immediately available to the Colombian authorities. Uranium exploration in Colombia is of very recent date, with the majority of activities getting under way only after 1970. In spite of the limited work that has been done, however, over 1300 radioactive anomalies have been recorded. The total number of uranium mineral occurrences resulting from follow-up work is still very small, and some are unusual in world terms. Topographic and geographic conditions in Colombia make geological and exploration work very difficult and costly, especially in the Cordilleras and the Interior Zone (Llanos Orientales).

  2. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Burma

    International Nuclear Information System (INIS)

    There is no information on production of nuclear raw materials in Burma, although there are some uranium occurrences. Hunting Geophysics Ltd has done some aerial prospecting work in the area of Victoria Point in Southern Burma. All the data collected has been plotted on several maps and issued to various Burmese organizations, with a complete report. The follow-up ground exploration was done by a prospecting party headed by Dr Gjelsvik. The Hunting Geophysics' and Dr Gjelsvik reports are not available in the IAEA. The Raw Materials Division in the Union of Burma Atomic Energy Center commenced operations in 1955. The area of Mogok was selected by U Soo Win, the head of the Division, as most favourable for uranium exploration. The region is mountainous, with heavy forest cover. A ground gamma-ray survey was carried out in Mogok Mineral Belt by two geologists accompanied by two assistants, at a spacing of one km. This work showed monazite in all streams over an area of about 150 sq km and has given a detailed studies led to the discovery of some uraninite and pitchblende in the overburden of an old lode. Based, on these first discoveries the Government of Burma requested assistance from the IAEA and an expert was sent there for a period of one year. His field work was mainly limited in the Mogok Mineral Belt, however some reconnaissance field trips were made in other parts of the country. Dr D L Searle concluded that the Mogok area represents a zone of high temperature mineralization but a lower temperature form of uranium mineralization may have developed along the outer edges of the principal high grade zone. He recommended that the area between the Mogok scarp and the Shweli River be systematically traversed. Uranium bearing minerals in Burma are the following: monazite bearing beach sands near Amherst, Tenasserim; monazite placers from near Momeik, Northern Shan States; uraninte crystals from the gem-gravels around Mogok; a radioactive anomaly in syenite at

    International Nuclear Information System (INIS)

    Chile has an area of 740,760 square kilometers. The capital is Santiago. The country is 4,183 km. long and ranges from 22.5 to about 354 km. in width. Its chief topographic features para]lei each other - the Coastal Range, Andes Mountains and Central Valley. The Coastal Range rises to 2,130 meters in the north, but averages from 610 to 700 meters high generally. The range plunges into the Pacific Ocean far south of Valparaiso and reappears in the southern archipelagic islands. The Andes extend along nearly the entire length of Chile and contain 100 volcanoes. Andean peaks range mostly from 3,000 to 6,700 meters in elevation. In southern Chile the Andes are lower, and contain about a dozen major lakes. The mountains disappear in Chilean Patagonia, but reappear at Cape Horn. The Central Valley lies between the Coastal Range and the Andes, being best defined in the midland region as a 64 to 72 km sloping plain. It is the Chilean heartland with three-quarters of the country's population. Salt basins are found over much of northern Chile in the very arid desert, while the region south of the Gulf of Reloncavi consists of unpopulated islands, fjords, channels and heavily forested mountains. The Strait of Magellan, the Tierra del Fuego archipelago and a flat grassland area make up the extreme southern end of the country. Much of Chile is subject to flash floods, earthquakes, volcanic eruptions, landslides and avalanches. In September 1976 the Comision Chilena de Energia Nuclear (CCEN) was given exclusive rights to negotiate contracts with private companies for the exploration, development and mining of uranium and other radioactive minerals. The new law provides the CCEN with considerable flexibility in the terms of the contracts. Pre-964 owners of uranium deposits may reach agreements with foreign companies to mine the uranium, but since 1964 all uranium has belonged to the state. Uranium produced in the country can only be exported after Chile's needs have been met. The

  4. Exhaustible resources and economic growth: the case of uranium mining in Saskatchewan

    International Nuclear Information System (INIS)

    This study examines the effect of a booming natural resource sector on regional economic growth, with particular attention to the impact of regional government policy on mineral rent taxation and the allocation of resource revenues. The author's approach is first to document the relevant theory and then to apply it to the case of the uranium industry in Saskatchewan. Governments often hold the view that a significant portion of resource rents flowing from the boom should be appropriated by the public sector. The usual arguments of efficiency and equity are explained, as is their applicability to uranium in Saskatchewan. The model is extended to include provincial tax and expenditure policies. Chapter 2 concentrates on mineral taxes and examines their various effects on the behaviour of firms with respect to exploration and extraction. The theory about the effects of mineral taxes on exploration and extraction is reviewed and is subsequently used to anticipate the effect of taxes on uranium mining. The Saskatchewan Uranium Royalty is explicitly considered in a quantitative model to analyse the effect on the rate of extraction on the Key Lake Mine. It is agreed that taxes collected by the Saskatchewan government are corrective in nature in that they lower the rate of extraction and make up for certain market failures and improve efficiency of resource use. It is not accepted, however, that the allocation of these taxes contributes to economic efficiency. Plentiful low cost uranium reserves are predicted but government policy is likely to limit rapid expansion. Weighing these factors and the world uranium market, uranium production forecasts are derived and an estimate is made of the impact of the industry on economic growth in Saskatchewan. The contribution to Gross Domestic Provincial Product in 2000 could be as high as 10% of the 1980 GDPP level and the contribution to employment as high as 9% of 1980 nonagricultural employment. The reader is cautioned that the

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Turkey. The IUREP Orientation Phase mission to Turkey estimates that the Speculative Resources of that country fall within the range of 21 000 to 55 000 tonnes of uranium. This potential is expected to lie in areas of Neogene and possibly other Tertiary sediments, in particular in the areas of the Menderes Massif and Central Anatolia. The mission describes a proposed exploration programme with expenditures over a five year period of between $80 million and $110 million, with nearly half of the amount being spent on drilling.

    International Nuclear Information System (INIS)

    Finland covers an area of 337,000 skm. One third of the country lies north of the northern polar circle. 31,613 skm are covered by lakes. 71% of the landscape are covered by coniferous -wood. Climatlcal conditions are continental. The topography of the country is gently rolling with highest elevations of 300 m in the northern part. The most interesting geological units for uranium are Karelian, marginal meta-sediments, mainly quarzites and conglomerates but also schists. These schists are intruded by orogenlc plutonic rocks which are 1800-My-old. Potassium granites are common adjacent to the contact of the Pre-karelian basement (2500 My). In addition to these geological environment uranium and thorium minerals have been found in a large carbonatite in northern Finland, which is explored now

  9. International Uranium Resources Evaluation Project (IUREP) national favourability studies: El Salvador

    International Nuclear Information System (INIS)

    No information is available on past uranium exploration in El Salvador. The foetallogenic map of Central America (ICAITI, 1970) shows no uranium occurrences, and no descriptions of occurrences are available for this study. Information on current uranium exploration in El Salvador is not available. The 1922 mining code, as amended, covers all minerals, with special rules applicable to phosphates, petroleum and other hydrocarbons. The state owns all minerals, including phosphates, except for salt and other common materials. Mineral and surface rights are distinct. Both citizens and aliens may acquire mineral rights. There is a possibility of uranium potential in the clastic sediments containing interbedded volcanics, particularly where the latter are tuffaceous. These rocks occur chiefly in the north western part of the country and are of limited areal extent. The possibility of uranium occurrences associated with acid volcanics cannot be discounted, but it is difficult to evaluate rocks of this type for uranium with the present state of knowledge. Accordingly, potential resources are estimated at between 0 and 1,000 tonnes uranium

    2009-10-01

    Nuclear energy as one of clear energy sources takes important role in economic development in CHINA, and according to the national long term development strategy, many more nuclear powers will be built in next few years, so it is a great challenge for uranium resources exploration. Research and practice on mineral exploration demonstrates that utilizing the modern Earth Observe System (EOS) technology and developing new multi-source geological data mining methods are effective approaches to uranium deposits prospecting. Based on data mining and knowledge discovery technology, this paper uses multi-source geological data to character electromagnetic spectral, geophysical and spatial information of uranium mineralization factors, and provides the technical support for uranium prospecting integrating with field remote sensing geological survey. Multi-source geological data used in this paper include satellite hyperspectral image (Hyperion), high spatial resolution remote sensing data, uranium geological information, airborne radiometric data, aeromagnetic and gravity data, and related data mining methods have been developed, such as data fusion of optical data and Radarsat image, information integration of remote sensing and geophysical data, and so on. Based on above approaches, the multi-geoscience information of uranium mineralization factors including complex polystage rock mass, mineralization controlling faults and hydrothermal alterations have been identified, the metallogenic potential of uranium has been evaluated, and some predicting areas have been located.

  11. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Philippines

    International Nuclear Information System (INIS)

    Comparison between the geology of the Philippines and favourable geological environments for uranium in other parts of the world suggests that the Philippine geology is not likely to be favourable for the discovery of uranium. Previous work has been mainly of a reconnaissance type and orientated mainly to checking the existing mining areas for radioactivity. The only occurrence known at the present time is at Larap Mine in the Paracale District of Camarines Norte in Luzon. A magnetite iron ore body operated by Philippines Iron Mines Inc contained certain distinct beds, which, in addition to magnetite also contain copper, molybdenum and iron sulphides and uraninite. It is estimated that 200 short tons U3O8 is contained in 500,000 tons ore grading 0.04% U3O8 at Larap. A number of other largely untested but similar occurrences have also been identified in the Paracale District. A few small occurrences of uranium have recently been identified on the island of Samar. It is suggested that the Speculative Potential of the Philippines may be of the order of 1000 tonnes U3O8. (author)

    International Nuclear Information System (INIS)

    The Grand Duchy of Luxembourg is a tiny, roughly triangular, sovereign state situated in Western Europe and bordered by Belgium, the Federal Republic of Germany and Prance. Its total surface area is 998 sq. miles (2,586 sq. kilometres). Its situation in Europe has made it a natural crossroads, with its language, economic interests and ways of life reflecting its close association with its neighbours. It has, however, remained a separate, if not always autonomous, political unit since the tenth century. It is one of the nine member states of the European Economic Community. The country is made up of an elevated northern tableland and a southern lower plateau. The northern section comprises part of the Ardennes mountains which continue in south-east Belgium and form a plateau generally ranging between 1,000 and 2,000 feet. Iron ore mines are located near the French border. The southern section has an elevation of below 15,000 feet and comprises mainly heavily wooded good agricultural land. There has been virtually no work done; no uranium occurrences of significance are recorded. No specific exploration for uranium in Luxembourg is apparent at the present. There are no specific regulations relating to uranium exploration,which is covered by the rules relating to mineral exploration in general

  13. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Iran

    International Nuclear Information System (INIS)

    Iran is on the southern flank of the Alpine-Himalayan mountain system and has within its extensive boundaries rocks ranging from crystalline metamorphics and igneous rocks of Precambrian age to sediments of Tertiary - Pleistocene age, some of which could be considered as potentially favourable for uranium deposits. The search for uranium started about 1959 and in the following years some 40 radioactive anomalies and a small number of uranium occurrences were identified. In 1977 the Atomic Energy Organization of Iran greatly expanded its exploration activities and contracted for 895,000 line kilometres to be flown by three contractors in an aerial spectrometric survey designed to cover almost the two fifths of the whole country. The follow-up of this survey will continue for several years. Purely on the basis of its size (1,648,004 km2), its several favourable host rock areas, its location on the flank of the Alpine-Himalayan system and the relatively small amount of systematic exploration coverage completed to date the Speculative Potential could be placed in the 50,000 - 100,000 tonnes category.

  15. National uranium resource evaluation. Raton Quadrangle New Mexico and Colorado. Final report

    International Nuclear Information System (INIS)

    Using National Uranium Resource Evaluation criteria, the Raton Quadrangle (New Mexico and Colorado) contains one environment favorable for uranium deposits, the permeable arkosic sandstone members of the Pennsylvanian-Permian Sangre de Cristo Formation for either peneconcordant or roll-type deposits. The favorable parts of the Sangre de Cristo lie mostly in the subsurface in the Raton and Las Vegas Basins in the eastern part of the quadrangle. An area in the Costilla Peak Massif was investigated for uranium by determining geochemical anomalies in stream sediments and spring waters. Further work will be required to determine plutonic environment type. Environments unfavorable for uranium deposits include the Ogallala, Raton, and Vermejo Formations, the Trinidad Sandstone, the Pierre Shale, the Colorado Group, the Dakota Sandstone, the Morrison Formation, the Entrada and Glorieta Sandstones, Mississippian and Pennsylvanian rocks, quartz-pebble conglomerates, pegmatities, and Tertiary granitic stocks

  16. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Zambia

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Zambia. The IUREP Orientation Phase mission to Zambia estimates that the Speculative Resources of that country fall within the range of 33 000 and 100 000 tonnes uranium. The majority of these resources are believed to exist in the Karoo sediments. Other potentially favourable geological environments are the Precambrian Katanga sediments, as well as intrusive rocks of different chemical compositions and surficial duricrusts. Previous unofficial estimates of Zambia's Reasonably Assured Resources (RAR) and Estimated Additional Resources (EAR) are considered to be still valid: the total RAR amount to 6 000 tonnes uranium, located in Karoo (4 000 tonnes) and Katanga (2 000 tonnes) sediments, while the EAR are believed to total 4 000 tonnes being found only in Karoo sediments. The mission recommends that approximately US$ 40 million be spent on uranium exploration in Zambia over 10 years. The largest part of this expenditure would be for drilling, while the remainder should be spent on airborne and ground surveys, as well as on interpretative work on previous airborne data, Landsat imageries, etc. (author)

  17. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Republic of Korea

    International Nuclear Information System (INIS)

    The Republic of Korea, occupies the southern end of the Korean peninsula. It has a long history of mining and mineral production, and has an active and fairly well equipped Geological Survey. The country in general is quite highly mineralized with many minerals including uranium although there has been no uranium production from it yet. Uranium occurs in granites, schists, and in black carbonaceous shales. The Korean Geological survey has estimated that one ore body contains 650 tonnes U in 1,600,000 tons of ore at an average grade of 0.047 percent U3O8. Many recent reports also indicate very large resources of uranium in very low grade ranges. The uranium potential for the Republic of Korea is considered in Category 2 (1,000 - 10,000 tonnes U) in the normal IUREP context. However, a very large resource may exist in the very low grades in black shales of the country. This resource is considered as in category 6 (500,000 to 1,000,000 tonnes U). (author)

  18. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Morocco

    International Nuclear Information System (INIS)

    A report has recently been published on the findings of the mission to Morocco under the International Uranium Resources Evaluation Project (IUREP) Orientation Phase. The IUREP Orientation Phase Mission estimates that the speculative resources of Morocco range from 70 000 to 180 000 tonnes of uranium, half of which could be expected to occur in the Northern Provinces, which are relatively well explored, and the other half in the little explored Southern Provinces. In the north, speculative resources are fairly evenly distributed among the various types of deposit, in particular vein deposits (intragranitic and contact) linked with Hercynian and Precambrian blocks, the sandstone type deposits linked with Mesozoic strata and the volcanogenic deposits, especially of Precambrian age. The potential for large high-grade deposits, especially for those linked with unconformities and linear albitites, has been little investigated in Morocco and is chiefly thought to lie in the Precambrian in the Anti-Atlas and Southern Provinces. Here, the presence of acid volcanic rock reinforces the uranium potential, and there is also some potential for calcrete-related deposits. Phosphate-related uranium, to be recovered shortly, constitutes by far the largest reserves in Morocco, estimated at about 7 million tonnes of recoverable uranium. Recommendations have been made for further study of known occurrences and identification of new ones, such as unconformity and albitite-related deposits. (author)

  19. Uranium, resources, production and demand including other nuclear fuel cycle data

    International Nuclear Information System (INIS)

    The uranium reserves exploitable at a cost below 15 dollars/lb U3O8, are 210,000 tonnes. While present uranium production capacities amount to 26,000 tonnes uranium per year, plans have been announced which would increase this capacity to 44,000 tonnes by 1978. Given an appropriate economic climate, annual capacities of 60,000 tonnes and 87,000 tonnes could be attained by 1980 and 1985, respectively, based on presently known reserves. However, in order to maintain or increase such a capacity beyond 1985, substantial additional resources would have to be identified. Present annual demand for natural uranium amounts to 18,000 tonnes and is expected to establish itself at 50,000 tonnes by 1980 and double this figure by 1985. Influences to increase this demand in the medium term could come from shortages in other fuel cycle capacities, i.e. enrichment (higher tails assays) and reprocessing (no uranium and plutonium recycle). However, the analysis of the near term uranium supply and demand situation does not necessarily indicate a prolongation of the current tight uranium market. Concerning the longer term, the experts believe that the steep increase in uranium demand foreseen in the eighties, according to present reactor programmes, with doubling times of the order of 6 to 7 years, will pose formidable problems for the uranium industry. For example, in order to provide reserves sufficient to support the required production rates, annual additions to reserves must almost triple within the next 15 years. Efforts to expand world-wide exploration levels to meet this challenge would be facilitated if a co-ordinated approach were adopted by the nuclear industry as a whole

  20. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Colombia

    International Nuclear Information System (INIS)

    A full report has been released describing the findings of the International Uranium Resources Evaluation Project (IUREP) Orientation Phase Mission to Colombia. The Mission suggests that the speculative uranium resources of the country could be within the very wide range of 20 000 tonnes of 220 000 tonnes of uranium metal. The Mission finds that the area with the highest potential is the Llanos Orientales (Interior Zone), which has the potential of hosting quartz-pebble conglomerate deposits, Proterozoic unconformity-related deposits and sandstone deposits. The Mission recommends that approximately US$80 million should be expended in a phased ten-year exploration programme. It is likely that the majority of the funds will be needed for drilling, followed by ground surveys and airborne radiometry. It is the opinion of the Mission that the considerable funds required for the proposed programme could most suitably be raised by inviting national or foreign commercial organizations to participate under a shared production agreement.

  1. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Bolivia

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Bolivia. The IUREP Orientation Phase mission to Bolivia estimates that the Speculative Uranium Resources of that country fall within the range of 100 to 107 500 tonnes uranium. The majority of this potential is expected to be located in the Precambrian crystalline and sedimentary rocks of the southwestern part of the Central Brazilian Shield. Other potentially favourable geologic environments include Palaeozoic two mica granites and their metasedimentary hosts, Mesozoic granites and granodiorites as well as the intruded formations and finally Tertiary acid to intermediate volcanics. The mission recommends that approximately US$ 13 million be spent on exploration in Bolivia over a five-year period. The majority of this expenditure would be for airborne and surface exploration utilising geologic, magnetometric, radiometric, and geochemical methods and some pitting, trenching, tunneling and drilling to further evaluate the discovered occurrences.

