    Scales are inherent forms of measurement used in daily life, just like Celsius or Fahrenheit scales for temperature and Richter for scale for earthquakes. Jointly developed by the IAEA and OECD/NEA in 1990, the purpose of International Nuclear and Radiological Event Scale (INES) is to help nuclear and radiation safety authorities and the nuclear industry worldwide to rate nuclear and radiological events and to communicate their safety significance to the general public, the media and the technical community. INES was initially used to classify events at nuclear power plants only. It was subsequently extended to rate events associated with the transport, storage and use of radioactive material and radiation sources, from those occurring at nuclear facilities to those associated with industrial use. Since its inception, it has been adopted in 69 countries. Events are classified on the scale at seven levels: Levels 1-3 are called 'incidents' and Levels 4-7 'accidents'. The scale is designed so that the severity of an event is about ten times greater for each increase in level on the scale. Events without safety significance are called 'deviations' and are classified Below Scale/Level 0. INES classifies nuclear and radiological accidents and incidents by considering three areas of impact: People and the Environment; Radiological Barriers and Control; Defence-in-Depth. By now, two nuclear accidents were on the highest level of the scale: Chernobyl and Fukumashi. (authors)

    INES - the International Nuclear Event Scale - has now been successfully communicating nuclear risks to the public for five years. Despite being created as a communication tool, its firm scientific base has given it credibility and is responsible, at least in part, for its success. Further improvements in its use are still being made, while keeping in mind the scale's main communication role and the need to respond rapidly to events. (UK)

    The International Nuclear Event Scale (INES) was introduced in March 1990 jointly by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA). Its primary purpose is to facilitate communication and understanding between the nuclear community, the media and the public on the safety significance of events occurring at nuclear installations. The scale was refined in 1992 in the light of experience gained and extended to be applicable to any event associated with radioactive material and/or radiation, including the transport of radioactive materials.This edition of the INES User's Manual incorporates experience gained from applying the 1992 version of the scale and the document entitled 'Clarification of Issues Raised'. As such, it replaces those earlier publications. It does not amend the technical basis of the INES rating procedure but is expected to facilitate the task of those who are required to rate the safety significance of events using the INES scale. The INES communication network currently receives and disseminates event information to the INES National Officers of 60 Member States on special Event Rating Forms which represent official information on the events, including the rating. The INES communication process has led each participating country to set up an internal network which ensures that all events are promptly communicated and rated whenever they have to be reported outside or inside the country. The IAEA provides training services on the use of INES on request

    Full text: Today, the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (NEA) are celebrating the 20th anniversary of the International Nuclear and Radiological Event Scale (INES). Jointly developed by the IAEA and the NEA in 1990, in the aftermath of the Chernobyl accident, the purpose of INES is to help nuclear and radiation safety authorities and the nuclear industry worldwide to rate nuclear and radiological events and to communicate their safety significance to the general public, the media and the technical community. INES has often been compared to other scales used to measure physical properties such as temperature - the Celsius, Kelvin or Fahrenheit scales - or rate events such as earthquakes - the Richter scale. Like these scales, INES also has a sound technical background and can be easily understood. INES was initially used to classify events at nuclear power plants only. It was subsequently extended to rate events occurring in any nuclear facility and during the transport of radioactive material, thus also covering events related to the overexposure of workers. Since 2008, INES has been extended to any event associated with the transport, storage and use of radioactive material and radiation sources, from those occurring at nuclear facilities to those associated with industrial use. More generally, INES has also become a crucial nuclear communications tool. Since its inception, it has been adopted in 69 countries, and an increasing number of countries have expressed their interest in using INES and have designated INES national officers. Over the years, national nuclear safety authorities have made growing use of INES, while the public and the media have become more familiar with the scale and its significance. This is where the true success of INES stands, having helped to foster transparency and provide a better understanding of nuclear-related events and activities.

    Expanding the scope of its activities to include controlling the safe transport of radioactive materials, the French Nuclear Safety Authority (ASN) has decided to apply the INES scale to transport events, following a wide-ranging debate bringing together experts, industry and the Conseil Superieur de la Surete et de l'Information Nucleaire (Higher Council for Nuclear Safety and Information). International interest in French experience has gradually raised the question of harmonised application of the INES scale to transport events by the competent international authorities. (author)

    This paper aims to frame the event overflow organic solvent rich in uranium, from a decanter of ore beneficiation plant, caused by the fall in the supply of electricity, according to the criteria established by the International Nuclear Event Scale and radiological (INES), facilitating the understanding of the occurrence and communication with the public regarding the radiation safety aspects involved. With the fall of electricity, routine procedures in situations of installation stop were performed, however, due to operational failure, the valve on the transfer line liquor was not closed. Thus, the mixer continued being fed with liquor, that led the consequent leakage of solvent loaded with uranium. It reached the drainage system, and the box of rainwater harvesting of the plant. However, immediately after the detection of the event, corrective actions were initiated and the overflow was contained. Regulatory agencies followed the removal of the solvent and on the results of the analysis of environmental monitoring, found that the event did not provide exposure to workers or any other impact. Therefore, comparing the characteristics of the event and the guidelines proposed by the INES scale, it is concluded that the classification of the event is below scale/level 0, confirming the absence of risk to the local population, workers and the environment

    The International Nuclear and Radiological Event Scale is used for promptly and consistently communicating to the public the safety significance of events associated with sources of radiation. It covers a wide spectrum of practices, including industrial use such as radiography, use of radiation sources in hospitals, activities at nuclear facilities, and the transport of radioactive material. By putting events from all these practices into a proper perspective, use of INES can facilitate a common understanding between the technical community, the media and the public. The scale was developed in 1990 by international experts convened by the IAEA and the OECD Nuclear Energy Agency (OECD/NEA). It originally reflected the experience gained from the use of similar scales in France and Japan as well as consideration of possible scales in several countries. Since then, the IAEA has managed its development in cooperation with the OECD/NEA and with the support of more than 60 designated National Officers who officially represent the INES member States in the biennial technical meeting of INES. Initially the scale was applied to classify events at nuclear power plants, and then was extended and adapted to enable it to be applied to all installations associated with the civil nuclear industry. More recently, it has been extended and adapted further to meet the growing need for communication of the significance of all events associated with the transport, storage and use of radioactive material and radiation sources. This revised manual brings together the guidance for all uses into a single document. Events are classified on the scale at seven levels: Levels 4-7 are termed 'accidents' and Levels 1-3 'incidents'. Events without safety significance are classified as 'Below Scale/Level 0'. Events that have no safety relevance with respect to radiation or nuclear safety are not classified on the scale. For communication of events to the public, a distinct phrase has been

  15. The Use of the International Nuclear and Radiological Event Scale (INES) for Event Communication. Guidelines and Good Practices for Setting up a National Framework on the Effective Use of INES for Event Communication

    International Nuclear Information System (INIS)

    2014-10-01

    The IAEA’s International Nuclear and Radiological Event Scale (INES) was developed in 1990 by international experts convened by the IAEA and the OECD Nuclear Energy Agency with the aim of communicating the safety significance of events at nuclear installations. Since then, INES has been expanded to meet the growing need for communicating the safety significance of events giving rise to radiation risk. At present, INES is used for communicating to the public, in a consistent way, the safety significance of an event associated with sources of radiation, whether or not the event occurs at a facility. INES covers a wide spectrum of practices, including industrial uses such as gammagraphy, the use of sources of radiation in medicine, activities at nuclear power plants and research reactors, activities at spent nuclear fuel and radioactive waste management facilities, and the transport of radioactive material. INES has become a widely used tool for putting the safety significance of radiation events into proper perspective. The number of countries using INES has risen steadily over the past five years. As a result, there is a need to ensure the harmonized application of this scale worldwide. Up to now, international activities regarding INES have focused more on developing guidance on rating events than on the ways of using INES. This publication is the first to provide guidance on establishing or improving a national framework for the effective use of INES during event communication. It has been prepared on the basis of national experience with communicating events that have occurred since the introduction of INES. This publication also includes, in Annex I, lessons learned from the application of INES during and after the accident at the Fukushima Daiichi nuclear power plant, Guidance on the Use of INES in Evolving Severe Accidents

  16. Classification of radiation-hazardous objects by the ecological risk rate, based on the concept of the International Nuclear Event Scale (INES)

    International Nuclear Information System (INIS)

    Vetrov, V.A.

    2003-01-01

    The principal categories of the radiation-hazardous objects (RHO) (nuclear fuel cycle plants (NFC including NPP); ships with nuclear engine units and appropriate service facilities; units related with nuclear weapons (design, manufacture, storage, etc.); contaminated territories in the result nuclear accidents and nuclear facilities tests; civil enterprises using the radioactive sources) with real accident risk from radioactive substances (RS) release into environment are considered. For assessment of the ecological risk rate from RHO the International Nuclear Event Scale implemented by IAEA for NPP use is suggested. By opinion of the specialists the INES criteria could be used for radiation events assessment to other RHO that gives possibility for RHO arrangement by the potential hazard rate for environment in the case of accident. For RHO qualitative classification the main parameters assessment influencing on radioactive release risk (amount (total activity) of radioactive substances; possibility of chain reaction development; strength of technological parameters, etc.) was suggested. On the base of the INES all above-listed RHO kinds in the case of accident could be conditionally separated into three categories: 1. most radiation dangerous objects, on which could be severe and serious radiation accidents (corresponding to 4-7 INES levels); 2. RHO on which there is risk for accidents accompanying with RS release (accidents up to 4 INES level). 3. RHO without practical possibility for event (incidents - not higher 3 INES level). Introduction of suggested classification gives possibility for RHO safety control requirements rationalizing to radiation monitoring purposes for both RHO and the local systems

    The trend in the energy sector in most of the industrialized areas of the world shows rather clearly, that the rate of installation of nuclear plants will be very high and that the largest possible units of nuclear material handling and storage facilities will be built. Various experiments and analyses of measurement methods relevant to safeguards, in typical nuclear facilities like a fuel reprocessing or a fabrication plant, have shown that the associated measurement errors as obtained under normal operating conditions are such that they are mainly dominated by systematic errors and that such systematic errors may lie in the range of percentages of the measured amount so that a material balance in such a plant could not normally be closed with high accuracy. The simplest way of going around the problem would be to increase the frequency of striking a material balance over a given period of time. This could however lead to an anormous increase in the technical and financial burden for the operator of a facility. The present paper analyses this problem in some detail for some facilities and shows that with a properly developed information system in such plants and a combination of containment, surveillance and accountancy measures, safeguards statements for relatively low significant amounts can be made with the attainable range of measurement accuracies

    1996-08-01

    An international symposium on Radiodosimetry and Preventive Measures in the Event of a Nuclear Accident was held in Cracow, Poland, from 26 to 28 May 1994. The symposium was organized by the Polish Society for Nuclear Medicine, and co-sponsored by the IAEA. Over 40 experts from Belarus, Latvia, Lithuania, Germany, Poland, the Russian Federation, Sweden and Switzerland participated. The aim of the Symposium was to review models of iodine kinetics used in the calculation of internal radiation doses to the thyroid after the Chernobyl accident, to discuss internal and external radiation dose to the thyroid in terms or risk of thyroid cancer, and to present data on the incidence rate of thyroid cancer in the selected iodine deficient area in Poland. A part of the symposium was dedicated to the physiological basis of iodine prophylaxis and emergency planning for a nuclear accident. Recommendations of the IAEA on preventive measures in the event of a nuclear accident were also addressed. These proceedings contain the full text of the eight invited papers presented at the symposium. Refs, figs, tabs

    Immediately after the Chernobyl accident most European countries established or enhanced their national radioactivity monitoring and information systems. The large transboundary effect of the radioactive release also triggered the need for bilateral and international agreements on the exchange of radiological information in case of a nuclear accident. Based on the experiences gained from existing bi- and multilateral data exchange the Commission of the European Communities has made provision for and is developing technical systems to exchange information of common interest. Firstly the existing national systems and systems based on bilateral agreements are summarized. The objectives and technical realizations of the EC international information exchange systems ECURIE and EURDEP, are described. The experiences gained over the past few years and the concepts for the future, in which central and eastern European countries will be included, are discussed. The benefits that would result from improving the international exchange of radiological information in the event of a future nuclear accident are further being described

    1993-01-01

    This volume presents the results of the starter event analysis and the event tree analysis for the Unit 1 of the Laguna Verde nuclear power station. The starter event analysis includes the identification of all those internal events which cause a disturbance to the normal operation of the power station and require mitigation. Those called external events stay beyond the reach of this study. For the analysis of the Laguna Verde power station eight transient categories were identified, three categories of loss of coolant accidents (LOCA) inside the container, a LOCA out of the primary container, as well as the vessel break. The event trees analysis involves the development of the possible accident sequences for each category of starter events. Events trees by systems for the different types of LOCA and for all the transients were constructed. It was constructed the event tree for the total loss of alternating current, which represents an extension of the event tree for the loss of external power transient. Also the event tree by systems for the anticipated transients without scram was developed (ATWS). The events trees for the accident sequences includes the sequences evaluation with vulnerable nucleus, that is to say those sequences in which it is had an adequate cooling of nucleus but the remoting systems of residual heat had failed. In order to model adequately the previous, headings were added to the event tree for developing the sequences until the point where be solved the nucleus state. This process includes: the determination of the failure pressure of the primary container, the evaluation of the environment generated in the reactor building as result of the container failure or cracked of itself, the determination of the localization of the components in the reactor building and the construction of boolean expressions to estimate the failure of the subordinated components to an severe environment.

    The Level 1 results of Laguna Verde Nuclear Power Plant PRA are presented in the I nternal Event Analysis of Laguna Verde Unit 1 Nuclear Power Plant , CNSNS-TR-004, in five volumes. The reports are organized as follows: CNSNS-TR-004 Volume 1: Introduction and Methodology. CNSNS-TR-004 Volume 2: Initiating Event and Accident Sequences. CNSNS-TR-004 Volume 3: System Analysis. CNSNS-TR-004 Volume 4: Accident Sequence Quantification and Results. CNSNS-TR-004 Volume 5: Appendices A, B and C. This volume presents the results of the system analysis for the Laguna Verde Unit 1 Nuclear Power Plant. The system analysis involved the development of logical models for all the systems included in the accident sequence event tree headings, and for all the support systems required to operate the front line systems. For the Internal Event analysis for Laguna Verde, 16 front line systems and 5 support systems were included. Detailed fault trees were developed for most of the important systems. Simplified fault trees focusing on major faults were constructed for those systems that can be adequately represent,ed using this kind of modeling. For those systems where fault tree models were not constructed, actual data were used to represent the dominant failures of the systems. The main failures included in the fault trees are hardware failures, test and maintenance unavailabilities, common cause failures, and human errors. The SETS and TEMAC codes were used to perform the qualitative and quantitative fault tree analyses. (Author)

Finally, the main results and conclusions for the Internal Event Analysis for Laguna Verde Nuclear Power Plant are presented. The total core damage frequency calculated is 9.03x 10-5 per year for internal events. The most dominant accident sequences found are the transients involving the loss of offsite power, the station blackout accidents, and the anticipated transients without SCRAM (ATWS). (Author)

  7. Nuclear scales

    International Nuclear Information System (INIS)

    Friar, J.L.

