  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

    Energy Technology Data Exchange (ETDEWEB)

    Vance, Robert [OECD Nuclear Energy Agency, Issy-les-Moulineaux (France)

    2009-05-15

    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 1{sup st} 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.)

  3. Uranium resources, production and demand 1993

    International Nuclear Information System (INIS)

    This book is the Japanese edition of 'Uranium Resources, Production and Demand, 1993' published by OECD/NEA-IAEA in 1994. It contains data on uranium exploration activities, resources and production for about 50 countries. (K.I.)

  4. 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.)

  5. 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

    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. This 23rd edition provides a comprehensive review of world uranium supply and demand as of 1 January 2009, as well as data on global ur...

  11. 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.)

  12. Present status of uranium resource development in foreign countries, 1984

    International Nuclear Information System (INIS)

    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.)

  15. 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

  16. Uranium Resources and Supply - Demand to 2030

    Energy Technology Data Exchange (ETDEWEB)

    Vance, Robert [Le Seine St. Germain, 12, boulevard des Iles, Issy-les-Moulineaux, 92130 (France)

    2009-06-15

    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 U{sub 3}O{sub 8}) 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

  17. 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

  18. 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.

  19. 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

  20. Book review: Mineral resource estimation

    Mihalasky, Mark J.

    2016-01-01

    Mineral Resource Estimation is about estimating mineral resources at the scale of an ore deposit and is not to be mistaken with mineral resource assessment, which is undertaken at a significantly broader scale, even if similar data and geospatial/geostatistical methods are used. The book describes geological, statistical, and geostatistical tools and methodologies used in resource estimation and modeling, and presents case studies for illustration. The target audience is the expert, which includes professional mining geologists and engineers, as well as graduate-level and advanced undergraduate students.

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

  3. 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

  5. URANIUM 1991 resources, production and demand

    International Nuclear Information System (INIS)

    The uranium supply aspects of the nuclear fuel cycle have undergone considerable change during the last few years. Nuclear power generating capacity can continue to expand only if there is confidence in the final supply of uranium. This report presents governmental compilations of uranium resource and production data, as established in 1991. It also presents short-term projections of the nuclear industry future natural uranium requirements and reviews the status of uranium exploration, resources and production throughout the world. 10 refs., 14 figs., 15 tabs., 6 appendices

  6. 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

    2008-01-01

    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.

  9. 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

  10. 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)

  11. 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

  12. 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).

  13. 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

  14. Uranium resources, production and demand in South Africa

    International Nuclear Information System (INIS)

    This paper provides a review of the historical development of the South African uranium market and the current status of uranium exploration, resources and production. A prognosticated view of possible future demand for uranium in South Africa is attempted, taking cognisance of the finite nature of the country's coal resources and estimated world uranium demand. Although well endowed with uranium resources, South Africa could face a shortage of this commodity in the next century, should the predicted electricity growth materials. (author)

  15. 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.

  16. 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

    The U.S. Department of Energy, Energy Information Administration (EIA) joined with the U.S. Department of the Interior, U.S. Geological Survey (USGS) to analyze the world uranium supply and demand balance. To evaluate short-term primary supply (0–15 years), the analysis focused on Reasonably Assured Resources (RAR), which are resources projected with a high degree of geologic assurance and considered to be economically feasible to mine. Such resources include uranium resources from mines currently in production as well as resources that are in the stages of feasibility or of being permitted. Sources of secondary supply for uranium, such as stockpiles and reprocessed fuel, were also examined. To evaluate long-term primary supply, estimates of uranium from unconventional and from undiscovered resources were analyzed. At 2010 rates of consumption, uranium resources identified in operating or developing mines would fuel the world nuclear fleet for about 30 years. However, projections currently predict an increase in uranium requirements tied to expansion of nuclear energy worldwide. Under a low-demand scenario, requirements through the period ending in 2035 are about 2.1 million tU. In the low demand case, uranium identified in existing and developing mines is adequate to supply requirements. However, whether or not these identified resources will be developed rapidly enough to provide an uninterrupted fuel supply to expanded nuclear facilities could not be determined. On the basis of a scenario of high demand through 2035, 2.6 million tU is required and identified resources in operating or developing mines is inadequate. Beyond 2035, when requirements could exceed resources in these developing properties, other sources will need to be developed from less well-assured resources, deposits not yet at the prefeasibility stage, resources that are currently subeconomic, secondary sources, undiscovered conventional resources, and unconventional uranium supplies.

  20. 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

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

    Energy Technology Data Exchange (ETDEWEB)

    Goodknight, C.S.; Burger, J.A. (comps.)

    1982-10-01

    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 1/sup 0/ x 2/sup 0/ 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.

  2. 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

  4. 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

  5. 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.

  7. 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

Appendices on pricing of uranium and incentives for production since World War II are also presented

  9. 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

  10. 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. 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.

  12. 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)

  13. 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

  14. 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)

  15. 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.

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

  18. 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)

  19. 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

  2. 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

The 2013 White Book is a snapshot of conditions as of October 1, 2013, documenting the loads and resources for the Federal system and region for the 10-year study period OY 2014 through 2023. The White Book contains projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. The White Book also contains information obtained from formalized resource planning reports and data submittals including those from individual utilities, the Northwest Power and Conservation Council (Council), and the Pacific Northwest Utilities Conference Committee (PNUCC). Starting with the 2012 White Book, BPA changed the annual production schedule for future White Books. BPA is scheduled to publish a complete White Book, which includes a Federal System Needs Assessment analysis, every other year (even years). In the odd-numbered years, BPA will publish a biennial summary update (Supplement) that only contains major changes to the Federal System and Regional System analyses that have occurred since the last White Book. http://www.bpa.gov/power/pgp/whitebook/2013/index.shtml.

  5. 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

  6. 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

    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

  10. 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)

  11. 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

    Australia has the largest uranium resources in the world with over 1.5 M tonnes U (1.8 M tonnes U{sub 3}O{sub 8}) in the lowest cost categories (reasonably assured and inferred resources less than US $130/kg U). This represents about 40% of the world's low-cost resources of uranium. Resources in the next five major uranium resource countries are: 817,000 te U in Kazakhstan, 546,000 te U in Russia, 435,000 te U in South Africa and 423,000 te U in Canada (based on Nea/IAEA data in 2007; new data expected to be published in 2010). Uranium production in Australia in calendar year 2009 was 7,982 te U which represented 20% of production from the world's uranium mines. This production came from three uranium mines at Ranger, Northern Territory, and Olympic Dam and Beverley in South Australia. Customers were utilities in the USA, Japan, Korea, Taiwan and seven countries in the European Union. In comparison with other major producing countries, Kazakhstan had the largest production in 2009 with 14,020 te U, followed by Canada with 10,173 te U. The prospects are very good for increasing Australia's uranium resources by additional exploration and increasing production by opening new mines and by expanding production at existing mines, particularly at Olympic Dam. Australia does not have a nuclear power plant and relies very heavily on coal-based electricity. The introduction of carbon constraints on future electricity production will make nuclear power an increasingly competitive source of base-load electricity in Australia. (Author)

  13. 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

  14. 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 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.

    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.

    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.

    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.

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...

  4. 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)

    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

    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

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)

  14. 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

    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. 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. 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

  16. 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

  17. 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

  18. 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.

  20. 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.

    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

  3. 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

  4. 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.

  6. 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

  7. 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.

  8. 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

    Full Text Available 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 uranium resources to try to define the possible extent and location of undiscovered uranium resources. This paper is an account of this project. Depuis le mois d'août 1965, l'Agence pour l'Énergie Nucléaire (AEN de l'OCDE - et, à partir de 1967, de concert avec l'Agence Internationale de l'Énergie Atomique (AIEA - a publié périodiquement des rapports sur les ressources et la demande en uranium. Les estimations des ressources en uranium fournies dans ces rapports, comme on l'a reconnu depuis, n'ont pas correspondu à une estimation complète des ressources mondiales en uranium et, par conséquent, une étude plus importante - peut-être la première de son espèce - a été entreprise par un groupe international d'experts pour essayer de définir l'importance et la localisation éventuelles de ces ressources en uranium qui n'étaient pas encore trouvées. Le contenu de cette communication est un historique de ce projet.

    Finch, Warren Irvin; McCammon, Richard B.

    1987-01-01

    Based on the Memorandum of Understanding {MOU) of September 20, 1984, between the U.S. Geological Survey of the U.S. Department of Interior and the Energy Information Administration {EIA) of the U.S. Department of Energy {DOE), the U.S. Geological Survey began to make estimates of the undiscovered uranium endowment of selected areas of the United States in 1985. A modified NURE {National Uranium Resource Evaluation) method will be used in place of the standard NURE method of the DOE that was used for the national assessment reported in October 1980. The modified method, here named the 'deposit-size-frequency' {DSF) method, is presented for the first time, and calculations by the two methods are compared using an illustrative example based on preliminary estimates for the first area to be evaluated under the MOU. The results demonstrate that the estimate of the endowment using the DSF method is significantly larger and more uncertain than the estimate obtained by the NURE method. We believe that the DSF method produces a more realistic estimate because the principal factor estimated in the endowment equation is disaggregated into more parts and is more closely tied to specific geologic knowledge than by the NURE method. The DSF method consists of modifying the standard NURE estimation equation, U=AxFxTxG, by replacing the factors FxT by a single factor that represents the tonnage for the total number of deposits in all size classes. Use of the DSF method requires that the size frequency of deposits in a known or control area has been established and that the relation of the size-frequency distribution of deposits to probable controlling geologic factors has been determined. Using these relations, the principal scientist {PS) first estimates the number and range of size classes and then, for each size class, estimates the lower limit, most likely value, and upper limit of the numbers of deposits in the favorable area. Once these probable estimates have been refined

    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.

  13. 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

  15. 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

  16. 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

    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.

  20. Investigation of Jordanian uranium resources in carbonate rocks

    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.

  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. 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

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

    Science.gov (United States)

    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

  5. 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)

    Directory of Open Access Journals (Sweden)

    Valerij DERMOL

    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.

    The Albany 10 x 20 Quadrangle, Massachusetts, New York, Connecticut, Vermont, and New Hampshire, was evaluated to a depth of 1500 m for uranium favorability using National Uranium Resource Evaluation criteria. Areas of favorable geology and aeroradioactivity anomalies were examined and sampled. Most Triassic and Jurassic sediments in the Connecticut Basin, in the central part of the quadrangle, were found to be favorable for sandstone uranium deposits. Some Precambrian units in the southern Green Mountains of Vermont were found favorable for uranium deposits in veins in metamorphic rocks

  9. 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

  11. 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

  13. 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.

    Energy Technology Data Exchange (ETDEWEB)

    O' Neill, A J; Thiede, D S

    1982-05-01

    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.

    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

    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.

  5. 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)

    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.

    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.

  11. 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.

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

    International Nuclear Information System (INIS)

    Niue is described as a coral island containing 259 square kilometers, located between Tonga and the Southern Cook Islands in the Central Pacific. Geologically, little is known, or can be deduced from available information, therefore reported occurrences of uranium are the basis for a potential in category 1 (less than 1,000 tonnes U) .

  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. National Uranium Resource Evaluation: Torrington Quadrangle, Wyoming and Nebraska

    Energy Technology Data Exchange (ETDEWEB)

    Seeland, D

    1982-09-01

    The Torrington 1/sup 0/ x 2/sup 0/ Quadrangle in southeastern Wyoming and western Nebraska was evaluated to identify areas favorable for the occurrence of uranium deposits likely to contain 100 tons of uranium with an average grade of not less than 100 ppM (0.01 percent) U/sub 3/O/sub 8/. Almost all uranium occurrences reported in the literature were visited and sampled. Geochemical analyses of rock samples collected during the study were used in the evaluation. Hydrogeochemical and stream-sediment analyses were not available. Aerial-radiometric, and helium soil-gas surveys were analyzed. Much of the quadrangle is covered by Tertiary rocks. To assess the uranium potential of the Tertiary and pre-Tertiary rocks 270 well logs were studied and both contour and geologic maps made of the pre-Oligocene surface east and north of the Laramie Mountains. Five environments favorable for uranium deposits were outlined. The first is in the coarse-grained arkosic sandstone facies of the Wasatch Formation and the Lebo Member of the Fort Union Formation in the southern Powder River Basin. The second is in the Wind River Formation in the Shirley Basin, a stratigraphic and lithologic equivalent of the Wasatch. The third is the Lower Cretaceous Cloverly Formation in the northeastern part of the quadrangle. The fourth is in the Upper Cretaceous Lance (Laramie) Formation and the Fox Hills Sandstone in the southeastern corner of the quadrangle. The fifth favorable environment is in Precambrian rocks in the Laramie Mountains and Hartville uplift.