  2. National Uranium Resource Evaluation. Bibliographic index of Grand Junction office uranium reports

    International Nuclear Information System (INIS)

    In October 1978, Mesa College entered into subcontract with Bendix Field Engineering Corporation (BFEC) to prepare a bibliographic index of the uranium raw materials reports issued by the Grand Junction Office of the US Department of Energy (DOE). Bendix, prime contractor to the Grand Junction Office, operates the Technical Library at the DOE facility. Since the early 1950s, approximately 2700 reports have been issued by the Grand Junction Office. These reports were the results of uranium investigations conducted by federal agencies and their subcontractors. The majority of the reports cover geology, mineralogy, and metallurgy of uranium and/or thorium. No single, complete list of these reports existed. The purpose of this subcontract was to compile a comprehensive index to these reports. The Mesa College geology faculty worked with the BFEC and DOE staffs to develop the format for the index. Undergraduate geology students from Mesa compiled a master record sheet for each report. All reports issued up to January 1, 1979 were included in the bibliography. The bibliography is in preliminary, unedited form. It is being open-filed at this time, on microfiche, to make the information available to the public on a timely basis. The bibliography is divided into a master record list arranged in alpha-numeric order by report identification number, with separate indices arranged by title, author, state and county, 10 x 20 NTMS quadrangle, key words, and exploration area

There is not now and never has been a mining industry except for quarrying of coral road metal. Geologically the coral islands, based on present geological thinking is not a favourable host or source of uranium, and is therefore assigned a zero potential. (author)

  8. International Uranium Resources Evaluation Project (IUREP) national favourability studies: The Netherlands

    International Nuclear Information System (INIS)

    The Netherlands is part of the lowlands of Western Europe formed by negative crustal movements that have been offset by sedimentation. This specific area stretching from western Belgium into north-western Germany forms part of an epicontinental area that has been relatively stable since the end of the Hercynian orogeny. In Holland the subsidence has generally been small through- out the Mesozonic and Cenozoic though interrupted by short periods of erosion and non-subsidence. Thus the general geology of the Netherlands is dominated by the fact that throughout the Tertiary and Quaternary what now comprises the Netherlands formed part of a subsiding basin. Most of the surface geology of the country is dominated by f luvio-glacial shallow marine and lacoustine deposits. Prospecting for radioactive minerals in the Netherlands has been very limited. Some work has been carried out by the Geological Survey and by private consultants but this was very preliminary. To-date no uranium reserves or resources have been identified in the Netherlands. One small uranium occurrence has been recorded in Zeeland near Walcheren where some small uranium concentrations were found in association with phosphatic nodules. Apart from very limited targets in the Cretaceous and small phosphatic uranium associations there are no apparent uranium exploration targets in the Netherlands. On this basis we would, at this time, place the uranium potential of the Netherlands in Group I of the IUREP classification

  9. Resource characterization for uranium mineralization in the Montrose 10 x 20 quadrangle, Colorado

    International Nuclear Information System (INIS)

    A data-classification scheme was developed to detect potential uranium mineralization in the Montrose 10 x 20 quadrangle, Colorado. The methodology developed is a rapid and efficient method of resource evaluation on a reconnaissance scale. The necessary techniques were developed and refined to digitize, integrate, and register various large geological, geochemical, and geophysical data sets for the Montrose quadrangle, Colorado, using a grid resolution of 1 km. All data sets for the Montrose quadrangle were registered to the Universal Transverse Mercator projection. The data sets include hydrogeochemical and stream sediment analyses for 23 elements, uranium-to-thorium ratios, airborne geophysical survey data, the locations of 90 uranium occurrences, and a geologic map (scale 1:250 000). Geochemical samples were collected from 3965 locations in the 19 200 km2 quadrangle; aerial data were collected on flight lines flown with 3 to 5 km spacings. These data sets were smoothed by universal kriging and interpolated to a 179 x 119 rectangular grid (each grid block is 1 km2). A mylar transparency of the geologic map was prepared and digitized. All possible combinations of three, for all data sets, were examined for general geologic correlations by utilizing a color microfilm output. Subsets of data were further examined for selected test areas. A classification scheme for uranium mineralization, based on selected test areas in the Cochetopa uranium district, is presented. Areas favorable for uranium mineralization, based on this scheme, were identified and are discussed

  10. Gravity data processing and research in potential evaluation of uranium resource in China

    International Nuclear Information System (INIS)

    Through data processing, anomaly extraction, geologic structure deduction from gravity in 39 uranium metallogenic zones and 29 prediction areas, the predicting factors such as tectonic units, faults, scope and depth of rocks, scope of basins and strata structure were provided for the evaluation of uranium resources potential. Gravity field features of uranium metallogenic environment were summarized for hydrothermal type uranium deposits (granite, volcanic and carbonate-siliceous-argillaceous type) as regional gravity transition from high to the low field or the region near the low field, and the key metallogenic factors as granite rocks and volcanic basins in the low gravity field. It was found that Large-scale sandstone type uranium mineralization basins are located in the high regional gravity field, provenance areas are in the low field, and the edge and inner uplift areas usually located in the high field of the residual gravity. Faults related to different type uranium mineralization occur as the gradient zones, boundaries, a string of bead anomalies and striped gravity anomalies in the gravity field. (authors)

  11. Antecedents of historical evolution of the uranium resources in the Cuyo region, between 1951 and 1968

    International Nuclear Information System (INIS)

    The present article pretends to summarize the initial stage of the development of national uranium resources - focusing the labor done by the Escuela Superior de Ingenieria en Combustible of the Universidad Nacional de Cuyo - between the years 1951 and 1955 - feeling that it is necessary to describe the situations that were originated during the development of the uranium's mineral investigation. This was started by the Escuela Superior de Ingenieria en Combustible of U.N. de Cuyo, which facilitated the connection with CNEA, that had been created in 1950. This leaded to the economical help from CNEA until 1955, for the realization and execution of the programmed works. The national antecedents are described, taking into account the existence of deposits in this country. The historical evolution of the exloration of uranium in Cuyo is divided in three periods, which are described in detail in this work. First and foremost, the period that goes from 1951 to 1955 (U.N. de Cuyo and CNEA); then, the period that goes from 1956 to 1961 (CNEA) where the achievements obtained determined the new modern structures done by the CNEA in order to continue with the development of the uranium resources of the country. After this, the period that goes from 1961 to 1968 (activities and successes of the West Delegation) is pointed out. Finally, the evolution of the factories of uranium mineral treatment, i n the period between 1952 and 1990, is also described in this article. (Author)

    International Nuclear Information System (INIS)

    The Federal Republic of Austria is situated in the southeastern part of Central Europe. The country covers a total area of 83.350 square kilometers, the population amounts to 7.5 million inhabitants. The geographical features of Austria are dominated by the E-W-trending chain of the Alps (approximately 60% of the country). The northeastern part of the country is formed by the nonalpine mountains and hills of the Bohemian Massif. There are a large depression, the basin of Vienna, as well as parts of the Pannonian basin in the eastern part. The main hydrographic features are characterized by the river Danube and its tributaries. With the exception of a small part in the west of the country, the drainage system of which is directed to the river Rhine, all other rivers are drained by the Danube. The elevations in the Alps reach heights of up to 3 800 m. Many of the E-W striking mountain chains are higher than 2000 to 2500 m. Several major N-S trending passes over the mountains are favourable for the transportation systems (railroads, motorroads) - The kind of land use in Austria is mainly determined by the character of the landscape which is made up of mountains and valleys as well as of depressions in the eastern part of the country. In the lowlands, good farmland is available. At lower and at medium elevations, forests and grassland predominate in the Alps. At higher elevations, the Alps are covered with grasslands; a great part of the rocks has no soil cover, another part is covered by perennial snow and ice.The presence of many uranium occurrences in the Permo-Triassic sediments justifies a detailed survey of these strata. Special studies on the lithology and the formation of uranium in these rocks have been made during the last few years. They should be evaluated to point out new favourable prospective areas. The potential of Uranium which is assumed to be found in Austria is 10,000 - 50,000 t U

  13. Sustainability of Water Cooled Reactors - Energy Balance for Low Grade Uranium Resources

    International Nuclear Information System (INIS)

    The opponents of nuclear power claim that as uranium resources get exhausted the energy needed to mine low grade uranium ore will be larger than the energy that can be obtained from fission in a nuclear power plant. This would result in loss of sustainability of nuclear power, with the negative energy balance expected within the next 40-60 years. Since the opponents state clearly that the ore containing less than 0.013% U3O8 cannot yield positive energy balance, the study of the Institute of Atomic Energy in Poland referenced three mines of decreasing ore grade: Ranger 0.234% U3O8, Rossing 0.028% U3O8 and Trekkopje 0.00126% U3O8, that is with ore grade below the postulated cut off value. The study considered total energy needs for uranium mining, including not only electricity needed for mining and milling, for water treatment and delivery, but also fuel for transportation and ore crushing, explosives for rock blasting, chemicals for uranium leaching and the energy needed for mine reclamation after completed exploitation. It has been shown that the energy estimates of nuclear opponents are wrong for Ranger mine and go off much further for the mines with lower uranium ore grades. The reasons for erroneous reasoning of nuclear opponents have been found. Their errors arise from treating the uranium ore deposits as if their layout and properties were the same as those of uranium ore mined in the US in the 70-ies. This results in an oversimplified formula, which yields large errors when the thickness of the overlayer is less than it was in the US. In addition the energy needs claimed for mine reclamation are much too high. The study showed that the energy needed for very low grade uranium ore mining and milling increases but the overall energy balance of the nuclear fuel cycle remains strongly positive. (author)

  14. National Uranium Resource Evaluation: Cortez quadrangle, Colorado and Utah

    International Nuclear Information System (INIS)

    Six stratigraphic units are recognized as favorable for the occurrence of uranium deposits that meet the minimum size and grade requirements of the U.S. Department of Energy in the Cortez 10 x 20 Quadrangle, Utah and Colorado. These units include the Jurassic Salt Wash, Recapture, and Brushy Basin Members of the Morrison Formation and the Entrada Sandstone, the Late Triassic Chinle Formation, and the Permian Cutler Formation. Four areas are judged favorable for the Morrison members which include the Slick Rock, Montezuma Canyon, Cottonwood Wash and Hatch districts. The criteria used to determine favorability include the presence of the following (1) fluvial sandstone beds deposited by low-energy streams; (2) actively moving major and minor structures such as the Paradox Basin and the many folds within it; (3) paleostream transport directions approximately perpendicular to the trend of many of the paleofolds; (4) presence of favorable gray lacustrine mudstone beds; and (5) known uranium occurrences associated with the favorable gray mudstones. Two areas of favorability are recognized for the Chinle Formation. These areas include the Abajo Mountain and Aneth-Ute Mountain areas. The criteria used to determine favorability include the sandstone-to-mudstone ratio for the Chinle Formation and the geographic distribution of the Petrified Forest Member of the Chinle Formation. Two favorable areas are recognized for the Cutler Formation. Both of these areas are along the northern border of the quadrangle between the Abajo Mountains and the Dolores River Canyon area. Two areas are judged favorable for the Entrada Sandstone. One area is in the northeast corner of the quadrangle in the Placerville district and the second is along the eastern border of the quadrangle on the southeast flank of the La Plata Mountains

  15. Orientation study of the Lake Sunapee area, New Hampshire. National Uranium Resource Evaluation Program

    International Nuclear Information System (INIS)

    An orientation study was conducted in the area of Lake Sunapee, New Hampshire, in preparation for a hydrogeochemical and stream sediment reconnaissance in glacial terrain. The study was carried out by the Savannah River Laboratory as part of the National Uranium Resource Evaluation (NURE). Ground water, lake water, stream water, lake sediment, and stream sediment samples were collected at 188 sites. The concentrations of uranium and other elements were determined by neutron activation analysis. This report is issued in draft form, without detailed technical and copy editing. This was done to make the report available to the public before the end of the NURE program

    International Nuclear Information System (INIS)

    The Gilbert and Ellice Islands occupy about 1200 square kilometers of islands scattered over nearly 7,000,000 square kilometers of the Pacific Ocean, All are coral islands except Ocean Island which is of volcanic origin and is a very important producer of phosphate rock. The geology of the Gilbert and Ellice Islands is not considered favourable for uranium disposition, but a small by-product resource in category one is assigned on the basis of the possibility that the phosphate deposits contain a small quantity of uranium.

  17. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Sudan. February-March 1981

    International Nuclear Information System (INIS)

    The IUREP Orientation Phase Mission to the Democratic Republic of the Sudan believes that the Speculative Resources of the country might fall between 20,000 and 40,000 tonnes uranium and more. This indicates that the Speculative Resources of the Sudan could be significantly higher than previously estimated (7,500 tonnes uranium) by the NEA/IAEA Steering Group on the Uranium Resources - IUREP Phase I. The Government is willing to consider valid exploration programmes presented by prospective partners as long as they serve the interests of both parties. Within the general six-year (1977/78-1982/83) plan for development of the country's mineral resources, the Ministry of Energy and Mining has set up certain priorities which it would like to see expeditiously implemented: uranium exploration and production stands high on the list of priorities. On the basis of very limited information on regional geology and on previous exploration which was available to the Mission, it is estimated that the greatest potential for the Speculative Resources of possible economic significance will prove to occur in the following geological environments of the Sudan (Red Sea Hills area is not included): precambrian basement complex, palaeozoic-mesozoic-tertiary sedimentary basins and the tertiary to recent calcretes. The IUREP Orientation Phase Mission believes that some 20 Million US$ (very rough estimate) will be needed to (1) check the validity of the basic geological concepts formulated on the uranium potential of the selected areas, (2) accumulate diagnostic geological, geophysical, geochemical data indicative of a true uranium potential there, (3) study the basement complex rocks and the sedimentary formations at least on a broad structural-stratigraphic reconnaissance basis (a tremendous amount of valuable water drilling data has accumulated over the last years for some of the selected sedimentary basins) and (4) determine the most appropriate investigation techniques to be utilized

  18. Mineral evaluation of part of the Gold Butte district, Clark County, Nevada. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    The mineral potential of part of the Gold Butte district, Clark County, Nevada, was investigated to supplement the evaluation of granitic rocks in the area as a probable geologic environment for uranium mineralization. This project is a part of the National Uranium Resource Evaluation (NURE) program conducted by Bendix Field Engineering Corporation for the US Department of Energy. A total of 41 stream-sediment samples and 149 rock samples were collected; the stream-sediment samples were analyzed chemically, and most f the rock samples were analyzed chemically and petrographically. The project area was restricted to Precambrian rocks, which comprise a metamorphic complex of early Proterozoic age, charnockitic rocks of early or middle Proterozoic age and ultramafic rocks and the Gold Butte Granite of middle Proterozoic age. Although the project area is not favorable for uranium deposits according to NURE criteria, an area of low resource potential for uranium, thorium, rare-earth elements and yttrium, and niobium-tantalum was assigned to the contact zone of the Gold Butte Granite. Pegmatites and aplites in the zone contain high concentrations of these elements. Two areas of moderate potential for gold and silver in quartz veins are within the project area; small-scale operations may recover these elements profitably. Titanium has a low-to-moderate resource potential, although the deposits are currently subeconomic. The titanium concentrations occur as titaniferous magnetite- and ilmenite-bearing placer sands. One small area has been assigned a low-to-moderate resource potential for vermiculite in altered ultramafic rocks. Tungsten has been assigned a low resource potential in two places within the project area; scheelite-bearing ultramafic bodies are small and scattered. Platinum-group metals and copper have no resource potential in the project area

  19. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Thailand

    International Nuclear Information System (INIS)

    The IURBP Orientation Phase Mission assesses the Speculative Uranium Resources in Thailand to be within the range of 1 500 to 38 500 tonnes U. Geological environments which are considered by the Mission to be favourable for uranium occurrences include the following: sandstones of Jurassic to Triassic age; Tertiary sedimentary basins (northern Thailand); Tertiary sedimentary basins (southern Thailand); associated with fluorite deposits; granitic rocks; black shales and graphitic slates of the Palaeozoic; associated with sedimentary phosphate deposits; and associated with monazite sands. Physical conditions in Thailand, including a wet tropical climate, dense forest growth and rugged terrain in some areas and relative inaccessibility, make exploration difficult and costly. There is currently no ready accessibility to detailed topographic and geological maps and other basic data. This lack of availability is a severe constraint to systematic exploration. The lack of skilled personnel experienced in uranium studies and the low level of technical support is a serious hindrance to exploration in Thailand. (author)

  1. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Pakistan

    International Nuclear Information System (INIS)

    In 1959 uranium was discovered in the Siwalik Sandstones to the west of Dera Ghazi Khan. Subsequent exploration by the Atomic Energy Minerals Centre of the Pakistan Atomic Energy Commission, latterly assisted by an IAEA/UNDP project identified some 50 radioactive anomalies or groups of anomalies, in a Siwalik area 120 miles long and 30 miles wide. Most exploration work was concentrated at one locality known as Baghal Chur where two paleostream channel controlled ore shoots were investigated. Uraninite and coffinite were the ore minerals in the non-oxidised zone and tyuyamunite in the oxidised zone. Approximately 300 short tons U3O8 have been indicated in the two ore shoots in ore grading 0.12% U3O8 and a further 400 short tons are inferred in the extensions. Within Pakistan there are seven other extensive Siwalik areas, in at least one of which other radioactive anomalies have been found but which for all practical purposes remain virtually unexplored. On the basis of the areas involved and the comparison with the Dera Ghazi Khan area a Speculative Potential of 10,000 tonnes U3O8 is estimated for Pakistan. (author)

  2. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Greece

    International Nuclear Information System (INIS)

    Greece, with an area of 131,944 km2, has been actively explored since 1971 under a programme of co-operation with UNDP and IAEA on which close to US $1 million have been spent so far. The programme is focused on the Rhodope Precambrian massif, which is the most attractive structural unit from the geological point of view. The indications available at present, and which have been known for a long time, are also to be found in this unit. They are associated either with Tertiary continental volcanism or with detritic sediments in basins covering this massif. So far there is no evidence of their being of any economic value. The paucity of data available on the basement of the Rhodope precludes any prediction as to the possibility of its containing Pre-cambrian uranium mineralizations. One might perhaps think in terms of mineralizations of the alaskite or alkaline complex type, or also of vein-type deposits. But it is primarily in the deposits associated with tertiary trachy-rhyolitic volcanism that we have most confidence, especially in the Rhodope massif and the Vardar region but possibly elsewhere in the Hellenides as well. All things considered, we place Greece in Group 2 of the IUREP classification. (author)

  4. Bioremediation/Biorecovery of uranium from aquatic resource/waste: the Cyano-Deino story

    International Nuclear Information System (INIS)

    Terrestrial sources of uranium are getting depleted fast and may be exhausted in the next few decades. This has triggered a search for alternate or secondary resources for this precious metal. Nearly 4.5 billion tons of uranium on our planet resides in seawater, albeit at very low concentrations of 3 ppb. Recovering uranium from such low concentrations is a major challenge. Two marine cyanobacteria, the unicellular Synechococcus elongatus and the filamentous Anabaena torulosa, were found to be capable of rapidly sequestering uranyl carbonate (the predominant uranyl species at the sea-water pH of 7.8) from aqueous solutions, including simulated sea-water. While Synechococcus strain adsorbed the metal as carbonato complexes on cell surface ligands, A. torulosa trapped it in novel surface-associated polyphosphate bodies. The uranium binding potential of cyanobacterial biomass was comparable to, if not better than, the currently in use polyamidoxime resin. The bound uranium could be desorbed easily and the biomass reused a few times. The method has eminently higher application potential in uranium-contaminated terrestrial waters, where the metal concentration is several times higher. Low concentrations (<1 to few mM) of uranium are also found in acidic/alkaline nuclear waste and arise from metal extraction or during reprocessing of fuel. Removal of uranium from such solutions is very desirable for safer disposal of such waste. Biological agents to be employed in such situations also need to be tolerant to and stable in high radiation environments, unless dead cells can be used. To address such bioremediation, the extremely radio-resistant microbe Deinococcus radiodurans was genetically engineered to express either a non-specific acid phosphatase PhoN or a highly active novel alkaline phosphatase PhoK. Apart from the need for high expression of desired protein, such engineering is also fraught with problems of stability, localization and activity of the expressed

  5. Overview of the National Uranium Resource Evaluation Hydrogeochemical and Stream Sediment Reconnaissance Program

    International Nuclear Information System (INIS)

    A Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) for uranium is currently being conducted throughout the conterminous United States and Alaska. The HSSR is part of the National Uranium Resource Evaluation sponsored by the US Department of Energy. This ambitious geochemical reconnaissance program is conducted by four Department of Energy laboratories: Los Alamos Scientific Laboratory, Lawrence Livermore Laboratory, Oak Ridge Gaseous Diffusion Plant, and Savannah River Laboratory. The program is based on an extensive review of world literature, reconnaissance work done in other countries, and pilot studies conducted by each laboratory. Sample-collection methods and sample density are determined to optimize the probability of detecting potential uranium mineralization. To achieve this aim, each laboratory has developed independent standardized field collection procedures that are designed for its section of the country. Field parameters such as pH, conductivity, climate, geography, and geology are recorded at each site. Most areas are sampled at densities of one sample site per 10 to 23 km2. The HSSR program has helped to improve existing hydrogeochemical reconnaissance exploration techniques. In addition to providing industry with data that may help to identify potential uranium districts and to extend known uranium provinces, the HSSR also provides multielement analytical data that can be used in water quality, soil, sediment, environmental, and base-metal exploration studies

  8. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Brazil

    International Nuclear Information System (INIS)

    Brazil occupies an area of about 8.5 million square kilometers -- almost half of the South American continent. The dominant geographic feature is the Amazon basin. The Amazon River and its more than 200 tributaries drain about 60 percent of the country. The basin is a vast tropical rain forest, whereas the remainder of Brazil is made up predominantly of highlands. The Central Highlands, which extends into the Amazon basin, occupies nearly all of southern Brazil and includes major mountain chains such as the Serra do Mar, Serra da Mantiqueira, and Serra do Espinhago. The Guiana Highlands fringe the northern Amazon basin and extend into Venezuela, Guyana, Surinam, and French Guiana. Lowland areas other than the Amazon basin are found in western Mato Grosso, and along the Atlantic coast from French Guiana to Uruguay. The geology of Brazil is dominated structurally and areally by three major shields composed of crystalline rocks of Archean and Proterozoic age. Collectively they comprise the Brazilian complex which is probably the largest Precambrian outcrop in the world. The complex is made up of gneisses, granites, mica schists, quartzites, dolomites, skarns, diorites, itabirites and gabbros, many of which are deeply metamorphosed. Faults, quartz veins, and dikes are common. Recurrent granitization has occurred from the Precambrian to Late Tertiary. The area of Brazil is large and its geology is favorable, in places, for every known type of uranium deposit. This is not reflected in the amount of 'known' and 'inferred' reserves -- slightly more than 21,000 tons. Rather, it is an indication of the small amount of exploration done, taking into account the large area to be covered. The speculative potential can only be guessed. It is guessed to be 500,000 tons

  9. Lung cancer in uranium miners: A tissue resource and pilot study. Final performance report

    International Nuclear Information System (INIS)

    This project incorporates two related research projects directed toward understanding respiratory carcinogenesis in radon-exposed former uranium miners. The first project involved a continuation of the tissue resource of lung cancer cases from former underground uranium miners and comparison cases from non-miners. The second project was a pilot study for a proposed longitudinal study of respiratory carcinogenesis in former uranium miners. The objectives including facilitating the investigation of molecular changes in radon exposed lung cancer cases, developing methods for prospectively studying clinical, cytologic, cytogenetic, and molecular changes in the multi-event process of respiratory carcinogenesis, and assessing the feasibility of recruiting former uranium miners into a longitudinal study that collected multiple biological specimens. A pilot study was conducted to determine whether blood collection, induced sputum, bronchial brushing, washings, and mucosal biopsies from participants at two of the hospitals could be included efficiently. A questionnaire was developed for the extended study and all protocols for specimen collection and tissue handling were completed. Resource utilization is in progress at ITRI and the methods have been developed to study molecular and cellular changes in exfoliated cells contained in sputum as well as susceptibility factors

  11. Uranium resources and production of nuclear fuel material in the world

    International Nuclear Information System (INIS)

    Data are summed up relating to uranium resources, the technology of nuclear fuel manufacture, the prices of U concentrate and the costs of the basic operations of the fuel cycle. Resources are sufficient for the needs of nuclear power production based on LWR's without closing the fuel cycle for at least up to the year 2010; in the subsequent period fuels of higher price categories would have to be used (> or approx. 130 $/kg U). The manufacture of U concentrate after culmination in the years 1979 to 1980 is declining as is its price. Fuel material on an operation scale (15a t/year and more) is now being manufactured in 11 countries, with the US leading followed by Canada and Japan. From the point of view of technology the following methods are interesting: processing complex ores (USSR), the use of wastes from the production of nuclear purity uranium in agriculture (Canada), single-stage reconversion of UF6 to UO2 (the so-called IDR process in the UK), chemical methods of uranium enrichment (France and Japan), etc. Great attention is being devoted to the design and construction of spent fuel reprocessing plants and thus the introduction of the closed fuel cycle which is the only way towards the full utilization of uranium, to the transition to fast reactors and the extended service life of nuclear power way into the next millenium.