    1998-01-01

    Nuclear scales are discussed from the nuclear physics viewpoint. The conventional nuclear potential is characterized as a black box that interpolates nucleon-nucleon (NN) data, while being constrained by the best possible theoretical input. The latter consists of the longer-range parts of the NN force (e.g., OPEP, TPEP, the π-γ force), which can be calculated using chiral perturbation theory and gauged using modern phase-shift analyses. The shorter-range parts of the force are effectively parameterized by moments of the interaction that are independent of the details of the force model, in analogy to chiral perturbation theory. Results of GFMC calculations in light nuclei are interpreted in terms of fundamental scales, which are in good agreement with expectations from chiral effective field theories. Problems with spin-orbit-type observables are noted

    Criteria for taking particular protective actions with the aim of preventing or reducing radiation exposures to the population or to workers in the event of a nuclear accident or radiological emergency can be established on the basis of radiological protection principles for intervention situations. It is of utmost importance that pre-established intervention levels for different protective measures form an integral part of an emergency response plan. Generic optimized intervention levels and their derived operational quantities based on the principles given in this paper are judged to provide protection that would be justified and reasonable optimized for a wide range of accident situations although they can only be used as guidelines. Any specific optimization would lead to intervention levels that might be either higher or lower than those emerging from a generic optimization. (author). 9 refs

  10. Review of the Shoreham Nuclear Power Station Probabilistic Risk Assessment: internal events and core damage frequency

    1985-11-01

    A review of the Probabilistic Risk Assessment of the Shoreham Nuclear Power Station was conducted with the broad objective of evaluating its risks in relation to those identified in the Reactor Safety Study (WASH-1400). The scope of the review was limited to the ''front end'' part, i.e., to the evaluation of the frequencies of states in which core damage may occur. Furthermore, the review considered only internally generated accidents, consistent with the scope of the PRA. The review included an assessment of the assumptions and methods used in the Shoreham study. It also encompassed a reevaluation of the main results within the scope and general methodological framework of the Shoreham PRA, including both qualitative and quantitative analyses of accident initiators, data bases, and accident sequences which result in initiation of core damage. Specific comparisons are given between the Shoreham study, the results of the present review, and the WASH-1400 BWR, for the core damage frequency. The effect of modeling uncertainties was considered by a limited sensitivity study so as to show how the results would change if other assumptions were made. This review provides an independently assessed point value estimate of core damage frequency and describes the major contributors, by frontline systems and by accident sequences. 17 figs., 81 tabs

    1985-01-01

    History can be a very dull subject if it relates to events which have long since lost their relevance. The factors which led to the creation of the International Atomic Energy Agency (IAEA), however, are as important and relevant today as they were when the Agency was first created. Without understanding these factors it is impossible to realise how important the Agency is in the present world or to understand some of the controversies surrounding its future. Central to these controversies is the question of how best to promote the international transfer of nuclear technology without contributing further to the problem of proliferating nuclear explosives or explosive capabilities. One effective means is to subject nuclear materials (see accompanying article in box), which forms the basic link between the manufacture of nuclear explosives and nuclear power generation, to international safeguards. This was realized very early in the development of nuclear power and was given greater emphasis following the deployment of the first two atomic bombs towards the end of World War II. (author)

  12. Learning from nuclear regulatory self-assessment. International peer review of the CSN report on lessons learnt from the essential service water system degradation event at the Vandellos nuclear power plant

    International Nuclear Information System (INIS)

    2006-01-01

    Nuclear regulatory self-assessment together with the benchmarking of regulatory practices against those of other countries operating nuclear power plants are key elements in maintaining a high level of nuclear safety. In that light, the Spanish Consejo de Seguridad Nuclear (CSN) formally asked the OECD Nuclear Energy Agency (NEA) to establish an international peer review team to assess the CSN report on the lessons learnt as a result of the 2004 Vandellos II event involving essential service water system degradation. The International Review Team considers the CSN report prepared in follow-up to the Vandellos event to be a commendable effort in regulatory self-assessment. The report, complemented by this international peer review, should enable the CSN to take appropriate action to ensure that its regulatory supervision is in line with best international practice.

    Existing scenarios for global energy use project that demand will at least double over the next 50 years. Electricity demand is projected to grow even faster. These scenarios suggest that the use of all available generating options, including nuclear energy, will inevitably be required to meet those demands. If nuclear energy is to play a meaningful role in the global energy supply in the foreseeable future, innovative approaches will be required to address concerns about economic competitiveness, environment, safety, waste management, potential proliferation risks and necessary infrastructure. In the event of a renaissance of nuclear energy, adequate infrastructure development will become crucial for Member States considering the future use of nuclear power. The IAEA should be ready to provide assistance in this area. A special resolution was adopted by the General Conference in September 2005 on 'Strengthening the Agency's Activities Related to Nuclear Science, Technology and Applications: Approaches to Supporting Nuclear Power Infrastructure Development'. Previously, in 2000, taking into account future energy scenarios and the needs of Member States, the IAEA General Conference had adopted a resolution initiating the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO). Based on scenarios for the next fifty years, INPRO identified requirements for different aspects of future nuclear energy systems, such as economics, environment, safety, waste management, proliferation resistance and infrastructure and developed a methodology to assess innovative nuclear systems and fuel cycles. Using this assessment tool, the need for innovations in nuclear technology can be defined, which can be achieved through research, development and demonstration (RD and D). INPRO developed these requirements during its first stage, Phase 1A, which lasted from 2001 to mid-2003. In the second stage, Phase 1B (first part), INPRO organized 14 case studies (8 by

    2012-08-14

    This presentation discusses: (1) Definitions of international nuclear security; (2) What degree of security do we have now; (3) Limitations of a nuclear security strategy focused on national lock-downs of fissile materials and weapons; (4) What do current trends say about the future; and (5) How can nuclear security be strengthened? Nuclear security can be strengthened by: (1) More accurate baseline inventories; (2) Better physical protection, control and accounting; (3) Effective personnel reliability programs; (4) Minimize weapons-usable materials and consolidate to fewer locations; (5) Consider local threat environment when siting facilities; (6) Implement pledges made in the NSS process; and (7) More robust interdiction, emergency response and special operations capabilities. International cooperation is desirable, but not always possible.

  18. Communicating about nuclear events: Some suggestions to improve INES

    International Nuclear Information System (INIS)

    Kermisch, Céline; Labeau, Pierre-Etienne

    2013-01-01

    This paper provides a critical analysis of the International Nuclear and Radiological Event Scale (INES) and its use, both from an epistemic and an ethical perspective. As very few papers have been dedicated to this subject, our critical analysis is mainly based on the INES 2009 User's Manual and on technical information issued by different nuclear agencies. Our critical analysis leads to suggest several elements, which could contribute to the improvement of the INES scale and thereby to a better communication about nuclear events. First, we show that multiple criteria are used to assign an INES rating, which could lead to an insufficient differentiation between events. In order to avoid this issue, we suggest to clarify the criteria that are used to assess the level of the event. Then, we show that level 7 of the INES scale is ill-defined as it does not allow to properly take differences in severity between disasters into account. In this regard, we recommend to use an open scale instead. Moreover, we highlight the fact that INES is able to take into account neither events with long-term evolution nor events involving multiple initiators. In this respect, we suggest providing additional guidelines and reflecting about the data on which to rely, in order to assess an INES level. Furthermore, we reflect on who should be rating a nuclear event and we recommend that, for severe events, an independent and plural agency should be in charge. Finally, we show why INES appears to be insufficient for a global communication, and we suggest to complement the INES rating with additional information in parallel. -- Highlights: •We provide a critical analysis of the INES scale and suggestions to improve it. •The rating criteria should be clarified to allow differentiation between events. •An open scale should be used to differentiate between level-7 accidents. •Additional guidelines should be provided for complex and evolving events. •We provide suggestions to satisfy

  20. The international legal framework for national nuclear legislation

    International Nuclear Information System (INIS)

    Siegmund, M.

    1992-01-01

    To what extent the peaceful utilization of nuclear energy will continue to be accepted by the international public also depends upon whether and how the international regime for the peaceful and safe utilization of nuclear energy can be effectively enforced on a global scale, and upon the stability of this system in the future and its constant adaption to the newest state of the art. Basic elements of international law of relevance to national nuclear legislation are: 1. The non-proliferation system, including the safeguards system within the framework of the IAEA; 2. Regulations that directly concern the safe handling of fissile material, and the safety of installations, products, wastes, transportation etc.; 3. Regulation governing the aversion of immediately threatening hazards and international cooperation in the event of disasters; 4. Regulations governing liability for damages in connection with the peaceful utilization of nuclear energy and responsibility under international law. (orig./HSCH) [de

    Nuclear Regulatory Authority of the Slovak Republic and the Embassy of Japan in the Slovak Republic, under the auspices of the Deputy Prime Minister and Minister of Foreign and European Affairs Mr Lajcak organized International Symposium on Nuclear Safety on 14 and 15 March 2013. The symposium took place almost exactly two years after the occurrence of accidents at the Japanese nuclear power plant Fukushima Daichi. The main mission of the symposium was an attempt to contribute to the improvement of nuclear safety by sharing information and lessons presented by Japanese experts with experts from the region, the International Atomic Energy Agency (IAEA) and the European Commission. The aim of the symposium, unlike many other events organized in connection with the events in Fukushima Daichi NPP, was a summary of the results of stress tests and measures update adopted by the international community, especially within Europe. Panel discussion was included to the program of the symposium for this aim was, mainly focused on the current state of implementation of the National Action Plan of the Slovak Republic, the Czech Republic, Poland, Ukraine and Switzerland and the IAEA Action Plan.

    Shaw, S.M.; Cox, P.H.

    1998-01-01

    Education of nuclear pharmacists exists in many countries around the world. The approach and level of education varies between countries depending upon the expectations of the nuclear pharmacist, the work site and the economic environment. In Australia, training is provided through distance learning. In Europe and Canada, nuclear pharmacists and radiochemists receive postgraduate education in order to engage in the small-scale preparation and quality control of radiopharmaceuticals as well as research and development. In the U.S.A., nuclear pharmacy practitioners obtain basic knowledge primarily through undergraduate programs taken when pursuit the first professional degree in pharmacy. Licensed practitioners in pharmacy enter the practice of nuclear pharmacy through distance learning programs or short courses. While different approaches to education exist, there is a basic core of knowledge and a level of competence required of all nuclear pharmacists and radiochemists providing radiopharmaceutical products and services. It was with this realization that efforts were initiated to develop harmonization concepts and documents pertaining to education in nuclear pharmacy. The benefits of international harmonization in nuclear pharmacy education are numerous. Assurance of the availability of quality professionals to provide optimal products and care to the patient is a principle benefit. Spanning national barriers through the demonstration of self governance and unification in education will enhance the goal of increased freedom of employment between countries. Harmonization endeavors will improve existing education programs through sharing of innovative concepts and knowledge between educators. Documents generated will benefit new educational programs especially in developing nations. A committee on harmonization in nuclear pharmacy education was formed consisting of educators and practitioners from the international community. A working document on education was

  4. International aspects of nuclear accidents

    Uematsu, K.

    1989-09-01

    The accident at Chernobyl revealed that there were shortcomings and gaps in the existing international mechanisms and brought home to governments the need for stronger measures to provide better protection against the risks of severe accidents. The main thrust of international co-operation with regard to nuclear safety issues is aimed at achieving a uniformly high level of safety in nuclear power plants through continuous exchanges of research findings and feedback from reactor operating experience. The second type of problem posed in the event of an accident resulting in radioactive contamination of several countries relates to the obligation to notify details of the circumstances and nature of the accident speedily so that the countries affected can take appropriate protective measures and, if necessary, organize mutual assistance. Giving the public accurate information is also an important aspect of managing an emergency situation arising from a severe accident. Finally, the confusion resulting from the unwarranted variety of protective measures implemented after the Chernobyl accident has highlighted the need for international harmonization of the principles and scientific criteria applicable to the protection of the public in the event of an accident and for a more consistent approach to emergency plans. The international conventions on third party liability in the nuclear energy sector (Paris/Brussels Conventions and the Vienna Convention) provide for compensation for damage caused by nuclear accidents in accordance with the rules and jurisdiction that they lay down. These provisions impose obligations on the operator responsible for an accident, and the State where the nuclear facility is located, towards the victims of damage caused in another country

    An External Event is an event that originates outside the site and whose effects on the Nuclear Power Plants (NPP) should be considered. Such events could be of natural or human induced origin and should be identified and selected for design purposes during the site evaluation process. This work shows that the subtropics and mid latitudes of South America east of the Andes Mountain Range have been recognized as prone to severe convective weather. In Brazil, the events of tornadoes are becoming frequent; however there is no institutionalized procedure for a systematic documentation of severe weather. The information is done only for some scientists and by the newspapers. Like strong wind can affect the structural integrity of buildings or the pressure differential can affect the ventilation system, our concern is the safety of NPP and for this purpose the recommendations of International Atomic Energy Agency, Nuclear Regulatory Commission and Comissao Nacional de Energia Nuclear are showed and also a data base of tornadoes in Brazil is done.

    Cartwright, P.; Rocchio, J.P.

    1978-01-01

    Light water reactors (LWRs), originally developed in the United States, became the nuclear workhorses for utilities in Europe and Japan largely because the U.S. industry was willing and able to transfer its nuclear know-how abroad. In this international effort, the industry had the encouragement and support of the U.S. governement. In the case of the boiling water reactor (BWR) the program for technology transfer was developed in response to overseas customer demands for support in building local designs and manufacturing capabilities. The principal vehicles have been technology exchange agreements through which complete engineering and manufacturing information is furnished covering BWR systems and fuel. Agreements are held with companies in Germany, Japan, Italy, and Sweden. In recent years, a comprehensive program of joint technology development with overseas manufacturers has begun. The rapidly escalating cost of nuclear research and development make it desirable to minimize duplication of effort. These joint programs provide a mechanism for two or more parties jointly to plan a development program, assign work tasks among themselves, and exchange test results. Despite a slower-than-hoped-for start, nuclear power today is playing a significant role in the economic growth of some developing countries, and can continue to do so. Roughly half of the 23 free world nations that have adopted LWRs are developing countries

    Sternat, Matthew R. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

    2015-02-01

    As global nuclear energy expands, assuring peaceful uses of nuclear technology becomes increasingly important. In addition to complying with international nuclear safeguards, a responsible nuclear energy program promotes a corresponding safeguards culture. Establishment of transparent peaceful uses of nuclear technologies starts with cooperative international engagements and safeguards systems. Developing states investing in nuclear energy must assure the international community of their longterm commitment to safeguards, safety, and security (3S) of nuclear materials and technologies. Cultivating a safeguards culture starts in the initial phases of infrastructure planning and must be integrated into the process of developing a responsible nuclear energy program. Sandia National Laboratories supports the implementation of safeguards culture through a variety of activities, including infrastructure development.

    For all the parties involved with safe use of nuclear energy, the opening for signature of the 'Convention on Nuclear Safety' (signed by 60 countries) and the ongoing work to prepare a 'Convention on Radioactive Waste Safety' are particularly important milestones. 'Convention on Nuclear Safety' is the first legal instrument that directly addresses the safety of nuclear power plants worldwide. The two conventions are only one facet of international cooperation to enhance safety. A review of some cooperative efforts of the past decades, and some key provisions of the new safety conventions, presented in this paper, show how international cooperation is increasing nuclear safety worldwide. The safety philosophy and practices involved with legal framework for the safe use of nuclear power will foster a collective international involvement and commitment. It will be a positive step towards increasing public confidence in nuclear power

    1990-01-01

    The purpose of this book, the culmination of one phase of an ongoing international research project on nuclear suppliers and nonproliferation, is to explore the international political and economic dimensions of nuclear trade, especially as they pertain to the behavior of eleven emerging nuclear-supplier states. More specifically, the book sets forth a conceptual framework for analyzing international nuclear trade; details the domestic and external factors that shape the nuclear export policies of Argentina, Brazil, India, Israel, Japan, Pakistan, the People's Republic of China, South Korea, South Africa, Spain and Taiwan; and identifies and assesses alternative strategies for containing the new proliferation risks posed by these emerging suppliers. The book also describes an innovative effort to utilize a computer-based system for tracking international nuclear trade

  1. Nuclear energy and international cooperation

    There is no need to emphasize that nuclear energy cannot be developed without international cooperation at either the industrial or the academic level. In the meanwhile, there have been some marked political, economic and social changes in recent years which are posing constraints to the international cooperation in nuclear energy. The problems and constraints impeding nuclear power programs cannot be overcome by only one nation; international cooperation with common efforts to solve the problems is essential. Nuclear energy is different from fossil energy resources in that it is highly technology-intensive while others are resource-intensive. International cooperation in technology has an entirely different importance in the field of nuclear energy. Educational institutions will play a role in a new era of the international cooperation.