  16. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Colombia. February - March 1980

    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). There are, at

  17. Quantitative Assay and Evaluation of Uranium Levels in Water Resources of Egypt

    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

  18. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Chile

    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

  19. 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

    Zhang, Jie-lin

    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.

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

    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.

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

    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

  3. 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)

  4. 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

  6. 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)

  7. 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.

    Maldives, an archipelago consisting of between 1,000 and 2,000 islands and atolls in the Indian Ocean contain only 300 square kilometers and is populated by around 130,000 people who are engaged in raising of copra, fruits, taro, and other agricultural products, and in fishing. 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)

  11. 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

  12. 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)

  13. 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)

    1982-09-01

    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 1/sup 0/ x 2/sup 0/ 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.

  20. 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

  1. 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

  2. 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

  5. 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)

  6. 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

    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.

  9. 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

  11. 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

    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)

  13. 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)

  14. 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

    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.

  16. 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

    Unconventional uranium resources in China mainly include black-rock series, peat, salt lake and evaporitic rocks. Among them, uraniferous black-rock series, uraniferous phosphorite and uranium-polymetallic phosphorite connected with black-rock series are important types for the sustainable support of uranium resources in China. Down-faulting and epocontinental rift in continental margin are the most important and beneficial ore-forming environment for unconventional uranium resources of black-rock series in China and produced a series of geochemistry combinations, such as, U-Cd, U-V-Mo, U-V-Re、U-V-Ni-Mo and U-V-Ni-Mo-Re-Tl. Unconventional uranium resources of black-rock series in China is related to uranium-rich marine black-rock series which are made up of hydrothermal sedimentary siliceous rocks, siliceous phospheorite and carbonaceous-siliceous-pelitic rock and settled in the continental margin down-faulting and epicontinental rift accompanied by submarine backwash and marine volcano eruption. Hydrothermal sedimentation or exhalation sedimentary is the mechanism to form unconventional uranium resources in black-rock series or large scale uranium-polymetallic mineralization in China.%中国非常规铀资源主要包含黑色岩系型和盐湖型。其中与黑色岩系有关的含铀黑色岩系型、含铀磷块岩型、铀多金属磷块岩型是对中远期保障我国铀资源可持续供给有重要意义的类型。陆缘裂谷、陆缘裂陷环境是中国黑色岩系非常规铀资源最重要、最有利的成矿环境,形成U-Cd型、U-V-Mo型、U-V-Re型、U-V-Ni-Mo型和U-V-Ni-Mo-Re-T1型等地球化学组合。中国黑色岩系非常规铀资源铀成矿作用受控于陆缘裂谷、陆缘裂陷环境下伴随海底喷流作用和海底火山喷发而沉积的由热水沉积硅质岩、硅质磷块岩和碳硅泥岩组成的富铀海相黑色岩系,热水沉积作用或喷气-沉积是形成中国黑色岩系非常规铀资源或发生大规

  19. 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

  20. 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

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

    International Nuclear Information System (INIS)

    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.

    CALFLT is a FORTRAN program developed to plot aerial data for the Aerial Radiometric and Magnetic Survey (ARMS) portion of the National Uranium Resource Evaluation (NURE) program. It is an inexpensive way of displaying any aerial data for mineral exploration. A magnitude profile plot of the data points along a flightline is overlayed with one of five map projections at virtually any scale. The projections convert latitude/longitude into easting/northing coordinates which are then converted into (X,Y) locations, in plotter units, for plotting.

  9. 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

    Energy Technology Data Exchange (ETDEWEB)

    Mudd, Gavin M., E-mail: Gavin.Mudd@monash.edu

    2014-02-01

    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.

  11. 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

  13. 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

    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

  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

  18. 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

    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.

    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

    1982-06-01

    The purpose of this program has been to evaluate the recently developed solid state photomultiplier tube (SSPMT) technology as a potential improvment to future uranium exploration instrumentation. To this end, six SSPMTs have been constructed and evaluated in a manner similar to that of conventional phototubes. Special regard has been placed on the measurement of pulse height resolution and the factors that affect it in tube design and manufacture. The tubes were subjected to a number of tests similar to those performed on conventional photomultiplier tubes. The results indicate that good, high-resolution spectra can be obtained from the tubes and that they behave generally in a predictable manner. They exhibited a linear gain increase with applied potential. They show only slight dependence of performance with applied potential. Their sensitivity is, for the most part, uniform and predictable. However, several characteristics were found that were not predictable. These include a general drop in measured quantum efficiency, a worsening resolution with operation, and a bump in the sensitivity curve corresponding to the shape of the projected dimension of the anode. The SSPMT remains an attractive new technology in gamma-ray spectroscopy, and promises to make significant improvements in the area of uranium exploration instrumentation. 16 figures, 5 tables.

  7. 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

    Adamson, Matthew

    2016-03-01

    This study explores the origins and consequences of a unique, secret, French-American collaboration to prospect for uranium in 1950s Morocco. This collaboration permitted mediation between the United States and France. The appearance of France in an American-supported project for raw nuclear materials signalled American willingness to accept a new nuclear global order in which the French assumed a new, higher position as regional nuclear ally as opposed to suspicious rival. This collaboration also permitted France and the United States to agree tacitly to the same geopolitical status for the French Moroccan Protectorate, a status under dispute both in Morocco and outside it. The secret scientific effort reassured the French that, whatever the Americans might say publicly, they stood behind the maintenance of French hegemony in the centuries-old kingdom. But Moroccan independence proved impossible to deny. With its foreseeable arrival, the collaboration went from seductive to dangerous, and the priority of American and French geologists shifted from finding a major uranium lode to making sure that nothing was readily available to whatever post-independence interests might prove most powerful. Ultimately, the Kingdom of Morocco took a page out of the French book, using uranium exploration to assert sovereignty over a different disputed territory, its de facto colony of the Western Sahara.

This collaboration also permitted France and the United States to agree tacitly to the same geopolitical status for the French Moroccan Protectorate, a status under dispute both in Morocco and outside it. The secret scientific effort reassured the French that, whatever the Americans might say publicly, they stood behind the maintenance of French hegemony in the centuries-old kingdom. But Moroccan independence proved impossible to deny. With its foreseeable arrival, the collaboration went from seductive to dangerous, and the priority of American and French geologists shifted from finding a major uranium lode to making sure that nothing was readily available to whatever post-independence interests might prove most powerful. Ultimately, the Kingdom of Morocco took a page out of the French book, using uranium exploration to assert sovereignty over a different disputed territory, its de facto colony of the Western Sahara.

    International Nuclear Information System (INIS)

    The potential for uranium deposits appears to be poor in Cambodia. It is largely alluvium. Uranium may occur in discordant deposits in metamorphics and intrusives in the Cardamon and Elephant Hills in the south, and in placers of U/TH minerals in the delta or banks of the Mekong River. The potential is in category 1 (less than 1000 tonnes U ). (author)

  13. 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

  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

  15. 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

  16. Hydrogeochemical and stream-sediment reconnaissance, orientation study, Ouachita Mountain area, Arkansas. National Uranium Resource Evaluation Program

    International Nuclear Information System (INIS)

    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, NO3, NH3, SO4, and PO4. 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

  17. 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

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

    International Nuclear Information System (INIS)

    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

    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.

    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)

  7. 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)

  8. 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

  9. Environmental control technology for mining and milling low-grade uranium resources

    International Nuclear Information System (INIS)

    This study examined the type and level of wastes that would be generated in the mining and milling of U3O8 from four potential domestic sources of uranium. The estimated costs of the technology to control these wastes to different degrees of stringency are presented

    The Fiji Islands, comprising over 300 islands, with a total area of 18,700 square kilometers are basically either volcanic or coral. A small mining industry exists, however, and on the basis of that fact, and without geologic support of any kind a Category 1 (0 to 1,000 tonnes U) uranium potential has been assigned. (author)

  11. 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

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

  13. Geochemical orientation survey of stream sediment, stream water, and ground water near uranium prospects, Monticello area, New York. National Uranium Resource Evaluation Program

    Energy Technology Data Exchange (ETDEWEB)

    Rose, A. W.; Smith, A. T.; Wesolowski, D.

    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.

  14. 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

  19. 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)

    The purpose of this study was to investigate radiologist and trainee-preferred sources for solving imaging questions. The institutional review board determined this study to be exempt from informed consent requirements. Web-based surveys were distributed to radiology staff and trainees at 16 academic institutions. Surveys queried ownership and use of tablet computers and habits of utilization of various electronic and hardcopy resources for general reference. For investigating specific cases, respondents identified a single primary resource. Comparisons were performed using Fisher's exact test. For staff, use of Google and online journals was nearly universal for general imaging questions (93 [103/111] and 94 % [104/111], respectively). For trainees, Google and resident-generated study materials were commonly utilized for such questions (82 [111/135] and 74 % [100/135], respectively). For specific imaging questions, online journals and PubMed were rarely chosen as a primary resource; the most common primary resources were STATdx for trainees and Google for staff (44 [55/126] and 52 % [51/99], respectively). Use of hard copy journals was nearly absent among trainees. Sixty percent of trainees (78/130) own a tablet computer versus 41 % of staff (46/111; p = 0.005), and 71 % (55/78) of those trainees reported at least weekly use of radiology-specific tablet applications, compared to 48 % (22/46) of staff (p Google for both general and specific imaging queries, while residents utilize customized, radiology-focused products and apps. Interestingly, residents note continued use of hard copy books but have replaced hard copy journals with online resources.

  1. National uranium resource evaluation. Geology and recognition criteria for sandstone uranium deposits of the salt wash type, Colorado Plateau Province. Final report

    International Nuclear Information System (INIS)

    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

    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.

  3. Uranium Provinces in China

    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.

  7. 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

  11. 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

    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.

    This is the Web version of a CD-ROM publication. This report consists of summary major compilations and syntheses accomplished in the six-year project through April 2003 for the study on the Mineral Resources, Metallogenesis, and Tectonics of Northeast Asia (Eastern and Southern Siberia, Mongolia, Northeastern China, South Korea, and Japan). The major scientific goals and benefits of the project are to: (1) provide a comprehensive international data base on the mineral resources of the region that is the first, extensive knowledge available in English; (2) provide major new interpretations of the origin and crustal evolution of mineralizing systems and their host rocks, thereby enabling enhanced, broad-scale tectonic reconstructions and interpretations; and (3) promote trade and scientific and technical exchanges between the North America and Northeast Asia. Data from the project are providing sound scientific data and interpretations for commercial firms, governmental agencies, universities, and individuals that are developing new ventures and studies in the project area, and for land-use planning studies that deal with both mineral potential issues. Northeast Asia has vast potential for known and undiscovered mineral deposits; however, little information existed in English in the West until publication of products from this project. Consequently, data and interpretations from the project are providing basic knowledge for major scientific, commercial, national, and international endeavors by other interested individuals and groups.

    豆乍山花岗岩是桂东北重要的产铀花岗岩之一,通过精细矿物学研究,豆乍山花岗岩中绿泥石主要为铁绿泥石和辉绿泥石,而含铀副矿物的蚀变和形成温度相对较高的铁绿泥石密切相关.花岗岩中主要富铀副矿物为晶质铀矿、锆石、独居石、磷钇矿和铀钍石,其中晶质铀矿是公认铀源矿物,而其他副矿物的赋存状态及蚀变特征决定了其是否为铀源矿物.锆石多未发生蚀变,U仍保持其结构中,因此不是铀源矿物;而铁绿泥石附近的独居石和磷钇矿均发生不同程度的蚀变,蚀变作用不仅使独居石和磷钇矿结构中的U 得以释放进入热液,而且原磷钇矿包裹的铀钍石变为赋存于次生磷灰石中,其所含铀容易活化而成为铀源矿物.总之,在豆乍山产铀花岗岩含铀副矿物中,晶质铀矿、蚀变的独居石和磷钇矿、次生磷灰石中铀钍石是铀源矿物.%Douzhashan granite is an important uranium-bearing granite in Miaoershan uranium ore field, northeastern Guangxi. Based on mineralogical study, chlorites can be classified as two types; ripidolite and diabantite, and the alteration of U-riched accessory minerals is closely correlated to the ripidolite which formed in higher temperature. The major hosted minerals for uranium are uraninite, zircon, monazite, xenotime and thorite-coffinite. Among these U-riched minerals, uraninite is generally acknowledged as uranium resource mineral, but if the other U-riched minerals are uranium resource minerals depend on their occurrence and alteration. Most zircons are unaltered and still preserved U in internal structure, so zircon is not a uranium resource mineral. In near ripidolite, monazite and xenotime often have various degrees of alteration. The hydrothermal alteration not only made the uranium liberated from the altered accessory minerals into fluid, but also changed the occurrence of thorite-coffinite from included in xenotime to secondary

  18. 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

  20. 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

  1. 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)

  3. 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

    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.