  12. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Venezuela. Draft

    International Nuclear Information System (INIS)

    The IUREP Orientation Phase Mission to Venezuela believes that the Speculative Uranium Resources of that country fall between 2,000 and 42,000 tonnes. This assumes that a part of the Speculative Resources would be extracted as by-product uranium from wet-process phosphoric acid production. Past exploration in Venezuela has resulted in the discovery of very few uranium occurrences and radioactive anomalies except for the many airborne anomalies recorded on the Guayana Shield. To date no economic deposits or significant uranium occurrences have been found in Venezuela except for the uraniferous phosphorites in the Cretaceous Navey Formation which are very low grade. The uranium occurrences and radioactive anomalies can be divided according to host rock into: (1) Precambrian crystalline and sedimentary rocks, (2) Cretaceous phosphorite beds, (3) continental sandstone, and (4) granitic rocks. The greatest geological potential for further uranium resources is believed to exist in the crystalline and sedimentary Precambrian rocks of the Guayana Shield, but favorable geological potential also exist in younger continental sandstones. Since the Guayana Shield is the most promising for the discovery of economic uranium deposits most of the proposed exploration effort is directed toward that area. Considerable time, effort and capital will be required however, because of the severe logistical problems of exploration in this vast, rugged and inaccessable area, Meager exploration work done to date has been relatively negative suggesting the area is more of a thorium rather than a uranium province. However because of the possibility of several types of uranium deposits and because so little exploration work has been done, the Mission assigned a relatively small speculative potential to the area, i.e. 0 to 25,000 tonnes uranium. A small speculative potential (0 to 2,000 tonnes) was assigned to the El Baul area in Cojedes State, in the Llanos Province. This potential is postulated

  13. Evaluation of uranium geochemical anomalies in the Kings Mountain area, Charlotte 10 x 20 Quadrangle. National Uranium Resource Evaluation Program

    International Nuclear Information System (INIS)

    The Savannah River Laboratory (SRL) was involved in the National Uranium Resource Evaluation (NURE) from 1974 through 1981. The SRL role was to design, conduct, and report the data from a geochemical reconnaissance of almost half the continental United States. The purpose of the work was to provide a basis for evaluating the uranium potential of areas and to identify areas meriting conventional geologic followup. In this program, more than 275,000 samples of stream sediment, soil, vegetation, and ground or surface water were collected. As a part of the development program to support interpretation of the geochemical data, SRL evaluated a series of geochemical anomalies identified by reconnaissance data. Subcontractors were selected to conduct field scintillometer surveys, compile geologic maps, collect additional samples, or provide other services required for a given study. This report summarizes the results of a study in the Charlotte 10 x 20 quadrangle, based on data from the hydrogeochemical and stream sediment reconnaissance. The study includes a geologic report and map prepared for SRL by David E. Howell; chemical analyses of individual monazite and zircon grains from stream sediments in the study area; and analyses of three zircon grains from near Antreville, South Carolina. Normal editing of the report was not possible before the termination of the NURE program. Thus, typographical and conceptual errors that may be present have not been corrected, and the reader is cautioned to use professional judgement in interpreting the data. 29 figures, 9 tables

    International Nuclear Information System (INIS)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) Mission to Rwanda. The IUREP Orientation Phase Mission to Rwanda estimates that the Speculative Resources of that country fall within the range of 500 to 5 000 tonnes of uranium. The majority of this potential is expected to be located in the Precambrian Ruzizian, especially in conjunction with tectonized pegmatoidal remobilizations of metamorphic sediments of western Rwanda. Other favourable geological environments include lamprophyric dikes and post tectonic granites of central Rwanda. The Mission recommends that over a period of five years approximately US$4.2 million be spent on exploration in Rwanda. The majority of this would be spent on airborne and ground geophysical surveys ($1.5 million) and exploration drilling ($1 million). Prospecting, trenching and tunneling and analytical work would require the remainder of the $4.2 million ($1.7 million). (author)

The IUREP Orientation Phase Mission to Burundi estimates that the Speculative Resources of that country fall within the range of 300 to more than 4 100 tonnes of uranium. The potential is rather evenly distributed throughout the Proterozoic of Burundi in various geological environments (unconformity, hydrothermal, fault controlled, etc.). The mission recommends that over a period of five years U.S. $ 3 to 4.5 million be spent on exploration in Burundi, with even spending on the various exploration techniques as e.g. prospecting, drilling trenching, geophysical surveys, analyses, etc. (author)

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (TUREP) Mission to Peru. The IUREP Orientation Phase Mission to Peru estimates that the Speculative Resources of that country fall within the range of 6 000 to 11 000 tonnes uranium. The majority of this potential is expected to be located in Late Tertiary ignimbrites and associated sediments in the high Andes of southern Peru. Other favourable geological environments include calcretes, developed from Tertiary volcanogenic sources over the Precambrian in the Pacific Coastal desert in southern Peru, and Hercynian subvolcanic granites in the eastern Cordillera of southern Peru. The Mission recommends that over a period of five years approximately U.S. $10 million be spent on exploration in Peru. The majority of this would be spent on drilling ($5 million) and tunnelling ($2 million) with an additional $3 million on surface and airborne radiometric surveys. (author)

  17. Improvement quality of the uranium resources at Kalan-West Kalimantan

    International Nuclear Information System (INIS)

    Aware of uranium low prices in the world, it is necessary to take efficient and optimum actions, so that the status of the uranium resources at Kalan will be ready for exploitation at the right moment to strengthen the development of nuclear power plants. The improvement activities should be done by the observation of the economic and technology aspects. For examples, the activities can be conducted in the form of sensivity analysis, comparative study, integrated data base collections (topography, drill holes data, mining, processing result). the activities include data processing, evaluating and modeling. Those activities can be successfully executed by the help of information and computation technology rapid advancement, sophisticated computer hardware and software, as well as professional human resources development.

Other potentially favorable geologic environments include Cretaceous phosphorite beds, continental sandstone and granitic rocks. The mission recommends that approximately US $18 million be spent on exploration in Venezuela over the next five years. The majority of this expenditure would be for surface surveys utilizing geologic studies, radiometric and geochemical surveys and some drilling for geologic information. Additional drilling would be required later to substantiate preliminary findings. (author)

  19. The ways of harmonization of uranium resources accounting systems on a global scale

    International Nuclear Information System (INIS)

    Resource classification systems used today in different countries make reference to the same principals: geological variability, commercial importance and level of preparedness for production. However, some countries with mining industries and established traditions use different classifications that are difficult to harmonize. To assist in developing a common international classification four issues are proposed for discussion: 1) existence of production facilities for producing resources; 2) need for low production cost categories compatible with current market prices; 3) specifying the degree of accuracy for various categories of resources and 4) in situ versus recoverable resource estimates. Based on these concepts revisions are proposed to the IAEA uranium classification system. Examples are also given of resource classifications for the Streltzovskoe deposit, Krasnokamensk. (author)

    International Nuclear Information System (INIS)

    Portugese Timor is approximately one half of an island in the Malay archipelago, with an area of 19,000 sq km.- For purposes of this study the whole island is considered, Recent information has been difficult to find, and although a geologic map is available, the geologic descriptions are sketchy. There has been no record of mineral occurrence or resources on Timor, and the island is primarily basic volcanic. No uranium potential has been estimated for the island. (author)

  1. International symposium on isotope hydrology and integrated water resources management. Book of extended synopses

    International Nuclear Information System (INIS)

    Scarcity of freshwater, degradation of its quality, and increasing demand has motivated ongoing concern in the international community for more effective utilization of freshwater resources. The IAEA's symposia on the use of isotope techniques in water resources development and management have become a recurrent event held every four years. They have provided an international forum for a comprehensive review of the present state-of-the-art and recent advances made in this specific field as well as a basis for delineation of further research and development needs. The year 2003 marks the 40th anniversary of the first IAEA water resources symposium. Increasing use of isotope techniques over the past four decades, in part due to efforts of IAEA, has enhanced availability and effective use of isotopes to address water resources management issues. The Symposium covers a multi-disciplinary spectrum of research and applications of isotope techniques. The participation of isotope specialists, hydrologists, hydrogeologists, geochemists, environmental scientists and water managers is welcomed. The Organizers further encourage the participation and contribution of graduate students in these fields. The major areas covered include: Water cycle processes in the atmosphere and hydrosphere, including surface water, groundwater, and watershed-based studies, age dating of young groundwaters, water, carbon and nutrient cycling processes at the land-ocean-atmosphere interface, recent advances in analytical techniques for isotope hydrology and field applications of isotopes in groundwater or surface water resources management. This book of synopses covers oral presentations and poster sessions

  3. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Turkey. September to November 1980

    International Nuclear Information System (INIS)

    The IUREP Orientation Phase Mission to Turkey estimates the Speculative Resources of the country to lie between 21 000 and 55 000 tonnes uranium. Past exploration in Turkey, dating from 1953, has indicated a very high number of uranium occurrences and radioactive anomalies, but ore deposits of significant size and grade have not been found. Present reserves amount to 4 600 tonnes uranium which can be allocated to approximately 15 sandstone type deposits in Neogene continental sediments. Several hundreds of other occurrences and radioactive anomalies exist where ore reserves have not been delineated. The uranium occurrences and radioactive anomalies can be divided according to host rock into (a) crystalline massif and (b) Tertiary continental sediment. The greatest geological potential for further resources is estimated to exist in the above mentioned two geological terrains. The most favourable geological potential exists in Neogene continental sedimentary basins near the crystalline massifs. Because surface exploration in the known favourable areas such as the Koepruebasi Basin has been so systematic, extensive, and successful, it is improbable that additional surface work will have much effect in increasing the number of new radioactive anomalies or uranium occurrences detected at the surface in these areas. Surface survey work in these areas should be mainly designed to assist the understanding of structures at depth. Surface reconnaissance survey work is, however, required in other parts of the above mentioned two geological terrains in this country. Before starting such a reconnaissance survey in new areas, the Mission suggests that a careful and extensive library study be conducted in close co-operation with sedimentologists, petrologists, and remote sensing specialists. The Mission suggests that in the medium term, 8 to 10 years, some 85 - 110 million U.S. Dollars be spent on airborne and ground surveys, including geological, radiometric, geochemical, and

  4. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Uganda. Draft. November 1982 - January 1983

    International Nuclear Information System (INIS)

    At present, there are no reasonably assured resources of uranium in Uganda in any price category. Speculative resources are restricted to 2,400 metric tons of uranium in an apatite deposit, which in the past has been actively mined for phosphate. The possible recovery of this uranium is dependent upon a number of economic and technological conditions which have never been thoroughly studied. Although the geology of Uganda holds some interesting possibilities for hosting uranium deposits, the studies conducted between 1949 and 1979 were limited to known radioactive occurrences and anomalies in limited areas which had little economic significance. Vast areas, less known and less accessible were completely ignored. Uranium exploration must therefore be started again in a systematic manner using modern methods. The current economic situation in Uganda is so critical that International technical and financial assistance is vitally needed to help rehabilitate the Geological Survey and Mines Department. Uganda currently can offer only very restricted services. The transportation system is quite deficient: the railway does not presently cross the frontier with Kenya, and all equipment and goods must be transported from Mombasa by road. Housing is in very short supply, and many basic commodities are often unobtainable. Any organization or private company which begins an exploration program in Uganda must plan to import essentially all the equipment and supplies it shall require. It shall also have to construct offices and staff housing, and import and stockpile fuel and staple goods, so as not to be at the mercy of the (at times) inadequate local supplies. It shall most probably also have to provide basic local and imported food to its Ugandan staff and should plan to pay much higher local salaries than is customary. Lastly, it will have to provide its own fleet of trucks and organize its own transport system. (author)

  5. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Madagascar. September-October 1981

    International Nuclear Information System (INIS)

    This study, resulting from the IUREP Orientation Mission to Madagascar, includes the reported information on infrastructure, mining regulations and conditions made available to the Mission. Within the structure of the centrally planned economic system, uranium exploration and mining is considered the exclusive activity of OMNIS, an organization founded by the State for that purpose (Office Militaire National pour les Industries Strategiques). Madagascar has a long history of prospection and small-scale exploitation of uranium (thorium and radium). Some of this activity dates back to 1909, culminating in significant production of both uranium and thorium (in excess of 5900 tonnes of uranothorianite) by the CEA and private contractors in the Fort Dauphin area from 1955 to 1968. Past exploration and development work in a number of areas, notably by the CEA, OMNIS and the IAEA/UNDP, is reviewed and the uranium resources and mineral indications reported. The areas rated at present as the more important and which continue to be investigated (by OMNIS, in conjunction with IAEA/UNDP projects) in the order of priority are: the Fort Dauphin area, the Karroo formation and the Neogene lacustrine basin at Antsirabe. The Mission estimates that Madagascar has a moderate potential for undiscovered resources; it is estimated that such speculative resources could lie within the range of 4000 - 38000 tonnes U. In addition there are areas with as yet untested environments and with no known occurrences which may be favourable but which will require prospection. Modifications to existing programmes and new programmes are suggested. Policy alternatives are reviewed

    About 1 million acres of Federal land in the Grand Canyon region of Arizona were temporarily withdrawn from new mining claims in July 2009 by the Secretary of the Interior because of concern that increased uranium mining could have negative impacts on the land, water, people, and wildlife. During a 2-year interval, a Federal team led by the Bureau of Land Management is evaluating the effects of withdrawing these lands for extended periods. As part of this team, the U.S. Geological Survey (USGS) conducted a series of short-term studies to examine the historical effects of breccia-pipe uranium mining in the region. The USGS studies provide estimates of uranium resources affected by the possible land withdrawal, examine the effects of previous breccia-pipe mining, summarize water-chemistry data for streams and springs, and investigate potential biological pathways of exposure to uranium and associated contaminants. This fact sheet summarizes results through December 2009 and outlines further research needs.

  7. Uranium resource assessment through statistical analysis of exploration geochemical and other data. Final report

    International Nuclear Information System (INIS)

    We have developed a procedure that can help quadrangle evaluators to systematically summarize and use hydrogeochemical and stream sediment reconnaissance (HSSR) and occurrence data. Although we have not provided an independent estimate of uranium endowment, we have devised a methodology that will provide this independent estimate when additional calibration is done by enlarging the study area. Our statistical model for evaluation (system EVAL) ranks uranium endowment for each quadrangle. Because using this model requires experience in geology, statistics, and data analysis, we have also devised a simplified model, presented in the package SURE, a System for Uranium Resource Evaluation. We have developed and tested these models for the four quadrangles in southern Colorado that comprise the study area; to investigate their generality, the models should be applied to other quandrangles. Once they are calibrated with accepted uranium endowments for several well-known quadrangles, the models can be used to give independent estimates for less-known quadrangles. The point-oriented models structure the objective comparison of the quandrangles on the bases of: (1) Anomalies (a) derived from stream sediments, (b) derived from waters (stream, well, pond, etc.), (2) Geology (a) source rocks, as defined by the evaluator, (b) host rocks, as defined by the evaluator, and (3) Aerial radiometric anomalies

  8. Uranium

    International Nuclear Information System (INIS)

    The uranium production industry is well into its third recession during the nuclear era (since 1945). Exploration is drastically curtailed, and many staffs are being reduced. Historical market price production trends are discussed. A total of 3.07 million acres of land was acquired for exploration; drastic decrease. Surface drilling footage was reduced sharply; an estimated 250 drill rigs were used by the uranium industry during 1980. Land acquisition costs increased 8%. The domestic reserve changes are detailed by cause: exploration, re-evaluation, or production. Two significant discoveries of deposits were made in Mohave County, Arizona. Uranium production during 1980 was 21,850 short tons U3O8; an increase of 17% from 1979. Domestic and foreign exploration highlights were given. Major producing areas for the US are San Juan basin, Wyoming basins, Texas coastal plain, Paradox basin, northeastern Washington, Henry Mountains, Utah, central Colorado, and the McDermitt caldera in Nevada and Oregon. 3 figures, 8 tables

  9. Unconformity-related uranium-gold deposits of northern Australia: Resources, genesis and exploration

    International Nuclear Information System (INIS)

    Australia has a uranium resource of 370 kt U3O8 (313 kt U) contained in unconformity-related deposits. Over 85% of this resource is located in the Alligator Rivers Province of the Northern Territory. In addition to uranium, several of the deposits here contain economic gold (38t have so far been delineated) and two contain major amounts of platinum-group metals. Uranium-gold deposits of the Alligator Rivers Provinces are in many ways similar to deposits of the Athabasca Basin in Saskatchewan (Canada). They are located at the unconformity between Mid Proterozoic clastic rocks and older metamorphic basement. Ore is associated with fault zones which in some cases transgress and offset the unconformity. Ore is enveloped by intense clay-sized phyllosilicate alteration haloes. Differences (i.e. lower grade, no ore in sandstone, no Ni-Co-As ore) can largely be attributed to the effects of extensive erosion and weathering which has exposed the Alligator Rivers deposits, and overall lack of exploration in areas of thick sandstone cover. All the known deposits in the Alligator Rivers Province were discovered by relatively simple airborne or ground radiometric surveys. Modern, geophysical methods as are routinely employed in Saskatchewan (such as airborne TEM), have not been tried in the Alligator Rivers Province. There has been a paucity of exploration in the Alligator Rivers Province in the past 15 years, as a result of creation of a national park over the most prospective area.

  11. Planning for a major expansion of the olympic dam copper/uranium resource in South Australia

    International Nuclear Information System (INIS)

    Full text: Full text: The polymetallic Olympic Dam deposit in northern South Australia contains the world's largest known economic uranium resource. The current resource estimate is 3,970 million tones at 0.4 kg/t U308. Uranium is a co-product of an existing operation that also produces copper, gold and silver. Production began in 1998. Ore mined in 2006 is expected to be close to 10 million tones to produce 4,500 tonnes of uranium oxide and 220,000 tonnes of copper cathode. BHP Billiton is undertaking a pre-feasibility study into expanding annual production capacity to about 15,000 tonnes of uranium and 500,000 tonnes copper. Subject to successful completion of the pre-feasibility study and a final feasibility study, construction of the expansion could begin by early 2009, with the expanded production capacity being commissioned in 2013. The resource estimate has been significantly increased by drilling of the so-far undeveloped southern section of the orebody. Current planning indicates that this section could be mined by open pit. Ore is at depth and extends from 350 metres to about 1000 metres below surface. The existing operations facilities at Olympic Dam comprise an underground mine, and a mineral processing plant and associated infrastructure which would be expanded to support expanded mining. Major items of infrastructure could include a new powerline, water pipeline and associated coastal desalination plant, a rail link to Olympic Dam from the existing national network and further development of the Roxby Downs township (current population 4,000). The operation is regulated by an Indenture Agreement with the South Australian Government. To enable the expansion to proceed, the Indenture Agreement will be renegotiated. The operation is also regulated by the Federal Government. An Environmental Impact Statement is being developed to secure the necessary State and Federal approvals. A land access agreement is being negotiated with indigenous groups. Plans for

  13. Downscaled estimate of uranium resources produced from phosphates and impact on the penetration of sodium fast reactors

    International Nuclear Information System (INIS)

    Future energy demand scenarios elaborated by international organisations are always more ambitious in terms of the installed nuclear power required, particularly when it comes to meeting requirements to curb climate change. The availability of natural uranium resources is a major constraint in terms of meeting this demand. The first part of this paper outlines the current assessment of uranium resources contained in phosphate rocks, which are far from being as abundant as some studies may have first predicted. Furthermore, the production of uranium as a by-product of phosphate is determined by the world production of phosphoric acid. The exorbitant cost of producing uranium alone (without recovering the phosphoric acid) would not overcome this limit on the production capacity. The second part of the document analyses the impact of such a reduction in uranium resources on how the world's nuclear fleet evolves. Different assumptions on the global uranium resources are taken into consideration. Sodium fast reactors (SFR) will be built in line with the availability of plutonium, including fast breeders when necessary. The capacity of the nuclear industry to meet the different power demand forecasts around 2150 is therefore examined. (author)

  14. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Peru. August - October 1981

    International Nuclear Information System (INIS)

    The IUREP Orientation Phase Mission to Peru believes that the Speculative Resources of that country fall between 6,000 and 11,000 tonnes uranium. There has been no uranium production in Peru and there are no official estimates of uranium resources. Past exploration in Peru (dating from about 1952) has indicated a paucity of valid uranium occurrences and radioactive anomalies. Only recently (1980) have anomalous areas been identified, (Macusani-Picotani). The identified Speculative Resources are mainly in Late Tertiary ignimbrites and associated sediments in the high Andes of southern Peru. Geologically, there are direct parallels between these resources and deposits of the Los Frailes areas of neighbouring Bolivia. Other minor Speculative Resources may be present in calcretes developed from Tertiary volcanogenic sources over the Precambrian in the Pacific Coastal desert of southern Peru but no positive indications have been recognised. Hercynian sub-volcanic granites in the eastern cordillera of southern Peru may have some associated Speculative Resources both intra and extra granitic. No Speculative Potential could be identified in Permo-Triassic or Tertiary post tectonic continental sediments anywhere in Peru. Such potential may exist but further reconnaissance of the continental late Tertiary basins, with positive indications would be required before inclusion of potential in this category. Recent discoveries in the volcanogenic environment of southern Peru have been by carborne, helicopter borne and on on-foot reconnaissance of isolated areas. It is recommended that there be a more systematic, integrated study of the entire volcanic district assisted by volcanic petrographic examination. Assessment of the known occurrences requires immediate subsurface study by drilling and exploration audits to assess their continuity, grade variation and thickness. This phase will be significantly more expensive than previous exploration. Non-core drilling should supplement