    Some of the constraints on the nuclear fuel cycle are ones arising from economic and financial reasons, those caused by uranium resources and their distribution, those arising from technical reasons, issues of public acceptance, and those quite independent of normal industrial considerations, but caused by elements of international politics. The nuclear fuel cycle and the international market, matters of nuclear non-proliferation, and international cooperation are discussed

How can we get a maximum output from a maximum number of nuclear plants to reduce the health and the environment damage that we get from fossil fired power plants. How can we reduce the strain on future generations because of the atmospheric pollution and reduce the strain on future generations because we use up all the oil and the gas that we should leave to them for worthier purposes than energy production.

    Even though not all the world's nations have developed a nuclear power industry, nuclear safety is unquestionably an international issue. Perhaps the most compelling proof is the 1986 accident at Chornobyl nuclear power plant in what is now Ukraine. The U.S. Department of Energy conducts a comprehensive, cooperative effort to reduce risks at Soviet-designed nuclear power plants. In the host countries : Armenia, Ukraine, Russia, Bulgaria, the Czech Republic, Hungary, Lithuania, Slovakia, and Kazakhstan joint projects are correcting major safety deficiencies and establishing nuclear safety infrastructures that will be self-sustaining.The U.S. effort has six primary goals: 1. Operational Safety - Implement the basic elements of operational safety consistent with internationally accepted practices. 2. Training - Improve operator training to internationally accepted standards. 3. Safety Maintenance - Help establish technically effective maintenance programs that can ensure the reliability of safety-related equipment. 4. Safety Systems - Implement safety system improvements consistent with remaining plant lifetimes. 5. Safety Evaluations - Transfer the capability to conduct in-depth plant safety evaluations using internationally accepted methods. 6. Legal and Regulatory Capabilities - Facilitate host-country implementation of necessary laws and regulatory policies consistent with their international treaty obligations governing the safe use of nuclear power

    In this paper author deals with the concept of establishing the International Nuclear University (INU) would be one of the most viable options. The INU would provide young professionals with not only university-level education but also high-skill training in the fields of nuclear technology. The program will emphasize on global and multi- disciplinary perspectives, which should offer our young generation broader opportunities of advanced education and motivate professional staffs in the enhancement of their knowledge and skills. The 'World Council of Nuclear Education' could be formed to steer the INU for close international cooperation under the auspices of the IAEA. The INU would organize a world network of existing nuclear- related educational organizations and training centers which already exist in Member States. Existing facilities and can be utilized at maximum. Use of cyber-lecturing through Internet, cross-approval of credits among educational organizations in degree work, certification of credits by the authorized body like IAEA, human resources placement services, etc. are some of the activities that the INU could provide in addition to its professional training and higher education.

After the Tech Demo, a series of cooperation projects on nuclear safeguards and security were developed. To support the security of 2008 Beijing Summer Olympic Games, China Atomic Energy Authority (CAEA), worked with IAEA and the U.S. Department of Energy/National Nuclear Security Administration (DOE/NNSA), carried out trainings for the officials from public security, border control and customs, etc. for strengthening the response capabilities to the Major Public Events (MPEs) and implemented physical security upgrades and radioactive sources recovery at facilities near Olympic venues. As a partner state of the Global Initiative to Combat Nuclear Terrorism, China organized a scenario-based workshop on radioactive detection and emergency response in cooperation with U.S. in December 2007, more than 60 Participants from 20 more countries participated the workshop. To strengthen the training capability on nuclear safeguards and security, CAEA and the IAEA jointly established a 'CAEA-IAEA Joint Training Center on Nuclear Safeguards and Security' in December 2006, located at China Institute of Atomic Energy (CIAE). International Cooperation is a very important element in developing global nuclear security regime.

    The historical perspectives of the international organizations' role concerning the development and spreading of the peaceful uses of nuclear energy, taking into account the national interests within and towards these organizations, are portrayed. The difference in political status between the so-called nuclear and non-nuclear States, lodged in Articles I and II of the Non-Proliferation Treaty is an important factor. The effects so far of these differences in status on the interest of nuclear States to participate in organizations and on factors which might possibly lead to conflict between these two groups are presented.

    This volume presents the results of the starter event analysis and the event tree analysis for the Unit 1 of the Laguna Verde nuclear power station. The starter event analysis includes the identification of all those internal events which cause a disturbance to the normal operation of the power station and require mitigation. Those called external events stay beyond the reach of this study. For the analysis of the Laguna Verde power station eight transient categories were identified, three categories of loss of coolant accidents (LOCA) inside the container, a LOCA out of the primary container, as well as the vessel break. The event trees analysis involves the development of the possible accident sequences for each category of starter events. Events trees by systems for the different types of LOCA and for all the transients were constructed. It was constructed the event tree for the total loss of alternating current, which represents an extension of the event tree for the loss of external power transient. Also the event tree by systems for the anticipated transients without scram was developed (ATWS). The events trees for the accident sequences includes the sequences evaluation with vulnerable nucleus, that is to say those sequences in which it is had an adequate cooling of nucleus but the remoting systems of residual heat had failed. In order to model adequately the previous, headings were added to the event tree for developing the sequences until the point where be solved the nucleus state. This process includes: the determination of the failure pressure of the primary container, the evaluation of the environment generated in the reactor building as result of the container failure or cracked of itself, the determination of the localization of the components in the reactor building and the construction of boolean expressions to estimate the failure of the subordinated components to an severe environment.

    1992-01-01

    Japan is not a contracting party of any international convention in the field of nuclear civil liability, and neither are other east Asian countries who have or will soon have nuclear plants. Therefore, the ordinary rules on private international law will play an important role in dealing with transfrontier nuclear civil liability. Above all, the problems on judicial jurisdiction and governing law are crucial points. With regard to the relations between the above countries and the countries whose legal systems are within the framework of Paris or Vienna Conventions, geographical scopes of these conventions are to be considered. There are two different parts in the international civil liability conventions: uniform civil liability law and mutual funds. As to the first, it is important that, even without the conventions, the basic structure of the nuclear civil liability laws in non-member countries are almost the same with those of members. In any event, considering that the establishment of a single international regime to cover all countries will be hardly possible, legal consequences under the private international law will be explored.

    The Fukushima Daiichi nuclear accident was the worst at a nuclear facility since the Chernobyl accident in 1986. It caused deep public anxiety and damaged confidence in nuclear power. Following this accident, strengthening nuclear safety standards and emergency response has become an imperative at the global level. The IAEA is leading in developing a global approach, and the IAEA Action Plan on Nuclear Safety is providing a comprehensive framework and acting as a significant driving force to identify lessons learned and to implement safety improvements. Strengthening nuclear safety is addressed through a number of measures proposed in the Action Plan including 12 main actions focusing on safety assessments in the light of the accident. Significant progress has been made in assessing safety vulnerabilities of nuclear power plants, strengthening the IAEA's peer review services, improvements in emergency preparedness and response capabilities, strengthening and maintaining capacity building, as well as widening the scope and enhancing communication and information sharing with Member States, international organizations and the public. Progress has also been made in reviewing the IAEA's safety standards, which continue to be widely applied by regulators, operators and the nuclear industry in general, with increased attention and focus on accident prevention, in particular severe accidents, and emergency preparedness and response.

    Full Text Available The loss of off-site power (LOOP event occurs when all electrical power to the nuclear power plant from the power grid is lost. Complete failure of both off-site and on-site alternating current (AC power sources is referred to as a station blackout (SBO. Combined LOOP and SBO events are analyzed in this paper. The analysis is done for different time delays between the LOOP and SBO events. Deterministic safety analysis is utilized for the assessment of the plant parameters for different time delays of the SBO event. Obtained plant parameters are used for the assessment of the probabilities of the functional events in the SBO event tree. The results show that the time delay of the SBO after the LOOP leads to a decrease of the core damage frequency (CDF from the SBO event tree. The reduction of the CDF depends on the time delay of the SBO after the LOOP event. The results show the importance of the safety systems to operate after the plant shutdown when the decay heat is large. Small changes of the basic events importance measures are identified with the introduction of the delay of the SBO event.

    The satellite detection of a nuclear explosion in the South Atlantic and Israel's destruction of a research reactor in Iraq make it essential to strengthen existing monitoring and enforcement programs to prevent proliferation. While there was no reliable evidence that either South Africa or Iraq was violating non-proliferation agreements, worst case scenarios can demonstrate to unfriendly countries that South Africa had diverted fuel to test a nuclear weapon and that Iraq is intending to produce weapons-grade plutonium 239. The situation can be improved by formulating better terms and conditions for internationalizing access to materials. Nuclear suppliers need to agree on terms that will assure their customers that contracts for civil programs will be honored. The International Atomic Energy Agency (IAEA), which includes both nuclear suppliers and customers, could achieve stronger agreements that take into account recent technological advances that will expand enrichment and reprocessing activities. 23 references, 1 figure

    to identify trends that might pass unnoticed. There are several methodologies for evaluation of operational events, specifically, for the determination of the causes of the event, where the concepts of root cause, direct cause and causal factors, among others. However, the most recent methodology in use in Brazil, date of 2003. The subject is so important that there is national legislation dealing with the theme, also it need of update. The actual regulations establishes criteria for notification of the occurrence of events considered significant for safety and establishes criteria and deadlines for the issuance of the report. Is also discussed the relationship between occurrence of operational events and a potential application for the life extension of the nuclear power plants, considering the regulatory focus, theme quite present in the international field. The present study intends to present a modern, appropriate methodology for evaluation of operational events, focusing on regulatory aspects and verify its applicability to nuclear power plants. Will also be presented a study of the occurrence of events, focusing on the last five years of operation. Finally will be also presented to international trends in development on this area. (author)

This volume presents the results of the system analysis for the Laguna Verde Unit 1 Nuclear Power Plant. The system analysis involved the development of logical models for all the systems included in the accident sequence event tree headings, and for all the support systems required to operate the front line systems. For the Internal Event analysis for Laguna Verde, 16 front line systems and 5 support systems were included. Detailed fault trees were developed for most of the important systems. Simplified fault trees focusing on major faults were constructed for those systems that can be adequately represent,ed using this kind of modeling. For those systems where fault tree models were not constructed, actual data were used to represent the dominant failures of the systems. The main failures included in the fault trees are hardware failures, test and maintenance unavailabilities, common cause failures, and human errors. The SETS and TEMAC codes were used to perform the qualitative and quantitative fault tree analyses. (Author)

    Initiating event is defined as any event either internal or external to the nuclear power plants (NPPs) that perturbs the steady state operation of the plant, if operating, thereby initiating an abnormal event such as transient or loss of coolant accident (LOCA) within the NPPs. These initiating events trigger sequences of events that challenge plant control and safety systems whose failure could potentially lead to core damage or large early release. Selection for initiating events consists of two steps i.e. first step, definition of possible events, such as by evaluating a comprehensive engineering, and by constructing a top level logic model. Then the second step, grouping of identified initiating event's by the safety function to be performed or combinations of systems responses. Therefore, the purpose of this paper is to discuss initiating events identification in event tree development process and to reviews other probabilistic safety assessments (PSA). The identification of initiating events also involves the past operating experience, review of other PSA, failure mode and effect analysis (FMEA), feedback from system modeling, and master logic diagram (special type of fault tree). By using the method of study for the condition of the traditional US PSA categorization in detail, could be obtained the important initiating events that are categorized into LOCA, transients and external events

    Japan is the world's third largest power user. Japan's last remaining nuclear reactor shutdown on Saturday 4 Th of May 2012 leaving the country entirely nuclear free. All of 50 of the nation's operable reactors (not counting for the four crippled reactors at Fukushima) are now offline. Before last year's Fukushima nuclear disaster, the country obtained 30% of its energy from nuclear plants, and had planned to produce up to 50% of its power from nuclear sources by 2030. Japan declared states of emergency for five nuclear reactors at two power plants after the units lost cooling ability in the aftermath of Friday 11 March 2011 powerful earthquake. Thousands of (14000) residents were immediately evacuated as workers struggled to get the reactors under control to prevent meltdowns. On March 11 Th, 2011, Japan experienced a sever earthquake resulting in the shutdown of multiple reactors. At Fukushima Daiichi site, the earthquake caused the loss of normal Ac power. In addition it appeals that the ensuing tsunami caused the loss of emergency Ac power at the site. Subsequent events caused damage to fuel and radiological releases offsite. The spent fuel problem is a wild card in the potentially catastrophic failure of Fukushima power plant. Since the Friday's 9.0 earthquake, the plant has been wracked by repeated explosions in three different reactors. Nuclear experts emphasized there are significant differences between the unfolding nuclear crisis at Fukushima and the events leading up to the Chernobyl disaster in 1986. The Chernobyl reactor exploded during a power surge while it was in operation and released a major cloud of radiation because the reactor had no containment structure around to. At Fukushima, each reactor has shutdown and is inside a 20 cm-thick steel pressure vessel that is designed to contain a meltdown. The pressure vessels themselves are surrounded by steel-lined, reinforced concrete shells. Chernobyl disaster was classified 7 on the International

    Stars that get too close to a supermassive black hole are in danger of being tidally disrupted. Stellar two-body relaxation is commonly assumed to be the main driver of these events. Recent work has shown, however, that secular gravitational torques from eccentric nuclear disks can push stars to extreme eccentricities at much higher rates than predicted by two-body relaxation. This work did not include the effects of general relativity, however, which could quench secular torques via rapid apsidal precession. Here we show that, for a star in danger of disruption, general relativity acts on a timescale of less than an orbital period. This short timescale means that general relativity does not have enough time to have a major effect on the orbit. When driven by secular torques from eccentric nuclear disks, tidal disruption event rates are not affected by general relativity.

  12. Keynote address: International nuclear cooperation

    These meetings provide an important opportunity for the nuclear community to assess the scope and direction of its wide-ranging activities. Nuclear technology has given us the tools to understand and shape our physical environment in ways which can solve ancient problems of health, food supply, energy, and many others which affect the quality of our lives. International cooperation is necessary to secure the peaceful benefits of nuclear technology. Meeting global energy needs must be high on any priority list of issues for the coming decade and the 21st century. The satisfaction of energy needs is today and will increasingly be a crucial factor in international stability. Hand in hand with the need to assure energy sufficiency is the need to assure the long-term protection of the environment. Three key elements that give a useful framework for approaching the future of nuclear cooperation are technological factors, economic issues, and political acceptability. Technological avenues to greater safety must be vigorously pursued. Economic alternatives must be identified and objectively weighed. Most important of all, the framework of public confidence must be strengthened

    First responders to chemical, biological, radiological, or nuclear (CBRN) events face decisions having significant human consequences. Some operational decisions are supported by standard operating procedures, yet these may not suffice for ethical decisions. Responders will be forced to weigh their options, factoring-in contextual peculiarities; they will require guidance on how they can approach novel (indeed unique) ethical problems: they need strategies for "on the spot" ethical decision making. The primary aim of this paper is to examine how first responders should approach on the spot ethical decision-making amid the stress and uncertainty of a CBRN event. Drawing on the long-term professional CBRN experience of one of the authors, this paper sets out a series of practical ethical dilemmas potentially arising in the context of a large-scale chemical incident. We propose a broadly consequentialist approach to on the spot ethical decision-making, but one which incorporates ethical values and rights as "side-constraints".