    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.

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.

    South Korea attaches great importance to the collation,cataloging and digitization of ancient books.With the development of literature digitalization,classical collection institutions in South Korea have begun to digitize ancient books,exploited and built a large number of ancient book digital resources.The construction of ancient book digital resources in China has characteristics such as rich resource types,multiple building units,diverse data format,so it is difficult to integrate and share these resources.We should learn from experience of the construction of ancient book digital resources in South Korea,set up collaborative institution,use normal and compatible data format,and build the open resource acquisition platform,in order to improve the construction of ancient book digital resources and provide users more complete services.%韩国十分重视古籍的整理、编目和数字化工作。随着文献数字化工作的开展,韩国各典藏机构开始将历代古籍进行数字化处理,开发并建设了大量古籍数字资源。由于我国的古籍数字资源建设存在资源类型丰富、开发建置单位多元、格式多样等特点,古籍数字化资源难以整合与共享。我国古籍数字资源建设应借鉴韩国的经验,设置由政府组织的统一协作机构,使用标准、可兼容的数据格式,建设开放的资源获取平台,以完善古籍数字资源建设,为用户提供更好的服务。

  10. 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)

  11. 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

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

    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

  15. 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

  17. National Geochemical Database reformatted data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program

    Science.gov (United States)

    Smith, Steven M.

    1997-01-01

    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

  18. 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

    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

  3. 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.

    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(-), SO4(2-)). 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 (234)U/(238)U 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.

  7. 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

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.

    Research on uranium deposits in Canada, conducted as a prerequisite for assessment of the Estimated Additional Resources of uranium, revealed that (a) the uranium-gold association in rudites of the Huronian Supergroup preferably occurs in the carbon layers; (b) chloritized ore at the Panel mine, Elliot Lake, Ontario, occurs locally in tectonically disturbed areas in the vicinity of diabase dykes; (c) mineralization in the Black Sturgeon Lake area, Ontario, formed from solutions in structural and lithological traps; (d) the Cigar Lake deposit, Saskatchewan, has two phases of mineralization: monomineralic and polymetallic; (e) mineralization of the JEB (Canoxy Ltd.) deposit is similar to that at McClean Lake; (f) the uranium-carbon assemblage was identified in the Claude deposit, Carswell Structure; and (g) the Otish Mountains area, Quebec, should be considered as a significant uranium-polymetallic metallogenic province

  11. 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

    A brief summary of the history of discovery and exploration of uranium deposits in Koepruebasi area with sampling activities would be made. A short description of the laboratory, bench scale and pilot plant tests performed at MTA (Directorate of Mineral Research and Exploration of Turkey) laboratories and at site in Koepruebasi pilot plant facilities will be given together with a assessment of the results obtained. A critical evaluation of the availability of mine able reserves, assessment of the reserve calculations, economical cut-off-grade concept used will be presented. The results of the preliminary and detailed feasibility analysis prepared by experts working together with teams from MTA, Etibank (now Eti Holding A.S.), UNDP and IAEA at different stages of progress in the development of the deposits. The conclusions are re-evaluated taking into account the current uranium market with criteria used for investment decision at the time

  18. Uranium in alkaline rocks

    International Nuclear Information System (INIS)

    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

  20. Hydrogeochemical and stream sediment reconnaissance of the National Uranium Resource Evaluation Program. Progress report, January--March 1978

    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

    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.

  4. BOOK REVIEW: Two Books about FRBR, Compared

    2008-09-01

    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.

    Total intensity magnetic anomaly data acquired as a supplement to radiometric data in the DOE National Uranium Resource Evaluation (NURE) Program are useful in preparing regional profile and contour maps. Survey-contractor-supplied magnetic anomaly data are subjected to a multiprocess, computer-based procedure which prepares these data for presentation. This procedure is used to produce the following machine plotted maps of National Topographic Map Series quadrangle units at a 1:250,000 scale: (1) profile map of contractor-supplied magnetic anomaly data, (2) profile map of high-cut filtered data with contour levels of each profile marked and annotated on the associated flight track, (3) profile map of critical-point data with contour levels indicated, and (4) contour map of filtered and selected data. These quadrangle maps are supplemented with a range of statistical measures of the data which are useful in quality evaluation.

    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.

  14. Uranium in Canada

    International Nuclear Information System (INIS)

    In 1988 Canada's five uranium producers reported output of concentrate containing a record 12,470 metric tons of uranium (tU), or about one third of total Western world production. Shipments exceeded 13,200 tU, valued at $Cdn 1.1 billion. Most of Canada's uranium output is available for export for peaceful purposes, as domestic requirements represent about 15 percent of production. The six uranium marketers signed new sales contracts for over 11,000 tU, mostly destined for the United States. Annual exports peaked in 1987 at 12,790 tU, falling back to 10,430 tU in 1988. Forward domestic and export contract commitments were more than 70,000 tU and 60,000 tU, respectively, as of early 1989. The uranium industry in Canada was restructured and consolidated by merger and acquisition, including the formation of Cameco. Three uranium projects were also advanced. The Athabasca Basin is the primary target for the discovery of high-grade low-cost uranium deposits. Discovery of new reserves in 1987 and 1988 did not fully replace the record output over the two-year period. The estimate of overall resources as of January 1989 was down by 4 percent from January 1987 to a total (measured, indicated and inferred) of 544,000 tU. Exploration expenditures reached $Cdn 37 million in 1987 and $59 million in 1988, due largely to the test mining programs at the Cigar Lake and Midwest projects in Saskatchewan. Spot market prices fell to all-time lows from 1987 to mid-1989, and there is little sign of relief. Canadian uranium production capability could fall below 12,000 tU before the late 1990s; however, should market conditions warrant output could be increased beyond 15,000 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are now or are expected to be in service by the late 1990s. There is significant potential for discovering additional uranium resources. Canada's uranium production is equivalent, in

    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

    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.

  4. Kvanefjeld uranium project

    International Nuclear Information System (INIS)

    The purpose of the Kvanefjeld uranium project is to evaluate the possibility of a uranium production from the deposit at Narssaq, South Greenland. The project comprises investigations in the fields of geology, mining, process chemistry and technology, economy and environment protection. The predominant uraniferous rock is a nepheline syenite called lujavrite in which the main uranium mineral is steenstrupine. The deposit can be mined in an open pit. Calculations have shown a resource of 56 million tonnes of ore with an average grade of 365 ppm corresponding to 20,400 tonnes of uranium. The uranium is extracted by a sodium carbonate solution at 260degC in an autoclave. A pilot plant has been established including ball mill, continuous pipe autoclave and a belt filter for separation of leach liquor and residue. The uranium is finally precipitated as UO2 by reduction in an autoclave at 260degC. With the existing ore sample, recoveries of more than 80% have been obtained. The carbonate leaching causes a low solubility of most contaminants in the tailings. A draft project has been prepared for an industrial plant in Greenland. The total investments have been calculated at 3 x 109 Dkr. Electrical energy is assumed to be supplied by a hydropower plant at Johan Dahl Land. The mine and mill are expected to employ 500-600 persons. (author)

  6. Exploitation Contradictions Concerning Multi-Energy Resources among Coal, Gas, Oil, and Uranium: A Case Study in the Ordos Basin (Western North China Craton and Southern Side of Yinshan Mountains

    Full Text Available The particular “rich coal, meager oil, and deficient gas” energy structure of China determines its high degree of dependence on coal resources. After over 100 years of high-intensity mining activities in Northeast China, East Region, and the Southern Region, coal mining in these areas is facing a series of serious problems, which force China’s energy exploitation map to be rewritten. New energy bases will move to the western and northern regions in the next few years. However, overlapping phenomena of multiple resources are frequently encountered. Previous exploitation mainly focused on coal mining, which destroys many mutualistic and accompanying resources, such as uranium, gas, and oil. Aiming at solving this unscientific development mode, this research presents a case study in the Ordos Basin, where uranium, coal, and gas/oil show a three-dimensional overlapping phenomenon along the vertical downward direction. The upper uranium and lower coal situation in this basin is remarkable; specifically, coal mining disturbs the overlaying aquifer, thus requiring the uranium to be leached first. The technical approach must be sufficiently reliable to avoid the leakage of radioactive elements in subsequent coal mining procedures. Hence, the unbalanced injection and extraction of uranium mining is used to completely eradicate the discharged emissions to the environment. The gas and oil are typically not extracted because of their deep occurrence strata and their overlapping phenomenon with coal seams. Use of the integrated coal and gas production method is recommended, and relevant fracturing methods to increase the gas migrating degree in the strata are also introduced. The results and recommendations in this study are applicable in some other areas with similarities.

  7. National Uranium Resource Evaluation Program. Regional hydrogeochemical and stream sediment survey of the Llano NTMS Quadrangle, Texas

    International Nuclear Information System (INIS)

    Groundwater data (161 samples) show that an area encompassing groundwater samples with >= 6.45 ppB U is present in the central portion of the study area. These samples are produced primarily from the Valley Springs Gneiss, Town Mountain Granite, and younger granites. High specific conductance values do not correlate strongly with high U values, indicating that U in groundwater is not a function of dissolved solids. Li, Si, K, Na, Cl, and SO4 correlate positively with U, while total alkalinity, pH, and bicarbonate correlate negatively with U. The uranium:specific conductance, U:B, and U:SO4 ratios correlate positively with U. Groundwater data indicate the presence of U in a slightly acidic, low salinity hydrogeochemical environment. Stream sediment data (651 samples) indicate that four areas with soluble U values >= 4.13 ppM are present in the central, northwestern, and eastern portions of the survey area. All of these areas are associated with the presence of Precambrian granites. Areas with high total U (U-NT) values are generally coincident with high soluble U trends. Though trace element associations vary for each of the four areas, all are high in Ce, La, Y, and Zr. Soluble U is positively correlated with Y, Zr, Be, Ce, La, Fe, Na, Ba, Ti, Mn, Li, Zn, Pb, Th, Nb, Sc, and V; and it is negatively correlated with Ca, Se, Mg, and B. Th values >= 17 ppM coincide with high U values in three of the four aforementioned areas. Th correlates positively with soluble and total U, the Th/total U ratio, Y, Zr, Be, Ce, La, Na, Ag, and Nb, and negatively with Ca and Mg. A polymetallic association including Cr, Co, Cu, Fe, Ni, Sc, V, and Zn is present in sediment derived from some portions of the Precambrian Llano Supergroup

    varies from strata- to structure-bound and occurs above regional unconformities. The Proterozoic basins in the Mount Isa Inlier rest unconformably on Palaeoproterozoic basement accompanied by volcanic and igneous rocks, which were deformed and metamorphosed in the Mesoproterozoic. Uranium occurrences in the Western Succession of Mount Isa are either hosted in clastic metasediments or mafic volcanics that belong to the Palaeoproterozoic Eastern Creek Volcanics. Uranium and vanadium mineralization occur in metasomatised and hematite-magnetite-carbonate alteration zones, bounded by major faults and regional unconformities. The results of this study highlight the importance of unconformities in uranium minerals systems as possible fluid pathways and/or surfaces of physico-chemical contrast that could have facilitated the precipitation of uranium, not only in classical unconformity style uranium deposits but in several other styles of uranium mineralization as well.

    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.