  15. Recent developments in uranium resources and production with emphasis on in situ leach mining. Proceedings of a technical meeting

    International Nuclear Information System (INIS)

    An important role of the International Atomic Energy Agency is establishing contacts between Member States in order to foster the exchange of scientific and technical information on uranium production technologies. In situ leach (ISL) mining is defined as, the extraction of uranium from the host sandstone by chemical solutions and the recovery of uranium at the surface. ISL extraction is conducted by injecting a suitable leach solution into the ore zone below the water table; oxidizing, complexing, and mobilizing the uranium; recovering the pregnant solutions through production wells; and, finally, pumping the uranium bearing solution to the surface for further processing. As compared with conventional mining, in situ leach is recognized as having economic and environmental advantages when properly employed by knowledgeable specialists to extract uranium from suitable sandstone type deposits. Despite its limited applicability to specific types of uranium deposits, in recent years ISL uranium mining has been producing 15 to 21 per cent of world output. In 2002, ISL production was achieved in Australia, China, Kazakhstan, the United States of America and Uzbekistan. Its importance is expected to increase with new projects in Australia, China, Kazakhstan and the Russian Federation. The Technical Meeting on Recent Development in Uranium Resources and Production with Special Emphasis on In Situ Leach Mining, was held in Beijing from 18 to 20 September 2002, followed by the visit of the Yili ISL mine, Xinjiang Autonomous Region, China, from 21 to 23 September 2002. The meeting, held in cooperation with the Bureau of Geology, China National Nuclear Cooperation, was successful in bringing together 59 specialists representing 18 member states and one international organization (OECD/Nuclear Energy Agency). The papers describe a wide variety of activities related to the theme of the meeting. Subjects such as geology, resources evaluation, licensing, and mine restoration were

One can however, make the assumption that geologically, there are probably several areas that contain the combination of favourable host rocks and source. The speculative potential of China is estimated to be in Category 5, 100,000 to 500,000 tonnes U. (author)

  1. National Uranium Resource Evaluation Program: the Hydrogeochemical Stream Sediment Reconnaissance Program at LLNL

    International Nuclear Information System (INIS)

    From early 1975 to mid 1979, Lawrence Livermore National Laboratory (LLNL) participated in the Hydrogeochemical Stream Sediment Reconnaissance (HSSR), part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). The Laboratory was initially responsible for collecting, analyzing, and evaluating sediment and water samples from approximately 200,000 sites in seven western states. Eventually, however, the NURE program redefined its sampling priorities, objectives, schedules, and budgets, with the increasingly obvious result that LLNL objectives and methodologies were not compatible with those of the NURE program office, and the LLNL geochemical studies were not relevant to the program goal. The LLNL portion of the HSSR program was consequently terminated, and all work was suspended by June 1979. Of the 38,000 sites sampled, 30,000 were analyzed by instrumental neutron activation analyses (INAA), delayed neutron counting (DNC), optical emission spectroscopy (OES), and automated chloride-sulfate analyses (SC). Data from about 13,000 sites have been formally reported. From each site, analyses were published of about 30 of the 60 elements observed. Uranium mineralization has been identified at several places which were previously not recognized as potential uranium source areas, and a number of other geochemical anomalies were discovered

  2. Final environmental statement related to the Plateau Resources Limited Shootering Canyon Uranium Project (Garfield County, Utah)

    The proposed action is the issuance of a Source Material License to Plateau Resources, Ltd., for the construction and operation of the proposed Shootering Canyon Uranium Project with a product (U3O8) production limited to 2.2 x 105 kg (4.9 x 105 lb) per year. Impacts to the area from the operation of the Shootering Canyon Uranium Project will include the following: alterations of up to 140 ha (350 acres) that will be occupied by the mill, mill facilities, borrow areas, tailings areas, and roads; an increase in the existing background radiation levels of the mill area as a result of continuous but small releases of uranium, radium, radon, and other, radioactive materials during construction and operation; socioeconomic effects on the local area, particularly the proposed community of Ticaboo, where the majority of workers will be housed during project construction and operation; and production of solid waste material (tailings) from the mill at a rate of about 680 MT (750 tons) per day and deposition as a slurry in an onsite impoundment area; construction and operation of the Shootering Canyon mill will provide employment and induced economic benefits for the region but may also result in some socioeconomic stress. On the basis of the analysis and evaluation set forth in this Environmental Statement, it is proposed that any license issued for the Shootering Canyon mill should be subject to certain conditions for the protection of the environment.

    International Nuclear Information System (INIS)

    Uranium (U) mining remains controversial in many parts of the world, especially in a post-Fukushima context, and often in areas with significant U resources. Although nuclear proponents point to the relatively low carbon intensity of nuclear power compared to fossil fuels, opponents argue that this will be eroded in the future as ore grades decline and energy and greenhouse gas emissions (GGEs) intensity increases as a result. Invariably both sides fail to make use of the increasingly available data reported by some U mines through sustainability reporting — allowing a comprehensive assessment of recent trends in the energy and GGE intensity of U production, as well as combining this with reported mineral resources to allow more comprehensive modelling of future energy and GGEs intensity. In this study, detailed data sets are compiled on reported U resources by deposit type, as well as mine production, energy and GGE intensity. Some important aspects included are the relationship between ore grade, deposit type and recovery, which are crucial in future projections of U mining. Overall, the paper demonstrates that there are extensive U resources known to meet potential short to medium term demand, although the future of U mining remains uncertain due to the doubt about the future of nuclear power as well as a range of complex social, environmental, economic and some site-specific technical issues. - Highlights: • An extensive data set on global uranium resources and classified by deposit type. • Comprehensive analysis of key trends, such as ore grades and recovery rates. • Energy and carbon intensity of production shows an increase as ore grades decline. • Mine rehabilitation often shows poor success or accounts of long-term effectiveness. • Real constraints on nuclear power remain safety and costs compared to alternatives

  4. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Thailand. February-March 1981

    International Nuclear Information System (INIS)

    The I.U.R.E.P. Orientation Phase Mission assesses the Speculative Uranium Resources in Thailand to be within the range of 1,500 to 38,500 tonnes U. This range is higher than the previous assessment in Phase I because the Mission recognizes additional favourable geological environments. At the same time, the untested and therefore the unknown degree of mineralization in some of these environments is acknowledged. Past exploration, dating from 1977, has been mainly confined to ground surveys of a small mineralized area and to airborne gamma-ray surveys of two small test areas. Ground reconnaissance work and prospecting has recognized some mineralization in several different host rocks and environments. Geological environments considered by the Mission to be favourable for uranium occurrences include sandstone of Jurassic to Triassic age, tertiary sedimentary basins (northern Thailand), tertiary sedimentary basins (southern Thailand), associated with fluorite deposits, granitic rocks, black shales and graphitic slates of the Paleozoic, associated with sedimentary phosphate deposits and associated with monazite sands. It is recommended that exploration for uranium resources in Thailand should continue. Planners of future exploration programmes should take the following activities into consideration. Rapid extension of carborne surveys to cover, without excessive overburdening, all areas having sufficient road density. Airborne gamma-ray surveys should be carried out in certain selected areas. In the selection of such areas, the considerable higher cost factor attendant on this method of surveying dictates that airborne surveys should only be carried out where carborne surveys prove ineffective (lack of adequate road network.) and where the topography is sufficiently even to assure a low but safe clearance and meaningful results. In certain areas, including the Khorat Plateau and the Tertiary Basins in northern and southern Thailand, there is a need for widely spaced

  5. Nuclear power has a bright outlook and information on uranium resources is our duty

    International Nuclear Information System (INIS)

    Full text: Because of its growth in number and in its average development level, and besides food supply, Human kind is facing three main challenges, water supply, energy supply and climate change. Nuclear power is not relevant to address all in the same proportion, however it may help addressing all of them. Therefore the question of uranium supply and more generally of resource sustainability is increasingly important. It is the kind of question drawing a complex blending of knowledge, hopes, dreams, mistakes and disinformation amongst pro-nuclear, anti, various stakeholders and of course the general public. Beyond the quality of the available information, beyond hard facts, beyond all the technicalities, it is essential to deliver a message that is easy to understand, that does reflect the real knowledge and properly identifies the unknowns. Another point is the question of the environmental impact of uranium mining. Again, properly recalling what was done, what has been achieved and what is planned will help to improve its general acceptance. These two topics are critical to a successful contribution of nuclear power to the challenges we are collectively facing. The economic production of uranium at the pace of nuclear power plants, i.e. in the long term, requires not only well run mining operations, but also the adequate level of information to reassure investors. This should come along with an adequate level of environmental protection to reassure the stakeholders while keeping the related expenses at a sound level. The uranium exploration, mining and environmental community has the duty to timely and effectively address all these points. (author)

  6. Sustainability of water cooled reactors - Energy balance for low grade uranium resources

    International Nuclear Information System (INIS)

    In October 2007 the European Parliament declared, that nuclear power is indispensable for the European Union for limiting CO2 emissions. Many countries revive their nuclear power programs or start building new nuclear power plants. However, the opponents of nuclear power claim that as uranium resources get exhausted the energy needed to mine low grade uranium ore will be larger than the energy that can be obtained from fission in a nuclear power plant. They conduct continuously their studies, publish their results in internet and present them at numerous meetings organized by antinuclear organizations. In particular they claim that the nuclear industry does not consider full energy costs of the nuclear fuel cycle, leaving aside the energy incorporated in materials and products bought from other industries and neglecting the energy needed for plant dismantling, mine area reclamation and waste management. This would result in loss of sustainability of nuclear power, with the negative energy balance expected within the next 40-60 years. In answer to that the Institute of Atomic Energy (IAE) in Poland has performed a study of available uranium resources, energy needed for mining and milling and the CO2 emissions in the whole uranium fuel cycle with special attention to back-end energy needs. The total energy needs for uranium mining were considered, including not only electricity needed for mining and milling, for water treatment and delivery to the mine and to the neighboring settlements, but also fuel for transportation and ore crushing, explosives for rock blasting, chemicals for uranium leaching and the energy needed for mine reclamation after completed ore exploitation. In contrast to the estimates of nuclear opponents based on mining experience with rich ores mined some 30 years ago, the study of IAE has used the most up to date data, reflecting the actual state-of-art mining practices. Since the opponents state clearly that the ore containing less than 0,013% U3

  7. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Cameroon. Draft

    International Nuclear Information System (INIS)

    The purpose of the International Uranium Resource Evaluation Project (IUREP) missions to host nations is to: Review the present body of knowledge pertinent to the existence of uranium resources, to review and evaluate the potential for the discovery of additional resources, and to suggest new exploration efforts which might be carried out in promising areas in collaboration with the countries concerned. Guidance in the achievement of these goals is provided through a check list of desired relevant information on: general background, the potential role of nuclear energy, and organizations involved, information on the mining industry, technical manpower employed or available, available maps, aerial photographs, and publications, national geological survey and organizations involved in uranium, private organizations involved in uranium exploration and mining, results of previous exploration, known uranium occurrences, plans for further work, legal and administrative requirements for exploration and logistical information on facilities available. The economy of CAMEROON is sound and continues to expand with an annual growth rates of 5-6%. Emphasis is placed on private investment with government participation in major development projects. The overall investment climate is good. Minerals exploration is carried out under nonexclusive Prospecting License and exclusive Exploration License that may later be converted to a Mining Lease or Mining Concession. Many of the conditions must be negotiated. Uranium is classified as a strategic mineral, and may be subject to special review. There is no defined policy on uranium development. Two government organizations are concerned with geology and mining. The INSTITUT DE RECHERCHES GEOLOGIQUES ET MINIERES (IRGM) conducts programs of geologic mapping and research, mineralogy, hydrology, and alternate energy sources. The DEPARTMENT OF MINES AND GEOLOGY (DMG) is responsible for all minerals exploration and mining. It includes a

  8. Long-term availability of uranium resources: a bivariate statistical approach

    International Nuclear Information System (INIS)

    This poster describes the bivariate supply model that is based on deposit cost and Uranium content, both being functions of grade and tonnage. This model is applied to the case of the United States taking into account known and unknown US deposits,a bias has been applied due to the discovery of bigger and richer deposits. In a next step the supply model will be used in the price formation mechanism which will allow long-term resource depletion to be included in the mid-term dynamics of the price mechanism. Today conventional price formation mechanisms are generally limited to short/mid-term with limited production rates but with no resource depletion

  9. Uranium deposits of Ukraine for ISL mining: Developments in uranium resources of Ukraine for in situ leach (ISL) uranium mining - Historical analysis, operational, geological, environmental and economic aspects

    International Nuclear Information System (INIS)

    From 1961-1968 uranium production center of Ukraine, East Concentrating Mill and Zheltiye Vody Hydrometallurgical Plant has carried out first Ukrainian In Situ Leaching (ISL) uranium project in Devladovo of Sofiivka district (Dnipropetrovska province) and in 1964-1969 the second in Bratske of Mikolaivska province. The experiences were executed with the acid leach system. Despite its limited applicability for this time to specific types of uranium deposits called as Sandstone Uranium Deposits, the in situ leaching (ISL) method of uranium production has grown in importance for its competitive cost and has proven to be an environmentally sound technology with very little disturbance to the environment. It was also recognized that there are two distinct approaches of ISL uranium production being practiced in Eastern Europe, in particular, in Ukraine, and in the USA, later in Kazakhstan and Uzbekistan. Commercial in situ leach (ISL) uranium mining in the United States began in the mid-1970s. In 1968, for the first time in the former USSR, the East Concentration Mill and Zheltiye Vody Hydrometallurgical Plant has implemented In Situ Leach (ISL) uranium mining technology in the Devladovske uranium deposit.

  10. National uranium resource evaluation program. Hydrogeochemical and stream sediment reconnaissance basic data for Oklahoma City NTMS Quadrangle, Oklahoma. Uranium resource evaluation project

    International Nuclear Information System (INIS)

    Field and laboratory data are presented for 812 groundwater samples and 847 stream sediment samples. Statistical and areal distributions of uranium and other possibly uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Based on the results from groundwater sampling, the most promising formations for potential uranium mineralization in the quadrangle are the Permian Bison, Purcell-Salt Plains-Kingman, Fairmont, Dog Creek, Chickasha, Duncan, and Cedar Hills Formations. These units are characterized by relatively high average concentrations of uranium, conductivity, arsenic, calcium, lithium, molybdenum, and sulfate. In addition, groundwaters from the Pennsylvanian Oscar Formation are characterized by values above the 85th percentile for uranium, conductivity, the uranium/sulfate ratio, arsenic, and vanadium. Results of stream sediment sampling indicate that the most promising formations for potential uranium mineralization include the same Permian Formation as indicated by groundwater sampling (Bison, Purcell-Salt Plains-Kingman, Fairmont, Dog-Creek, Chickasha, Duncan, and Cedar Hill Formations) in an area where these formations crop out north of the North Canadian River. Stream sediment samples from this area are characterized by concentrations above the 85th percentile for uranium, thorium, arsenic, lithium, manganese, and vanadium

  11. Some suggestions related to the harmonization of uranium resource classification. Summary

    International Nuclear Information System (INIS)

    The B and C1 categories of uranium reserves that are characteristic for Uzbekistan can probably be compared to the explored reserves based on IAEA classification. The first (B) category, in deposits of the sandstone type, are from areas where full scale exploration (geotechnological) programme has been carried out (using drill hole grid of 50x25 m). The C1 category, also in deposits of the sandstone type, are from areas where the drill hole grid are of 200x50 to 100 m and sometimes as close as 100x25 to 50 m. Reserves of C2 category, referred to as preliminary estimated reserves, are found in sandstone type deposits where drilling programme followed a 400x50 to 100 m grid and sometimes a 200x50 to 100 m grid in the case where the deposit has a more complex morphology. According to the stages accepted in the Republic, the stage of preliminary estimate is followed by detailed estimate. The advisability of conducting detailed estimate is governed by the result of works in the previous stage. From this explanation it would be appropriate to classify the reserves of C2 category as a preliminary estimated additional reserve of category I (''PODZ-I'' in Russian), although a large part of C2 reserves was already included in the explored reserves. For the preliminary estimated additional reserves of category II (''PODZ-II'' in Russian) it is suggested to include P1 category, which is the predicted resources in areas that are under current exploration activities. It is further suggested to include P2 resources into category of prospective deposits (''PZ'' in Russian), that might occur in area within known uranium districts where new reserves of specific types of deposits might be found or in new areas with similar geological environment that is known to contain uranium deposits. For the technical and economic evaluation (called ''TEO'' in Russian) it is advisable to conduct the required works and prepare a preliminary ''TEO'', which was used in the former USSR, and is still

  13. Lung cancer in uranium miners: A tissue resource and pilot study. Progress report, September 25, 1992 - May 31, 1993

    International Nuclear Information System (INIS)

    This project involves two related activities directed toward understanding respiratory carcinogenesis in radon-exposed former uranium miners. The first activity involves a continuation of the tissue resource of lung cancer cases from former underground uranium miners and comparison cases from non-miners. The second activity is a pilot study for a proposed longitudinal study of respiratory carcinogenesis in former uranium miners. The objectives are to facilitate the investigation of molecular changes in radon exposed lung cancer cases and to develop methods for prospectively studying clinical, cytologic, cytogenetic, and molecular changes in the multi-event process of respiratory carcinogenesis, and to assess the feasibility of recruiting former uranium miners into a longitudinal study that collects multiple biologic specimens

  15. Uranium and thorium in granitic rocks of northeastern Washington and northern Idaho, with comments on uranium resource potential

    Science.gov (United States)

    Nash, J. Thomas

    1979-01-01

    Northeastern Washington and northern Idaho is a uranium province in which many Cretaceous and Tertiary granitic plutons contain abnormal amounts of uranium. Mean uranium content of 108 samples of granitic rock is 8.8 parts per million (ppm), more than twice normal for rocks of this composition. The mean thorium content, 20.3 ppm, and mean Th/U, 3.19, are normal. The most uraniferous and fertile rocks are the peraluminous two-mica granitic suite, although not all two-mica plutons are enriched in uranium. The muscovite-bearing suite has mean uranium content of 22.3 ppm, mean thorium content of 22.8 ppm, and mean Th/U of 2.82. Porphyritic quartz monzonite of the Midnite mine, which I interpret to be a two-mica granitic rock, is especially radioactive with mean U of 14.7 ppm, mean Th of 32.1 ppm, and mean Th/U of 2.72. Mean uranium and thorium contents of the two-mica granitic plutons are significantly different from those of the calcalkaline hornblende granitic suite, which are mean U, 5.0 ppm; mean Th, 17.6; and mean Th/U, 3.78. Biotite granitic rocks containing no hornblende or muscovite appear to be an intermediate suite in terms of U and Th, or possibly are variants of both hornblende and muscovite type; mean U is 3.88 ppm, mean Th is 14.4 ppm, and mean Th/U is 3.03 as calculated from the more abundant data of Castor and others (1978). occurrence of uranium and thorium in the muscovite and hornblende suites is systematically different. Many muscovite-bearing rocks are much more enriched in uranium (>15 ppm) than they are in thorium, and have a relatively low Th:U correlation coefficient of +0.409. Many of the uraniferous muscovite-bearing rocks contain less than 20 ppm Th, probably a consequence of forming by anatexis of thorium deficient sedimentary rocks. Uranium and thorium variation is much more regular in the hornblende suite, which has a Th:U correlation coefficient of +0.780. Uranium in the muscovite suite is held primarily in magnetite and biotite, and

  16. A review of Spanish uranium resources and recent developments in the province of Salamanca

    International Nuclear Information System (INIS)

    Uranium exploration activities in Spain carried out during the 1950-1992 period, led to the discovery of a number of deposits in different geological environments. Presently there is only activity at the FE area in Salamanca province, where the only remaining mining centre is located. A new dynamic leaching processing plant with a capacity of up to 950 t U3O8 t/year began operation in 1993, at FE mine. The development and planning of the mining in the open pits of ENUSA (province of Salamanca, Spain) under the present low market prices, has led to the implementation of a working scheme, based on the following concepts: Detailed knowledge of the distribution and quality of the mineralization by sufficiently close spaced drilling, with 3D positioning and grade estimation by deviation and gamma ray probing. Use of either geostatistical or arithmetical grade interpolation techniques, properly validated with production, adapted to the density of the information available. Economic optimization of the open pit, by means of the 3D Lerchs-Grossmann technique, as a guide for the final pit design. Calculation of the optimal pit shapes and recoverable resources under different price conditions. These techniques implemented by means of computerized data acquisition and processing systems, are used to face with versatility, the present economic conditions. A full review of the uranium deposits in the province of Salamanca is being carried out with these means. (author). 18 figs

  17. Understanding data on resources

    International Nuclear Information System (INIS)

    More information and misinformation are available about the resources of uranium than of any other mineral commodity, save petroleum, and perhaps also gold. Governments of major uranium producing countries regularly publish estimates of their national resources and reserves of uranium, albeit on varying definitions. These national data are collated in the periodic joint Organization for Economic Co-operation and Development (OECD)/International Atomic Energy Agency (IAEA) reports known as the Red Books. Whilst the figures are set out in apparently common format, the reports clearly indicate the differences between coverage of the various national definitions, and the criteria they use. It is emphasized that 'grey zones in correlation are unavoidable, particularly as the resources become less assured. This paper examines some of the background to the Red Book data which has a bearing on their interpretation. (author)

  19. Uranium resources and their implications for fission breeder and fusion hybrid development

    International Nuclear Information System (INIS)

    Present estimates of uranium resources and reserves in the US and the non-Communist world are reviewed. The resulting implications are considered for two proposed breeder technologies: the liquid metal fast breeder reactor (LMFBR) and the fusion hybrid reactor. Using both simple arguments and detailed scenarios from the published literature, conditions are explored under which the LMFBR and fusion hybrid could respectively have the most impact, considering both fuel-supply and economic factors. The conclusions emphasize strong potential advantages of the fusion hybrid, due to its inherently large breeding rate. A discussion is presented of proposed US development strategies for the fusion hybrid, which at present is far behind the LMFBR in its practical application and maturity

    1979-10-31

    Results of a reconnaissance geochemical survey of the Beeville Quadrangle, Texas are reported. Field and laboratory data are presented for 373 groundwater and 364 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. The groundwater data indicate that the northwestern corner of the quadrangle is the most favorable for potential uranium mineralization. Favorability is indicated by high uranium concentrations; high arsenic, molybdenum, and vanadium concentrations; and proximity and similar geologic setting to the mines of the Karnes County mining district. Other areas that appear favorable are an area in Bee and Refugio Counties and the northeastern part of the quadrangle. Both areas have water chemistry similar to the Karnes County area, but the northeastern area does not have high concentrations of pathfinder elements. The stream sediment data indicate that the northeastern corner of the quadrangle is the most favorable for potential mineralization, but agricultural practices and mineralogy of the outcropping Beaumont Formation may indicate a false anomaly. The northwestern corner of the quadrangle is considered favorable because of its proximity to the known uranium deposits, but the data do not seem to support this.