  15. CERN hosts training event on international management

    CERN Multimedia

    2007-01-01

    CERN held its first training event on international management at the Globe on 2 October, sharing its expertise with high-level Swiss managers as part of their year-long part-time executive training programme on advanced management. CERN is often talked about in terms of impressive statistics: the coldest place in the universe, the largest accelerator, the greatest volume of data. Whilst the science is undeniably remarkable, it is backed by a management infrastructure that has to be as cutting-edge as the research it supports. On 2 October, the Learning and Development section of HR organised an event for 60 delegates to come to CERN to learn about international management from those who have taken on the management challenges at the heart of this unique institution. It was the first time that CERN had prepared such an event. SKU, a non-profit organisation, approached our management training team to arrange the event as part of a wee...

  16. International collaboration for nuclear competence building

    2004-01-01

    The life cycle of the nuclear industry is no different to that of any other industry, indeed to most forms of human activity: birth, growth, maturity, decline, rebirth and renewal or death. As a result of the twin facets of long time scales and essential technical competence the industry now faces two problems: how to retain existing skills and competences for the 50 plus years that a plant is operating and how to develop and retain new skills and competences in the areas of decommissioning and radioactive waste management. Different countries are at different stages of the nuclear technology life cycle, a competence that may have declined or be lost in one country may be strong in another. And therein lies one solution to the problems the sector faces - international collaboration. The initiatives such as the NEA Halden project and the Generation IV International Forum lay a ground for quiet optimism that collaboration, information exchange and exchange of personnel continue to be an integral part of the development of nuclear power. Also there is evidence that myriad initiatives are underway in the area of nuclear education and training. Though, national surveys show that still more engineers and scientists having nuclear knowledge are required than are graduating. (author)

    Work for design, research and development is expected to start in 1988 for a new nuclear fusion reactor called ITER (international thermonuclear experimental reactor), which is to be constructed and operated through cooperation among Japan, U.S., Soviet Union and EC. Many talks and discussions concerning the work have been made on various occasions, including the Reagan-Gorbachev talks at Geneva in November 1985, 5th Fusion Working Group meeting in Germany in January 1986, extraordinary FWG meeting at Tokyo in February-March 1986, 11th International Conference on Plasma Physics and Nuclear Fusion Control held under IAEA at Kyoto in November 1986, and first formal four-party (Japan, U.S., Soviet Union, EC) meeting at the IAEA headquarters in March this year. The ITER Technical Working Group was established and its first meeting was held on May 21 - 23, 1987. It was concluded in the meeting that the operation of ITER will be performed in two phases intended for nuclear combustion plasma physics studies and stationary operation, respectively. Major research and development activities carried out in the U.S., Europe, the Soviet Union, Japan and IAEA in connection with the development of ITER are outlined. (Nogami, K.)

  18. Systems for reporting unusual events in nuclear power plants

    International Nuclear Information System (INIS)

    1989-01-01

    Many Member States with nuclear power programmes have established, and are operating, systems for collecting, assessing and disseminating information on safety related events in nuclear power plants. The Agency has recognized the importance of such systems and of achieving compatibility between them. It also recognizes the advantage to be derived from international efforts to exchange operational experience on a worldwide basis. In response to requests put forward during the Special Session of the IAEA General Conference held in September 1986, and to the recommendations made by the International Nuclear Safety Advisory Group (INSAG) to strengthen international co-operation in nuclear safety and the exchange of information on operating experience, the IAEA has been following a two-step approach. Firstly, it continues to assist Member States to establish, improve or harmonize their national systems for collecting, assessing and disseminating safety related operational experience, and secondly, it continues to reinforce the IAEA system for reporting unusual events with safety significance (IAEA Incident Reporting System - IAEA-IRS). Although the prime objective of both activities is to assist regulatory bodies and operating organizations to improve operational safety, operating organizations may also benefit if a similar approach is used to improve equipment reliability and plant availability. The present Guide contains a recommended scheme based on national and international practice applicable to the management of safety related operational experience in nuclear power plants. The user will have to adapt this guidance for specific national conditions and practices. It is important to realize however that for an effective exchange of information through the IAEA-IRS it is a prerequisite to follow the procedures given in the relevant part of this Guide

    2015-10-15

    The term, 'Nuclear Security' became more familiar to Korean public after the government hosted 2012 Seoul Nuclear Security Summit. Nuclear Security is prevention of, detection of and response to criminal or intentional unauthorized acts involving or directed at nuclear material, other radioactive material, associated facilities, or associated activities. Nuclear Security includes physical protection, security of radioactive sources, nuclear forensics, nuclear smuggling prevention, border monitoring, and cyber security with regard to nuclear and other radiological materials. This abstract will review recent international trends and discuss the nuclear security regime in the Republic of Korea (ROK). The international Nuclear Security Regime has been strengthened. The upcoming Chicago Summit in 2016 and the entry into force of the Amendment of Convention on Physical Protection of Nuclear Materials (CPPNM) will bring major changes in nuclear security. The Republic of Korea hosted the 2012 Seoul Summit and strengthened domestic regime to meet international standards. The ROK has worked hard to contribute to the international security regime and to establish a robust domestic security regime against terrorist threats. Even if the nuclear security regime is robust, Risk-informed Nuclear Security management should be established to meet international standards and to implement effective as well as an efficient nuclear security regime.

  2. Root cause analysis for fire events at nuclear power plants

    International Nuclear Information System (INIS)

    1999-09-01

    Fire hazard has been identified as a major contributor to a plant' operational safety risk. The International nuclear power community (regulators, operators, designers) has been studying and developing tools for defending against this hazed. Considerable advances have been achieved during past two decades in design and regulatory requirements for fire safety, fire protection technology and related analytical techniques. The IAEA endeavours to provide assistance to Member States in improving fire safety in nuclear power plants. A task was launched by IAEA in 1993 with the purpose to develop guidelines and good practices, to promote advanced fire safety assessment techniques, to exchange state of the art information, and to provide engineering safety advisory services and training in the implementation of internationally accepted practices. This TECDOC addresses a systematic assessment of fire events using the root cause analysis methodology, which is recognized as an important element of fire safety assessment

  3. Internal dose assessment for environmental monitoring in nuclear power plant accidents

    2013-01-01

    Full Text Available A method for exploiting human's internal contamination data for radioactive release estimation in nuclear power plant accidents is proposed. Nevertheless, such data is often very rough and uncertain; it is accessible even in toughest situations when most of the active and passive monitors are damaged by the accident. These data can be used in combination with other collectable data for estimating the event scale in severe nuclear power plan accidents. The rationale behind the method is that nuclear power plant accidents are often associated with internal contamination of radiation workers involved in the early stages of emergency response activities mainly due to the release of 131I in atmosphere. The proposed inverse analytical approach uses the 131I intake of contaminated workers, their working conditions, chronology of events, and applied personal safety measures during the first hours or days of the emergency response activities to estimate the magnitude of 131I concentration in the air.

    reviews could be a tool to monitor the effectiveness of operating experience activities. A strategy document for the operating experience feedback process, firm procedures for the initial assessment of new events and the carrying-out of data analyses would also be quite useful. The results and suggestions were further examined and their possible utilisation at STUK and the utility organisations was considered. STUK incorporated the knowledge of behavioural sciences for focusing on human performance deficiencies and organisational problems in operational events. STUK intensified the utilisation of its event database (TAPREK) focusing especially on recurring events. In 2000 the recurrence of events, recorded in TAPREK and all reported events during 1995 - 2000, was reviewed using similar causes and consequences of events as screening criteria. The recommendations of the study were taken into account in the latest event investigations of STUK. Due to an increased number of non-compliance with Technical Specifications in 1999 STUK assigned an internal investigation team to assess the reasons for the observed increase and to find generic factors as well as to review the event assessments carried out by the utilities from a human factors point of view. Another investigation team in 2000 was assigned to clarify the causes of the delays related to a safety significant modification project at Loviisa nuclear power plant. At the moment STUK has launched an investigation team to assess procedures and decision making in connection of a temporary software modification, which was made at full power in a turbine protection system at Olkiluoto nuclear power plant.

    The responsibility for nuclear security rests entirely with each State. There is no single international instrument that addresses nuclear security in a comprehensive manner. The legal foundation for nuclear security comprises international instruments and recognized principles that are implemented by national authorities. Security systems at the national level will contribute to a strengthened and more universal system of nuclear security at the international level. The binding security treaties are; Convention on the Physical Protection of Nuclear Material, the 2005 amendment thereto, Safeguards Agreements between the Agency and states required in Connection with the Treaty on the Non-Proliferation of Nuclear Weapons. Model Protocol additional to agreement(s) between State(s) and the Agency for the application of Safeguards Convention on Early Notification of a Nuclear Accident, Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency, Convention on Nuclear Safety, Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management

  7. Advanced nuclear plant design options to cope with external events

    International Nuclear Information System (INIS)

    2006-02-01

    With the stagnation period of nuclear power apparently coming to an end, there is a renewed interest in many Member States in the development and application of nuclear power plants (NPPs) with advanced reactors. Decisions on the construction of several NPPs with evolutionary light water reactors have been made (e.g. EPR Finland for Finland and France) and more are under consideration. There is a noticeable progress in the development and demonstration of innovative high temperature gas cooled reactors, for example, in China, South Africa and Japan. The Generation IV International Forum has defined the International Near Term Deployment programme and, for a more distant perspective, six innovative nuclear energy systems have been selected and certain R and D started by several participating countries. National efforts on design and technology development for NPPs with advanced reactors, both evolutionary and innovative, are ongoing in many Member States. Advanced NPPs have an opportunity to be built at many sites around the world, with very broad siting conditions. There are special concerns that safety of these advanced reactors may be challenged by external events following new scenarios and failure modes, different from those well known for the currently operated reactors. Therefore, the engineering community identified the need to assess the proposed design configurations in relation to external scenarios at the earliest stages of the design development. It appears that an early design optimization in relation to external events is a necessary requirement to achieve safe and economical advanced nuclear power plants. Reflecting on these developments, the IAEA has planned the preparation of a report to define design options for protection from external event impacts in NPPs with evolutionary and innovative reactors. The objective of this publication is to present the state-of-the-art in design approaches for the protection of NPPs with evolutionary and innovative

    1992-01-01

    The paper reviews the activities of the major international organisations in the field of nuclear safety standards; the International Atomic Energy Agency (IAEA), the OECD's Nuclear Energy Agency (NEA) and the Commission of the European Communities. Each organisation encourages the concept of international nuclear safety standards. After Chernobyl, there were calls for some form of binding international nuclear safety standards. Many Member States of IAEA accepted these Codes as a suitable basis for formulating their national safety standards, but the prevailing view was that voluntary compliance with the Codes was the preferred path. With few reactor vendors in a limited international market, the time may be approaching when an internationally licensable nuclear reactor is needed. Commonly accepted safety standards would be a prerequisite. The paper discusses the issues involved and the complexities of standards making in the international arena. (author)

  12. Time scales in tidal disruption events

    Directory of Open Access Journals (Sweden)

    Krolik J.

    2012-12-01

    Full Text Available We explore the temporal structure of tidal disruption events pointing out the corresponding transitions in the lightcurves of the thermal accretion disk and of the jet emerging from such events. The hydrodynamic time scale of the disrupted star is the minimal time scale of building up the accretion disk and the jet and it sets a limit on the rise time. This suggest that Swift J1644+57, that shows several flares with a rise time as short as a few hundred seconds could not have arisen from a tidal disruption of a main sequence star whose hydrodynamic time is a few hours. The disrupted object must have been a white dwarf. A second important time scale is the Eddington time in which the accretion rate changes form super to sub Eddington. It is possible that such a transition was observed in the light curve of Swift J2058+05. If correct this provides interesting constraints on the parameters of the system.

  16. International nuclear cooperation in Asia

    International Nuclear Information System (INIS)

    Lim, Yong-Kyu

    1987-01-01

    Nuclear power project traditionally involve huge financial investment, highly sophisticated technology, and long lead time. Many countries, particularly developing ones, find it impossible to implement their nuclear power programs without technical cooperation and assistance from advanced countries. In this Asia and Pacific Region, seven countries have commercial nuclear power units in operation and/or under construction. Korea has six nuclear power units in operation, and three under construction. Active nuclear cooperation has been instrumental in implementing her abmitious nuclear power programs successfully. Nuclear cooperation is one of the widely recognized necessities, which is quite often talked about among the countries of the Asia and Pacific Region. But the differences in nuclear maturity and national interests among those in the region seem to be standing against it. Given the constraints, it is not easy to select appropriate areas for cooperation. There is no doubt, however, that they should include the nuclear policy, nuclear safety, radwaste management, radiological protection, and the management of nuclear units. In order to effectively promote nuclear cooperation in the Region, the scope of RCA activities must be expanded to include the nuclear power area. The Regional Nuclear Data Bank, the Regional Training Center and the Nuclear Emergency Response Center, for example, would be the effective tools for cooperation to meet the demands of the countries in the Region. In view of the technological gap between Japan and all others in the region, we cannot speak of a regional nuclear cooperation without heavily counting on Japan, the most advanced nuclear state in the region. For these reasons, Japan is expected to share an increasing portion of her nuclear technology with others. (author)

    An External Event is an event that originates outside the site and whose effects on the Nuclear Power Plants (NPP) should be considered. Such events could be of natural or human induced origin and should be identified and selected for design purposes during the site evaluation process. This work shows that the subtropics and mid latitudes of South America east of the Andes Mountain Range have been recognized as prone to severe convective weather. In Brazil, the events of tornadoes are becoming frequent; however there is no institutionalized procedure for a systematic documentation of severe weather. The information is done only for some scientists and by the newspapers. Like strong wind can affect the structural integrity of buildings or the pressure differential can affect the ventilation system, our concern is the safety of NPP and for this purpose the recommendations of International Atomic Energy Agency, Nuclear Regulatory Commission and Comissao Nacional de Energia Nuclear are showed and also a data base of tornadoes in Brazil is done.

    Full-text: The need for human resource development programmes in nuclear security was underlined at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors Meetings. Successive IAEA Nuclear Security Plans, the most recent of which was agreed by the Board of Governors in September 2009, give high priority to assisting States in establishing educational programmes in nuclear security in order to ensure the sustainability of nuclear security improvements. The current Nuclear Security Plan 1 covering 2010-2013 emphasizes on the importance of considering existing capacities at international, regional and national levels while designing nuclear security academic programmes. In the course of implementing the Plan, the IAEA developed a guide entitled Educational Programme in Nuclear Security (IAEA Nuclear Security Series No. 12) that consists of a model of a MAster of Science (M.Sc.) and a Certificate Programme in Nuclear Security. This guide was aims at assisting universities or other educational institutes to developed academic programmes in nuclear security. Independently, some universities already offered academic programmes covering some areas of nuclear security, while other universities have asked the IAEA to support the implementation of these programmes. In order to better address current and future request for assistance in this area, the IAEA establish a collaboration network-International Nuclear Security Education Network (INSEN), among universities who are providing nuclear security education or who are interested in starting an academic programme/ course(s) in nuclear security. Universiti Kebangsaan Malaysia (UKM) is a first local university became a member of INSEN since the beginning of the establishment. (author)

  6. Multi-Unit Initiating Event Analysis for a Single-Unit Internal Events Level 1 PSA

    The Fukushima nuclear accident in 2011 highlighted the importance of considering the risks from multi-unit accidents at a site. The ASME/ANS probabilistic risk assessment (PRA) standard also includes some requirements related to multi-unit aspects, one of which (IE-B5) is as follows: 'For multi-unit sites with shared systems, DO NOT SUBSUME multi-unit initiating events if they impact mitigation capability [1].' However, the existing single-unit PSA models do not explicitly consider multi-unit initiating events and hence systems shared by multiple units (e.g., alternate AC diesel generator) are fully credited for the single unit and ignores the need for the shared systems by other units at the same site [2]. This paper describes the results of the multi-unit initiating event (IE) analysis performed as a part of the at-power internal events Level 1 probabilistic safety assessment (PSA) for an OPR1000 single unit ('reference unit'). In this study, a multi-unit initiating event analysis for a single-unit PSA was performed, and using the results, dual-unit LOOP initiating event was added to the existing PSA model for the reference unit (OPR1000 type). Event trees were developed for dual-unit LOOP and dual-unit SBO which can be transferred from dual- unit LOOP. Moreover, CCF basic events for 5 diesel generators were modelled. In case of simultaneous SBO occurrences in both units, this study compared two different assumptions on the availability of the AAC D/G. As a result, when dual-unit LOOP initiating event was added to the existing single-unit PSA model, the total CDF increased by 1∼ 2% depending on the probability that the AAC D/G is available to a specific unit in case of simultaneous SBO in both units.