  13. Uranium enrichment

    International Nuclear Information System (INIS)

    GAO was asked to address several questions concerning a number of proposed uranium enrichment bills introduced during the 100th Congress. The bill would have restructured the Department of Energy's uranium enrichment program as a government corporation to allow it to compete more effectively in the domestic and international markets. Some of GAO's findings discussed are: uranium market experts believe and existing market models show that the proposed DOE purchase of a $750 million of uranium from domestic producers may not significantly increase production because of large producer-held inventories; excess uranium enrichment production capacity exists throughout the world; therefore, foreign producers are expected to compete heavily in the United States throughout the 1990s as utilities' contracts with DOE expire; and according to a 1988 agreement between DOE's Offices of Nuclear Energy and Defense Programs, enrichment decommissioning costs, estimated to total $3.6 billion for planning purposes, will be shared by the commercial enrichment program and the government

  14. The uranium International trade

    The aim of this thesis is the understanding of how the present dynamic of uranium International trade is developed, the variables which fall into, the factors that are affecting and conditioning it, in order to clarify which are going to be the outlook in the future of this important resource in front of the present ecological situation and the energetic panorama of XXI Century. For this purpose, as starting point, the uranium is considered as a strategic material which importance take root in its energetic potential as alternate energy source, and for this reason in Chapter I, the general problem of raw materials, its classification and present situation in the global market is presented. In Chapter II, by means of a historical review, is explain what uranium is, how it was discovered, and how since the end of the past Century and during the last three decades of present, uranium pass of practically unknown element, to the position of a strategic raw material, which by degrees, generate an International market, owing to its utilization as a basic resource in the generation of energy. Chapter III, introduce us in the roll played by uranium, since its warlike applications until its utilization in nuclear reactors for the generation of electricity. Also is explain the reason for this change in the perception at global level. Finally, in Chapter IV we enter upon specifically in the present conditions of the International market of this mineral throughout the trends of supply and demand, the main producers, users, price dynamics, and the correlation among these economical variables and other factors of political, social and ecological nature. All of these with the purpose to found out, if there exist, a meaning of the puzzle that seems to be the uranium International trade

  15. Uranium in South Africa: 1985

    International Nuclear Information System (INIS)

    South Africa's participation in the nuclear industry was limited to the production of uranium and research, with minor commercial activities. The commissioning of the Koeberg Nuclear power station in 1984 placed South Africa firmly on the path of commercial nuclear power generation. A unique, locally developed uranium enrichment process will enable South Africa to be self-sufficient in its nuclear-fuel needs. Uranium has always been of secondary importance to gold as a target commodity in the exploration of the quartz-pebble conglomerates. In the Witwatersrand Basin it is estimated that in excess of R100 million was spent on exploration during 1985. This was spent primarily in the search for gold but as many of the gold reefs are uraniferous, new uranium resources are being discovered concurrently with those of gold. Uranium mineralization is present in rocks which encompass almost the whole of the geological history of South Africa. Significant mineralization is restricted to five fairly well-defined time periods. Each period is characterized by a distinct type or combination of types of mineralization. Resource estimates are divided into separate categories that reflect different levels of confidence in the quantities reported. The resource categories are further separated into levels of exploitability based on the estimated cost of their exploitation. A major part (87%) of South Africa's uranium resources is present as a by-product of gold in the quartz-pebble conglomerates of the Witwatersrand Basin. The uranium resources in the reasonably assured resources (RAR) and estimated additional resources - category I (EAR-I) catogories were 483 300 t U. Production during 1985 was 4880 t U. Although a production peaking at over 1200 t U/a is theoretically attainable, it is considered, from market projections, that a production ceilling of 10 000 t U/a would be more realistic

    Uranium mining and processing constitute the front-end of the nuclear fuel-cycle and respond for most of its radiological impacts. For many years it has been accepted that the key driving force associated with these radiological impacts was related with radon exhalation from mill tailings. However, evidences coming from other mining sites showed that impacts in superficial and ground waters could also play a significant role. In Brazil, the newest uranium production unit presents a unique opportunity to integrate all the above concepts in a logical framework that will lead to sound and environmental balanced operations. The production center (Caetité plant) consists of open pit mine and sulfuric acid Heap Leach operations and is located at a semi-arid region in northeastern Brazil. Because groundwater is the sole perennial source of water for human consumption and industrial use, this resource has to be managed wisely and efficiently. Therefore, this paper intends to summarize the components of an ongoing project of groundwater management in uranium mining areas. The results will guide the adequate management of groundwater use and provide the basis for the appropriate impact assessment of the potential releases of pollutants. The methodology starts with the mathematical simulation of the long-term behavior of the hydrogeological system based on an experimental basin approach. The occurrence and pattern of groundwater flow in the Caetité experimental basin (CEB) are mainly conditioned by the degree of faulting/fracturing of rocks (predominantly gneisses and granites). Two faulting systems are observed in the area, the principal one, parallel to the foliation (with NW direction) and the secondary one with NE direction. The main water reservoirs in the CEB are related to the intrusion of a diabase dike, which increased the density of fractures in the rocks. This dike serves as natural barrier to the water flow and constrains the potential contamination of

    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

  2. Moving to world's best uranium address

    International Nuclear Information System (INIS)

    Most exploration dollars spent in South Australia are focused on exploiting uranium. This is for good reason as South Australia is the world's best address for uranium. Pressure to cut CO2 emissions and the ballistic growth of the Chinese and Indian economies has heightened expectations that the worldwide use of uranium for power generation will mushroom beyond its current 17% market share. The recent Australia-China deal only seems to confirm this; hence uranium's growing popularity among miners and explorers. Such is the attractiveness of uranium-related floats, when Toro Energy sought $18m in March it was swamped with more than three times share application volume. In the north west, Southern Gold and Hindmarsh Resources are expectantly drilling for commercial uranium deposits all around the acreage that hosts the Challenger gold mine in the Gawler Craton. The first exploration drilling for uranium in quaternary-age river channels will take place in South Australia's far north in May. Red Metal says while older and deeper tertiary river channels in the area that host the Beverley uranium mine were explored for uranium, the younger near-surface channel has not had a single hole drilled for uranium. This is despite the area being one of the 'hottest radiogenic terrains in South Australia'. The company will target calcrete-style uranium mineralisation similar to the Yerrlirrie deposit in Western Australia (52,000t U308). Tasman Resources will start drilling to test seven uranium targets within 30km of Olympic Dam, the world's largest known uranium deposit, later this year. Tasman also holds tenements adjoining the Warrior uranium deposit near Tarcoola that contains known radiometric anomalies within the 40km-long Wynbring paleochannels. They are the fourth largest uranium explorer in South Australia. Alliance Resources and its JV partner Quasar Resources are exploring the Beverley 4 Mile uranium prospect at Arkaroola. Quasar is an affiliate of Heathgate Resources

  7. Biotechnology for uranium extraction and environmental control

    International Nuclear Information System (INIS)

    India is looking forward to augmenting mining and extraction of uranium mineral for its nuclear energy needs. Being a radio-active mineral, mining and processing of uranium ore deposits need be carried out in an environmentally acceptable fashion. In this respect, a biotechnological approach holds great promise since it is environment-friendly, cost-effective and energy-efficient. There are several types of microorganisms which inhabit uranium ore bodies and biogenesis plays an important role in the mineralisation and transport of uranium-bearing minerals under the earth's crust. Uranium occurrences in India are only meagre and it becomes essential to tap effectively all the available resources. Uraninite and pitchblende occurring along with sulfide mineralisation such as pyrite are ideal candidates for bioleaching. Acidithiobacillus ferrooxidans present ubiquitously in the ore deposits can be isolated, cultured and utilised to bring about efficient acidic dissolution of uranium. Many such commercial attempts to extract uranium from even lean ores using acidophilic autotrophic bacteria have been made in different parts of the world. Anaerobes such a Geobacter and Sulfate Reducing Bacteria (SRB) can be effectively used in uranium mining for environmental control. Radioactive uranium mined wastes and tailing dumps can be cleaned and protected using microorganisms. In this lecture use of biotechnology in uranium extraction and bioremediation is illustrated with practical examples. Applicability of environment-friendly biotechnology for mining and extraction of uranium from Indian deposits is outlined. Commercial potentials for bioremediation in uranium-containing wastes are emphasised. (author)

  8. Tramp uranium

    International Nuclear Information System (INIS)

    Many utilities have implemented a no leaker philosophy for fuel performance and actively pursue removing leaking fuel assemblies from their reactor cores whenever a leaking fuel assembly is detected. Therefore, the only source for fission product activity in the RCS when there are no leaking fuel assemblies is tramp uranium. A technique has been developed that strips uranium impurities from ZrCl4. Unless efforts are made to remove natural uranium impurities from reactor materials, the utilities will not be able to reduce the RCS specific 131I activity in PWRs to below the lower limit of ∼1.0 x 10-4 μCi/g

    The early 1980s, when I first learned theory, were desperate times for graduate students. We searched frantically for coherent introductions, passing tattered copies of review articles around like samizdat, struggling over obscure references to ancient models of strong interactions, and flocking to lectures—not least those by Joe Polchinski—that promised to really explain what was going on. If only this book had been around, it would have saved much grief. Volume I, The Bosonic String, offers a clear and well organized introduction to bosonic string theory. Topics range from the 'classical' (spectra, vertex operators, consistency conditions, etc.) to the 'modern' (D-branes first appear in an exercise at the end of chapter 1, noncommutative geometry shows up in chapter 8). Polchinski does not hesitate to discuss sophisticated matters—path integral measures, BRST symmetries, etc.—but his approach is pedagogical, and his writing is lucid, if sometimes a bit terse. Chapters end with problems that are sometimes difficult but never impossible. A very useful annotated bibliography directs readers to resources for further study, and a nearly 30-page glossary provides short but clear definitions of key terms. There is much here that will appeal to relativists. Polchinski uses the covariant Polyakov path integral approach to quantization from early on; he clearly distinguishes Weyl invariance from conformal invariance; he is appropriately careful about using complex coordinates on topologically nontrivial manifolds; he keeps the string world sheet metric explicit at the start instead of immediately hiding it by a gauge choice. Volume II includes an elegant introduction to anticommuting coordinates and superconformal transformations. A few conventions may cause confusion—%, Polchinski's stress energy tensor, for instance, differs from the standard general relativistic definition by a factor of -2π, and while this is briefly mentioned in the text, it could easily be

In September 1999, Slovenia also joined the international agreement on the protection of copyrights. It is expected that electronic books will gradually become part of the collection of all types of libraries. Therefore, libraries will need appropriate technical equipment as well as trained personnel for the usage of this new medium.

  12. Uranium in South Africa: 1987

    International Nuclear Information System (INIS)

    South Africa's participation in the nuclear industry was limited to the production of uranium and research, with minor commercial activities. The commissioning of the Koeberg Nuclear power station in 1984 placed South Africa firmly on the path of commercial nuclear power generation. A unique locally developed uranium enrichment process wil enable South Africa to be self-sufficient in its nuclear-fuel needs. Uranium has always been of secondary importance to gold as a target commodity in the exploration of the quartz-pebble conglomerates. In the Witwatersrand Basin it is estimated that in excess of R300 million was spend on exploration during 1987. This was spend primarily in the search for gold but as many of the gold reefs are uraniferous, new uranium resources are being discovered concurrently with those of gold. Uranium mineralization is present in rocks which encompass almost the whole of the geological history of South Africa. Significant mineralization is restricted to five fairly well-defined time periods. Each period is characterized by a distinct type or combination of types of mineralization. Resource estimates are divided into separate categories that reflect different levels of confidence in the quantities reported. The resource categories are further separated into levels of exploitability based on the estimated cost of their exploitation. A major part (87%) of South Africa's uranium resources is present as a by-product of gold in the quartz-pebble conglomerates of the Witwatersrand Basin. The uranium resources in the RAR and EAR-I categories were 536 500 t u. Production during 1987 was 3963 t u. Although a production peaking at over 1100 t U/a is theoretically attainable, it is considered, from market projections, that a production ceiling of 10 000 t U/a would be more realistic

  13. Uranium in Mongolia

    International Nuclear Information System (INIS)

    Full text: Mongolian electricity is produced from fossil fuels (about 98%, mainly coal). Rapid growth in demand has given rise to power shortages, and the reliance on fossil fuels has led to much air pollution. Mongolia does not have nuclear reactor and thus is not a beneficiary of nuclear technology. In April 2008 Russia and Mongolia signed a high-level agreement to cooperate in identifying and developing Mongolia's uranium resources. Russia is also examining the feasibility of building nuclear power plants in Mongolia In our government need to create the environment for investment in nuclear power, including professional regulatory regime, policies on nuclear waste management and decommissioning, and involvement with international non-proliferation and insurance arrangements. Some 46 million kilowatt-hours of electricity are produced from one tones of natural uranium. The production of this amount of electrical power from fossil fuels would require the burning of over 20 000 tonnes of black coal or 8.5 million cubic meters of gas. Mongolia has a long history of uranium exploration commencing with joint Russian and Mongolian endeavors to 1957. Today the Canada-based Khan Resources owns a 69% share in the Dornod project through its subsidiary Central Asian Uranium Co. Ltd and Russia's Priargunsky Mining and Chemical Enterprise owns a further share. In 2007 Khan published NI 43-101 compliant indicated resource figure of 25 000 tU for the project, including probable reserves of 7 000 tU. A bankable feasibility study is now being undertaken, with capital cost estimate being US$283 million and first production in 2011. Khan has applied for a mining licence from the Mineral Resources and Petroleum Authority of Mongolia (MRPAM). (author)

    In recent years, there has been a growing resurgence of interest in the philosophical views of the founders of quantum mechanics. Kristian Camilleri's book on Werner Heisenberg's philosophy of quantum mechanics is a welcome addition to this literature. It takes Heisenberg seriously as a philosopher of science, traces the various philosophical influences on his view, and carefully distinguishes his interpretation of quantum mechanics from that of his contemporaries. It is a fine example of the new insights that can emerge when one takes an integrated approach to the history and philosophy of science. After summarizing some of the main themes of the book, I will turn to two moderate criticisms of the book-one stylistic, and the other, regarding its content.