  4. National Uranium Resource Evaluation Program. Hydrogeochemical and stream sediment reconnaissance basic data for Plainview NTMS Quadrangle, Texas. Uranium Resource Evaluation Project

    International Nuclear Information System (INIS)

    Results of a reconnaissance geochemical survey of the Plainview Quadrangle, Texas are reported. Field and laboratory data are presented for 969 groundwater samples and 571 stream sediment samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. At least two different types of groundwater occur in the Plainview Quadrangle. One is associated with the Permian units and is characterized by high conductivity values with high concentrations of U, Mo, and sulfate. The other is associated with the Ogallala Aquifer System and is characterized by high alkalinity values and high concentrations of As, Li, Mo, Se, and V. Steam sediment results indicate that two distinct associations between uranium and other elements occur in the Plainview Quadrangle. An association consists of high soluble U values accompanied by relatively low total-to-soluble uranium ratios with high values for V, Li, and to a lesser extent, As and Se. This association is indicative of the type of secondary mineralization expected in sedimentary units which is related to commercial potential. The other association consists of high values of total U and high total-to-soluble U ratios with high values for Ba, Mn, Ti, Th, and Zr. This association is indicative of heavy and resistate mineral suites which are less favorable for commercial potential

  8. Seasonal effects on ground water chemistry of the Ouachita Mountains. National Uranium Resource Evaluation Program

    International Nuclear Information System (INIS)

    Samples from 13 ground water sites (10 springs and 3 wells) in the Ouachita Mountains were collected nine times during a 16-month period. Daily sampling of six sites was carried out over an 11-day period, with rain during this period. Finally, hourly sampling was conducted at a single site over a 7-hour period. The samples were analyzed for pH, conductivity, temperature, total alkalinity, nitrate, ammonia, sulfate, phosphate, chloride, silica, Na, K, Li, Ca, Mg, Sr, Ba, Fe, Mn, Zn, Cu, Co, Ni, Pb, Hg, Br, F, V, Al, Dy, and U. Despite the dry season during late summer, and wet seasons during late spring and late fall in the Ouachita Mountain region, there was no significant change in the ground water chemistry with season. Likewise, there was no significant change due to rain storm events (daily sampling) or hourly sampling. The report is issued in draft form, without detailed technical and copy editing. This was done to make the report available to the public before the end of the National Uranium Resource Evaluation. 9 figures, 19 tables

  9. System for obtaining high-integrity borehole fluid samples. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    A high-integrity borehole fluid sampling system has been developed by Bendix Field Engineering Corporation, prime contractor for the US Department of Energy Grand Junction Area Office as a part of the National Uranium Resource Evaluation program. Through the use of a high-pressure positive-displacement pump of stainless steel coupled to a Teflon delivery line, the system is designed for delivery of an uncontaminated and unfractionated fluid sample to the surface from depths of up to 300 meters. Inflatable packers may be used to isolate a zone of interest from which the representative sample is subsequently pumped. Specially designed sample receivers are used for storage of the sample under conditions comparable to downhole pressure conditions. In contrast to systems using conventional packer systems developed primarily for the oil industry, this system is capable of sealing uncased boreholes having large borehole caliper variations without the necessity of withdrawing the tool to change the packers. In addition, this new system does not introduce foreign material into the borehole since the system uses only resident borehole fluids to effect packer inflation. Thus, long-term sampling programs may be accomplished without compromising the integrity of subsequent sample acquisition

    International Nuclear Information System (INIS)

    Through developing stand remote sensing image, interpreting and inferring geological structure and extracting alteration information, we have divided China mainland in 8 feature regions, corrected and replenished several huge fractures which controlled the spatial pattern of magmatism and sedimentary basin in China, found out the shaded faults, volcanic structures and karst funnels which were related to regional uranium mineralization, identified the structural slope and local discharge zone, alteration feature of granite plutons and fracture zones which control the uranium mineralization. By combining remote sensing information with geology information, we have predicted 92 favor areas in China mainland for further uranium prospecting. (authors)

  14. National Uranium Resource Evaluation. General procedure for calibration and reduction of aerial gamma-ray measurements: specification BFEC 1250-B

    International Nuclear Information System (INIS)

    The information contained in this specification was acquired over the course of the US Department of Energy (DOE) National Uranium Resource Evaluation (NURE) program during the period 1974 through 1982. NURE was a program of the DOE Grand Junction Area Office to acquire and compile geologic and other information with which to assess the magnitude and distribution of uranium resources and to determine areas favorable for the occurrence of uranium in the United States. Bendix Field Engineering Corporation (BFEC) has been the operating contractor for the DOE Grand Junction facility. The requirements stipulated herein had been incorporated as contractual specifications for the various subcontractors engaged in the aerial gamma-ray surveys, which were a major aspect of the NURE program. Although this phase of NURE activities has been completed, there exists valuable knowledge gained from these years of experience in the calibration of gamma-ray spectrometer systems and in the reduction of calibration data. Specification BFEC 1250-B is being open-filed by the US Department of Energy at this time to make this knowledge available to those desiring to apply gamma-ray spectrometry to other geophysical problems

  16. Australia's uranium - greenhouse friendly fuel for an energy hungry world: a case study into the strategic importance of Australia's uranium resources for the inquiry into developing Australia's non-fossil fuel energy industry

    International Nuclear Information System (INIS)

    The terms of reference for the case study were to inquire into and report on the strategic importance of Australia's uranium resources. The Committee was asked to give particular attention to the: global demand for Australia's uranium resources and associated supply issues; potential implications for global greenhouse emission reductions from the further development and export of Australia's uranium resources; and the current regulatory environment of the uranium mining sector. The Committee indicated in its letters inviting submissions that it would also welcome comments in relation to six additional issues, relating to: whole of life cycle waste management; adequacy of social impact assessment, consultation and approval processes with traditional owners; health risks to workers and to the public from exposure to radiation; adequacy of regulation of uranium mining by the Commonwealth; the extent of federal subsidies and other mechanisms to facilitate uranium mining; and the effectiveness of safeguards regimes in addressing proliferation. These matters are addressed in the Committee's report, which consists of 12 chapters. The contents, findings and recommendations of each chapter are summarised as follows. The Committee's conclusions and recommendations are also summarised in a key messages section at the beginning of each chapter and in the conclusions section at the end of each chapter

    Steele, K. F.

    1982-08-01

    A hydrogeochemical ground water orientation study was conducted in the multi-mineralized area of the Ouachita Mountains, Arkansas in order to evaluate the usefulness of ground water as a sampling medium for uranium exploration in similar areas. Ninety-three springs and nine wells were sampled in Clark, Garland, Hot Springs, Howard, Montgomery, Pike, Polk, and Sevier Counties. Manganese, barite, celestite, cinnabar, stibnite, copper, lead, and zinc are present. The following parameters were determined: pH, conductivity, alkalinity, U, Br, Cl, F, He, Mn, Na, V, Al, Dy, NO/sub 3/, NH/sub 3/, SO/sub 4/, and PO/sub 4/. The minerals appear to significantly affect the chemistry of the ground water. This report is issued in draft form, without detailed technical and copy editing. This was done to make the report available to the public before the end of the National Uranium Resource Evaluation.

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Belize (Former British Honduras)

    International Nuclear Information System (INIS)

    Belize is a well-forested area of 22,960 square kilometers. Its capital is Belmopan. The country is generally flat north of the capital city. The flat, swampy Caribbean Coast of Belize gradually ascends to the low peaks of the Maya and Cockscomb Mountains (elevation to 1,120 meters). The area south of the Maya Mountains is much more rugged than the area to the north. The country is drained by seventeen rivers, the chief ones being the Belize, Hondo, New, Sibun, Monkey and Moho. There is 'hurricane danger in the July-October period. Belize has reportedly been surveyed by Gamma Ray Spectrometer for phosphates which probably would have contained sufficient uranium to be detectable. The survey traversed about 1,000 line kms along major north-south and east-west roads as well as many secondary roads and trails. The uranium readings ranged from 0. to 9.9 ppm with a uranium content of 1-2 ppm in the limestone areas and 2-7 ppm in the alluvium-covered areas. The U/Th ratio varied from 0.11 to 1.65. A recent traverse across the Mountain Pine Ridge batholith gave one reading as high as 36 ppm but the average was about 9-10 ppm. The upper 1000-3000 feet of core and cuttings from nine deep oil wells were checked for phosphates and uranium. Most of the core and cuttings were almost pure limestones. The P203 content was less than 0.05 percent and no uranium was detected. It is very doubtful that any significant uranium occurrences will be found in the sediments surrounding the Maya Mountain uplift. However, there is a slight chance that uranium might occur in the granites and pegmatites in the Maya Mountains. The potential of Belize is estimated to be in the less than 1.000 tonnes uranium range, considering the restricted range, of geologic environments encountered there

  20. Geological-geophysical criteria for the exploration of uranium mineral resources in the central region of Cuba

    International Nuclear Information System (INIS)

    The study of the regional geology, jointly with the airborne gamma spectrometric surveys, as well as the geophysical exploration in the region of central Cuba, allowed to define a series of favourable search indexes which indicate the possible presence of uranium resources and so to propose the most favourable areas and the genetic types of the possible uranium mineralization. The study region is located in the portion Southern Center of the Cuban archipelago, which has an extension of approximately 4308 Km2. Taking into account the geology, the rocks of the investigation area present a continental origin for the most part, and it are embrace for rocks of the terrestrial sub western Escambray and sequences of complex rocky belonging to the oceanic units. The register of the activity total gamma were made in counts per second (cps) and using geological survey scintillators, NaI(Tl), for field studies, type SRP-68-01 from the former USSR. For the definition of nature of the radioactive anomalies was used the Spectrometer of 4 channels (Ig, U(ra), Th and K) GAD-6 of the SCINTREX with an integration time for the readings of 300 seconds. For the of Radon222 determination in springs and water wells was used the Radiometer alpha de scintillations RGA-01 from the former USSR. The samples with anomalous concentrations of uranium detected during the geologic confirmation were sent to the laboratory for the gamma-ray spectroscopy analysis and for the mineralogical determinations. To the liquid samples were determined the uranium concentration by measurement with fluorimetry with the UA3 equipment; then were established the levels considered as anomalous for each case, taking into account the values of the regional background. It is concluded that on the geologic composition of the study area the criteria and search indexes are manifested with more frequency in the continental units and in a second place in the sequences of the volcanic arches belonging to the oceanic units

  2. Precambrian uranium-bearing quartz-pebble conglomerates: exploration model and United States resource potential

    Energy Technology Data Exchange (ETDEWEB)

    Houston, R.S.; Karlstrom, K.E.

    1979-11-01

    Uranium has been discovered in fluvial quartz-pebble conglomerates in most of the Precambrian shield areas of the world, including the Canadian, African, South American, Indian, Baltic, and Australian shields. Occurrences in these and other areas are shown. Two of these occurrences, the Huronian supergroup of Canada and the Witwatersrand deposit of South Africa contain 20 to 30 percent of the planet's known uranium reserves. Thus it is critical that we understand the origin of these deposits and develop exploration models that can aid in finding new deposits. Inasmuch as these uranium-bearing conglomerates are confined almost entirely to rocks of Precambrian age, Part I of this review begins with a discussion of Precambrian geology as it applies to the conglomerates. This is followed by a discussion of genetic concepts, a discussion of unresolved problems, and finally a suggested exploration model. Part II summarizes known and potential occurrences of Precambrian fossil placers in the world and evaluates them in terms of the suggested exploration model. Part III discusses the potential for important Precambrian fossil-placer uranium deposits in the United States and includes suggestions that may be helpful in establishing an exploration program in this country. Part III also brings together new (1975-1978) data on uranium occurrences in the Precambrian of the Wyoming Province. Part IV is a complete bibliography of Precambrian fossil placers, divided according to geographical areas. In total, this paper is designed to be a comprehensive review of Precambrian uranium-bearing fossil placers which will be of use to uranium explorationists and to students of Precambrian geology.

  8. Czechoslovak uranium

    International Nuclear Information System (INIS)

    Data and knowledge related to the prospecting, mining, processing and export of uranium ores in Czechoslovakia are presented. In the years between 1945 and January 1, 1991, 98,461.1 t of uranium were extracted. In the period 1965-1990 the uranium industry was subsidized from the state budget to a total of 38.5 billion CSK. The subsidies were put into extraction, investments and geologic prospecting; the latter was at first, ie. till 1960 financed by the former USSR, later on the two parties shared costs on a 1:1 basis. Since 1981 the prospecting has been entirely financed from the Czechoslovak state budget. On Czechoslovak territory uranium has been extracted from deposits which may be classified as vein-type deposits, deposits in uranium-bearing sandstones and deposits connected with weathering processes. The future of mining, however, is almost exclusively being connected with deposits in uranium-bearing sandstones. A brief description and characteristic is given of all uranium deposits on Czechoslovak territory, and the organization of uranium mining in Czechoslovakia is described as is the approach used in the world to evaluate uranium deposits; uranium prices and actual resources are also given.

  9. Inventory of uranium resources potency at Kawat area, upper Mahakam, East Kalimantan detailed prospecting stage

    International Nuclear Information System (INIS)

    Result of the general prospecting in East Kalimantan has found several radioactivity outcrop anomalies at upper Mahakam in the acid volcanic rock area which is approximately 25 km2 in wide. The objective of the research is to know detailed geological information and characteristic of uranium mineralization. Method of this research are detailed geological, radiometric and geochemical mapping 1:10.000 on scale. The lithology of Kawat area is composed of seven units of rock. They are black clay unit, feldspatic sandstone unit, Nyaan rhyolite unit, lower andesite unit, Kawat rhyolite unit, upper andesite unit and tuffaceous sandstone unit. Evolving fault is dextral fault and normal fault. The trending of dextral fault is west-east and southwest-northeast, meanwhile the trending of normal faults is west-east and southwest northeast. There are two period of uranium mineralization occurrences in the area, the first is connected with the eruption of Nyaan rhyolite magma and the second is connected with the eruption of Kawat rhyolite magma. Uranium mineralization occurred in the stage of hydrothermal process and including in the pneumatogenic class of volcanogenic uranium deposits. This investigation has yielded two sites of potential uranium sector are the Nyaan sector with an area of about 6 km2 and Kawat sector with an area of about 10 km2. (author)

  10. International Uranium Resources Evaluation Project (IUREP) national favourability studies: United Arab Emirates

    International Nuclear Information System (INIS)

    While most of the rocks in the United Arab Emirates are of sedimentary marine origin there are also some granites and metamorphic rock areas. It is understood that Hunting Geology and Geophysics Ltd were contracted in 1975 to carry out a mineral survey over 11,500 square kilometres utilising, among others, gamma-ray spectrometry. The results of this survey are not known. A report in 1974 of a large occurrence of uranium in Fujairah was later discredited but at least two radioactive anomalies are known in the country. The existence of granitic rocks and the appropriate conditions for calcareous duricrust formations may indicate some slight potential for uranium. The Speculative Potential may be in the 1000 to 10,000 tonnes uranium category. (author)

  11. Nondestructive assay technology for uranium resource evaluation. Infinite medium calculations. Final report

    International Nuclear Information System (INIS)

    A discrete ordinates transport code has been used to transport gamma rays from the decay of the naturally occurring radioactive isotopes of potassium, uranium, and thorium through an infinite homogeneous medium. Parametric studies varying the medium formation (i.e., shale and sandstone), porosity, and saturation were made to determine their effects on the calculated gamma-ray spectra. In addition, the effect on the gamma-ray spectra of trace quantities of heavy elements was studied by varying the uranium concentration in the formation from 0 to 6% by weight

    International Nuclear Information System (INIS)

    The New Hebrides consists of about 70 islands in the Southwest Pacific Ocean. The 12 largest, and main islands are volcanic cones with a few marine sediments. A manganese mining industry is presently producing but there has been no known activity in uranium exploration or mining. The area of the New Hebrides is nearly 15,000 square kilometers, and the principal industries are centered around agriculture and fishing. The uranium potential is estimated in category 1 (less than 1,000 tonnes U) (author)

  15. The actual status of uranium ore resources at Eko Remaja Sector: the need of verification of resources computation and geometrical form of mineralization zone by mining test

    International Nuclear Information System (INIS)

    Uranium ore resources calculation was done after ending all of geological work step. Estimation process of ore resources was started from evaluation drilling, continued with borehole logging. From logging, the result has presented in anomaly graphs, then was processed to determine thickness and grade value of ore. Those mineralization points were correlated one another to form mineralization zones which have direction of N 270 degree to N 285 degree with 70 degree dip to North. From Grouping the mineralization distribution, 19 mineralization planes was constructed which contain 553 ton of U3O8 measured. It is suggested that before expanding measured ore deposit area, mining test should be done first at certain mineralization planes to prove the method applied to calculate the reserve. Results form mining test could be very useful to reevaluate all the work-step done. (author); 4 refs; 2 tabs; 8 figs

  18. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Morocco. Draft

    International Nuclear Information System (INIS)

    The results of the study carried out during the IUREP Orientation Phase in Morocco permit to think that the possible reserves of uranium in this country range between 33,500 t and 89,500 t U3O8 for what concerns the known traces and the already prospected zones in the Northern provinces. If we consider the favourability criteria of certain geological contexts that have not been researched yet in the same provinces and the speculative potential of the Southern provinces that have not been prospected at all, we can reasonably estimate reserves to double. In this case, the potential in uranium for the whole Morocco could range between 70,000 and 180,000 tons. The uranium phosphate constitutes by far the most important reserves of Morocco and the Moroccan government has decided to recuperate this uranium as sub-product from phosphoric acid. The consultants of the IUREP mission have estimated that the 'geological reserves' were ranging at about 12,3 million tons of U3O8 and that the recoverable reserves could be between 7 and 10 million tons of U3O8

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Sri Lanka

    International Nuclear Information System (INIS)

    Sri Lanka is essentially a detached portion of the Deccan Plateau of south India and like it, is underlain almost everywhere by hard old Precambrian rocks. Prior to 1940 there was no systematic organised geological survey work on the island. Between 1957 and 1962 a partial aerial survey and field traverses were conducted in a search for radio- active minerals. Since then a modest programme has continued. Thorianite was first discovered in placer deposits in 1903 and prospecting has found many other refractory radioactive minerals probably derived from the weathering of pegmatites. Monazite is found as an important constituent of beach placer deposits and it is estimated to have an average content of 8-10%ThO2 and 0.3 - 0.5% U3O8. Up to 1000 tons monazite per year could be produced from the beach sand industry. Sri Lanka has had very little systematic exploration for uranium and as it is largely composed of Precambrian rocks it deserves closer attention. On the other hand it is part of a thorium rich province and there is a body of technical opinion that believes that thorium rich provinces are unlikely to contain significant uranium deposits. For these reasons it is estimated that the Speculative Potential may be within the range of 1000 to 10,000 tonnes uranium. In addition it maybe possible to produce up to 5 tonnes uranium and 100 tonnes thorium from the beach sand industry on an annual basis. (author)

    Full Text Available In the autumn of 2009 the Jagiellonian Library became the depositary of a large, valuable and interesting collection of printed books from the library of the Camaldolese Monastery in Bielany (Krakow. The work on processing the collection began almost immediately after all the prints had been taken over by the Jagiellonian Library. Two groups of employees have been involved in the work, both from the Resource Processing Department and the Antique Books Department, in line with the natural division into modern and old prints. The Camaldolese collection from Bielany has been enclosed in the monastery and unavailable to most readers; now the very books which for many years have been the source of knowledge, assistance and cognitive tools to a narrow circle of monks may be accessed by all interested persons. In the next year, after basic processing of the collection, the books will create an extremely interesting research opportunity.