  7. Precursor analyses - The use of deterministic and PSA based methods in the event investigation process at nuclear power plants

    International Nuclear Information System (INIS)

    2004-09-01

    The efficient feedback of operating experience (OE) is a valuable source of information for improving the safety and reliability of nuclear power plants (NPPs). It is therefore essential to collect information on abnormal events from both internal and external sources. Internal operating experience is analysed to obtain a complete understanding of an event and of its safety implications. Corrective or improvement measures may then be developed, prioritized and implemented in the plant if considered appropriate. Information from external events may also be analysed in order to learn lessons from others' experience and prevent similar occurrences at our own plant. The traditional ways of investigating operational events have been predominantly qualitative. In recent years, a PSA-based method called probabilistic precursor event analysis has been developed, used and applied on a significant scale in many places for a number of plants. The method enables a quantitative estimation of the safety significance of operational events to be incorporated. The purpose of this report is to outline a synergistic process that makes more effective use of operating experience event information by combining the insights and knowledge gained from both approaches, traditional deterministic event investigation and PSA-based event analysis. The PSA-based view on operational events and PSA-based event analysis can support the process of operational event analysis at the following stages of the operational event investigation: (1) Initial screening stage. (It introduces an element of quantitative analysis into the selection process. Quantitative analysis of the safety significance of nuclear plant events can be a very useful measure when it comes to selecting internal and external operating experience information for its relevance.) (2) In-depth analysis. (PSA based event evaluation provides a quantitative measure for judging the significance of operational events, contributors to

    The study describes and analyzes the structures, the procedures and decision making processes of the International Nuclear Fuel Cycle Evaluation (INFCE). INFCE was agreed by the Organizing Conference to be a technical and analytical study and not a negotiation. The results were to be transmitted to governments for their consideration in developing their nuclear energy policies and in international discussions concerning nuclear energy cooperation and related controls and safeguards. Thus INFCE provided a unique example for decision making by consensus in the nuclear world. It was carried through under mutual respect for each country's choices and decisions, without jeopardizing their respective fuel cycle policies or international co-operation agreements and contracts for the peaceful use of nuclear energy, provided that agreed safeguards are applied.

    2007-03-01

    Computer codes are being used to analyse operational events in nuclear power plants but until now no special attention has been given to the dissemination of the benefits from these analyses. The IAEA's Incident Reporting System contains more than 3000 reported operational events. Even though deterministic analyses were certainly performed for some of them, only a few reports are supplemented by the results of the computer code analysis. From 23-26 May 2005 a Technical Meeting on Deterministic Analysis of Operational Events in Nuclear Power Plants was organized by the IAEA and held at the International Centre of Croatian Universities in Dubrovnik, Croatia. The objective of the meeting was to provide an international forum for presentations and discussions on how deterministic analysis can be utilized for the evaluation of operational events at nuclear power plants in addition to the traditional root cause evaluation methods

    After the Cold War was put to an end, the international community, especially the Western world, was concerned about Soviet nuclear materials falling into wrong hands, especially of terrorists. Later, the growing threat posed by terrorist networks such as the Taliban and al Qaeda led to a global campaign to deny such networks materials which may be used for the development of Weapons of Mass Destruction (WMD). The 9 11 attacks made a section of the international community highly apprehensive of WMD terrorism, especially its nuclear version. From this point of view, it is clear that nuclear facilities which contain nuclear materials are very attractive targets for those who have intention of nuclear terror

    2007-01-01

    Full text: The fast decrease of coal, oil and natural gas as energy resources is pushing the world towards the use of nuclear energy. The expectation of growth in the nuclear field seems to be a great challenge -specially- in developing countries which are in hard need of acquiring nuclear knowledge and nuclear technology as well. In this situation, various factors would have great influence on the implementation of nuclear projects -in particular- for electricity generation. As a matter of fact, it is essential for each country to have its own strategy for national development. In practice, the implementation of such a strategy would need the collective efforts of specialized and efficient human resources for executing the tasks. This would need cooperation with, and/or technical aid of developed countries and international organizations. There are various parameters that may contribute in the national development in a country, the most important of which are the development in science and technology. Then, the industrial development becomes essential for the nuclear industry. In order to achieve this, the information acquiring and knowledge transfer are fundamental tools. The partnership between developed and developing countries would mean cooperation and aid directed to nuclear technology and knowledge transfer; and specialized technical training in the nuclear industry. Supplier countries might need to use high technology in implementing nuclear safeguards commitments, but with minimum side effects. This paper investigates some factors that may have influence on transferring peaceful uses of nuclear knowledge and/or nuclear technology; such as establishing and sustaining the national nuclear workforce, building of public understanding and public acceptance of nuclear science and technology. Also, it discusses the importance of activating and strengthening the international regime of partnership for the welfare and prosperity of human kind; with specific

    Bertucio, R.C.; Julius, J.A.; Cramond, W.R.

    1990-04-01

    This document contains the accident sequence analysis of internally initiated events for the Surry Nuclear Station, Unit 1. This is one of the five plant analyses conducted as part of the NUREG-1150 effort by the Nuclear Regulatory Commission. NUREG-1150 documents the risk of a selected group of nuclear power plants. The work performed and described here is an extensive of that published in November 1986 as NUREG/CR-4450, Volume 3. It addresses comments form numerous reviewers and significant changes to the plant systems and procedures made since the first report. The uncertainty analysis and presentation of results are also much improved. The context and detail of this report are directed toward PRA practitioners who need to know how the work was performed and the details for use in further studies. The mean core damage frequency at Surry was calculated to be 4.05-E-5 per year, with a 95% upper bound of 1.34E-4 and 5% lower bound of 6.8E-6 per year. Station blackout type accidents (loss of all AC power) were the largest contributors to the core damage frequency, accounting for approximately 68% of the total. The next type of dominant contributors were Loss of Coolant Accidents (LOCAs). These sequences account for 15% of core damage frequency. No other type of sequence accounts for more than 10% of core damage frequency. 49 refs., 52 figs., 70 tabs

    This paper proposes the establishment of a new, globally integrated approach for dealing with spent nuclear fuel (SNF), high-level waste, and plutonium supplies. The end product is envisioned to be a new global agency (tentatively called the International Nuclear Waste Authority, or INWA), which would have the authority to establish and enforce all nuclear waste disposal standards and subsequently execute all financial arrangements appropriate for obtaining full-scale global implementation. We suggest the IAEA as the logical existing organization to facilitate generating the structure for the INWA. (author)

    Stanley, Elizabeth A. (Georgetown Universtiy, Washington, DC)

    2006-02-01

    The report presents a summary of international perceptions and beliefs about US nuclear policy, focusing on four countries--China, Iran, Pakistan and Germany--chosen because they span the spectrum of states with which the United States has relationships. A paradox is pointed out: that although the goal of US nuclear policy is to make the United States and its allies safer through a policy of deterrence, international perceptions of US nuclear policy may actually be making the US less safe by eroding its soft power and global leadership position. Broadly held perceptions include a pattern of US hypocrisy and double standards--one set for the US and its allies, and another set for all others. Importantly, the US nuclear posture is not seen in a vacuum, but as one piece of the United States behavior on the world stage. Because of this, the potential direct side effects of any negative international perceptions of US nuclear policy can be somewhat mitigated, dependent on other US policies and actions. The more indirect and long term relation of US nuclear policy to US international reputation and soft power, however, matters immensely to successful multilateral and proactive engagement on other pressing global issues.

  12. Liability for nuclear damage. An international perspective

    International Nuclear Information System (INIS)

    Lopuski, J.

    1993-01-01

    The book deals with some of the complex issues of liability and compensation for nuclear damage which have been considered in the course of the work of the IAEA concerning the revision of the Vienna Convention on nuclear liability. It presents, in an orderly way, personal reflections of its author based on this experience gathered in years 1989-1992 when participating in this work. Necessarily it contains in some of its parts references to documents of the IAEA Standing Committee on Nuclear Liability; these documents because of their length could not be reproduced. Consequently these parts may be fully intelligible for those who have not participated in or closely followed in Committee's work. The IAEA work on liability for nuclear damage was initiated in the wake of the impact made on the world's public opinion by the Chernobyl incident and its transboundary effects; issues of international state liability and full compensation have been raised. But humanitarian ideas have quickly been confronted with cold calculations of the cost of financial protection for victims and an open unwillingness of some nuclear states the engage their liability; conflict of interests between nuclear and non-nuclear states has been manifested. After three years of discussion no wide consensus could be reached on some basic issues, such as: relationship between international state and civil liability regimes, structures of international legislation, concept of nuclear damage, limits of compensation, role of public funds or jurisdiction. The author presents his approach to these controversial issues, trying to provide at the same time a theoretical outline for the future international legislation on nuclear liability. (author)

    The evolution of the system created in a high energy nuclear collision is very sensitive to the fluctuations in the initial geometry of the system. In this letter we show how one can utilize these large fluctuations to select events corresponding to a specific initial shape. Such an "event shape engineering" opens many new possibilities in quantitative test of the theory of high energy nuclear collisions and understanding the properties of high density hot QCD matter.

  19. Nuclear energy: exit or revival? International aspects

    International Nuclear Information System (INIS)

    2001-11-01

    This colloquium took place less than 1 year after the decision of the US of revival of their nuclear program. Thus the international context has changed, even if nuclear contestation remains as strong as in the past. Among governments, some positions preach the banishment of nuclear energy while others consider the nuclear option as the only solution to meet the growing up energy demand and the future environmental and economical stakes. This report makes a synthesis of the different talks given by the participants during the 3 round tables of the colloquium on the future of nuclear energy: the ecological stake, the democratic stake, and the energy policy stake. Four talks of French government representatives open and conclude the debates of the different round tables. (J.S.)

    Event-based biosurveillance is a scientific discipline in which diverse sources of data, many of which are available from the Internet, are characterized prospectively to provide information on infectious disease events. Biosurveillance complements traditional public health surveillance to provide both early warning of infectious disease events and situational awareness. The Global Health Security Action Group of the Global Health Security Initiative is developing a biosurveillance capability that integrates and leverages component systems from member nations. This work discusses these biosurveillance systems and identifies needed future studies.

  6. Nuclear facility safeguards systems modeling using discrete event simulation

    Engi, D.

    1977-01-01

    The threat of theft or dispersal of special nuclear material at a nuclear facility is treated by studying the temporal relationships between adversaries having authorized access to the facility (insiders) and safeguards system events by using a GASP IV discrete event simulation. The safeguards system events--detection, assessment, delay, communications, and neutralization--are modeled for the general insider adversary strategy which includes degradation of the safeguards system elements followed by an attempt to steal or disperse special nuclear material. The performance measure used in the analysis is the estimated probability of safeguards system success in countering the adversary based upon a predetermined set of adversary actions. An exemplary problem which includes generated results is presented for a hypothetical nuclear facility. The results illustrate representative information that could be utilized by safeguards decision-makers

    Terrorism remains a threat to international stability and security. High profile international and national major public events occur regularly, capturing great public interest and receiving intense media coverage. It is widely acknowledged that there is a substantial threat of a terrorist attack on major public events such as high profile political or economic summit meetings or major sporting contests. The threat of nuclear and radiological terrorism remains on the international security agenda. Nevertheless, to reduce this risk, the international community has made great progress in securing nuclear and other radioactive material that could otherwise be used in a terrorist act. This progress is contingent on the efforts of all States to adopt strong nuclear security systems and measures. There are large quantities of diverse radioactive material in existence, which are used in areas such as health, the environment, agriculture and industry. The hazards of this material vary according to composition and intensity. Additionally, the use of explosives in combination with this material can drastically enhance the impact of a criminal or terrorist act. If a criminal or terrorist group managed to detonate a so-called 'dirty' bomb in an urban area, the result could be mass panic, widespread radioactive contamination and major economic and social disruption. Major public events are seldom held in the same State or at the same location or even at the same venue. At the national level, the hosting of major public events with proper nuclear security arrangements can provide a foundation on which to build an enduring national framework for nuclear security; one that can exist long after the event. The organization of a major public event in which large numbers of people congregate presents complex security challenges for the State hosting such an event. Criminal or terrorist acts involving nuclear or other radioactive material at any major public event could result in

    1988-09-28

    Nuclear safeguards applied by the International Atomic Energy Agency (IAEA) are one element of the non-proliferation regime'', the collection of measures whose aim is to forestall the spread of nuclear weapons to countries that do not already possess them. Safeguards verifications provide evidence that nuclear materials in peaceful use for nuclear-power production are properly accounted for. Though carried out in cooperation with nuclear facility operators, the verifications can provide assurance because they are designed with the capability to detect diversion, should it occur. Traditional safeguards verification measures conducted by inspectors of the IAEA include book auditing; counting and identifying containers of nuclear material; measuring nuclear material; photographic and video surveillance; and sealing. Novel approaches to achieve greater efficiency and effectiveness in safeguards verifications are under investigation as the number and complexity of nuclear facilities grow. These include the zone approach, which entails carrying out verifications for groups of facilities collectively, and randomization approach, which entails carrying out entire inspection visits some fraction of the time on a random basis. Both approaches show promise in particular situations, but, like traditional measures, must be tested to ensure their practical utility. These approaches are covered on this report. 15 refs., 16 figs., 3 tabs.