  18. Domestic utility attitudes toward foreign uranium supply

    Energy Technology Data Exchange (ETDEWEB)

    1981-06-01

    The current embargo on the enrichment of foreign-origin uranium for use in domestic utilization facilities is scheduled to be removed in 1984. The pending removal of this embargo, complicated by a depressed worldwide market for uranium, has prompted consideration of a new or extended embargo within the US Government. As part of its on-going data collection activities, Nuclear Resources International (NRI) has surveyed 50 domestic utility/utility holding companies (representing 60 lead operator-utilities) on their foreign uranium purchase strategies and intentions. The most recent survey was conducted in early May 1981. A number of qualitative observations were made during the course of the survey. The major observations are: domestic utility views toward foreign uranium purchase are dynamic; all but three utilities had some considered foreign purchase strategy; some utilities have problems with buying foreign uranium from particular countries; an inducement is often required by some utilities to buy foreign uranium; opinions varied among utilities concerning the viability of the domestic uranium industry; and many utilities could have foreign uranium fed through their domestic uranium contracts (indirect purchases). The above observations are expanded in the final section of the report. However, it should be noted that two of the observations are particularly important and should be seriously considered in formulation of foreign uranium import restrictions. These important observations are the dynamic nature of the subject matter and the potentially large and imbalanced effect the indirect purchases could have on utility foreign uranium procurement.

  19. Current situation and problems to be studied for uranium bearing coal deposit mining in China

    International Nuclear Information System (INIS)

    Uranium bearing coal deposits are a specific kind of uranium ore resources. Since uranium bearing coal can generate electricity, provide heat and recover uranium during the process of hydrometallurgy, it is necessary to mine these deposits. This paper summarizes the experiences in uranium bearing coal deposit mining, suggests research topics in this area. It is hoped that these studies can promote the development of uranium bearing coal deposit mining. (authors)

  20. Uranium prospection in Venezuela

    International Nuclear Information System (INIS)

    Full text: The worldwide increase of energy consumption and high fossil fuels costs generates the necessity of alternative energy sources. At present, nuclear energy is substituting the use of hydrocarbons, due to its high performance and contribution to environmental preservation, since it avoids the emission of greenhouse gases. Uranium consumer countries will continue to increase its demand, and even, is expected the incorporation of new reactors in countries with emerging economies. Base in the statement considered above, investment in new mineral deposit is justified. At present, some countries are motivated to start or continue the uranium exploration because of the evolution of the nuclear energy industry. Venezuela started exploration in the mid of 1970s, and stopped at 1980s. Our purpose is to evaluate uranium resources potential in the country, both for own use or export. In order to locate potential areas for exploration, in this initial phase all data from previous period is being compiled, incorporating information from oil exploration (seismic data, wells profiles, etc.). This information is been digitalized to generate a database into a geographical information system. Preliminary results show three areas of interest, where new geological, geochemical and geophysical surveys are propose. At this time, we do not have specific information about ore reserves, but we have anomalous areas that have been established as starting points to continue the uranium exploration in the country.

  1. Uranium enrichment

    International Nuclear Information System (INIS)

    Canada is the world's largest producer and exporter of uranium, most of which is enriched elsewhere for use as fuel in LWRs. The feasibility of a Canadian uranium-enrichment enterprise is therefore a perennial question. Recent developments in uranium-enrichment technology, and their likely impacts on separative work supply and demand, suggest an opportunity window for Canadian entry into this international market. The Canadian opportunity results from three particular impacts of the new technologies: 1) the bulk of the world's uranium-enrichment capacity is in gaseous diffusion plants which, because of their large requirements for electricity (more than 2000 kW·h per SWU), are vulnerable to competition from the new processes; 2) the decline in enrichment costs increases the economic incentive for the use of slightly-enriched uranium (SEU) fuel in CANDU reactors, thus creating a potential Canadian market; and 3) the new processes allow economic operation on a much smaller scale, which drastically reduces the investment required for market entry and is comparable with the potential Canadian SEU requirement. The opportunity is not open-ended. By the end of the century the enrichment supply industry will have adapted to the new processes and long-term customer/supplier relationships will have been established. In order to seize the opportunity, Canada must become a credible supplier during this century

    has lavished on this set, which is an important monument and reference but presumably not a moneymaker. Every university library must buy it, but probably few individuals will, at least not in the near term when most of those with the seniority (i.e., cash) to make the purchase already own, or have read, the Les Houches lectures. What remains to be seen is to what extent a later generation will discover it as a valuable resource. Parts I and II develop the basic classical and quantum kinematics of fields and other dynamical systems. The presentation is conducted in the utmost generality, allowing for dynamical quantities that may be anticommuting (supernumbers) and theories subject to the most general possible gauge symmetry— in fact, such symmetries are called 'invariant flows' to emphasize that they may not form a gauge group in the conventional sense. The basic ingredients are action functionals and the Peierls bracket, a manifestly covariant replacement for the Poisson bracket and equal-time commutation relations. Nothing was more central to the DeWitt gospel than these, and the book begins with a paragraph of condemnation of Hamiltonians and canonical formulations with constraints as dysfunctional nineteenth-century baggage. For DeWitt the logical progression is Peierls bracket → Schwinger action principle → Feynman functional integral although he points out that the historical development was in the opposite order. The word 'global' in the title, presumably chosen to avoid duplicating the second Les Houches lectures, refers to this overall framework.The word is somewhat misleading, since in many respects DeWitt's work entails a concentration on local over global quantities. For example, chapter 2 states forcefully that local gauge symmetries are both more fundamental and more ubiquitous than global symmetries. It must be pointed out that the Peierls Schwinger DeWitt approach, despite some advantages over initial-value formulations, has some troubles of its

    This book represents the proceedings of the five day programme on IMRT techniques presented at the 2003 American Association of Physicists in Medicine (AAPM) Summer School held in Colorado Springs, Colorado. The book is essentially an overview of IMRT techniques, discussing the history, the mathematical processes involved in the planning stages, the biological indices for evaluations, the off-line and on-line medical imaging that is required, the various IMRT delivery techniques available, positioning and motion verification, shielding and QA issues, and some clinical applications. There is some additional discussion on modulated electron and proton therapy, views on the clinical and financial impact of IMRT, as well as some speculation on the future uses of IMRT. The fact that the book is an `overview' must be emphasized. Medical physicists who are well-read in IMRT, or have implemented IMRT, even partially, may be a little disappointed with the book. Although specific details were purposely omitted, the well-read physicist would have preferred to go right to the `heart of the matter', something this book fails to do. As is typical of many proceedings-type books, there is a certain level of inconsistency of writing styles, as well as some redundancy between the different chapters. It is unfortunate that such a large volume does not have an index to allow a reader to explore a particular subject pertaining to IMRT. The reader would have to guide himself/herself by the table of contents before each chapter which could be a problem if the reader requires some information quickly. It is interesting to note that the book lends itself to a variety of professionals interested in IMRT, including administrators. It may be a source of help for medical physicists who wish to discuss IMRT issues with higher level administration, for example. Some clinical applications are also reviewed. The lack of details concerning the advantages of IMRT with respect to clinical outcome is

    International Nuclear Information System (INIS)

    Uranium has been in use in Europe since the Middle Ages, and working of uraniferous minerals on an industrial scale for the production of radium began in Portugal and Czechoslovakai in 1904. Mining began soon after World War II for the production of fissile material. Western Europe's uranium resources represent about a tenth of the world's resources, of 486 950 tonnes recoverable at $130 per kg or less. Production in 1978 was 2 513 tonnes of uranium. The principal producing countries were the Federal Republic of Germany, Spain, France, and Portugal. Uraniferous vein deposits occur in the Moldanubian granites, the Iberian Meseta, the Armorican massif, the Massif Central, and the Black Forest. Deposits associated with sedimentary rocks occur in the Cambrian shales of Ranstad, the Permian lutites and silts of Lodeve, and in grits and sandstones elsewhere. Volcanic deposits are present in Alpine areas. The current rate of exploration must be maintained if the energy needs of Europe predicted for the year 2000 are to be met. (L.L.)

  10. World uranium supply and demand

    International Nuclear Information System (INIS)

    The role of nuclear energy is under increasing scrutiny and uncertainty. None the less, there will be an increasing need for expansion of uranium supply to fuel committed reactors. Longer-term demand projections are very uncertain. Improved knowledge of the extent of world resources and their availability and economics is needed to support planning for reactor development, especially for breeder reactors, and for fuel-cycle development, especially enrichment, and reprocessing and recycle of uranium and plutonium. Efforts to date to estimate world uranium resources have been very useful but have largely reflected the state of available knowledge for the lower cost resources in regions that have received considerable exploration efforts. The IUREP evaluation of world resources provides an initial speculative estimate of world resources, including areas not previously appraised. Projections of long-range supply from the estimated resources suggest that the high-growth nuclear cases using once-through cycle may not be supportable for very long. However, additional effort is needed to appraise and report more completely and consistently on world resources, the production levels attainable from these resources, and the economic and price characteristics of such production.

    Uranium-bearing hydrothermal solutions during the stage of ore deposition are weakly alkaline and of the Ca2+ -Na+/HCO3- -F- type.UO2(CO3)22- and UO2F4-, are dominant in the hydrothermal solutions with respect to their activity.Wall-rock hydrothermal alterations ,temperature and pressure drop and the reducing capability of rock assemblage (Δeh) led to a decrease in Eh of the hydrothermal solutions and an increase in Eh at which uranium began precipitating.Therefore,the mechanism of uranium precipitation is essentially the reduction of uranium complexes.The granite-type uranium deposits are the most important type of uranium resources in China.Discussions will be made in this paper concerning the hydrothermal speciation and precipitation mech-anisms of uranium complexes in the light of fluid inclusion and geological data from some major de-posits of this type in South China.

    Most of us sometimes have to face a student asking: 'What do I need to get started on this'. (In my case 'this' would typically be a topic in general relativity.) After thinking about it for quite a while, and consulting candidate texts again and again, a few days later I usually end up saying: read this chapter in book I (but without going too much detail), then that chapter in book II (but ignore all those comments), then the first few sections of this review paper (but do not try to work out equations NN to NNN), and then come back to see me. In the unlikely event that the student comes back without changing the topic, there follows quite a bit of explaining on a blackboard over the following weeks. From now on I will say: get acquainted with the material covered by this book. As far as Isham's book is concerned, 'this' in the student's question above can stand for any topic in theoretical physics which touches upon differential geometry (and I can only think of very few which do not). Said plainly: this book contains most of the introductory material necessary to get started in general relativity, or those branches of mathematical physics which require differential geometry. A student who has mastered the notions presented in the book will have a solid basis to continue into specialized topics. I am not aware of any other book which would be as useful as this one in terms of the spectrum of topics covered, stopping at the right place to get sufficient introductory insight. According to the publisher, these lecture notes are the content of an introductory course on differential geometry which is taken by first-year theoretical physics PhD students, or by students attending the one-year MSc course 'Quantum Fields and Fundamental Forces' at Imperial College, London. The volume is divided into six chapters: An Introduction to Topology Differential Manifolds Vector Fields and n-Forms Lie Groups Fibre Bundles Connections in a Bundle.

Phosphate rock has been the most suitable alternative source for the uranium recovery because of its uranium content. Solvent extraction has been found to...