  6. Radioactive and chemical contamination of the water resources in the former uranium mining and milling sites of Mailuu Suu (Kyrgyzstan)

    International Nuclear Information System (INIS)

    An assessment of the radioactive and chemical contamination of the water resources at the former uranium mines and processing sites of Mailuu-Suu, in Kyrgyzstan, was carried out. A large number of water samples were collected from the drinking water distribution system (DWDS), rivers, shallow aquifers and drainage water from the mine tailings. Radionuclides and trace metal contents in water from the DWDS were low in general, but were extremely high for Fe, Al and Mn. These elements were associated with the particle fractions in the water and strongly correlated with high turbidity levels. Overall, these results suggest that water from the DWDS does not represent a serious radiological hazard to the Mailuu Suu population. However, due to the high turbidities and contents of some elements, this water is not good quality drinking water. Water from artesian and dug wells were characterized by elevated levels of U (up to 10 μg/L) and some trace elements (e.g. As, Se, Cr, V and F) and anions (e.g. Cl−, NO3−, SO42−). In two artesian wells, the WHO guideline value of 10 μg/L for As in water was exceeded. As the artesian wells are used as a source of drinking water by a large number of households, special care should be taken in order to stay within the WHO recommended guidelines. Drainage water from the mine tailings was as expected highly contaminated with many chemicals (e.g. As) and radioactive contaminants (e.g. U). The concentrations of U were more than 200 times the WHO guideline value of 30 μg/L for U in drinking water. A large variation in 234U/238U isotopic ratios in water was observed, with values near equilibrium at the mine tailings and far from equilibrium outside this area (reaching ratios of 2.3 in the artesian well). This result highlights the potential use of this ratio as an indicator of the origin of U contamination in Mailuu Suu. - Highlights: • Chemical and radiological study of former uranium mines and processing sites. • Radioactive and

    Hong Kong is a densely populated British Colony of the southeast coast of China comprising slightly over 1000 sq. km. of area containing nearly 4-5 million people. Geologically, it has limited quantities of both source and host rocks of unknown quality, plus iron, lead and tungsten mineralization,, Mining of iron, kaolin, feldspar and quartz presently of some importance. A category 1 (0-1000 tonnes U) uranium potential is assigned. (author)

  8. Uranium production

    International Nuclear Information System (INIS)

    The alltime high for uranium concentrate production is expected to be reached in 1980. The average grade of ore fed to process will be up about 10% from last year. Some curtailments in uranium processing were announced, but three new processing plants began production in 1980. The prospects for 1981 are not as encouraging. The continuation of low prices and slow demand for U3O8 are expected to be reflected in a significant reduction in overall production and in the postponement of some plans for expansion and construction of uranium processing facilities. Increases in production capacity will occur when Plateau Resource's 750 TPD mill at Ticaboo, Utah, starts up early next year, and additional production of byproduct uranium is expected from western phosphate operations and from the southern states. These increases in capacity, however, will not offset the cutbacks in uranium processing already in force together with the additional curtailments anticipated during the course of 1981

  9. Uranium resource utilization improvements in the once-through PWR fuel cycle

    International Nuclear Information System (INIS)

    In support of the Nonproliferation Alternative Systems Assessment Program (NASAP), Combustion Engineering, Inc. performed a comprehensive analytical study of potential uranium utilization improvement options that can be backfit into existing PWRs operating on the once-through uranium fuel cycle. A large number of potential improvement options were examined as part of a preliminary survey of candidate options. The most attractive of these, from the standpoint of uranium utilization improvement, economic viability, and ease of implementation, were then selected for detailed analysis and were included in a single composite improvement case. This composite case represents an estimate of the total savings in U3O8 consumption that can be achieved in current-design PWRs by implementing improvements which can be developed and demonstrated in the near term. The improvement options which were evaluated in detail and included in the composite case were a new five-batch, extended-burnup fuel management scheme, low-leakage fuel management, modified lattice designs, axial blankets, reinsertion of initial core batches, and end-of-cycle stretchout

    1982-08-01

    A detailed geochemical test survey has been conducted in a 570 sq km area around six small copper-uranium prospects in sandstones of the Devonian Catskill Formation near Monticello in southern New York state. This report summarizes and interprets the data for about 500 stream sediment samples, 500 stream water samples, and 500 ground water samples, each analyzed for 40 to 50 elements. The groundwater samples furnish distinctive anomalies for uranium, helium, radon, and copper near the mineralized localities, but the samples must be segregated into aquifers in order to obtain continuous well-defined anomalies. Two zones of uranium-rich water (1 to 16 parts per billion) can be recognized on cross sections; the upper zone extends through the known occurrences. The anomalies in uranium and helium are strongest in the deeper parts of the aquifers and are diluted in samples from shallow wells. In stream water, copper and uranium are slightly anomalous, as in an ore factor derived from factor analysis. Ratios of copper, uranium, and zinc to conductivity improve the resolution of anomalies. In stream sediment, extractable uranium, copper, niobium, vanadium, and an ore factor furnish weak anomalies, and ratios of uranium and copper to zinc improve the definition of anomalies. The uranium/thorium ratio is not helpful. Published analyses of rock samples from the nearby stratigraphic section show distinct anomalies in the zone containing the copper-uranium occurrences. This report is being issued without the normal detailed technical and copy editing, to make the data available to the public before the end of the National Uranium Reconnaissance Evaluation program.

  15. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Saudi Arabia

    International Nuclear Information System (INIS)

    Saudi Arabia occupies most of the Arabian Peninsula and has an area of 872,722 sq miles, or 2,260,350 sq km. The ancient Arabian Shield of igneous and metamorphic rocks comprises most of the western third of the country. The shield contains many extinct volcanoes surrounded by lava beds. Sloping eastwards are the newer sedimentary areas in which rich oil fields are found. In Saudi Arabia oil is paramount and less effort has been put into searching for mineral deposits than in other countries of similar size and geology. Pour aerial radiometric surveys have been undertaken and some of the anomalies discovered in the earlier ones were ground checked by an IAEA expert in 1963-64. Two anomalies warranted more detailed work, these were the Jabal Said anomaly in the Central Shield area and the Al Ghrayyat in Wadi Sawawin about 70 miles from the Jordan border. The Jabal Said anomaly consists of a zone of altered rocks consisting largely of pegmatite and pegmatite granite= Allanite, pyrochlore, cyrtolite, xenotime and monazite are the ore minerals,, The deposit was estimated to have 2.2 million tons of ore grading 0.2 - 0.3 percent Nb2O5 and 0.03 - 0,05% U3O8. The other occurrence at Al Ghrayyat is similar but with much lower grade uranium content. In view of the huge size of Saudi Arabia, the existence of many geologically favourable rock types and the poor coverage by sophisticated uranium exploration techniques, the Speculative Potential is placed between 10,000 and 50,000 Tonnes uranium.

    International Nuclear Information System (INIS)

    Mongolia, a country of 1,525,000 square kilometers, and a population of almost the same number of people is land locked between China and USSR. Historically it's closest ties have been with China, but it is now more closely associated with USSR. Geologically it's complex - most exposed formations are younger than PreCambrian although old exist. Potential for uranium is considered fairly good because the fairly complex geology appears to be favourable both for continental sandstone type deposits and calcretes (less than 50%) and vein type, and other deposits (more than 50$). Considerable effort should be made to obtain additional information related to Mongolian geology. (author)

    International Nuclear Information System (INIS)

    In the first years of the uranium program, starting in 1948, drilling was primarily undertaken by the government. The AEC and the U.S. Geological Survey continued a modest program until the mid-1950's. The government drilled about 5-6 million feet (1.7 million meters), and a number of significant ore deposits were defined, primarily in the Uravan Mineral Belt, Colorado. Except for the early years, private drilling exceeded the government program. Drilling reached a peak of 2.8 million meters in 1957, but dropped back to 0.6 million meters in 1965 when the government purchase program had been phased out. Later, with resurgence of uranium demand it rose again to nearly 9.1 million meters in 1969. After a decline in the early 1970's, activity rose dramatically to 10.3 million meters in 1976. Total drilling through 1976 has been about 88.3 million meters. Exploration costs from 1966 through 1976 are estimated to be $679 million. During 1976, 32 percent of the drilling or 3.3 million meters was in the Wyoming Basins, with 4.5 million meters or 43 percent in the Colorado Plateau, and 0.9 million meters or 8 percent in the Gulf Coastal Plain. Total 1976 drilling was 0.9 million meters and average depth of hole 155 meters; this contrasts with 1.7 million meters and 53 meters average depth in 1960. Reserves of uranium are located in the western portion of the country with over 85 percent in the Colorado Plateau and Wyoming Basins. The Basin and Range province of Oregon, California, Nevada, Arizona, New Mexico, and Texas is receiving considerable exploration emphasis. Other areas of increasing activity include sedimentary rocks of the Great Plains and the crystalline rocks of the Rocky Mountains, Appalachian Mountains, and the Precambrian shield of Michigan and Wisconsin. Work in the new areas emphasizes geologic and geophysical assessment, so relatively little drilling has been done. When programs have matured, it is assumed that drilling effort will be accelerated

    International Nuclear Information System (INIS)

    French Polynesia comprises several district groups of islands in the South Pacific having a total population of 134,000 and an area of 5000 square kilometers. The high islands are commonly volcanic in origin while the lower islands are generally coral. They lie in the Tropic zone and are generally warm. Rainfall ranges from a few centimeters per year to as much as 1000. Because of their volcanic or coral origins, the islands of French Polynesia are not considered to have a uranium potential.

Generally speaking, there are favorable conditions for uraniummineralization and good perspective to explore for uranium resources.

  1. Preliminary mining assessment of the uranium resource at Kvanefjeld, the Ilimaussaq Intrusion, South Greenland

    International Nuclear Information System (INIS)

    This study of the Kvanefjeld uranium deposit was commissioned by the Danish Ministry of Energy in 1981 and was carried out by the Risoe National Laboratory. The purpose of this report is to record the current state of knowledge of geology of the deposit, to estimate the scale and average uranium grade of the material which can be fed to the mill from the deposit, to develop a mining plan for the mineralized zone, to indicate possible by-products and to suggest any further investigations which will be required before the project is brought into production. It is recommended that some further limited preproduction field work should be undertaken. Such field work should include geological re-mapping, in-fill drilling of the mineralized zones and underground diamond drilling to test the grade of the deposit at depth and rock-mechanical investigations. These studies are necessary to give detailed data on the mineralized material planned to be mined and processed during the initial 5 years of production. It is estimated that the cost of pre-production activity will be about D.Kr. 10.0 million and that the programme could be completed in about 1 year. (author)

  4. Changes and events in uranium deposit development, exploration, resources, production and the world supply-demand relationship. Proceedings of a technical committee meeting

    International Nuclear Information System (INIS)

    This report consists of the proceedings of the Technical Committee Meeting on Recent Changes and Events in Uranium Deposit Development, Exploration, Resources, Production and the World Supply/Demand Relationship, held in co-operation with the OECD Nuclear Energy Agency (OECD/NEA) in Kiev, Ukraine, from 22 to 26 May 1995. Some of the information from this meeting was also used in preparation of the 1995 edition of ''Uranium - Resources, Production and Demand'' a joint report by the OECD/NEA and the IAEA. At the Beginning of 1995 there were 432 nuclear power plants in operation with a combined electricity generating capacity of 340 GW(e). This represents nearly a 100% increase over the last decade. In 1995 over 2228 TW·h of electricity were generated, equivalent to about 17% of the world's total electricity. To achieve this, about 61,000 t U were required as nuclear fuel. For about a decade and a half uranium production and related activities have been decreasing because of declining uranium prices. For many participants in the nuclear industry there has been little interest in uranium supply because of the oversupplied market condition. The declining production led to the development of a supply and demand balance were production is currently meeting a little over 50% of reactor requirements and the excess inventory is being rapidly drawn down. This very unstable relationship has resulted in great uncertainty about the future supply or uranium. One of the objectives of this Technical Committee meeting was to bring together specialists in the field of uranium supply and demand to collect information on new developments. This helps provide a better understanding of the current situation, as well as providing information to plan for the future. Refs, figs, tabs

  5. Geostatistics project of the national uranium resource evaluation program. Progress report, April 1981-September 1981

    International Nuclear Information System (INIS)

    During the period covered by this report, we proposed a method of comparing aerial and ground data as a means of assessing the quality of aerial data. We also compared two methods of partitioning count rates among several isotopes. Time-series analysis and analysis of variance were considered as tools for using aerial radiometric data to aid in designing ground-based sampling experiments. Several methods of computing covariance matrices were compared for use with very large data sets. A study showed a potential for using aerial radiometric data to rank quadrangles according to the Department of Energy's estimated uranium inventories. A discriminant analysis code was transferred to Grand Junction, and several statistics short courses were presented there. Recommended cluster analysis procedures were developed and applied to aerial radiometric data. Reports and papers were prepared on topics such as outlier detection, percentile estimation, discriminant analysis, and statistical package comparison

    The uranium-vanadium deposits of the Salt Wash Member of the Morrison Formation in the Colorado Plateau are similar to sandstone uranium deposits elsewhere in the USA. The differences between Salt Wash deposits and other sandstone uranium deposits are also significant. The Salt Wash deposits are unique among sandstone deposits in that they are dominantly vanadium deposits with accessory uranium. The Salt Wash ores generally occur entirely within reduced sandstone, without adjacent tongues of oxidized sandstone. They are more like the deposits of Grants, which similarly occur in reduced sandstones. Recent studies of the Grants deposits have identified alteration assemblages which are asymmetrically distributed about the deposits and provide a basis for a genetic model for those deposits. The alteration types recognized by Shawe in the Slick Rock district may provide similar constraints on ore formation when expanded to broader areas and more complete chemical analyses.

  9. Model for water factor measurements with fission-neutron logging tools. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    During 1977 and 1978, a Fission Neutron Water Factor Model was designed and constructed by Bendix Field Engineering Corporation (BFEC) for the United States Department of Energy (DOE) at the Grand Junction facility. This model features seven water-filled boreholes with different diameters. All of these boreholes penetrate, in order from the top of the model, a 5-foot-thick (1.52 m), uniform, concrete upper ''barren zone''; a 6-foot-thick (1.83 m), uniform, uranium-enriched, concrete ''ore zone''; and a 4-foot-thick (1.22 m), uniform, concrete lower ''barren zone''. The response of a fission neutron logging tool in a water-filled borehole is affected by variations in the borehole diameter. This diameter-dependent effect can be deduced from logs run in several different boreholes of the Fission Neutron Water Factor Model. This report describes the construction of the Fission Neutron Water Factor Model and also presents values for model parameters which are of interest in fission-neutron logging

  11. Recent developments in uranium resources and supply. Proceedings of a technical committee meeting held in Vienna, 24-28 May 1993

    International Nuclear Information System (INIS)

    In recent years substantial uncertainties regarding uranium supply have made it very difficult for both uranium producers and users to plan for the future. In 1992 uranium production met only about 63 percent of reactor requirements. This resulted in a very unstable supply/demand balance where inventory drawdown (supplemented by minor amounts of reprocessing) filled the 20,960 tonne shortfall. The IAEA convened this Technical Committee meeting to take advantage of the new opportunities to collect and analyse information related to the future supply and demand balance and to help reduce uncertainties regarding the relationship. The meeting was effective in bringing together experts from all regions to share, exchange and disseminate information regarding uranium related activities. This meeting on Recent Developments in Uranium Resources and Supply was held in Vienna from 24 to 26 May 1993. It was attended by 47 participants from 23 countries. Twenty-one papers were presented. Contributions from China, the Czech Republic, India, Kazakhstan, Mongolia, Romania and the Russian Federation represent new information in this field. Refs, figs and tabs

    Full Text Available All of the reviewed books in this edition are relevant to an international dialogue between educational and health domains. Together they address a cluster of related themes relevant to teachers and parents, as well as to many other professionals workingwith children and young people. These themes include Social, Emotional and Behavioural Disorders (SEBD, Attachment Patterns at preschool and primary level, Anger expression and management, as well as individual differences in sensory processing. Cooper and Jacobs’ book offers a panoramic view of evidence to inform which approaches to promoting the educational engagement of students with SEBD, are most promising, with distinctive arguments therein in relation to labelling and interprofessional collaboration. Golding and her colleagues offer accounts of observational tools as resources for preschool and primary teachers, respectively, to identify attachment difficulties in children. This raises a myriad of issues for exploration. Irving Henry and her colleagues offer a resource for teachers and parents on anger, mainly within a cognitive-behavioural frame of reference. O’Connor identifies a range of theoretically informed, practical strategies for improving children’s concentration and learning through sensory processing. A common theme across most of these books is the need to go beyond a ‘one size fits all’ approach to more differentiated, interdisciplinary strategies for meeting children’s complex array of needs.

  14. National Uranium Resource Evaluation Program. Hydrogeochemical and stream sediment reconnaissance basic data for Green Bay NTMS Quadrangle, Wisconsin

    International Nuclear Information System (INIS)

    Field and laboratory data are presented for 695 groundwater samples, 546 stream sediment samples, and 401 stream water samples. Statistical and areal distributions of uranium and other possibly uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Greater than 85th percentile concentrations of uranium in all sample types define an area of about 2,000 km2 (780 mi2) in the central and north central portions of the survey area as the most probable area for potential uranium mineralization within the quadrangle. Bedrock of the area includes granitic and monzonitic batholiths of Precambrian age. A 500 km2 area is also outlined by uranium in groundwater samples coincident with a Precambrian fault-shear zone in Marathon County. Anomalous uranium concentrations occur in stream sediments from Marathon, Wood, and Portage Counties; however, other associated variables suggest that the uranium is associated with refractory minerals which are less favorable for commercial potential. Concentrations of uranium above the 85th percentile are also found in Waushara, Winnebago, Outagamie, and Shawano Counties within the area of Cambrian sandstone and Prairie du Chien outcrop. Groundwater and stream water representing the Sinnipee and Ancell Rock Groups, and the Richmond and Silurian Formations are characterized by high conductivity, calcium, magnesium, sulfate, total alkalinity, and pH, but moderate to low concentrations of uranium

  15. Uranium Provinces in China

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-lnner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted in the formation of Phanerozoic hydrothermal uranium deposits under extensional tectonic environments. Erosion of uraniferous rocks and pre-existing uranium deposits during the Meso-Cenozoic brought about the removal of uranium into young sedimentary basins. When those basins were uplifted and slightly deformed by later tectonic activity, roll-type uranium deposits were formed as a result of redox in permeable sandstone strata.

  20. Perspective and resource evaluation and metallogenic studies on sandstone-type uranium deposit in Qianjiadian depression of Songliao Basin

    International Nuclear Information System (INIS)

    The geotectonic evolution history of the southeastern part of Songliao Basin has been clearly described and it is pointed out that both of the provenance rocks and evolution features of the studied area are favorable to the formation of U-rich sandstone bodies, development of interlayered oxidation and providing uranium source for mineralization. Yaojia Formation in Qianjiadian depression has been found out to be the favorable target ore bed for looking for sandstone-type uranium deposit. On the basis of analysis of metallogenetic conditions, the perspective target area has been circled and a sandstone-type uranium deposit with a certain amounts of uranium tonnages has been discovered. The achievements and data have been gotten in the following aspects: constitution and features of ore-forming beds and sandstone bodies, uranium existence forms and mineralogical and chemical compositions of the ores, associated elements and their economic values for comprehensive mining. The study of metallogenetic features and mechanism of the uranium deposit suggested that pre-enrichment of uranium during the depositional-diagenetic stage provide a good basis for uranium mineralization, and hereafter interlayered oxidation as well as oil-gas reduction processes played a decisive role to uranium mineralization. U-Pb isotopic studies indicate that the ores have two isochron ages of 53±3 Ma and 7.0±0 Ma, corresponding to the periods of arid and semiarid paleo-climates which are favorable to interlayered oxidation development and uranium mineralization. It is concluded that the Qianjiadian sandstone-type uranium deposit is genetically related to interlayered oxidation and secondary reduction of oil-gas. The metallogenic model of Qianjiadian uranium deposit was set up. (authors)

  1. Application of Kriging to hydrogeochemical data from the National Uranium Resource Evaluation Program

    International Nuclear Information System (INIS)

    The Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) Program is an important part of the data collection segment of the NURE Program. This report presents the preliminary results of applying a new geostatistical tool, known as Kriging, to HSSR data from the Plainview Quadrangle in Texas. The essential conclusion of this report is that Kriging can be useful in characterizing geochemical data and identification of the anomalous geographic regions used in resource appraisal. Computer codes were prepared for use either on other variables or stream sediment data and/or data from other quadrangles. Several ways of using Kriging to enhance HSSR data for the purpose of identifying favorable areas were identified

  2. Uranium Market

    International Nuclear Information System (INIS)

    The main fuel component for commercial nuclear power reactors is Uranium. When compared to fossil fuels, it has a competitive edge due to factors such as economics and environmental conditions and in particular due to its international market availability. Uranium world demand reached to 67 320 tU in 2004, which was covered with additional sources. To project the uranium markets behavior requires to know and to accept some conditions tied to the demand, such as the electrical world consumption, the greenhouse effect; water desalination, production of hydrogen, industrial heat, the innovative development of nuclear reactors, and the average time of 10 years between the beginning of exploration programs and definition of deposits, which it owes mainly to the difficulty of achieving the legal, environmental and local community authorizations, to open new mining centers. Uranium market future projections, made by IAEA experts in 2001, that considered middle and high demand scenarios, concluded that cumulatively to year 2050, with regard to demand it will be required 5.4 and 7.6 million tons of uranium respectively, and with regard to the uranium price, it should present a sustained increase. In the last years the situation of the uranium market has changed dramatically. In August 2006 the price of uranium reached to USD 106/kgU in the spot market, surpassing all the made projections. The increase in price that has stayed in rise in the last five years is reactivating the prospection and exploration efforts anywhere in the world, and competition between prospective areas of potential resources mainly in less explored territories

    The National Uranium Resource Evaluation (NURE) program was initiated in 1973 with a primary goal of identifying uranium resources in the United States. The airborne program's main purpose was to collect radiometric data of the conterminous United States and Alaska. Magnetic data were also collected. After the program ended, most of the data were given to the U.S. Geological Survey (USGS). All areas were flown at about 400 feet above ground, the optimum height for collecting radiometric data, and the line spacing varied from 3 to 6 mile intervals. A few selected quadrangles or parts of quadrangles were flown at 1- or 2-mile line spacing. About forty smaller areas were targeted and flown at 0.25-mile to 1 mile line spacing.