    Many elements can bear on liability for nuclear damage during transport. For example, liability may depend upon a number of facts that may be categorized as follows: shipment, origin or destination of the shipment, deviation from the planed route, temporary storage incidental to carriage; content of shipment, type of nuclear material involved, whether its origin is civilian or defence-related; sites of accident, number and type of territories damaged (i.e. potential conventions involved), applicable territorial limits, exclusive economic zone, high seas, etc.; nature of damages, personal injury, property damage, damage to the means of carriage, indirect damage, preventive measures, environmental cleanup or retrieval at seas, res communis, transboundary damages etc.; victims involved, nationality and domiciles of victims; jurisdiction, flag (for ships) or national registration (for aircraft) of the transporting vessel, courts of one or more states may have (or assert) jurisdiction to hear claims, and may have to determine what law to apply to a particular accident; applicable law, the applicability laws and/or international nuclear liability conventions; the extent to which any applicable convention has been implemented or modified by domestic legislation, conflicts with the 1982 Law of the Sea Convention or other applicable international agreements, and finally, also written agreements between installation operators and carriers can define applicable law as well as responsibilities. Harmonizing nuclear liability protection and applying it to additional international shipments would be facilitated by more countries being in treaty relations with each other as soon as possible. Adherence to an international convention by more countries (including China, Russia, the United States, etc.) would promote the open flow of services and advanced technology, and better facilitate international transport. The conventions protect the public, harmonize legislation in the

    In July 1995, the German Federal Ministry for the Environment, Nature Conservation, and Reactor Safety (BMU) presented the 1994 survey of 'Notifiable Events in Plants for Nuclear Fuel Fission - Nuclear Power Plants and Research Reactors Whose Maximum Power Exceeds 50 kW of Continuous Thermal Power - in the Federal Republic of Germany'. Since 1975, the operators of nuclear power plants in the Federal Republic of Germany have been required to report to the nuclear supervisory authorities all notifiable events in accordance with standard national reporting criteria. This official reporting system serves for monitoring the safety status of notifiable plants and use the findings derived from the events reported to improve the safety status of plants within the supervisory procedures where necessary. The reports constitute an important base for the early detection of defects and for preventing the occurrence of similar defects in other plants. In 1994, there were 161 notifiable events in nuclear power plants in the Federal Republic of Germany. None of these events is to be classified as an accident, and in none of the events were dose limits under the German Radiation Protection Ordinance exceeded. (orig.) [de

    As an integral part of DOE's International Nuclear Safety Center (INSC) at Argonne National Laboratory, the INSC Database has been established to provide an interactively accessible information resource for the world's nuclear facilities and to promote free and open exchange of nuclear safety information among nations. The INSC Database is a comprehensive resource database aimed at a scope and level of detail suitable for safety analysis and risk evaluation for the world's nuclear power plants and facilities. It also provides an electronic forum for international collaborative safety research for the Department of Energy and its international partners. The database is intended to provide plant design information, material properties, computational tools, and results of safety analysis. Initial emphasis in data gathering is given to Soviet-designed reactors in Russia, the former Soviet Union, and Eastern Europe. The implementation is performed under the Oracle database management system, and the World Wide Web is used to serve as the access path for remote users. An interface between the Oracle database and the Web server is established through a custom designed Web-Oracle gateway which is used mainly to perform queries on the stored data in the database tables

  2. 10. anniversary International School of Nuclear Law

    International Nuclear Information System (INIS)

    2010-01-01

    In August 2010, the International School of Nuclear Law (ISNL) will hold its 10. anniversary session. It has already been a decade since the Nuclear Energy Agency, in co-operation with the University of Montpellier 1 in France, decided to establish a 'summer university' programme to teach international nuclear law. The major impetus for doing so largely resulted from the fact that university law faculties at that time did not offer specialized courses in nuclear law, a situation that has not changed significantly over the years despite the recent and growing interest of the international community in nuclear energy production. The founders of the ISNL, Mr. Patrick Reyners formerly of the Nuclear Energy Agency and Professor Pierre Bringuier from the University of Montpellier 1, embarked on this experiment as an attempt to fill this educational gap, at least at the international level, and they each obtained significant support for the project from their respective institutions. Nuclear law is one of the most highly technical and thus often difficult areas in the legal discipline. Yet, the highly regulated nature of nuclear activities, both at national and international levels, demands that legal practitioners develop both expertise in drafting and interpreting the large number and wide variety of associated legal instruments. At the start of the 21. century, comprehensive national and international legal frameworks covering virtually all aspects of nuclear activities existed in all developed countries without an equivalent educational programme to teach future generations. Although the success of the school in its early days was difficult to predict, we can now proudly state that the ISNL has been, and continues to be, a great achievement with a reputation for excellence that spans six continents. The ISNL team is a professional collaboration, not only between the NEA and the University of Montpellier 1, but between the organizers, lecturers and participants of each

    Nuclear power plant buildings must be functional to such an extend that even after the occurence of extraordinary events (earthquake, airoplane crash, gas cloud explosion), the reactor can be safety shut off, in order to avoid danger from the nuclear power plant. Evidence for this can only be given by calculations which shall meet the following requirements: The calculation results shall be safe and reliable. The calculation effort shall match the realizable accuracy. The calculation shall lead to an economical determination. An example of ascertainment of nuclear power plants in regard to earthquakes, shows the difficulties standing against a fulfillment of these requirements. (orig.) [de

    1982-01-01

    These notes for the postgraduate course on Radiological Protection and Nuclear Safety deal with the effects produced by some human activities on the siting and design of a nuclear installation. The existing activities, as well as the foreseen or foreseeable future ones are evaluated. In the first place, the potential sources of events are identified and classified in two categories: stationary and mobile, and the events are classified in five groups: 1) Aircraft crash; 2) Chemical explosions; 3) Discharge of dangerous fluids (explosive, toxic or corrosive); 4) Fire, and 5) Sabotage, terrorism, guerrillas. Then, the effects which may result from these events and affect the nuclear installation are studied: 1) pressure waves; 2) Impact of missiles; 3) Heat, fire; 4) Smoke and dust; 5) Gas or inflammable and/or explosive dust clouds; 6) Toxic and/or corrosive gases and liquids; 7) Ground shaking; 8) Flooding or lack of water; 9) Foundations failure or collapse. Next, the methods for making a deterministic and/or a probabilistic study (or both) are indicated for each event considered, and from these studies the ''screening'' values which allow to determine if an event can be rejected or must be considered are established. For this second case, the method for obtaining the ''design event'' that shall serve as a basis for the design of the plant is indicated. (M.E.L.) [es

    Safeguarding of nuclear power plants against disruptive actions or other external hazards is part of the plant design and presumption of an operation license. The general principle is defense in depth involving different security zones with separate barriers. The safeguards for nuclear installations are organized in three areas of responsibility: governmental measures (police, military), technical (detectors, scanners, illuminations, camera tracking, concrete barriers) and personnel measures (access control, security personnel, alarm) of the operating company. International responsibilities results from the treaty on the non-proliferation of nuclear weapons and several IAEA documents. The authors discuss the national regulations in Germany, Switzerland, United Kingdom and USA. Older NPPs that are not in compliance with actual safety standards will be a topic of increasing importance.

    Internal dosimetry which refers to dosage estimation from internal part of an individual body is an important and compulsory component in order to ensure the safety of the personnel involved in operational of a Nuclear Power Program. Radionuclides particle may deposit in the human being through several pathways and release wave and/or particle radiation to irradiate that person and give dose to body until it been excreted or completely decayed from the body. Type of radionuclides of concerning, monitoring program, equipment's and technique used to measure the concentration level of such radionuclides and dose calculation will be discussed in this article along with the role and capability of Malaysian Nuclear Agency.

    For over 50 years stopping nuclear weapon tests has been sought to support achieving international security without nuclear weapons. Testing is the critical path beyond primitive fission devices, e.g. to develop thermonuclear weapons, reduce weight and volume and increase yield. The 1958 Geneva Conference of Experts considered ways to verify a test ban. With then-limitations on seismology, and lack of in-country monitoring and on-site inspections, the 1963 Limited Test Ban Treaty prohibits testing only in the atmosphere, outer space and under water, and is verified by National Technical Means. The US and USSR agreed to a limit of 150 kilotons on underground explosions in the 1970s-80s. The 1996 Comprehensive Nuclear-Test-Ban Treaty bans all nuclear explosions. Its International Monitoring System - seismic, hydroacoustic, infrasound and radionuclide sensors - is being used, and has easily detected testing by the DPRK. On-site inspections will be available under an in-force Treaty. A 2012 National Academy report concludes that cheating attempts would not undermine U.S. security, and the program for monitoring and extending the life of US weapons has succeeded since US testing ceased in 1992.

    The International School of Nuclear Law (ISNL) was established in 2000 by the OECD Nuclear Energy Agency and the University of Montpellier 1. It benefits from the support of the International Nuclear Law Association (INLA) and the International Atomic Energy Agency (IAEA). The school offers a high-quality educational programme acknowledged for its intensive courses, professional lecturers, as well as its academic and practical balance. In the past seven years, the ISNL has been attended by approximately 400 participants from 78 countries around the world. The NEA awards scholarships to enable certain meritorious students from its member countries to benefit from the course. The IAEA also awards a number of fellowships to participants from its member countries. This helps ensure broad representation from different countries and bestows the ISNL with the different views, experience and legal backgrounds of its participants. The applicants are mostly but not necessarily lawyers. Such diversity is welcomed as the interdisciplinary composition of classes contributes to the dialogue and mutual learning between lawyers and scientists or economists for example. (author)

    1999-01-01

    A water hammer issue in nuclear power plants was one of unresolved safety issues listed by the United States Nuclear Regulatory Commission and was regarded as resolved. But later on, the water hammer events are still experienced intermittently, while the number of the events is decreasing. We collected water hammer events of PWRs in Japan and the United States and relevant documents, analyzed them, and studied corrective actions taken by Japanese plants. As a result, it is confirmed that preventive measured in design, operation etc. have been already taken and that mitigation mechanisms against water hammer have also been considered. However, it is clarified that attention should be continuously paid to operation of valves and/or pumps, as the prevention of water hammer still relies on operation. (author)

    1973-01-01

    The International Nuclear Information System (INIS) is the world's first computer-based international documentation service for which input is prepared on a decentralized basis. It was set up co-operatively by the International Atomic Energy Agency and its Member States, within the Agency's Division of Scientific and Technical Information, to construct a data base identifying publications relating to nuclear science and its peaceful applications; it commenced operation in May 1970. Each participating Member State and international and regional organization is responsible for scanning the scientific and technical literature it produces and reporting the input data for INIS to the IAEA. Since INIS is a world-wide information system and highly decentralized, standards for preparing the INIS document input were formulated to take into account the requirements and practices of the participants. These standards are laid down in the INIS Reference Series Nos 1-13. In addition, training seminars on input preparation are held both in Vienna and abroad, and individual trainees from participating Member States take courses at the IAEA Headquarters in Vienna. Although English has been adopted as the working language of INIS, abstracts are accepted in any of the four IAEA official languages - English, French, Russian and Spanish - and non-conventional literature in the original language

    1994-07-01

    DOE is committed to providing technologies to the International Atomic Energy Agency (IAEA) to meet escalating monitoring and inspection requirements associated with the Non-Proliferation Treaty (NPT). One example of technology provided to the IAEA is the information management and remote monitoring capabilities being customized for the IAEA by the International Safeguards Division of the Office of Non-Proliferation and National Security. The ongoing Safeguards Information Management Systems (SIMS) program is an interlaboratory effort providing the IAEA with a range of information management capabilities designed to enhance the effectiveness of their nuclear inspection activities. The initial commitment involved the customization of computer capabilities to provide IAEA with the basic capability to geographically organize, store, and retrieve the large quantity of information involved in their nuclear on site inspection activities in Iraq. This initial system, the International Nuclear Safeguards Inspection Support Tool (INSIST), was developed by DOE's Pacific Northwest Laboratory (PNL). To date, two INSIST workstations have been deployed at the IAEA. The first has been used to support the IAEA Action Team in the inspection of Iraqi nuclear facilities since August 1993. A second, and similar, workstation has been deployed to support environmental monitoring under the IAEA 93+2 Programme. Both INSIST workstations geographically integrate analog (video) and digital data to provide an easy to use and effective tool for storing retrieving and displaying multimedia site and facility information including world-wide maps, satellite and aerial imagery, on site photography, live inspection videos, and treaty and inspection textual information. The interactive, UNIX-based workstations have a variety of peripheral devices for information input and output. INSIST software includes commercial-off-the-shelf (COTS) modules and application-specific code developed at PNL

  2. International nuclear safeguards 1994: Vision for the future. V.1

    International Nuclear Information System (INIS)

    1994-01-01

    Since the last IAEA symposium on this subject, held eight years ego in 1986, the world of safeguards has experienced a number of momentous changes which have opened a new period of intensive development in safeguards. The important events were: The discoveries in Iraq during activities under United Nations Security Council resolutions, South Africa's decision to become a party to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the IAEA-Argentina-Brazil-ABACC Quadripartite Safeguards Agreement, the break-up of the former USSR into newly independent States, and the problems encountered in the implementation of NPT safeguards in the Democratic People's Republic of Korea. The consequences for international safeguards of these events were presented in papers at this symposium, with special emphasis on verification of a State's declaration as well as on detection of undeclared activities. Other fundamental changes stem from converging relationships between nuclear arms reductions and the civil use of plutonium, and the international debate on the associated issues. Furthermore, the review and extension of the NPT is due in 1995. Events have opened the possibility for ambitious new concepts for verification regimes. These matters were addressed at the symposium in the opening session and in the closing panel discussion. Refs, figs and tabs

    Wheelis, W.T.

    2001-01-01

    1 - Description of program or function: FIREDATA contains raw fire event data from 1965 through June 1985. These data were obtained from a number of reference sources including the American Nuclear Insurers, Licensee Event Reports, Nuclear Power Experience, Electric Power Research Institute Fire Loss Data and then collated into one database developed in the personal computer database management system, dBASE III. FIREDATA is menu-driven and asks interactive questions of the user that allow searching of the database for various aspects of a fire such as: location, mode of plant operation at the time of the fire, means of detection and suppression, dollar loss, etc. Other features include the capability of searching for single or multiple criteria (using Boolean 'and' or 'or' logical operations), user-defined keyword searches of fire event descriptions, summary displays of fire event data by plant name of calendar date, and options for calculating the years of operating experience for all commercial nuclear power plants from any user-specified date and the ability to display general plant information. 2 - Method of solution: The six database files used to store nuclear power plant fire event information, FIRE, DESC, SUM, OPEXPER, OPEXBWR, and EXPERPWR, are accessed by software to display information meeting user-specified criteria or to perform numerical calculations (e.g., to determine the operating experience of a nuclear plant). FIRE contains specific searchable data relating to each of 354 fire events. A keyword concept is used to search each of the 31 separate entries or fields. DESC contains written descriptions of each of the fire events. SUM holds basic plant information for all plants proposed, under construction, in operation, or decommissioned. This includes the initial criticality and commercial operation dates, the physical location of the plant, and its operating capacity. OPEXPER contains date information and data on how various plant locations are

    German nuclear power plants are characterized by a high degree of automation, not only for normal operation but also for abnormal events. Therefore the role of the operating personnel is mainly a supervisory function. Nevertheless, for a spectrum of unexpected events the operating personnel have to react with manual recovery actions. In order to minimize human error in such recovery actions, different kinds of intelligent decision aid support the operators today. In this paper such aids are discussed and one of them is described in more detail. (author)

    2004-01-01

    Nuclear power is a significant contributor to the global supply of electricity, and continues to be the major source that can provide electricity on a large scale with a comparatively minimal impact on the environment. But it is evident that, despite decades of experience with this technology, nuclear power today remains mainly in a holding position, with its future somewhat uncertain primarily due to concerns related to waste, safety and security. One of the most important factors that would influence future nuclear growth is the innovation in reactor and fuel cycle technologies to successfully maximize the benefits of nuclear power while minimizing the associated concerns. The main objectives of the Conference were to facilitate exchange of information between senior experts and policy makers from Member States and international organizations on important aspects of the development of innovative technologies for future generations of nuclear power reactors and fuel cycles; to create an understanding of the social, environmental and economic conditions that would facilitate innovative and sustainable nuclear technologies; and to identify opportunities for collaborative work between Member States and international organizations and programmes. All relevant aspects of innovative technologies for nuclear fuel cycles and nuclear power were discussed in an open, frank and objective manner. These proceedings contain a summary of the results of the conference, invited and contributed papers, and summaries of panel discussions. No large increase in the use of nuclear energy is foreseen in the near and medium term, but is likely in the long term if developing country per-capita electricity consumption reaches that of the developed world. The nuclear sector including regulators view an increased use of nuclear energy as the solution for global sustainable energy needs considering that significant reductions in CO 2 emissions would be required. Although the current nuclear

    International collaboration, eg on the Superphenix and SNR 300 fast breeder reactors, is seen as a good thing. However, the question is asked whether the collaboration extends to the licensing procedure. Is this the reason why in some countries nuclear programmes flourish, whereas in others there are delays? The structure of the licensing procedures in the United Kingdom, France and West Germany is compared. The different licensing procedures only have a limited effect on the outcome of the fast breeder programme. The differences lie in the centralised or federal government structure and different socio-political aspects. However, these are reflected in licensing procedures. Means of international collaboration within the licensing framework are suggested, but may be difficult to achieve yet. A major step forward would be to develop uniform safety standards for the licensing procedure and to make sure each country complies with them. (U.K.)