    Thanks to its impressive success in the second half of the 20th century, both in high-energy physics and in critical phenomena, quantum field theory has enjoyed an abundant literature. We therefore greet yet another book on this subject with caution: what can a monograph on quantum field theory bring now that is new, either conceptually or pedagogically? But when it is written by a physicist such as Bryce DeWitt, who has made his own contribution to the collection of field theory books with The Global Approach to Quantum Field Theory, all suspicion is naturally abandoned. One knows in advance that this book can only lead to a genuine enrichment of the literature. DeWitt has made a formidable contribution to various areas of physics: general relativity, the interpretation of quantum mechanics, and most of all the quantization of non-Abelian gauge theories and quantum gravity. In addition, his pedagogical publications, especially the Les Houches schools of 1963 and 1983 [1, 2], have had a great impact on quantum field theory. All this makes the reader keen to pick up his new work and a deeper reading confirms the reviewer's initial enthusiasm. We must begin by alerting the potential readers of this book that it cannot be compared to any other book in the field (unless of course we are talking about references [1] and [2], of which the book under review is an extension and reworking). This uniqueness applies to both the scientific content and the way the ideas are presented. A quick description of this book and a brief explanation of its title should convince the reader of the book's unique quality. For DeWitt, a central concept of field theory is that of `space of histories'. For a field varphii defined on a given spacetime M, the set of all varphii(x) for all x in all charts of M defines its history. It is the space Phi of all possible histories (dynamically allowed or not) of the fields defined on M which is called the `space of histories' by DeWitt. If only

    Quantum Noise is advertised as a handbook, and this is indeed how it functions for me these days: it is a book that I keep within hand's reach, ready to be consulted on the proper use of quantum stochastic methods in the course of my research on quantum dots. I should point out that quantum optics, the target field for this book, is not my field by training. So I have much to learn, and find this handbook to be a reliable and helpful guide. Crispin Gardiner previously wrote the Handbook of Stochastic Methods (also published by Springer), which provides an overview of methods in classical statistical physics. Quantum Noise, written jointly with Peter Zoller, is the counterpart for quantum statistical physics, and indeed the two books rely on each other by frequent cross referencing. The fundamental problem addressed by Quantum Noise is how the quantum dynamics of an open system can be described statistically by treating the environment as a source of noise. This is a general problem in condensed matter physics (in particular in the context of Josephson junctions) and in quantum optics. The emphasis in this book in on the optical applications (for condensed matter applications one could consult Quantum Dissipative Systems by Ulrich Weiss, published by World Scientific). The optical applications centre around the interaction of light with atoms, where the atoms represent the open system and the light is the noisy environment. A complete description of the production and detection of non-classical states of radiation (such as squeezed states) can be obtained using one of the equivalent quantum stochastic formulations: the quantum Langevin equation for the field operators (in either the Ito or the Stratonovich form), the Master equation for the density matrix, or the stochastic Schrödinger equation for the wave functions. Each formulation is fully developed here (as one would expect from a handbook), with detailed instructions on how to go from one to the other. The

    Firstly, with emphasis on in-situ leachable sandstone-type uranium deposits, the prospecting history of uranium deposits worldwide and its scientific research development are generally reviewed in four steps, and their basic historical experience is also summarized. Secondly, based on the detailed description of current development status of uranium geology of foreign in-situ leachable sandstone-type uranium deposits the important strategic position of sandstone-type uranium deposits in overall uranium resources all-over-the-world and its classification, spatial-temporal distribution and regulation, and metallogenic condition of sandstone-type uranium deposits are analysed thoroughly in five aspects: techtonics, paleo-climate, hydrogeology, sedimentary facies and lithology, as well as uranium sources: Afterwards, evaluation principles of three type of hyper-genic, epigenetic infiltrated sandstone-type uranium deposits are summarized. Based on sandstone-type uranium deposits located two important countries: the United States and Russia, the current development status of prospecting technology for in-situ leachable sandstone-type uranium deposits in foreign countries is outlined. Finally, according to the prospects of supply-demand development of global uranium resources, the author points out seriously that Chinese uranium geology is faced with a severe challenge, and proposes directly four strategic measures that should be taken

  13. Technique for recovering uranium from sludge-like uranium-bearing wastes using hydrochloric acid

    International Nuclear Information System (INIS)

    Sludge-like uranium-bearing wastes generated from uranium refining and conversion R and D facilities are stored at the Ningyo-toge Environmental Engineering Center of the Japan Atomic Energy Agency. So far, approximately 1500 t of uranium wastes with radioactivity levels exceeding 10,000 Bq/g have been generated. We have proposed an environmentally benign aqueous process for recovering uranium from wastes using hydrochloric acid (HCl). This makes it possible to dispose of the wastes easily, and to reclaim uranium as a resource. In this process, first, the uranium content in the calcium fluoride (CaF2) sludge along with the entire sludge is dissolved almost completely in aqueous solutions containing HCl and aluminum chloride. The uranium species are then recovered as peroxide from the CaF2 sludge solution. Their characteristics are similar to those specified for uranium ore concentrate. After recovering the uranium content, the uranium concentration in the solution is reduced to below 0.01 mg/L using an iminodiacetic chelating resin. Also, the uranium concentration of the precipitate generated by the neutralization of the barren solution falls below 1 Bq/g. (author)

    Networks have been recently recognized as playing a central role in understanding a wide range of systems spanning diverse scientific domains such as physics and biology, economics, computer science and information technology. Specific examples run from the structure of the Internet and the World Wide Web to the interconnections of finance agents and ecological food webs. These networked systems are generally made by many components whose microscopic interactions give rise to global structures characterized by emergent collective behaviour and complex topological properties. In this context the statistical physics approach finds a natural application since it attempts to explain the various large-scale statistical properties of networks in terms of local interactions governing the dynamical evolution of the constituent elements of the system. It is not by chance then that many of the seminal papers in the field have been published in the physics literature, and have nevertheless made a considerable impact on other disciplines. Indeed, a truly interdisciplinary approach is required in order to understand each specific system of interest, leading to a very interesting cross-fertilization between different scientific areas defining the emergence of a new research field sometimes called network science. The book of Dorogovtsev and Mendes is the first comprehensive monograph on this new scientific field. It provides a thorough presentation of the forefront research activities in the area of complex networks, with an extensive sampling of the disciplines involved and the kinds of problems that form the subject of inquiry. The book starts with a short introduction to graphs and network theory that introduces the tools and mathematical background needed for the rest of the book. The following part is devoted to an extensive presentation of the empirical analysis of real-world networks. While for obvious reasons of space the authors cannot analyse in every detail all the

    General relativity is one of the cornerstones of modern physics. In spite of this, the teaching of general relativity at undergraduate level remains quite marginal. The reasons for this particular situation are quite well known. We can quote, for example, two of them: general relativity requires specific mathematical tools that are somehow outside the mainstream of undergraduate technical development; moreover, this is a branch of physics whose observational and experimental applications have remained rare until recent times, and even though this scenario has changed dramatically in the last few years, the new situation has not yet been absorbed into undergraduate teaching. However, there are many textbooks devoted to the teaching of general relativity at undergraduate level. The recent book of J B Hartle, Gravity: An Introduction to Einstein's General Relativity, is a new proposal in this sense. It is perhaps one of the most interesting pedagogical approaches seeking to surmount the difficulties that arise when one tries to include general relativity in undergraduate teaching. In this new book, Hartle attempts to address the difficuties that must be faced by anyone who teaches general relativity at undergraduate level. In order to not scare the student with the hard technical preparation needed to obtain the basic equations of general relativity, Einstein's equations, he simply gives up the idea of introducing these equations at the very beginning. Instead, he chooses to present Einstein's equations, with most of the mathematics needed to do them, in the last part of the book. This delicate (and of course dangerous) choice has the advantage of introducing the reader first to the physical aspects of general relativity. This approach can be dangerous because the relevant solutions of the equations necessary to discuss the physical content of general relativiy are presented first without a formal derivation. But the author circumvents this potential drawback in a

    Ever since the days of William Blake there has been an underground resistance against the soulless yet triumphant science and its unholy alliance with money, technology and political power. With the nearly undisputed hegemony that science and technological innovation has attained in the post-World War II era, this kind of resistance has resulted in numerous books and articles that in different ways warn against the dark sides of science and the socio-economic system that nourishes a science in degeneration. Classical examples include Herbert Marcuse's One-Dimensional Man (1964), Jacques Ellul's The Technological Society (1965), Theodore Roszak's The Making of a Counter Culture (1968), and Paul Feyerabend's Science in a Free Society (1978). A fair part of the literature written by sociologists and philosophers is not only critical to trends in modern science, but tends to or is overtly anti-science. The book under review belongs in some respects to this heterogeneous literary tradition, but Twilight of the Scientific Age is primarily directed against the institutional system of science and its associated ideology and not against science itself. Indeed, the author is himself a practicing scientist, an astrophysicist, and he emphasizes several times that he firmly believes in science, even that he loves it. He is not a "stupid cultural relativist," he asserts (p. 11), but a critical freethinker independent of dogmatic beliefs.

    This paper reports that in 1990 the Department of Energy began a two-year project to illustrate the technical and economic feasibility of a new uranium enrichment technology-the atomic vapor laser isotope separation (AVLIS) process. GAO believes that completing the AVLIS demonstration project will provide valuable information about the technical viability and cost of building an AVLIS plant and will keep future plant construction options open. However, Congress should be aware that DOE still needs to adequately demonstrate AVLIS with full-scale equipment and develop convincing cost projects. Program activities, such as the plant-licensing process, that must be completed before a plant is built, could take many years. Further, an updated and expanded uranium enrichment analysis will be needed before any decision is made about building an AVLIS plant. GAO, which has long supported legislation that would restructure DOE's uranium enrichment program as a government corporation, encourages DOE's goal of transferring AVLIS to the corporation. This could reduce the government's financial risk and help ensure that the decision to build an AVLIS plant is based on commercial concerns. DOE, however, has no alternative plans should the government corporation not be formed. Further, by curtailing a planned public access program, which would have given private firms an opportunity to learn about the technology during the demonstration project, DOE may limit its ability to transfer AVLIS to the private sector

    It is not usual for someone to write a book on someone else's Ph.D. thesis, but then Feynman was not a usual physicist. He was without doubt one of the most original physicists of the twentieth century, who has strongly influenced the developments in quantum field theory through his many ingenious contributions. Path integral approach to quantum theories is one such contribution which pervades almost all areas of physics. What is astonishing is that he developed this idea as a graduate student for his Ph.D. thesis which has been printed, for the first time, in the present book along with two other related articles. The early developments in quantum theory, by Heisenberg and Schrödinger, were based on the Hamiltonian formulation, where one starts with the Hamiltonian description of a classical system and then promotes the classical observables to noncommuting quantum operators. However, Dirac had already stressed in an article in 1932 (this article is also reproduced in the present book) that the Lagrangian is more fundamental than the Hamiltonian, at least from the point of view of relativistic invariance and he wondered how the Lagrangian may enter into the quantum description. He had developed this idea through his 'transformation matrix' theory and had even hinted on how the action of the classical theory may enter such a description. However, although the brief paper by Dirac contained the basic essential ideas, it did not fully develop the idea of a Lagrangian description in detail in the functional language. Feynman, on the other hand, was interested in the electromagnetic interactions of the electron from a completely different point of view rooted in a theory involving action-at-a-distance. His theory (along with John Wheeler) did not have a Hamiltonian description and, in order to quantize such a theory, he needed an alternative formulation of quantum mechanics. When the article by Dirac was brought to his attention, he immediately realized what he was

  10. Canada's uranium industry - the next decade

    International Nuclear Information System (INIS)

    Uranium is a unique commodity. It is both a metal and a fuel. It has both commercial and military uses. It yields 'clean energy' but presents environmental concerns. All of these factors have an impact on the commerce of uranium. Being a metal, uranium is extracted from ore like many other metallic minerals. As a fuel, it is subject to the vagaries of energy commodity market forces. The history of uranium in the first nuclear weapons has led to national governments carefully controlling production and sale of uranium. The spectre of radioactive contamination of the environment adds further to the public concern over the disposal of low-level radioactive wastes from uranium processing and use. There have been a number of excellent reviews on the commercial aspects of the uranium industry. In this discussion, these aspects will be briefly summarized to provide a general picture of the strengths of the Canadian uranium industry and the pressures to which it is being subjected currently. The principal thrust of this paper will be to outline Canada's resource strength and to identify some factors which will affect Canada's ability to continue holding a sizeable share of the world uranium market

    This book achieves what its subtitle indicates. The author skilfully weaves together the story of Bragg's life and of the scientific developments with which he was most closely involved. The author has a good understanding of Bragg's scientific work which he explains in considerable detail, with a number of diagrams reproduced from Bragg's papers, and manages to convey the excitement generated by Bragg's discoveries. The salient points of Bragg's life are well known. He was born and brought up in Australia and is still the youngest ever winner of a Nobel prize (though Josephson did his seminal work at a comparable age, it took many years for him to get his Prize). From 1914 to 1918 Bragg was involved with acoustic methods of detecting enemy guns. From 1919 to 1938 he was Professor of Physics in Manchester, and for about a year he was Director of the National Physical Laboratory. He then went to Cambridge as Cavendish Professor until 1953, when he moved to the Royal Institution (where his father had been). While an undergraduate at Cambridge 'Bragg's most influential teacher was...C T R Wilson [Nobel Laureate, 1927]...[whose] lectures "were the best, and delivery the worst, of any lectures to which I have ever been. He mumbled facing the board, he was very hesitant in his delivery, and yet the way he presented the subject was quite brilliant'' '. One wonders how long Wilson's inspirational teaching would survive today, with continual inspections and the requirement to satisfy the demands of the jobsworths. Bragg's comments on this would make interesting reading! Bragg was a very successful public lecturer on science. He made use of vivid analogies, many of which are quoted by Hunter. Since this book is published by Oxford University Press, I hope that some of them may appear in future editions of The Oxford Dictionary of Quotations. (Bragg is included in Mackay's A Dictionary of Scientific Quotations (Bristol: Institute of Physics Publishing)). There are too many