  4. Book Review: Book review

    2015-02-01

    The subject of the theory of vibrations has carried an aesthetic appeal to generations of engineering students for its richness of ideas, and for the intellectual challenges it offers. Also, the diverse range of its applications (covering civil, mechanical, automotive, and aerospace structures) has provided obvious motivations for its study. For most students, the subject provides, perhaps, the first encounter in substantial application of mathematical tools (differential equations, calculus of variations, Fourier/Laplace transforms, and matrix algebra) to engineering problems. The intimate relationship that the subject of mechanics has with mathematics strikes home probably for the first time. While teaching this subject, the instructor is spoilt for choice in selecting a text book and so are the students who wish to pursue a self-study of the subject. Many luminaries in the field have offered their own exposition of the subject: starting from the classics of Rayleigh, Timoshenko, Den Hartog, Bishop and Johnson, and the works of more recent vintage (e.g., the books by Meirovich, Clough, and Penzien, and works with computational flavour, such as, those by Bathe and Petyt), several works easily come to one's mind. Given this milieu, it requires a distinctive conviction to write a new book on this subject. And, here we have a book, written by a practitioner, which aims to deal with fundamental aspects of vibrations of engineering systems. The scepticism that this reviewer had on the need for having one more such book vanished as he browsed through the book and read selectively a few sections. The author's gift for elegant explanations is immediately noticeable even in such a preliminary reading. After a more careful reading, the reviewer has found this book to be insightful and he considers the book to be a welcome addition to the family of books on vibration engineering. The author has struck a fine balance between physical explanations, mathematical niceties

    1978-09-29

    Field and laboratory data are presented for 718 groundwater and 715 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwater data indicate that uranium concentrations above the 85th percentile are predominant in the Trinity Group (Lower Cretaceous), and the Taylor and Navarro Groups (Upper Cretaceous). Values of uranium above the 85th percentile also occur in the Permian units located in the northwestern section of the survey area. Several trends delineating saline water are discernable, the most notable of which occur in sections of the Woodbine Formation and the Permian units. Less distinguishing saline trends occur in many of the Upper Cretaceous formations. Stream sediment data indicate that uranium concentrations above the 85th percentile occur in sections of the Fredericksburg Group parallel to the contact with the Washita Group, in the Eagle Ford Formation, and in the Taylor Group. High values of uranium in the Fredericksburg Group appear to be associated with carbonates and marine clays. High values of uranium in the Eagle Ford Formation are most likely associated with heavy and/or resistate mineral assemblages. High values of uranium occurring in the Taylor Group may be related to the carbonate and phosphatic lithologies which comprise this group.

  6. A guide to the lower limit - combination of size and grade - of deposits of interest for uranium resources

    International Nuclear Information System (INIS)

    An attempt has been made to establish a method of classifying in broad terms low-tonnage/low-grade uranium resources in terms of size, recovery grade and gross sales revenue at various price levels. To arrive at a basis for discussion, the following assumptions are made: (i) An overall average U3O8 recovery grade of less than 50 g/t will never constitute a viable proposition; (ii) That no deposit, or cluster of deposits, containing less than 500,000 t ore will constitute a viable deposit; and (iii) Revenue requirements would vary according to the needs of the producer. It is, however, suggested that a gross sales revenue of US $50,000,000 over the life of the mine (10 years) is regarded as an absolute minimum requirement for viability. From these data a family of curves has been constructed using a tonnage/grade combination which gives a gross revenue of US $50,000,000 for various price categories in terms of $/kg U. These curves may then be used to categorize deposits and to ascertain whether they are likely to constitute a viable proposition within the constraints listed above. (author)

  7. Neutron activation and other analytical data for plutonic rocks from North America and Africa. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    The objective of this report is to retrieve the elements of an analytical study of granites and associated other plutonic rocks which was begun as a part of the U.S. Department of Energy's National Uranium Resource Evaluation (NURE) program. A discussion of the Savannah River Laboratory (SRL) neutron activation analysis system is given so that a user will understand the linmitations of the data. Enough information is given so that an experienced geochemist can clean up the data set to the extent required by any project. The data are generally good as they are presented. It is intended that the data be read from a magnetic tape written to accompany this report. Microfiche tables of the data follow the text. These tables were prepared from data on the tape, and programs which will read the tape are presented in the section THE DATA TAPE. It is our intent to write a later paper which will include a thoroughly scrubbed data set and a technical discussion of results of the study. 1 figure

    Four major types of uranium deposits occur in China: granite, volcanic, sandstone, and carbonaceous-siliceous-pelitic rock. These types are major sources of uranium in many parts of the world and account for about 95 percent of Chinese production. Descriptive models for each of these types record the diagnostic regional and local geologic features of the deposits that are important to genetic studies, exploration, and resource assessment. A fifth type of uranium deposit, metasomatite, is also modeled because of its high potential for production. These five types of uranium deposits occur irregularly in five tectonic provinces distributed from the northwest through central to southern China. ?? 1993 Oxford University Press.

  10. National Uranium Resource Evaluation Program. Hydrogeochemical and stream sediment reconnaissance basic data for Lemmon NTMS Quadrangle, South Dakota

    International Nuclear Information System (INIS)

    Results are reported of a reconnaissance geochemical survey of the Lemmon Quadrangle, South Dakota. Field and laboratory data are presented for 565 groundwater and 531 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors are briefly discussed which may be of significance in evaluating the potential for uranium mineralization. The groundwater data indicate that the area which appears most promising for uranium mineralization is located in the southwestern portion of the quadrangle. Groundwater in this area is produced primarily from the Cretaceous Fox Hills Formation where high values were determined for uranium, arsenic, potassium, and silicon and low values for boron, sodium, pH, sulfate, specific conductance, and total alkalinity. The presence of Tertiary ash deposits and the abundance of organics downdip in the permeable Fox Hills Formation could provide a suitable geochemical framework for uranium accumulation. The stream sediment data indicate that the Pierre Shale, Fox Hills, and Hell Creek Formations in the southwestern portion of the quadrangle have the highest potential for uranium mineralization. Sediments derived from these units are high in uranium, aluminum, arsenic, chromium, cobalt, copper, lithium, magnesium, niobium, nickel, phosphorous, scandium, vanadium, yttrium, zinc, and zirconium

    Results of a reconnaissance geochemical survey of the Manhattan Quadrangle, Kansas, are reported. Field and laboratory data are presented for 674 groundwater and 718 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. The groundwater data indicate that the most promising area for potential uranium mineralization occurs in the western-northwestern part of the quadrangle where waters are produced from the Quaternary loess deposits, and the Cretaceous Greenhorn-Graneros and Dakota Formations. Associated elements in the quadrangle include arsenic, potassium, manganese, vanadium, and selenium. The stream sediment data indicate that the highest average uranium concentrations in sediments from the Manhattan Quadrangle are obtained from the Pennsylvanian Wabaunsee Group followed by the Cretaceous Carlile Shale, Greenhorn-Graneros and Dakota Formations. In the northwestern corner of the quadrangle, high concentrations of uranium are associated with high concentrations of barium, niobium, strontium, titanium, vanadium, yttrium, and zirconium. In southeast Cloud County and extending to the northeast, high values of total uranium are associated with high values of titanium, yttrium, zirconium, and low U-FL/U-NT values. These associations indicate that the uranium is probably present in heavy and/or resistate minerals.

  12. Uranium in Canada

    International Nuclear Information System (INIS)

    In 1974 the Minister of Energy, Mines and Resources (EMR) established a Uranium Resource Appraisal Group (URAG) within EMR to audit annually Canada's uranium resources for the purpose of implementing the federal government's uranium export policy. A major objective of this policy was to ensure that Canadian uranium supplies would be sufficient to meet the needs of Canada's nuclear power program. As projections of installed nuclear power growth in Canada over the long term have been successively revised downwards (the concern about domestic security of supply is less relevant now than it was 10 years ago) and as Canadian uranium supply capabilities have expanded significantly. Canada has maintained its status as the western world's leading exporter of uranium and has become the world's leading producer. Domestic uranium resource estimates have increased to 551 000 tonnes U recoverable from mineable ore since URAG completed its last formal assessment (1982). In 1984, Canada's five primary uranium producers employed some 5800 people at their mining and milling operations, and produced concentrates containing some 11 170 tU. It is evident from URAG's 1984 assessment that Canada's known uranium resources, recoverable at uranium prices of $150/kg U or less, are more than sufficient to meet the 30-year fuelling requirements of those reactors that are either in opertaion now or committed or expected to be in-service by 1995. A substantial portion of Canada's identified uranium resources, recoverable within the same price range, is thus surplus to Canadian needs and available for export. Sales worth close to $1 billion annually are assured. Uranium exploration expenditures in Canada in 1983 and 1984 were an estimated $41 million and $35 million, respectively, down markedly from the $128 million reported for 1980. Exploration drilling and surface development drilling in 1983 and 1984 were reported to be 153 000 m and 197 000 m, respectively, some 85% of which was in

  13. Research of natural resources saving by design studies of Pressurized Light Water Reactors and High Conversion PWR cores with mixed oxide fuels composed of thorium/uranium/plutonium

    International Nuclear Information System (INIS)

    Within the framework of innovative neutronic conception of Pressurized Light Water Reactors (PWR) of 3. generation, saving of natural resources is of paramount importance for sustainable nuclear energy production. This study consists in the one hand to design high Conversion Reactors exploiting mixed oxide fuels composed of thorium/uranium/plutonium, and in the other hand, to elaborate multi-recycling strategies of both plutonium and 233U, in order to maximize natural resources economy. This study has two main objectives: first the design of High Conversion PWR (HCPWR) with mixed oxide fuels composed of thorium/uranium/plutonium, and secondly the setting up of multi-recycling strategies of both plutonium and 233U, to better natural resources economy. The approach took place in four stages. Two ways of introducing thorium into PWR have been identified: the first is with low moderator to fuel volume ratios (MR) and ThPuO2 fuel, and the second is with standard or high MR and ThUO2 fuel. The first way led to the design of under-moderated HCPWR following the criteria of high 233U production and low plutonium consumption. This second step came up with two specific concepts, from which multi-recycling strategies have been elaborated. The exclusive production and recycling of 233U inside HCPWR limits the annual economy of natural uranium to approximately 30%. It was brought to light that the strong need in plutonium in the HCPWR dedicated to 233U production is the limiting factor. That is why it was eventually proposed to study how the production of 233U within PWR (with standard MR), from 2020. It was shown that the anticipated production of 233U in dedicated PWR relaxes the constraint on plutonium inventories and favours the transition toward a symbiotic reactor fleet composed of both PWR and HCPWR loaded with thorium fuel. This strategy is more adapted and leads to an annual economy of natural uranium of about 65%. (author)

  14. Uranium mining

    International Nuclear Information System (INIS)

    Full text: The economic and environmental sustainability of uranium mining has been analysed by Monash University researcher Dr Gavin Mudd in a paper that challenges the perception that uranium mining is an 'infinite quality source' that provides solutions to the world's demand for energy. Dr Mudd says information on the uranium industry touted by politicians and mining companies is not necessarily inaccurate, but it does not tell the whole story, being often just an average snapshot of the costs of uranium mining today without reflecting the escalating costs associated with the process in years to come. 'From a sustainability perspective, it is critical to evaluate accurately the true lifecycle costs of all forms of electricity production, especially with respect to greenhouse emissions, ' he says. 'For nuclear power, a significant proportion of greenhouse emissions are derived from the fuel supply, including uranium mining, milling, enrichment and fuel manufacture.' Dr Mudd found that financial and environmental costs escalate dramatically as the uranium ore is used. The deeper the mining process required to extract the ore, the higher the cost for mining companies, the greater the impact on the environment and the more resources needed to obtain the product. It is clear that there is a strong sensitivity of energy and water consumption and greenhouse emissions to ore grade, and that ore grades are likely to continue to decline gradually in the medium to long term. These issues are critical to the current debate over nuclear power and greenhouse emissions, especially with respect to ascribing sustainability to such activities as uranium mining and milling. For example, mining at Roxby Downs is responsible for the emission of over one million tonnes of greenhouse gases per year and this could increase to four million tonnes if the mine is expanded.'

    International Nuclear Information System (INIS)

    Field and laboratory data are presented for 734 groundwater and 659 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors for uranium mineralization are briefly discussed. Groundwater data indicate high concentrations of uranium along several northeast--southwest trends paralleling the stike of major formations cropping out within the survey area. A well-defined trend occurs in the Whitsett, Catahoula, Oakville, and Fleming Formations. Another prominent trend is present along the Taylor, Navarro and Midway Groups; the uranium anomalies there are associated with bedded phosphates. Several trends delineating saline water are also discernible, the most prominent of which occurs in the Lower Jackson Group and Yegua Formation. Other saline water trends occur in the Fredericksburg and Trinity Groups in the northwest section of the survey area. The stream sediment data indicate that uranium is associated with heavy and/or resistate minerals in the Wilcox Group and the Whitsett--Catahoula and Oakville--Fleming Formations. The relatively high percentage of detrital minerals in these units reflects the proximity of the survey area to the Llano Uplift and Edwards Plateau. Soluble uranium is primarily associated with the Eagle--Ford, Taylor, and Navarro Groups

  17. Foreign uranium supply

    International Nuclear Information System (INIS)

    Known foreign uranium resources are concentrated in a few countries. The resources of many countries are largely unassessed, but the known uranium countries appear to have the best potential for future expansion. Availability of supply from known resources will depend on resolution of national policies regarding uranium production, ownership and export, and actions of the mining industry. Foreign uranium demand projections have decreased markedly in the last few years, and currently planned and attainable production should be adequate through the 1980's. Longer term resources and supply outlook are still a major concern to both those planning electric supply systems based on converter reactors and those considering reprocessing and recycle of uranium and plutonium and development of breeder reactors. Work continues to clarify long-term supply in several countries and internationally, but more effort, and time, will be needed to clarify these issues

  20. NURE [National Uranium Resource Evaluation] HSSR [Hydrogeochemical and Stream Sediment Reconnaissance] Introduction to Data Files, United States: Volume 1

    International Nuclear Information System (INIS)

    One product of the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program, a component of the National Uranium Resource Evaluation (NURE), is a data-base of interest to scientists and professionals in the academic, business, industrial, and governmental communities. This database contains individual records for water and sediment samples taken during the reconnaissance survey of the entire United States, excluding Hawaii. The purpose of this report is to describe the NURE HSSR data by highlighting its key characteristics and providing user guides to the data. A companion report, ''A Technical History of the NURE HSSR Program,'' summarizes those aspects of the HSSR Program which are likely to be important in helping users understand the database. Each record on the database contains varying information on general field or site characteristics and analytical results for elemental concentrations in the sample; the database is potentially valuable for describing the geochemistry of specified locations and addressing issues or questions in other areas such as water quality, geoexploration, and hydrologic studies. This report is organized in twelve volumes. This first volume presents a brief history of the NURE HSSR program, a description of the data files produced by ISP, a Users' Dictionary for the Analysis File and graphs showing the distribution of elemental concentrations for sediments at the US level. Volumes 2 through 12 are comprised of Data Summary Tables displaying the percentile distribution of the elemental concentrations on the file. Volume 2 contains data for the individual states. Volumes 3 through 12 contain data for the 10 x 20 quadrangles, organized into eleven regional files; the data for the two regional files for Alaska (North and South) are bound together as Volume 12

  1. Sustainability of the Chinese nuclear expansion: Natural uranium resources availability, Pu cycle, fuel utilization efficiency and spent fuel management

    International Nuclear Information System (INIS)

    Highlights: • We simulated 4 different future nuclear fuel cycle scenarios. • The ADS and FRs impact on the future Chinese nuclear fuel cycle is studied. • The partition and transmutation option is compared against the simple reprocessing. • The U requirement, Pu flow and MA cycle are key aspects for decision makers. - Abstract: The civil nuclear energy deployment in China is important for future “Nuclear Renaissance” of China and worldwide. Compared to the other nations that developed their nuclear power energy system in last century, China can take advantage of the research and mistakes made by those states in relation to the back-end of the nuclear fuel cycle (NFC). The spent fuel accumulated by decades of operations of civil nuclear power is today a big burden for the industry. China must carefully plan the NFC for a sustainable development of the nuclear energy with special consideration to close the fuel cycle. The present paper addresses the NFC options and implications of a LWR scenario development and of a fast reactor park developed after 2035 and 2050, and covers the historical development of nuclear energy in China (i.e. from the first criticality of the first reactor) to the year 2100. The paper studies the partition and transmutation strategy with the use of accelerator driven system (ADS) to burn the minor actinides (MA) to understand the ADS impact on the NFC and to estimate the number and the necessary deploying schedule of the ADS reactors to limit the minor actinides stock build up. The other aspects taken into consideration for the comparison of the different scenarios are the natural uranium resourced used, the efficiency of fuel utilization, the proliferation and diversion risks associated to each scenario and the overall spent fuel production and flow. The code INFCIS developed by the International Atomic Energy Agency (IAEA) is used in the present study

    For many years a good introductory book for undergraduate and postgraduate students on remote sensing of the Earth's land surface, which was not starting with an emphasis on traditional photographic techniques, was missing. In 2010 the first edition of the book Fundamentals of Satellite Remote Sensing by Emilio Chuvieco and Alfredo Huete was published by CRC Press and it was filling this gap. Now the second edition by Emilio Chuvieco was published by CRC Press. This second edition is made more attractive by the use of colour and including colour illustrations instead of the black-and-white ones in the first edition.

    The National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program produced a large amount of geochemical data. To fully understand how these data were generated, it is recommended that you read the History of NURE HSSR Program for a summary of the entire program. By the time the NURE program had ended, the HSSR data consisted of 894 separate data files stored with 47 different formats. Many files contained duplication of data found in other files. The University of Oklahoma's Information Systems Programs of the Energy Resources Institute (ISP) was contracted by the Department of Energy to enhance the accessibility and usefulness of the NURE HSSR data. ISP created a single standard-format master file to replace the 894 original files. ISP converted 817 of the 894 original files before its funding apparently ran out. The ISP-reformatted NURE data files have been released by the USGS on CD-ROM (Lower 48 States, Hoffman and Buttleman, 1994; Alaska, Hoffman and Buttleman, 1996). A description of each NURE database field, derived from a draft NURE HSSR data format manual (unpubl. commun., Stan Moll, ISP, Oct 7, 1988), was included in a readme file on each CD-ROM. That original manual was incomplete and assumed that the reformatting process had gone to completion. A lot of vital information was not included. Efforts to correct that manual and the NURE data revealed a large number of problems and missing data. As a result of the frustrating process of cleaning and re-cleaning data from the ISP-reformatted NURE files, a new NURE HSSR data format was developed. This work represents a totally new attempt to reformat the original NURE files into 2 consistent database structures; one for water samples and a second for sediment samples, on a quadrangle by quadrangle basis, from the original NURE files. Although this USGS-reformatted NURE HSSR data format is different than that created by the ISP, many of their ideas were

  5. Theoretical and practical aspects of uranium geology

    International Nuclear Information System (INIS)

    The energy requirements of the future will be met increasingly from nuclear sources at least for the next few decades. This means the discovery of substantial new reserves and resources of uranium which, in the past, have been found mainly on the basis of geological knowledge. New concepts to enhance those built up over a century are urgently required to guide future exploration. These can best be established by interchange between fundamental and applied geologists and by the build-up reliable quantitative data relating to uranium distribution. An international meeting was held at the Royal Society in December 1977, contributions to which have been produced in this book. It is hoped that the initiative taken will stimulate further dialogue on a world-wide basis

    The use of geospatial data for a wide variety of applications has increased continuously over the last decades and a great variety of packages of open source GIS software are now available, with diverse characteristics. R was created as free software mainly for statistical computation and graphics, but offers now a large diversity of packages to process and visualize spatial data. Many books dedicated to R are available (e.g., Zuur et al., 2009; Chambers, 2008), but not many about spatial analysis in R (Bivand et al., 2008). The book under analysis is aimed for beginners both in R and in spatial analysis, and therefore can be used as a starting point for students and professionals which may want to enter the area of spatial analysis with R.

    Compiling a good book on urban remote sensing is probably as hard as the research in this disciplinary field itself. Urban areas comprise various environments and show high heterogeneity in many respects, they are highly dynamic in time and space and at the same time of greatest influence on connected and even tele-connected regions due to their great economic importance. Urban remote sensing is therefore of great importance, yet as manifold as its study area: mapping urban areas (or sub-categories thereof) plays an important (and challenging) role in land use and land cover (change) monitoring; the analysis of urban green and forests is by itself a specialization of ecological remote sensing; urban climatology asks for spatially and temporally highly resolved remote sensing products; the detection of artificial objects is not only a common and important remote sensing application but also a typical benchmark for image analysis techniques, etc. Urban analyses are performed with all available spaceborne sensor types and at the same time they are one of the most relevant fields for airborne remote sensing. Several books on urban remote sensing have been published during the past 10 years, each taking a different perspective. The book Global Urban Monitoring and Assessment through Earth Observation is motivated by the objectives of the Global Urban Observation and Information Task (SB-04) in the GEOSS (Global Earth Observation System of Systems) 2012-2015 workplan (compare Chapter 2) and wants to highlight the global aspects of state-of-the-art urban remote sensing.

  8. Survey of US and total world production, proved reserves, and remaining recoverable resources of fossil fuels and uranium, as of December 31, 1978

    International Nuclear Information System (INIS)

    IGT presents updated estimates (as of year-end 1978) for US and world proved reserves, remaining recoverable resources, annual production rates, and cumulative production of the non-renewable energy sources: coal, natural gas, crude oil, natural gas liquids, syncrude from oil shale and tar sands, and uranium oxide. Life expectancies are also presented for the world's fossil fuels, assuming various annual growth rates of energy consumption. Proved and currently recoverable natural gas reserves amount to 200 trillion CF in the US and 2329-2594 TCF worldwide; the total remaining recoverable, however, could be as high as 1219 TCF in the US and 9200 TCF worldwide

Life expectancies are also included for the world's fossil fuels, assuming various annual growth rates of energy consumption. Proved and currently recoverable natural gas reserves amount to 207 trillion CF in the US and 2180-2521 TCF world-wide; the total remaining recoverable, however, could be as high as 1153 TCF in the US and 8590 TCF worldwide

  10. Geological-economic analysis on the exploration of backup resources for depleted mines in Lujing uranium ore-field, central-southern China

    International Nuclear Information System (INIS)

    With the geological-economic evaluation program for pithead heap-leaching mining uranium deposits developed by the authors and the data of column-leaching tests and the geological reserve, the geological-economic evaluation is made to the residual geological reserves of both Lujing and Huangfengling deposit, and the geological reserves of Yangjiaonao deposit of the depleted mines in Lujing uranium ore-field, central-southern China. The results of static analysis on these reserves show that the residual geological reserves of both Lujing and Huangfengling deposit belong to sub-profitable type, but the ones of Yangjiaonao deposit is profitable with 26.56% tax-before profit. 1 tU profitable type of ore from Yangjiaonao deposit can use 2.40-3.79 tU subprofitable type of ores from Lujing and Huangfengling deposit. In order to solving the problem on scarcity of backup resources of the depleted mines in Lujing uranium ore-field and using the existing sub-profitable type of geological reserves, it is suggested that the high grade of profitable type of deposits should be explored around the exhausting mines so that the production of the mines could be profitable by the pithead heap-leaching mining method with arrangement groups of both sub-profitable and profitable type of ores.