    Democratic People's Republic of Korea(DPRK) carried out 6th nuclear test on 3 Sep. 2017 at 03:30 UTC. Korea Meteorological Administration(KMA) announced to the public that the event took place in the DPRK's test site, Punggye-ri with the magnitude 5.7. This event is larger than previous one in terms of magnitude and showed that measured magnitude strongly depends on the frequency band of data. After we applied several magnitude scales such as Everdon(1967), Nuttli(1967), and Hong & Lee(2012) to this event, we found that magnitude ranges from 5.3 to 6.7 which depends on frequency band and epicentral distance of signal. 6th DPRK test experiment indicated that spectral amplitude ratio of 6th/5th near 2.37 Hz shows similar amplification compatible to relative spectral magnitude 5.7, while spectral amplitude ratio of 6th/5th near 1.0 Hz marks relative spectral magnitude about 6.1. Relative spectral magnitude varies with frequencies and decreases as frequency increase. We found that systematic non-linearity exists for spectral amplitude ratio of 6th/5th from 1.0 to 10.0 Hz, while it's characteristic is not found at 5th/4th and 4th/3th. A methodology is presented for determining mb(Pn) magnitude of underground nuclear explosions from local Pn phase. 582 waveforms from vertical component of broadband and acceleration seismographs at 120 stations in the epicenter distance from 340 to 800 km are used to calibrate mb(Pn) magnitude scaling for DPRK's nuclear tests. The mb(Pn) estimates of regional events for Korean Peninsula are determined to be mb(Pn) ? = log10(A) + 2.1164×log10(d) - 0.2721, where A is the peak-to-peak Pn amplitude in μm and d is the epicentral distance in km. Systematic non-linearity does not observed at frequency band from 0.1 to 1.0 Hz. The magnitude of 6th event is mb(Pn) 6.08 and mb(Pn) 4.52, 4.92, 4.84 and 5.03 for 2nd, 3rd, 4th and 5th respectively. Further research of applicable mb(Pn) magnitude scaling is required for all frequency band and

  11. Trend analysis of fire events at nuclear power plants

    We performed trend analyses to compare fire events occurring overseas (1995-2005) and in Japan (1966-2006). We decided to do this after extracting data on incidents (storms, heavy rain, tsunamis, fires, etc.) occurring at overseas nuclear power plants from the Events Occurred at Overseas Nuclear Power Plants recorded in the Nuclear Information Database at the Institute of Nuclear Safety System (INSS) and finding that fires were the most common of the incidents. Analyses compared the number of fires occurring domestically and overseas and analyzed their causes and the effect of the fires on the power plants. As a result, we found that electrical fires caused by such things as current overheating and electric arcing, account for over one half of the domestic and overseas incidents of fire, which indicates that maintenance management of electric facilities is the most important aspect of fire prevention. Also, roughly the same number of operational fires occurred at domestic and overseas plants, judging from the figures for annual occurrences per unit. However, the overall number of fires per unit at domestic facilities is one fourth that of overseas facilities. We surmise that, while management of operations that utilizes fire is comparable for overseas and domestic plants, this disparity results from differences in the way maintenance is carried out at facilities.

On the one hand, the exceptional event represents a factor which speeds up urban transformations, that could not be realized otherwise. This characteristic has been defined as “pulsar effect” to explicate the impulse given to normal course of urban living by the mega events. On the other hand, mega events ask for actions aimed at managing the intense displacements due to their organizations and attractive capacity. Among the different types of events, this study considers the Universal Expositions, as they have been defined by the Bureau International des Expositions (the non-governmental organization having the decision power about great exposition. Universal or International Expo’s realization affects specific urban areas, interested by important transformations, especially referred to realization of infrastructure (mobility or dedicated to the event. While the management of urban mobility requires to define specific actions aimed at traffic congestion minimization. Increasing transport demand (visitors and tourists + residents and city-users is one of mega event effects.

    INIS is the worlds leading decentralized information system on the peaceful uses of nuclear energy. It is operated by the International Atomic Energy Agency in co-operation with the member states and international organisations. Being one of the INIS member states, our country has began co-operation with INIS in 1975. INIS National Centre is acting within the Institute of Nuclear Sciences and according to the strictly defined organisation of the information system supplies the users with the available INIS products, meaning bibliographic data from the INIS data base. At the same time it is responsible for submitting information concerning domestic publications to the INIS Secretariat, including supplying foreign users with non-conventional literature if demanded. During the period 1990 - 1996 co-operation with INIS Secretariat was interrupted due to reasons which are not subject of this paper. Since then collaboration is established again, and updated INIS data base on CD-ROM is available at the National Centre. INIS on-line retrieval is not yet available

    2007-07-01

    The important role which the International Atomic Energy Agency (IAEA) plays in assisting Member States in the preservation and enhancement of nuclear knowledge and in facilitating international collaboration in this area has been recognized by the General Conference of the International Atomic Energy Agency in resolutions GC(46)/RES/11B, GC(47)/RES/10B, GC(48)/RES/13 and GC(50)/RES/13. The IAEA continues to support the enhancement and stabilization of nuclear education and training with the objective of securing the availability of qualified human resources for the nuclear sector. Its most important approaches are networking regional educational institutions and fostering cooperation to develop harmonized curricula, prepare and disseminate teaching materials. The Asian Network for Education in Nuclear Technology (ANENT), established by the IAEA in 2004, became operational in 2005. An ANENT website has been set up and is being expanded, such as developing a long-distance learning platform. Also, a reference curriculum for nuclear engineering is being developed with the cooperation of external partners.This booklet summarizes the main activities being carried out by the IAEA with regard to the Asian Network for Education in Nuclear Technology (ANENT) and other related activities including those completed during the period 2002–2005. It briefly describes the background information on the events leading to the formation of the ANENT; the terms of reference formulated at the second Coordination Committee meeting held in Vietnam, October 2005; and objectives, strategy and other institutional and managerial policies reaffirmed by the members.

    2016-01-01

    Throughout history, and throughout the world, groundwater has been a major source of water for sustaining human life. Use of this resource has increased dramatically over the last century. In many areas of the world, the balance between human and ecosystem needs is difficult to maintain. Understanding the international scale of the groundwater issue requires metrics and analysis at a commensurate scale. Advances in remote sensing supplement older traditional direct measurement methods for understanding the magnitude of depletion, and all measurements motivate the need for common data standards to collect and share information. In addition to metrics of groundwater availability, four key international groundwater issues are depletion of water, degradation of water quality, the water-energy nexus, and transboundary water conflicts. This chapter is devoted to introducing these issues, which are also discussed in more detail in later chapters.

    1980-06-01

    Some possible hydrogeologic effects of disruptive events that may affect repositories for nuclear waste are described. A very large number of combinations of natural events can be imagined, but only those events which are judged to be most probable are covered. Waste-induced effects are not considered. The disruptive events discussed above are placed into four geologic settings. Although the geology is not specific to given repository sites that have been considered by other agencies, the geology has been generalized from actual field data and is, therefore, considered to be physically reasonable. The geologic settings considered are: (1) interior salt domes of the Gulf Coast, (2) bedded salt of southeastern New Mexico, (3) argillaceous rocks of southern Nevanda, and (4) granitic stocks of the Basin and Range Province. Log-normal distributions of permeabilities of rock units are given for each region. Chapters are devoted to: poresity and permeability of natural materials, regional flow patterns, disruptive events (faulting, dissolution of rock forming minerals, fracturing from various causes, rapid changes of hydraulic regimen); possible hydrologic effects of disruptive events; and hydraulic fracturing

    ). The report is aimed not only at international regulatory agencies, national governments, an d nuclear plant operators, but at all those who are seriously concerned with the safety of nuclear energy activities. Its message is simple: a nuclear disaster on the scale of Chernobyl must never be allowed to happen again; high levels of nuclear safety assurance must be demonstrated in all countries at an international level in view of widespread and legitimate public scepticism about the safety and the acceptability of nuclear power. The ICFTU has strong views about the need for worldwide nuclear disarmament and has recently published a report on its efforts to promote peace, security and disarmament. The military applications of nuclear technology are however beyond the scope of this report which is concerned only with the control of the nuclear power generating industry and with civil research reactors. We believe that the recommendations it contains deserve thorough consideration by governments, and indeed by all those concerned with the large and still growing use of nuclear power

  1. Trending of low level events and near misses to enhance safety performance in nuclear power plants

    International Nuclear Information System (INIS)

    2005-11-01

    The IAEA Safety Fundamentals publication, Safety of Nuclear Installations, Safety Series No. 110, states the need for operating organizations to establish a programme for the collection and analysis of operating experience in nuclear power plants. Such a programme ensures that operating experience is analysed, events important to safety are reviewed in depth, and lessons learned are disseminated to the staff of the organization and to relevant national and international organizations. As a result of the effort to enhance safety in operating organizations, incidents are progressively decreasing in number and significance. This means that in accordance with international reporting requirements the amount of collected data becomes less sufficient to draw meaningful statistical conclusions. This is where the collection and trend analysis of low level events and near misses can prove to be very useful. These trends can show which of the safety barriers are weak or failing more frequently. Evaluation and trending of low level events and near misses will help to prevent major incidents because latent weaknesses have been identified and corrective actions taken to prevent recurrence. This leads to improved safety and production. Low level events and near misses, which may reach several thousand per reactor operating year, need to be treated by the organizations as learning opportunities. A system for capturing these low level events and near misses truly needs to be an organization-wide system in which all levels of the organization, including contractors, participate. It is desirable that the overall operational experience feedback (OEF) process should integrate the lessons learned and the associated data from significant events with those of lower level events and near misses. To be able to effectively implement a process dealing with low level events and near misses, it is necessary that the organization have a well established OEF process for significant events

    The U.S. Geological Survey National Earthquake Information Center (NEIC) monitors seismicity on local, regional, and global scales using automatic picks from more than 2,000 near-real time seismic stations. This presents unique challenges in automated event detection due to the high variability in data quality, network geometries and density, and distance-dependent variability in observed seismic signals. To lower the overall detection threshold while minimizing false detection rates, NEIC has begun to test the incorporation of new detection and picking algorithms, including multiband (Lomax et al., 2012) and kurtosis (Baillard et al., 2014) pickers, and a new bayesian associator (Glass 3.0). The Glass 3.0 associator allows for simultaneous processing of variably scaled detection grids, each with a unique set of nucleation criteria (e.g., nucleation threshold, minimum associated picks, nucleation phases) to meet specific monitoring goals. We test the efficacy of these new tools on event detection in networks of various scales and geometries, compare our results with previous catalogs, and discuss lessons learned. For example, we find that on local and regional scales, rapid nucleation of small events may require event nucleation with both P and higher-amplitude secondary phases (e.g., S or Lg). We provide examples of the implementation of a scale-independent associator for an induced seismicity sequence (local-scale), a large aftershock sequence (regional-scale), and for monitoring global seismicity.

    1996-01-01

    Multilateral international agreements have defined the framework of behavior and cooperation in various fields and aspects of peaceful use of nuclear energy. Thus, obligations have been defined in the following areas: nonproliferation of nuclear weapons, physical protection of nuclear material, liability for nuclear damage, nuclear safety, early notification about a nuclear accident and assistance in case of nuclear accident. Obligations regarding radioactive waste management should be defined soon. This paper gives a review of obligations from particular agreements with a special emphasis on those which are being realized through mutual cooperation of concerned countries and are important for safe use of nuclear energy.

    1996-01-01

    The status of nuclear materials in both the U.S. and Former Soviet Union is changing based upon the execution of agreements relative to weapons materials production and weapon dismantlement. The result of these activities is that a considerably different emphasis is being placed on how nuclear materials are viewed and utilized. Even though much effort is being expended on the final disposition of these materials, the interim need for storage and security of the material is increasing. Both safety and security requirements exist to govern activities when these materials are placed in storage. These requirements are intended to provide confidence that the material is not being misused and that the storage operations are conducted safely. Both of these goals can be significantly enhanced if technological monitoring of the material is performed. This paper will briefly discuss the traditional manual methods of U.S. and international material monitoring and then present approaches and technology that are available to achieve the same goals under the evolving environment

    The aims of this study were to assess the internal reliability (internal consistency), construct validity, sensitivity and ceiling and floor effects of the Brazilian-Portuguese version of the Impact of Event Scale (IES). Methodological research design. The Brazilian-Portuguese version of the IES was applied to a group of 91 burned patients at three times: the first week after the burn injury (time one), between the fourth and the sixth months (time two) and between the ninth and the 12th months (time three). The internal consistency, construct validity (convergent and dimensionality), sensitivity and ceiling and floor effects were tested. Cronbach's alpha coefficients showed high internal consistency for the total scale (0·87) and for the domains intrusive thoughts (0·87) and avoidance responses (0·76). During the hospitalisation (time one), the scale showed low and positive correlations with pain measures immediately before (r=0·22; pnegative correlations with self-esteem (r=-0·52; plow and negative with the Bodily pain (r=-0·24; pimpact of the event in the group of patients under analysis. The Impact of Event Scale can be used in research and clinical practice to assess nursing interventions aimed at decreasing stress during rehabilitation. © 2011 Blackwell Publishing Ltd.

    It was a pleasure to welcome all delegates and accompanying persons to Adelaide for the 26th International Conference in Nuclear Physics, INPC2016. As the major meeting in our field, it was a wonderful opportunity to catch up with colleagues from around the world, learn about the very latest developments and share ideas. We were grateful for the support of the Commission on Nuclear Physics, C12, of the International Union of Pure and Applied Physics (IUPAP), which chose Adelaide to host this meeting. We were also honoured that the President of IUPAP, Prof. Bruce McKellar was present at the meeting to welcome delegates and participate in the proceedings. We acknowledge the financial support for the conference which was made available by a number of organisations. We were especially grateful to the major sponsors, the Adelaide Convention Bureau, the University of Adelaide, the Australian National University and ANSTO, as well as IUPAP, the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP) and several of the world's major nuclear physics laboratories, BNL, GSI, JLab and TRIUMF. As a result of these contributions we were able to offer support to attend the conference to more than 50 international students. Not only did we have a superb scientific program but, consistent with IUPAP guidelines, more than 40% of the invited plenary talks were presented by women. In order to reach out to the local community, Cynthia Keppel (from JLab) presented a public lecture on Hadron Beam Therapy on Tuesday evening, September 13th. As presenting a talk is now often a condition for financial support to attend an international conference, there were 11 simultaneous parallel sessions with more than 350 presentations. We are especially grateful to the International Advisory Committee, the Program Committee and the Conveners whose advice and hard work made it possible for all this to come together. I would also like to acknowledge the work of the Local Organising

    Gamma-ray line (GRL) and solar energetic proton (SEP) events observed from February 1980 through January 1985 are compared in order to substantiate and better characterize the lack of correlation between GRL fluences and SEP event peak fluxes. The scatter plot of SEP event peak flux vs. GRL fluence is presented, and the ratio of 'solar' to 'interplanetary', about 10 MeV protons, is presented. It is shown that, while even large SEP events can originate in flares lacking detectable GRL emission, the converse case of flares with a significant GRL line fluence by lacking protons in space is rare. The ratio R of the number of about 10 MeV protons that produce GRL emission at the flare site to the number of about 10 MeV protons detected in space can vary from event to event by four orders of magnitude. There is a clear tendency for impulsive flares to have larger values of R than long-duration flares, where the flare time scale is given by the e-folding decay time of the associated soft X-ray emission. 103 refs

    Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to determine accurate distances, using a wide range of methods, tracers, and techniques, an internally consistent astronomical distance framework has not yet been established. We review current efforts to homogenize the Local Group's distance framework, with particular emphasis on the potential of RR Lyrae stars as distance indicators, and attempt to extend this in an internally consistent manner to cosmological distances. Calibration based on Type Ia supernovae and distance determinations based on gravitational lensing represent particularly promising approaches. We provide a positive outlook to improvements to the status quo expected from future surveys, missions, and facilities. Astronomical distance determination has clearly reached maturity and near-consistency.