  12. Australia's uranium policy: an examination

    International Nuclear Information System (INIS)

    The mining and export of Australian Uranium poses problems for the safety of the world that any responsible government is bound to consider. The following note lists the major problems, attempts to assess their importance, and to suggest what lines may be relevant to Australia for their solution. These problems were examined because of the concern about the appropriateness of attempting to fulfill projected world energy needs by any means; and their fulfillment, by using nuclear fuels carries special problems of biological, social and political hazards. Any development of Australia's uranium resources should be considered in this light. (author)

    This second edition of the popular book written by Quang Ho-Kim, Narenda Kumar and Chi Sing Lam, provides a comprehensive and interesting view of ten important topics in modern physics. All the sections have been updated: symmetry, lasers, superconductivity, chaos and fractals, stellar evolution, elementary particles and cosmology, while three new sections have been added to this edition: Bose-Einstein condensates, nanostructures and quantum computation. It is an impressive feat by the authors to cover such a wide panorama of physics from particles to cosmos and at a consistently high scientific level of information and explanation. This level is excellent and is at the frontier of current research but it does mean that some parts may be quite difficult for the undergraduate student. The ideal reader is probably the mature physicist revisiting familiar lines of thought, and following amazing bridges between distant topics. And if you are an active specialist in one particular topic, this book would give a clear insight on subjects outside your own field, allowing you to at last understand what your university colleague is really doing in a branch of physics with which you are totally unfamiliar. At the beginning, the style of writing can be disconcerting at this scientific level; equations are almost systematically avoided and illustrations are sparse, which can occasionally make the discussions rather ponderous, but the remarkable level of pedagogy and imaginative conception more than compensates for this. The fundamental ideas of exciting natural phenomena are elegantly discussed, while the authors never forget that physics is an experimental science, and address up-to-date applications in this manner. A brief bibliography is added at the end of each chapter, and a few simple exercises are given with answers. But the great strength of this book, and the main reason why it is worth reading by anyone interested in modern science, lies in the text itself which

    These colloquium proceedings will be valuable, the blurb says, for graduate students and researchers in cosmology and theoretical astrophysics. Specifically, the book 'looks at both the strengths and weaknesses of the current big bang model in explaining certain puzzling data' and gives a 'comprehensive coverage of the expanding field of cosmology'. The reality is rather different. Conference proceedings rarely compare in value with a solid monograph or good review articles, and Current Issues in Cosmology is no exception. The colloquium was convened by the two editors, who have both long harboured doubts about the big bang, and was held in Paris in June 2004. The proceedings contain 19 presented papers and relatively brief summary comments by four panel speakers. The questions and answers at the end of each talk and a general discussion at the end were recorded and transcribed but contain little of interest. The nature of the colloquium is indicated by panellist Francesco Bertola's comment: 'While in the 1950s it was possible to speak of rival theories in cosmology, now the big-bang picture has no strong rivals. This is confirmed by the fact that out of 1500 members of the IAU Division VIII (Galaxies and the Universe) only a dozen, although bright people, devote their time to the heterodox views.' This was largely a platform for them to give their views. At least half of the dozen, all the 'usual suspects', were present: Geoffery and Margaret Burbidge, Jayant Narlikar, Halton Arp, Chandra Wickramasinghe and, in spirit only but playing a role somewhat like the ghost of Hamlet's father, the late Fred Hoyle. Doubters presented 12 of the 19 papers. Orthodoxy should certainly be challenged and the sociology of science questioned, but I found two main problems with this book. The papers putting the orthodox view are too short, even perfunctory. The most that a serious graduate student would get out of them is a reference to a far better review article or book on modern

    The Polish physicist Józio (Joseph, Josh, Jo) Rotblat was catapulted into the public eye when he (and the 'Pugwash Conferences' organization) received the 1995 Nobel Peace Prize. His life prior to that had been most distinguished but conducted well out of the public eye. Born and raised as a Jewish physicist in pre-World War II Poland, and thus potentially educationally disadvantaged, he battled away for education and scientific achievement. He came to Liverpool University just before the outbreak of World War II, worked in James Chadwick's laboratory on the early beginnings of neutron fission physics, moved to Los Alamos to take part in the US-UK collaborative Manhattan Project to build a nuclear bomb and was motivated by a desire to rid Poland of Nazi 'racial cleansing'. On realizing the US-UK goal was somewhat wider, he resigned this work and dedicated his life to the peaceful uses of radiation and the campaigns to rid the world of the potential world-eliminating possibility of nuclear war. For this purpose he interacted with Albert Einstein and Bertrand Russell, and in July 1957 founded the 'Pugwash Conferences', named for a small fishing village in Nova Scotia, Canada where the first was held. Along the way his personal life was no less dramatic. Cruel events conspired, and his wife Tola remained in Poland and was killed in the Nazi extermination camp at Majdanek. He grieved for his beloved Poland and those left behind or unaccounted for. He was suspected by some Americans of being a spy and had his personal papers and family artefacts impounded. After the war he was Professor of Medical Physics at St Bartholomew's Hospital, London for 30 years up to retirement. After John Roberts, he was the second editor of this journal Physics in Medicine and Biology from 1961-72 (see e.g. Bob Burns' paper in our 50th birthday issue, 2006.

    International Nuclear Information System (INIS)

    This report presents preliminary results of stream sediment and ground water reconnaissance in the Charlotte National Topographic Map Series (NTMS) 10 x 20 quadrangle. Stream sediment samples were collected from small streams at 1254 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 759 sites for a nominal density of one site per 25 square kilometers (ten squre miles). Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Statistical summaries of data and a brief description of results are given. A generalized geologic map and a summary of the geology of the area are included. Key data are presented in page-sized hard copy. Supplementary data are on microfiche. Key data from stream sites include (1) water quality measurements (pH, conductivity, and alkalinity), (2) elements that may be related to potential uranium and thorium mineralization in this area (U, Th, Hf, Ce, and Dy), and (3) elements useful for geologic classification of the sample area (Ti, V, Fe, Mn, Al, and Sc). Supplementary data from stream sites include sample site descriptors (stream characteristics, vegetation, stream width, etc.) and additional elemental analyses that may be useful (F, Eu, Sm, La, Yb, and Lu). Key data from ground water sites include (1) water chemistry measurements (pH, conductivity, and alkalinity) and (2) elemental analyses (U, Na, Cl, Mg, Al, Mn, Br, V, and F).

  4. Uranium exploration in Ethiopia

    International Nuclear Information System (INIS)

    Full text: Radioactive exploration dates back to 1955 and since then little progress has been made. Few pits and trenches in some places show radioactive anomalies.The Wadera radioactive anomaly occurs within the lower part of Wadera series, Southern Ethiopia. As observed from a trench the anomalous bed has a thickness of 0.9-1.2 m and is made of reddish-grey thin bedded sandstones.The presence of Xenotime in arkosic sandstone points to the sedimentary origin of mineralization. It was noticed that the sandstone in the lower part of Wadera series has at places a radioactivity 2-3 times higher than adjacent gneisses. The presence of a placer of such a type in the Wadera series is probably a clue for the existence of larger deposits in the area. In 2007 geological, geochemical and geophysical surveys were conducted to identify and delineate Uranium mineralization in three localities(Kuro, Kalido and Gueti) of Werri area, southern Ethiopia. Kaolinization, silicification, epidotization and chloritization are the main types of alteration associated with different units in the area. Uranium-bearing grains which are hosted in pegmatite veins and associated with magnetite/or ilmenite were observed in the three localities. Geochemical exploration accompanied by geological mapping and radiometric survey was done by employing heavy mineral concentrate, soil, chip and trench channel sampling. Radiometric readings of total count, U,Th and K were taken using GAD-6.Soil and trench geochemical samples of the localities analyzed by ICP-MS have shown 0.1 to 3.8 ppm and 3.9 to 147 ppm Uranium and 3.5 to 104.7 ppm and 3.9 to 147ppm Thorium respectively. Radiometric reading is higher in pegmatite veins that host Uranium-bearing minerals and some course grained pegmatoidal granite varieties. The areas recognized for Uranium associations need further investigations using state-of-the-art to discover economic deposits for development and utilization of the resource. (author)

    Qing Dynasty Archives On the Dalai lamasThe Dalai Lama was one of the two leaders of the Gelug (Yellow) Sect of Tibetan Buddhism. It won the honorific title of the Dalai lama in 1653 from Qing Emperor Shunzhi, and the Living Buddha had since been following the reincarnation system under the supervision of the Central Government. His soul boy was not legal until he won the confirmation of the Central Government. Whenever there is the need not to go through the set system, Central Government permission is a must.The Dalai Lama also did his best to seek authorization of the Central Government which would therefore issue him certificate of authority and seal of power.All these were recorded in archives, part of which are contained in the book. Its major chapters contain 154 pieces of archives related with certification of the Dalai Lama and the Panchen Erdeni under the reign of Qing Emperor Shunzhi, the demise of the Dalai Lama and the Panchen Erdeni, efforts made to look for their soul boys, selection of th

    In 1952, Mme Yvonne Choquet-Bruhat published a major paper, Théorème d'existence pour certains systèmes d'équations aux dérivées partielles non linéaires (Acta Math. 88 141-225), which laid the foundation for modern studies of the Cauchy problem in general relativity. The fiftieth anniversary of this event was celebrated with an eponymous Cargèse Summer School in 2002. The proceedings of that summer school are summarized electronically (as audio, video, transparencies and lecture notes, where available) on a DVD archive included with this volume, and are also available on the internet. However the organizers decided that a separate volume describing the 'state of the art in mathematical general relativity' would be useful, and this book is the result. It includes some material not covered in the school and excludes some school material which has been covered adequately elsewhere. Unfortunately, I was unable to find, electronically, a table of contents, which every prospective purchaser would wish to see, and so this review does in fact list all the articles, ordered, roughly, by length. About one fifth of the book is devoted to a survey of Smoothness at Null Infinity and the Structure of Initial Data by Helmut Friedrich. This is a modern study of gravitational radiation, and the analysis of Einstein's equations. It is extremely helpful to survey all of this material, including some of the latest developments, using a consistent notation. This article is strongly recommended to anyone hoping to gain a foothold in this area. Note also that 47 pages of transparencies have become 84 book pages. Lars Andersson has surveyed, in The Global Existence Problem in General Relativity, some results and conjectures about the global properties of 3+1-dimensional spacetimes with a compact Cauchy surface. Again it is very useful to have essentially all of the known results presented in a consistent notation. This material is not on the DVD. Yvonne Choquet-Bruhat has

    Koch, Jaco

    2014-01-01

    This project aims to quantify natural gamma radiation in gold tailings disposal facilities (TDFs) relative to uranium concentration data in order to use natural gamma detection methods as alternative methods for uranium resource estimation modelling in gold tailings. Uranium migration within the New Machavie TDF was also investigated as migration affects both the grade of the TDF as a uranium resource and poses a threat to the environment. In order to determine the most appropr...

  14. Department of Energy depleted uranium recycle

    International Nuclear Information System (INIS)

    With its strategic supply of depleted uranium, the Department of Energy is studying reuse of the material in nuclear radiation shields, military hardware, and commercial applications. the study is expected to warrant a more detailed uranium recycle plan which would include consideration of a demonstration program and a program implementation decision. Such a program, if implemented, would become the largest nuclear material recycle program in the history of the Department of Energy. The bulk of the current inventory of depleted uranium is stored in 14-ton cylinders in the form of solid uranium hexafluoride (UF6). The radioactive 235U content has been reduced to a concentration of 0.2% to 0.4%. Present estimates indicate there are about 55,000 UF6-filled cylinders in inventory and planned operations will provide another 2,500 cylinders of depleted uranium each year. The United States government, under the auspices of the Department of Energy, considers the depleted uranium a highly-refined strategic resource of significant value. A possible utilization of a large portion of the depleted uranium inventory is as radiation shielding for spent reactor fuels and high-level radioactive waste. To this end, the Department of Energy study to-date has included a preliminary technical review to ascertain DOE chemical forms useful for commercial products. The presentation summarized the information including preliminary cost estimates. The status of commercial uranium processing is discussed. With a shrinking market, the number of chemical conversion and fabrication plants is reduced; however, the commercial capability does exist for chemical conversion of the UF6 to the metal form and for the fabrication of uranium radiation shields and other uranium products. Department of Energy facilities no longer possess a capability for depleted uranium chemical conversion

  15. Foreign uranium supply. Final report

    International Nuclear Information System (INIS)

    This report presents an assessment of the extent to which foreign uranium may be available to United States utilities in the short term (through 1980), the intermediate term (1981--1985), and the long term (1986--95). All free world foreign uranium producers and prospects are included, with particular emphasis on Australia, Canada, southern Africa, France, and French-speaking Africa. The assessment includes reserves, resources, exploration and prospects; firm and potential production capacity and prospects; national policies and relevant political and economic conditions; foreign uranium demand; etc. Conclusions are: Foreign supply capability is greater than foreign demand in the near term. The current availability of uncommitted future Australian production presents an unusual opportunity for establishing commercial relations with very substantial producers. Foreign uranium contracts represent an increase in diversity of supply and access to resources but have less assurance of supply than do domestic contracts. However, uncertainties can frequently be accommodated within an overall procurement program, thereby retaining the diversity and price advantages of foreign procurement. The practice of market pricing of contracts reduces the incentives for foreign contracting

  16. Uranium - a factor limiting nuclear energy?

    International Nuclear Information System (INIS)

    Nuclear power has been back as a topic of public debate since early this year. A special subject under discussion is the extension of nuclear power plant life. Hardly had it been on the agenda, when interested parties announced that this st ep was impossible because uranium reserves were no longer sufficient. A variety of terms are being used in this discussion without their meaning being taken int o account: stocks, resources, and reserves. To clarify the situation, this artic le outlines important aspects of short and long term uranium supplies, and analy zes their meaning. Here are some of the most important issues under consideration: - For what period of time is there really enough uranium? - Is uranium becoming the limiting factor in the use of nuclear power? - Is uranium really a 'sustainable' energy resource? - Will higher prices extend the range? - What is the in fluence of the price of uranium on the cost of electricity generation? Among oth er results, it is found that comprehensive sources of low-price uranium and nucl ear fuels are, or can be made, available worldwide. Consequently, the 'range' is beyond the time frames currently mentioned, also as a function of technological factors, i.e. reaching several hundred years. It is also important to note that nuclear power - ensures greater independence of volatile imported sources, - guarantees reliably low electricity prices, - has a huge potential of environmental protection, and - is a clean source of energy.