    Full Text Available This article reviews 2 books on FRBR published in the past year. Although both books aim to be introductions to FRBR, their approaches are very different. One is sort of a FRBR study guide with commentary, the other a collection of essays. Robert Maxwell's book, FRBR: A Guide for the Perplexed, takes the study guide approach. Arlene Taylor edited Understanding FRBR: What It Is and How It Will Affect Our Retrieval Tools, a book of essays about FRBR and FRAD, written by cataloging experts, aimed at a broader audience, not just the cataloging specialist. The first seven chapters lay out the basics: introductions to FRBR and FRAD, FRBR research, FRBR and the history of cataloging, FRBR and RDA. These chapters provide an excellent introduction for those new to FRBR. The last seven chapters each look at different types of resources in relation to FRBR.

  16. International symposium on advances in isotope hydrology and its role in sustainable water resources management (IHS-2007). Book of abstracts

    International Nuclear Information System (INIS)

    The quadrennial IAEA isotope hydrology symposia provide an international forum for a comprehensive review of the state of the art and recent advances in this field. The symposia also facilitate the transfer of information, knowledge and interactions between developed and developing countries. Isotopes are increasingly being used to address many of the challenges in sustainable water resources management. The integration of these tools with classical methods and spatial information technologies has been growing rapidly over the past several years. These have provided unsurpassed capabilities to apply nuclear and geochemical techniques in complex hydrological systems. The main objectives of this symposium are to: - Review the state of the art in isotope hydrology; - Outline recent developments in the application of isotope techniques for water resources management; - Identify future trends and developments for research and applications

    While "hydrostatics" has been known since antiquity, the word "hydrodynamics" was only coined by Daniel Bernoulli in 1738. From about that time onward the mechanics of fluids became an important area of physics which attracted the interest of some of the greatest mathematical physicists, including Euler, d'Alembert, Lagrange and Cauchy. Yet, in spite of its undeniable importance in the history of science, hydrodynamics has been largely ignored by modern historians. Fortunately this situation has now changed with the publication of Olivier Darrigol's book, which offers a modern and thorough treatment of the subject from its beginning about 1740 to the 1920s. It is to be hoped that the book will stimulate further interest in the history of hydrodynamics and related areas such as the history of elasticity and aerodynamics, and continuum mechanics in general. Darrigol, who may be best known for his works in the history of quantum and relativity theories, published in 2000 a comprehensive survey of the development of electrodynamics from Ampère to Einstein, a much needed replacement of Edmund Whittaker's classical history of ether and electricity. His present work gives a concise yet wide-ranging synthetic account of the development of hydrodynamics, an area of physics with some historical connections to field electrodynamics.

  20. Uranium extraction technology

    International Nuclear Information System (INIS)

    In 1983 the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA) and the IAEA jointly published a book on Uranium Extraction Technology. A primary objective of this report was to document the significant technological developments that took place during the 1970s. The purpose of this present publication is to update and expand the original book. It includes background information about the principle of the unit operations used in uranium ore processing and summarizes the current state of the art. The publication also seeks to preserve the technology and the operating 'know-how' developed over the past ten years. This publication is one of a series of Technical Reports on uranium ore processing that have been prepared by the Division of Nuclear Fuel Cycle and Waste Management at the IAEA. A complete list of these reports is included as an addendum. Refs, figs and tabs

    Science.gov (United States)

    Roberts, John T.

    Mauro Dorato's new book is subtitled "An Introduction to the History and Philosophy of Laws of Nature". This is a bit misleading: a reader previously unacquainted with any of the literature on the topic of laws of nature and related problems in the philosophy of science will find much of the book prohibitively challenging. But the book does aim for the kind of breadth and generality that one would expect from an introduction to the subject, and it serves well as a compact overview of the issues, views, arguments, and counter-arguments that have shaped the contemporary philosophical debate on laws of nature. Almost no important facet of the debate goes untouched. There are chapters or sections on: recent scholarship on the history of the notion of a law and its role in the study of nature; the characteristics of the things called "laws" in a wide range of sciences; the relations among laws, algorithmic compressibility of information, and the theory of measurement; the puzzling question of why so many laws of nature should be mathematical in form; regularity theories of laws; the universals approach to laws; the necessitarian approach to laws; skeptical eliminativism about laws; non-reductive realism about laws; the question of the supervenience of laws on non-nomic facts; the relations of laws to counterfactuals, causality, dispositions, explanation, chance, symmetry, and necessity; ceteris paribus clauses; the evolutionary contingency thesis and the question of biological laws; Wilhelm Dilthey and the alleged distinction between "nomothetic" sciences and "historical" ones; the question of psychophysical laws and the relation between this question and the problems of mental causation and free will; even the connection between the issue of psychophysical laws and Gibson's ecological theory of perception. This is an impressive range of topics, especially considering that they are all treated in only 174 pages. One result is that not all of them are treated with as

  2. International conference on nuclear knowledge management: Strategies, information management and human resource development. Book of extended synopses

    International Nuclear Information System (INIS)

    In recent years, a number of trends have drawn attention to the need for better management of nuclear knowledge. Depending on region and country, they include an ageing workforce, declining student enrolment figures, the risk of losing nuclear knowledge accumulated in the past, the need for capacity building and transfer of knowledge and recognition of achieving added value through knowledge sharing and networking. The objective of this conference is to reach a clear and common understanding of issues related to nuclear knowledge management for sustaining knowledge and expertise in nuclear science and technology. The conference will provide a forum for professionals and decision makers in the nuclear sector, comprising industry, governments and academia as well as professionals in the knowledge management and information technology sectors; to exchange information and share experience on nuclear knowledge management, comprising strategies, information management and human resource development; to identify lessons learned and to embark on the development of new initiatives and concepts for nuclear knowledge management in IAEA Member States; for the INIS session, to discuss the present status and future developments of INIS. The conference comprised the following topical sessions: Session 1: Nuclear knowledge management - policies and strategies; Managing nuclear information - policies and strategies; Managing nuclear information - case studies; Human resources for the nuclear sector; Networking nuclear education and training. Special sessions were held on: the International Nuclear Information System (INIS); Young Generation in the Nuclear Sector; and 'Innovation and Nuclear Knowledge'

    International Nuclear Information System (INIS)

    The modifications to the Los Alamos Scientific Laboratory (LASL) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program, necessary to incorporate the expansion and revision of the overall HSSR program as required by the Department of Energy, have been completed. To date, approximately 57% of the total area assigned to the LASL in the Rocky Mountain region and Alaska has been sampled and plans are well under way to sample an additional 28% during FY 78. Contracts have been let to complete the sampling of the LASL area in the lower states and bids to sample an additional 33% of Alaska are being evaluated. Twenty reports (2 in press and 18 in preparation) are presently scheduled to be open filed within six months, reporting uranium data only for 18 complete quadrangles and multielement data for 11 complete quadrangles. In addition, data releases are being prepared to open file the uranium data from portions of 13 quadrangles that are now outside the LASL reporting boundary but which had been sampled by the LASL prior to the establishment of the new boundary in October 1977. By the end of the quarter, all multielement analysis systems were operational. Water samples from 7780 locations and sediment samples from 4170 locations were analyzed for uranium. Samples from approximately 6500 locations were analyzed by one or more of the multielement methods

  6. Uranium and environment in Kazakstan

    International Nuclear Information System (INIS)

    Kazakstan's data on uranium as a state report has been included for the first time in the Red Book. Therefore the report contains two large themes presented in Suggested Topics for Papers: Country report, based on the 1995 NEA/IAEA Red Book Questionnaire and environmental impact regulations. Kazakstan is considered as one of the world leaders on uranium supply. In Kazakstan there are many well known types of deposits but the main one is the sandstone-rollfront type. That type is represented by the group of deposits of the Syr-Darya uranium ore province. Deposits of that type include that main part of uranium ore of the Republic of Kazakstan and supply almost all of its uranium mining. At the large three enterprises the uranium is extracted by underground leaching. The mining method of uranium extraction is stopped. Because of the poor development of nuclear energy, Kazakstan's need for uranium is not very high. Presence of a large amount of cheap and technological uranium ores allow the Republic to export uranium. There are plans to increase uranium mining and perhaps to establish new mining facilities including joint-ventures. More than 50 uranium deposits are known in Kazakstan. During prospecting and exploitation of these deposits a large amount of rad wastes in the form of ore dumps and tailings were generated. They have a substantial influence on the environment. Moreover, near the sandstone-rollfront type uranium deposits the large amount of underground water has been contaminated by radionuclides. Special investigation of this phenomenon is necessary. In Kazakstan there are the rad waste disposal conception and contaminated earth recultivation regulations. At present ''The Rad Wastes Management Law'' is submitted for approval. (author). 2 figs

  8. Opening remarks [International symposium on uranium production and raw materials for the nuclear fuel cycle - Supply and demand, economics, the environment and energy security

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency takes a great deal of pride in the role that it played in the early 1990s in bringing together the international uranium community to begin to develop a comprehensive database on uranium supply and to openly exchange ideas on uranium geology, production technology and economics and environmental issues associated with uranium production. One of the most valuable biannual publications jointly issued by OECD/NEA and the IAEA is URANIUM: Resources, Production and demand popularly know as Red Book. The Joint OECD/NEA - IAEA Uranium Group also supports the activities in the front-end of the nuclear fuel cycle. The Agency is committed to serve as a forum for discussion on all aspects of uranium supply and demand and hence this symposium. The ultimate goal of the uranium industry can be stated rather simply - providing an adequate supply of uranium that can be delivered to the market place at competitive prices by environmentally sound production practices. Achieving that goal is, however, anything but simple. The industry faces a number of challenges that can best be met through exchanging ideas at meetings such as this Symposium. New exploration techniques may help to broaden the geographic diversity of the uranium resource base. Diversity of supply in turn can help offset the risk arising out of unforeseen delay in executing uranium mining projects in some areas. Sharing information on new production technology can potentially lead to improved project economics and an increase in the low-cost resource base. Case histories ranging from pre-production licensing to final site rehabilitation are invaluable guides to the time frames and costs associated with environmental planning and compliance. An adequate supply of uranium is essential to the future of nuclear power. This Symposium is intended to bring together the broadly diverse expertise needed to assure that future

    restrict myself to a few remarks. I first admit that I found Spohn's presentation to be tough going. Unlike the pair of delightful books by Cohen-Tannoudji, Dupont-Roc, and Grynberg [6, 7], this is not a gentle introduction to the quantum theory of a charged particle coupled to its own electromagnetic field. Instead, Spohn proceeds rather quickly through the formulation of the theory (defining the Hamiltonian and the Hilbert space) and then presents some applications (for example, he constructs the ground states of the theory, he examines radiation processes, and he explores finite-temperature aspects). There is a lot of material in the eight chapters devoted to the quantum theory, but my insufficient preparation and the advanced nature of Spohn's presentation were significant obstacles; I was not able to draw much appreciation for this material. One of the most useful resources in Spohn's book are the historical notes and literature reviews that are inserted at the end of each chapter. I discovered a wealth of interesting articles by reading these, and I am grateful that the author made the effort to collect this information for the benefit of his readers.

  10. Challenges in the front end of the uranium fuel cycle

    International Nuclear Information System (INIS)

    The long-term fundamentals for nuclear remain strong. Climate change and clean air concerns remain high on the agenda of national energy policies, as both developing and developed economies pursue a strategy of energy diversity and energy security. A global industry of 435 reactors is expected to grow to more than 639 reactors within the next 20 years with the potential for even more rapid expansion. This nuclear generating capacity relies on an international fuel cycle that can ensure stable and secure supply for decades to come. As the first step in the fuel cycle, the uranium industry has received various price signals over the past 5 decades, from the birth of an industry with strong demand and stock pile building and the associated robust pricing and new production stimulation, to an industry in decline and a period marked by liquidation of large inventories, to the recent resurgence of nuclear and the associated uranium price signals. In many ways, understanding the current uranium environment and the outlook for the industry requires some understanding of these phases of nuclear. The global nuclear fleet today needs about 65,000 tonnes of uranium per year to meet reactor feed requirements. Primary production meets about two thirds of this requirement while the remainder is drawn from secondary supply. Secondary supply can essentially be described as stockpiles of previously produced uranium. However, secondary supplies are finite and more primary production will be needed. From a long-term perspective, there is no question that there are sufficient uranium resources to support the nuclear industry for many years to come. The IAEA's 'Red Book' estimates that more than 5 million tonnes of known resources could potentially be developed at today's prices. This is enough to supply the global reactor fleet for almost 80 years at current usage rates. Recently higher uranium prices have resulted in some production increases although the rate of growth has been held

  17. Uranium in alkaline rocks

    Murphy, M.; Wollenberg, H.; Strisower, B.; Bowman, H.; Flexser, S.; Carmichael, I.

    1978-04-01

    Geologic and geochemical criteria were developed for the occurrence of economic uranium deposits in alkaline igneous rocks. A literature search, a limited chemical analytical program, and visits to three prominent alkaline-rock localities (Ilimaussaq, Greenland; Pocos de Caldas, Brazil; and Powderhorn, Colorado) were made to establish criteria to determine if a site had some uranium resource potential. From the literature, four alkaline-intrusive occurrences of differing character were identified as type-localities for uranium mineralization, and the important aspects of these localities were described. These characteristics were used to categorize and evaluate U.S. occurrences. The literature search disclosed 69 U.S. sites, encompassing nepheline syenite, alkaline granite, and carbonatite. It was possible to compare two-thirds of these sites to the type localities. A ranking system identified ten of the sites as most likely to have uranium resource potential.

  19. Addendum to the Book of Abstracts for the international symposium on uranium raw material for the nuclear fuel cycle: Exploration, mining, production, supply and demand, economics and environmental issues (URAM-2009)

    International Nuclear Information System (INIS)

    The International Symposium on Uranium Raw Material for the Nuclear Fuel Cycle: Exploration, Mining, Production, Supply and Demand, Economics and Environmental Issues (URAM-2009) addressed all aspects of the uranium fuel cycle, from the availability of raw materials to the long-term sustainability of nuclear power. The revival of the uranium industry in recent years has caused a dramatic increase in uranium exploration and mining activities in several countries. URAM-2009 was intended to bring together scientists, exploration and mining geologists, engineers, operators, regulators and fuel cycle specialists to exchange information and discuss updated research and current issues in uranium geology and deposits, exploration, mining and processing, production economics, and environmental and legal issues. This addendum contains a key note presentation on nuclear energy and sustainability, and seven poster presentations on uranium exploration, geology and uranium mining and processing. All presentations are indexed individually

  4. Glances on uranium. Tome 2. Exploration, production

    International Nuclear Information System (INIS)

    This book is an homage to all participants of uranium prospecting and mining exploitation who have contributed to satisfy the nuclear energy needs during the last 50 years. The first chapter describes the economical, administrative and environmental constraints of uranium mining projects. The second chapter describes the different steps of the exploration (permits, inventory, mineralisation, quality, resource estimation, quantifying), the direct and indirect exploratory techniques and methods (radiometry, geochemistry, drillings and well logging, mapping, tele-detection, geophysical surveys..) and the exploration costs. The third chapter deals with the legal, administrative, technical, socio-economical and financial aspects which must be taken into account in the risk evaluation of a mining project. Chapter 4 concerns the start up of the project while the development and production methods are detailed in chapter 5 (opencast and underground mining, in-situ lixiviation, ore processing, chemical extraction etc.). The last chapter is devoted to the environmental aspects of uranium mining: legal aspects, nuisances, dusts, contamination, the case of in-situ lixiviation, the rehabilitation of sites. (J.S.)

  5. Uranium conversion

    International Nuclear Information System (INIS)

    FOI, has performed a study on uranium conversion processes that are of importance in the production of different uranium compounds in the nuclear industry. The same conversion processes are of interest both when production of nuclear fuel and production of fissile material for nuclear weapons are considered. Countries that have nuclear weapons ambitions, with the intention to produce highly enriched uranium for weapons purposes, need some degree of uranium conversion capability depending on the uranium feed material available. This report describes the processes that are needed from uranium mining and milling to the different conversion processes for converting uranium ore concentrate to uranium hexafluoride. Uranium hexafluoride is the uranium compound used in most enrichment facilities. The processes needed to produce uranium dioxide for use in nuclear fuel and the processes needed to convert different uranium compounds to uranium metal - the form of uranium that is used in a nuclear weapon - are also presented. The production of uranium ore concentrate from uranium ore is included since uranium ore concentrate is the feed material required for a uranium conversion facility. Both the chemistry and principles or the different uranium conversion processes and the equipment needed in the processes are described. Since most of the equipment that is used in a uranium conversion facility is similar to that used in conventional chemical industry, it is difficult to determine if certain equipment is considered for uranium conversion or not. However, the chemical conversion processes where UF6 and UF4 are present require equipment that is made of corrosion resistant material

    Full Text Available Phillip M. Morse and Herman Feshbach, Professors of Physics at the MIT, published their biblical-sized textbook ‘Methods of Theoretical Physics’ with McGraw-Hill in May 1953. At 1978 pages and published in two books, it is an intimidating twin tome that should still be atop the reading lists or the bookshelves of every mathematical physicist. What material is covered in this book? In the most concise of terms, this book is devoted to the study of differential equations and associated boundary conditions that describe physical fields. The thirteen chapters address what circumstances warrant the use of which differential equations, and most often addresses the question of coordinate system transformations, for example, how do Green's functions for Laplace's Equation transform under different coordinate systems? Under what circumstances the solutions can be expected to be separable? Many examples are covered to illustrate these points. Why is this book relevant to Software Programmers? This book is part of the background that any scientific programmer is likely to need in dealing with physical fields. This book was written before personal computers became ubiquitous, however it is still an outstanding effort to tie the methods of solving differential equations governing fields together in one book. The book never received a second edition, however, it was reprinted to an outstanding standard by Feshbach Publishing since 2004, run by the children of Herman Feshbach. Their website is feshbachpublishing.com. The majority of this review is a mini-commentary of the book showing what is covered in a very terse fashion, which may be useful as a summary even for those who have already read the full text. I then give a brief analysis of the approach to mathematical physics taken by the book. Finally, I will discuss who will benefit from reading this magnificent treatise, nearly 60 years after it was first published.

  7. Remedial action plan and site design for stabilization of the inactive Uranium Mill Tailing site Maybell, Colorado. Attachment 3, ground water hydrology report, Attachment 4, water resources protection strategy. Final report

    International Nuclear Information System (INIS)

    The U.S. Environmental Protection Agency (EPA) has established health and environmental regulations to correct and prevent ground water contamination resulting from former uranium processing activities at inactive uranium processing sites (40 CFR Part 192 (1993)) (52 FR 36000 (1978)). According to the Uranium Mill Tailings Radiation Control Act (UMTRCA) of 1978 (42 USC section 7901 et seq.), the U.S. Department of Energy (DOE) is responsible for assessing the inactive uranium processing sites. The DOE has decided that each assessment will include information on hydrogeologic site characterization. The water resources protection strategy that describes the proposed action compliance with the EPA ground water protection standards is presented in Attachment 4, Water Resources Protection Strategy. Site characterization activities discussed in this section include the following: (1) Definition of the hydrogeologic characteristics of the environment, including hydrostratigraphy, aquifer parameters, areas of aquifer recharge and discharge, potentiometric surfaces, and ground water velocities. (2) Definition of background ground water quality and comparison with proposed EPA ground water protection standards. (3) Evaluation of the physical and chemical characteristics of the contaminant source and/or residual radioactive materials. (4) Definition of existing ground water contamination by comparison with the EPA ground water protection standards. (5) Description of the geochemical processes that affect the migration of the source contaminants at the processing site. (6) Description of water resource use, including availability, current and future use and value, and alternate water supplies

    2007-06-01

    The study of braneworlds has been an area of intense activity over the past decade, with thousands of papers being written, and many important technical advances being made. This book focuses on a particular aspect of braneworlds, namely perturbative gravity in one specific model: the Randall-Sundrum model. The book starts with an overview of the Randall-Sundrum model, discussing anti-de Sitter (AdS) space and the Israel equations in some detail. It then moves on to discuss cosmological branes, focusing on branes with constant curvature. The book then turns to brane gravity, i.e. what do we, as brane observers, perceive the gravitational interaction to be on the brane as derived from the actual five-dimensional gravitational physics? After a derivation of the general brane equations from the Israel equations, the remainder of the book deals with perturbative gravity. This part of the book is extremely detailed, with calculations given explicitly. Overall, the book is quite pedagogical in style, with the aim being to explain in detail the topics it chooses to cover. While it is not unusual to have books written on current and extremely popular research areas, it is unusual to have calculations written so explicitly. This is both a strength and a weakness of this book. It is a strength because the calculations are presented in a detail that students learning the topic will definitely appreciate; however, the narrow focus of the book also means that it lacks perspective and fails to present the broader context. In choosing to focus on one particular aspect of Randall-Sundrum branes, the book has not managed to communicate why a large number of theorists have worked so intensively on this model. In its early stages, the explicit detail of the Randall-Sundrum model would be extremely useful for a student starting out in this research area. In addition, the calculational detail later in the computation of the graviton propagator on the brane would also be welcome not