  18. Uranium Management - Preservation of a National Asset

    Energy Technology Data Exchange (ETDEWEB)

    Jackson, J. D.; Stroud, J. C.

    2002-02-27

    The Uranium Management Group (UMG) was established at the Department of Energy's (DOE's) Oak Ridge Operations in 1999 as a mechanism to expedite the de-inventory of surplus uranium from the Fernald Environmental Management Project site. This successful initial venture has broadened into providing uranium material de-inventory and consolidation support to the Hanford site as well as retrieving uranium materials that the Department had previously provided to universities under the loan/lease program. As of December 31, 2001, {approx} 4,300 metric tons of uranium (MTU) have been consolidated into a more cost effective interim storage location at the Portsmouth site near Piketon, OH. The UMG continues to uphold its corporate support mission by promoting the Nuclear Materials Stewardship Initiative (NMSI) and the twenty-five (25) action items of the Integrated Nuclear Materials Management Plan (1). Before additional consolidation efforts may commence to remove excess inventory from Environmental Management closure sites and universities, a Programmatic Environmental Assessment (PEA) must be completed. Two (2) noteworthy efforts currently being pursued involve the investigation of re-use opportunities for surplus uranium materials and the recovery of usable uranium from the shutdown Portsmouth cascade. In summary, the UMG is available as a DOE complex-wide technical resource to promote the responsible management of surplus uranium.

  19. Documentation of the Uranium Market Model (UMM)

    International Nuclear Information System (INIS)

    The Uranium Market Model is used to make projections of activity in the US uranium mining and milling industry. The primary data sources were EIA, the Nuclear Assurance Corporation, and, to a lesser extent, Nuexco and Nuclear Resources International. The Uranium Market Model is a microeconomic simulation model in which uranium supplied by the mining and milling industry is provided to meet the demand for uranium by electric utilities with nuclear power plants. Uranium is measured on a U3O8 (uranium oxide) equivalent basis. The model considers every major production center and utility on a worldwide basis (with Centrally Planned Economies considered in a limited way), and makes annual projections for each major uranium production and consumption region in the world. Typically, nine regions are used: the United States, Canada, Australia, South Africa, Other Africa, Europe, Latin America, the Far East, and Other. Production centers and utilities are identified as being in one of these regions. In general, the model can accommodate any user-provided set of regional definitions and data

    All the physics we observe in our world is underlain by special relativity, a theory that has survived for more than a hundred years, in many respects completely intact. Yet despite its status as the most stringently tested theory in all of physics, special relativity is still frequently questioned. In the last decade and a half, many scientists have come to believe that special relativity, as Einstein formulated it, will need to be modified to accommodate a quantum theory of gravity. {\\it Special Relativity: Will it Survive the Next 101 Years?} is a volume intended to introduce the reader to this new and still slightly controversial area of research. The book is divided into four parts. The first part is essentially historical. It consists of an essay discussing Einstein's work in the context of contemporary technological developments and a amusing note by R W P Drever on a precision Lorentz test that he performed literally in his backyard. These set the stage for the more modern material that follows. Part II discusses the theory of relativity and its mathematical foundations, from completely modern perspectives. There is much here that may be new even for experts on special relativity, and a significant level of mathematical sophistication on the part of the reader is assumed. A number of the lectures delve into the crucial question of how special relativity and its generalizations can be combined with quantum mechanics. The third part discusses theoretical models of Lorentz violation, and all the important paradigms that appear in the current literature are considered. These include the standard model extension (an effective field theory), modified dispersion relations and 'double special relativity', and noncommutative geometry. These lectures generally delve into less detail than those in part II; the focus is on helping the reader digest the new principles that must arise in theories without Lorentz symmetry. The final part of the volume covers current

    There is a new tradition in England called Apple Day which is held on some day in October. The actual day varies from place to place. For instance, in 2003, 23 October was Apple Day at Woolsthorpe Manor, the house where Isaac Newton was born and where, during the Plague, he is said to have developed the theory of gravity. (For information on future Apple Days see, for example, http://www.nationaltrust.org.uk/main/thingstodo.) Last year in our garden we picked an apple which weighed one pound, thirteen and a half ounces (1 lb 13 1/2 oz or 29 1/2 oz). The following day we went to an Apple Day event where there were many exotic apples on display, varieties which are not sold in shops. One of the varieties there was called 'Twenty Ounce'. By now you may be wondering what all this has to do with the book being reviewed. We shall return to this later. This entertaining book is ostensibly about units, in particular about Imperial and metric units, but there are numerous informative digressions. The author reminds us that almost every country 'with the exception of the United States, North and South Yemen, Burma and Brunei' has gone metric. He points out that the United States (US) became officially metric in 1893. However, as early as 1866, the US legal definition of the metre was 39.370000 inches. He tells us that after World War II the (US) inch was rounded down (from 25.400051) to 25.4 mm. There is no mention that the Imperial (British) inch was simultaneously rounded up from 25.399956 mm to 25.4 mm. The author frequently digresses, covering such matters as the trisection of angles and Eratosthenes' graphic solution for duplicating the cube. There is an informative discussion on the length of the day: appropriately 25 December, which lasts for 24 h and 30 s, is the longest day. He shows how with cycles and epicycles one can construct an ellipse. Ptolemy did not realize the importance of the focus of the ellipse. The author discusses various topics in the development of

    This book gives a clear exposition of quantum field theory at the graduate level and the contents could be covered in a two semester course or, with some effort, in a one semester course. The book is well organized, and subtle issues are clearly explained. The margin notes are very useful, and the problems given at the end of each chapter are relevant and help the student gain an insight into the subject. The solutions to these problems are given in chapter 12. Care is taken to keep the numerical factors and notation very clear. Chapter 1 gives a clear overview and typical scales in high energy physics. Chapter 2 presents an excellent account of the Lorentz group and its representation. The decomposition of Lorentz tensors under SO(3) and the subsequent spinorial representations are introduced with clarity. After giving the field representation for scalar, Weyl, Dirac, Majorana and vector fields, the Poincaré group is introduced. Representations of 1-particle states using m2 and the Pauli Lubanski vector, although standard, are treated lucidly. Classical field theory is introduced in chapter 3 and a careful treatment of the Noether theorem and the energy momentum tensor are given. After covering real and complex scalar fields, the author impressively introduces the Dirac spinor via the Weyl spinor; Abelian gauge theory is also introduced. Chapter 4 contains the essentials of free field quantization of real and complex scalar fields, Dirac fields and massless Weyl fields. After a brief discussion of the CPT theorem, the quantization of electromagnetic field is carried out both in radiation gauge and Lorentz gauge. The presentation of the Gupta Bleuler method is particularly impressive; the margin notes on pages 85, 100 and 101 invaluable. Chapter 5 considers the essentials of perturbation theory. The derivation of the LSZ reduction formula for scalar field theory is clearly expressed. Feynman rules are obtained for the λphi4 theory in detail and those of QED

  11. Depleted Uranium Management

    International Nuclear Information System (INIS)

    The paper considers radiological and toxic impact of the depleted uranium on the human health. Radiological influence of depleted uranium is less for 60 % than natural uranium due to the decreasing of short-lived isotopes uranium-234 and uranium-235 after enrichment. The formation of radioactive aerosols and their impact on the human are mentioned. Use of the depleted uranium weapons has also a chemical effect on intake due to possible carcinogenic influence on kidney. Uranium-236 in the substance of the depleted uranium is determined. The fact of beta-radiation formation in the uranium-238 decay is regarded. This effect practically is the same for both depleted and natural uranium. Importance of toxicity of depleted uranium, as the heavier chemical substance, has a considerable contribution to the population health. The paper analyzes risks regarding the use of the depleted uranium weapons. There is international opposition against using weapons with depleted uranium. Resolution on effects of the use of armaments and ammunitions containing depleted uranium was five times supported by the United Nations (USA, United Kingdom, France and Israel did not support). The decision for banning of depleted uranium weapons was supported by the European Parliament

  12. Death Valley 10 x 20 NTMS area, California and Nevada. Data report: National Uranium Resource Evaluation program, hydrogeochemical and stream sediment reconnaissance

    International Nuclear Information System (INIS)

    Results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Death Valley 10 x 20 quadrangle are presented. Stream sediment samples were collected from small streams at 649 sites or at a nominal density of one site per 20 square kilometers. Ground water samples were collected at 62 sites or at a nominal density of one site per 220 square kilometers. Neutron activation analysis results are given for uranium and 16 other elements in sediments, and for uranium and 8 other elements in ground water and surface water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Statistical summaries of data and a brief description of results are given. A generalized geologic map and a summary of the geology of the area are included. Key data from ground water sites include (1) water chemistry measurements (pH, conductivity, and alkalinity), (2) scintillometer readings, and (3) elemental analyses (U, Br, Cl, F, He, Mn, Na, and V). Supplementary data include site descriptors, tabulated analytical data for Al, Dy, and Mg, and histograms and cumulative frequency plots for all elements. Key data from stream sediment sites include (1) water quality measurements (2) important elemental analyses, (U, Th, Hf, Ce, Fe, Mn, Sc, Na, Ti, and V), and (3) scintillometer readings. Supplementary data from stream sediment sites include sample site descriptors (stream characteristics, vegetation, etc.), additional elemental analyses (Dy, Eu, La, Lu, Sm, and Yb), and histograms and cumulative frequency plots for all elements

  13. Geological and geochemical aspects of uranium deposits. A selected, annotated bibliography

    International Nuclear Information System (INIS)

    A bibliography of 479 references encompassing the fields of uranium and thorium geochemistry and mineralogy, geology of uranium deposits, uranium mining, and uranium exploration techniques has been compiled by the Ecological Sciences Information Center of Oak Ridge National Laboratory. The bibliography was produced for the National Uranium Resource Evaluation Program, which is funded by the Grand Junction Office of the Department of Energy. The references contained in the bibliography have been divided into the following eight subject categories: (1) geology of deposits, (2) geochemistry, (3) genesis O deposits, (4) exploration, (5) mineralogy, (6) uranium industry, (7) reserves and resources, and (8) geology of potential uranium-bearing areas. All categories specifically refer to uranium and thorium; the last category contains basic geologic information concerning areas which the Grand Junction Office feels are particularly favorable for uranium deposition. The references are indexed by author, geographic location, quadrangle name, geoformational feature, taxonomic name, and keyword

  17. Long-term logistic analysis of FBR introduction strategy: avoiding both uranium and plutonium shortage

    Despite comfortable predictions on short to mid-term uranium resources, there is still a concern about long-term availability of competitive uranium resources. In order to achieve substantial uranium saving, early introduction of Fast Breeder Reactor (FBR) is desirable. But it is also known that rapid introduction of FBR could result in plutonium storage. Will there be enough plutonium on a global scale to sustain fast FBR growth? is there any other way to save uranium resource? This paper concludes that multi-option strategies to achieve flexible long-term strategy to avoid both uranium and plutonium storage are desirable. (authors) 3 refs.