    1988-01-01

    German nuclear power plants are characterized by a high degree of automation, not only for normal operation but also for abnormal events. Therefore the role of the operating personnel is mainly a supervisory function. Nevertheless, for a spectrum of unexpected events the operating personnel have to react with manual recovery actions. In order to minimize human error in such recovery actions, different kinds of intelligent decision aid support the operators today. In this paper such aids are discussed and one of them integrated disturbance analysis, IDA, is described in more detail. It is applied in Biblis B reactor to the whole secondary circuit with special account of the condensate from the hotwell to the steam generator including all the support systems. (author)

    The Nuclear Smuggling International Technical Working Group (ITWG) is an international body of nuclear forensic experts that cooperate to deter the illicit trafficking of nuclear materials. The objective of the ITWG is to provide a common approach and effective technical solutions to governments who request assistance in nuclear forensics. The ITWG was chartered in 1996 and since that time more than 28 nations and organizations have participated in 9 international meetings and 2 analytical round-robin trials. Soon after its founding the ITWG adopted a general framework to guide nuclear forensics investigations that includes recommendations for nuclear crime scene security and analysis, the best application of radioanalytical methods, the conduct of traditional forensic analysis of contaminated materials, and effective data analysis to interpret the history of seized nuclear materials. This approach has been adopted by many nations as they respond to incidents of illicit nuclear trafficking

    In the not too distant future, the economy of nuclear power will have to be restudied. Various conditions and circumstances supporting this economy of nuclear power tend to change, such as the decrease in power demand and supply, the diversification in base load supply sources, etc. The fragility in the economic advantage of nuclear power may thus be revealed. In the above connection, on the basis of the future outlook of the scale of nuclear power generation, that is, the further reduction of the current nuclear power program, and of the corresponding supply and demand of nuclear fuel cycle quantities, the aspect of the economic advantage of nuclear power was examined, for the purpose of optimizing the future scale of nuclear power generation (the downward revision of the scale, the establishment of the schedule of nuclear fuel cycle the stagnation of power demand and nuclear power generation costs).

    To develop a brief and reliable psychometric scale to identify individuals at risk for suicidal behaviour. Case-control study. 182 individuals (61 suicide attempters, 57 psychiatric controls, and 64 psychiatrically healthy controls) aged 18 or older, admitted to the Emergency Department at Puerta de Hierro University Hospital in Madrid, Spain. All participants completed a form including their socio-demographic and clinical characteristics, and the Personality and Life Events scale (27 items). To assess Axis I diagnoses, all psychiatric patients (including suicide attempters) were administered the Mini International Neuropsychiatric Interview. Descriptive statistics were computed for the socio-demographic factors. Additionally, χ(2) independence tests were applied to evaluate differences in socio-demographic and clinical variables, and the Personality and Life Events scale between groups. A stepwise linear regression with backward variable selection was conducted to build the Short Personality Life Event (S-PLE) scale. In order to evaluate the accuracy, a ROC analysis was conducted. The internal reliability was assessed using Cronbach's α, and the external reliability was evaluated using a test-retest procedure. The S-PLE scale, composed of just 6 items, showed good performance in discriminating between medical controls, psychiatric controls and suicide attempters in an independent sample. For instance, the S-PLE scale discriminated between past suicide and past non-suicide attempters with sensitivity of 80% and specificity of 75%. The area under the ROC curve was 88%. A factor analysis extracted only one factor, revealing a single dimension of the S-PLE scale. Furthermore, the S-PLE scale provides values of internal and external reliability between poor (test-retest: 0.55) and acceptable (Cronbach's α: 0.65) ranges. Administration time is about one minute. The S-PLE scale is a useful and accurate instrument for estimating the risk of suicidal behaviour in

    2012-01-01

    Full Text Available The present paper deals with propeller ventilation in full scale. The paper is based on full scale monitoring data from an offshore supply ship during normal operation. The data was collected by the on-line monitoring system HeMoS, developed by Rolls Royce Marine. The data covering one year and a half of ship operations were made available within the framework of the Era-Net Martec project PropSeas. The ventilation events are identified by means of an analysis procedure based on fuzzy logic. The paper contains both a basic introduction to fuzzy logic and a detailed description of the analysis procedure. The analysis procedure is then adopted to process the available data, find ventilation events, and form a set which is further analyzed including weather observations.

    permitting process in the country as well as important planned (or recently introduced) changes in the relevant legislation. The analysis also presents the role of the regulating authorities as well as other key actors in the process, and outlines the different steps of the permitting processes, including the relationships between the different permits. We also address the responsibility for the radioactive waste and dismantling, and how these issues come into the licensing process. Important differences and similarities across the various countries are highlighted, with special emphasis on parallels to the Swedish legislation. The report then analyzes a number of important legal and political issues of a principal nature in the permitting of nuclear power plants. We compare how the different countries differ on these grounds, and also emphasize some overall lessons and practical experiences of nuclear power development internationally. Three broad issues are discussed. The first of these concerns the notion of nuclear power as a highly political issue, and we analyze the role of the public opinion, the extent to which the regulatory process is independent of policy decisions, as well as the allocation of political power between the national and local levels in the respective countries. Not the least the last issue has been in focus in some of the countries that have reformed their permitting process, and there exist significant inter-country differences. The second issue concerns how a number of countries - most notably the USA and Great Britain - have attempted to streamline their plant permitting processes for new nuclear power. These reforms are characterized by, for instance, a combined construction and operation license, the selection (and exclusion) of geographical locations for new installations, as well as attempts to achieve standardizations of nuclear reactor designs. We pay particular attention to the issues of reactor design standardization, including the scope

  1. Recovery operations in the event of a nuclear accident or radiological emergency

    International Nuclear Information System (INIS)

    1990-01-01

    Much progress has been made over the last decade in the field of emergency planning and preparedness, including the development of guidance, criteria, training programmes, regulations and comprehensive plans in the support of nuclear facilities. To provide a forum for international review and discussion of actual experiences gained and lessons learned from the different aspects of recovery techniques and operations in response to serious accidents at nuclear facilities and accidents associated with radioactive materials, the IAEA organized the International Symposium on Recovery Operations in the Event of a Nuclear Accident or Radiological Emergency. The symposium was held from 6 to 10 November 1989 in Vienna, Austria, and was attended by over 250 experts from 35 Member State and 7 international organizations. Although the prime focus was on on-site and off-site recovery from nuclear reactor accidents and on recovery from radiological accidents unrelated to nuclear power plants, development of emergency planning and preparedness resources was covered as well. From the experiences reported, lessons learned were identified. While further work remains to be done to improve concepts, plans, materials, communications and mechanisms to assemble quickly all the special resources needed in the event of an accident, there was general agreement that worldwide preparations to handle any possible future radiological emergencies had vastly improved. A special feature of the symposium programme was the inclusion of a full session on an accident involving a chemical explosion in a high level waste tank a a plutonium extraction plant in the Southern Urals in the USSR in 1957. Information was presented on the radioactive release, its dissemination and deposition, the resultant radiation situation, dose estimates, health effects follow-up, and the rehabilitation of contaminated land. This volume contains the full text of the 49 papers presented at the symposium together with a

    2014-01-01

    Nuclear Information Research Project of Institute of Nuclear Safety System, Incorporated (INSS) had acquired trouble information of nuclear power plants (NPPs) up to annual several thousand events issued by overseas regulatory agencies for more than 20 years since INSS established and analyzed it in details respectively after the screening. Lessons extracted from the analysis were offered as suggestions to electric utilities having PWRs in Japan. Such activities would surely contribute to maintain and improve nuclear safety with no objection. However, they could not prevent the occurrence of accident of Fukushima Daiichi NPPs. Thus the project had reviewed usefulness of past activities and how improved could be by listening sincerely to outside opinions. This report introduced outlines of recent activities. Competent suggestions to electric utilities might be made with improved reflection of lessons to needed rules, deepened information sharing within the project and raised awareness of the problem. (T.

  10. Protection of the Population in the event of a Nuclear accident. A Basis for Intervention

    International Nuclear Information System (INIS)

    1990-01-01

    During the years following the Chernobyl accident in 1986, the NEA actively participated in the international effort towards the improvement and better harmonization of the international and national criteria for the protection of the public in the event of a nuclear accident. A first report on this matter, titled Nuclear Accidents: Intervention Levels for Protection of the Public was published by the NEA in 1989. Subsequently, the NEA Committee on Radiation Protection and Public Health set up a small Task Group to provide additional guidance, and to take into account recent developments in other international organizations. The report outlines the status of relevant international activities in the period following the preparation of the 1989 report, discusses the intervention principles and describes both the proposed accident management system and a general scheme for its application. It is to be noted that the principles and criteria for intervention discussed in this report, although developed with specific reference to reactor accidents, apply equally well to activities and possible accidents at other nuclear facilities. The report briefly describes the transition from an accident management situation back to a normal situation and the related problem of changing criteria for the protection of the public. In addition to the traditional exposure pathways -inhalation from the cloud, external irradiation from the cloud and the ground and ingestion of food - the report acknowledges the existence of special pathways, proposing criteria for protecting workers and the public and some examples of their application

    As an international organization the American Nuclear Society (ANS) has played an active role in international co-operation of nuclear technology exchange since its establishment in 1954. The ANS has a membership of over 13,000 individuals, of whom approximately 1200 live overseas in forty countries. To carry out the goals of the Society, local sections have been established. Currently the ANS maintains 48 local sections in the United States of America and 8 overseas local sections in Africa, Asia, Europe and South America. The ANS also has formal agreements for co-operation with The Asociacion Argentina de Tecnologia Nuclear (AATN), the Israel Nuclear Society (INS), and the Chinese Nuclear Society (CNS). In 1977 the Japan Atomic Energy Society (JAES), the European Nuclear Society (ENS), and the ANS co-operation in sponsoring the First International Conference on Transfer of Nuclear Technology (ICONTT I) in Tehran, Iran. In 1982, the Second International Conference on Transfer of Nuclear Technology (ICONTT II), Buenos Aires, Argentina, was sponsored through the co-operation of the AATN, the ENS and the ANS. The ANS and its overseas sections sponsor the Pacific Basin Conference approximately every three years to discuss nuclear matters of concern to the countries around the Pacific Ocean. In 1981 the ANS held a Nuclear Technology Exhibit in Beijing, the People's Republic of China. In addition to meetings, the ANS is extensively involved in the co-operative exchange of applied nuclear research information through its publications. Nuclear Technology, a technical journal, is published monthly under joint ownership of the ENS and the ANS. The ANS has been a leader in voluntary standards development since 1958. In its dedication to the co-operation of international nuclear technology the ANS maintains a comprehensive international exchange of nuclear standards

  17. Opposition to nuclear power: a review of international experience

    Energy Technology Data Exchange (ETDEWEB)

    Surrey, J.; Huggett, C.

    1976-12-01

    This paper examines the rise of opposition to nuclear power in the USA, the Federal Republic of Germany, France, Sweden, and Japan. It explores the course that opposition has taken, the issues on which it has focused, the factors that have influenced it, and the problems it poses for public decision making. Opinions differ about the causes of nuclear opposition. Indeed, it is probable that a variety of factors have contributed, including cultural and political values regarding continued economic and energy growth and fears of deliberate large-scale violence with the spread of radioactive materials, the protest movements against nuclear weapons testing, the upsurge in environmental concern in the 1960s, the movement towards greater social responsibility in science, and a growing distrust of ''the Establishment''--particularly in the USA because of Watergate. The upsurge in concern was reflected in greater attention to environmental matters in the mass media, schools, universities, and the international agencies. It is important to recognize that this concern cuts across conventional left-right divisions of politics. Radicals, communists, and conservatives can be found among both the proponents and the critics. These difficulties facing the policy maker are accentuated by the amorphous nature both of the opposition and the issues which have received attention and by the evidence of many opinion surveys: that more people are in favor of nuclear power than oppose it, but the majority are uncertain and do not understand the issues. For purposes of analysis it is useful to distinguish between three types of opposition--nuclear-specific, site-specific, and that related to planning and consent procedures. (MCW)

    Simard, R.L.

    1983-01-01

    Two key systems essential to the gathering and dissemination of operating experience, the Nuclear Plant Reliability Data System (NPRDS) and NUCLEAR NOTEPAD are described. The NPRDS is a collection of detailed engineering data on systems and components important to nuclear plant safety and productivity. NUCLEAR NOTEPAD is an international telecommunications network which provides a mechanism for the rapid, widespread dissemination of information pertinent to the design, licensing, safe and reliable operation of nuclear plants. Both systems have been managed by the Institute of Nuclear Power Operations since 1982 and are used extensively by 84 organizations in 14 countries. (U.K.)

    2006-01-01

    This paper describes the operations and main activities of the International Nuclear Information System (INIS), which was established 35 years ago as the international mechanism for exchanging information in the fields of peaceful uses of nuclear sciences and technology. It outlines the system's main features, users and products. International cooperation and decentralisation are the distinguishing features of this system. INIS produces, maintains and preserves Member States knowledge in these fields. The system has been instrumental in supporting national nuclear programmes, and thousands of scientists, researchers and universities students are using INIS products to retrieve current and historical nuclear information.

    David, J.L.

    1988-01-01

    This study on the specificity of international nuclear trade law covers public international and private international aspects. As regards the first, international organisations and agreements (bilateral and multilateral) are reviewed. In the context of the second, the international organisations with a scientific, legal or commercial vocation are briefly listed. Commercial contracts are then studied in greater detail from the viewpoint of contractual nuclear liability and that outside the contracts. In addition, special aspects are examined, relating to the flexibility of supply contracts, swap agreements in the nuclear field, and other more particular clauses such as the ''Consensus'' framework for export credits. The authors' conclusion is that while there is no specificity properly speaking in international nuclear trade law, it nevertheless has original features (NEA) [fr

  3. Chapter two: Phenomenology of tsunamis II: scaling, event statistics, and inter-event triggering

    Science.gov (United States)

    Geist, Eric L.

    2012-01-01

    Observations related to tsunami catalogs are reviewed and described in a phenomenological framework. An examination of scaling relationships between earthquake size (as expressed by scalar seismic moment and mean slip) and tsunami size (as expressed by mean and maximum local run-up and maximum far-field amplitude) indicates that scaling is significant at the 95% confidence level, although there is uncertainty in how well earthquake size can predict tsunami size (R2 ~ 0.4-0.6). In examining tsunami event statistics, current methods used to estimate the size distribution of earthquakes and landslides and the inter-event time distribution of earthquakes are first reviewed. These methods are adapted to estimate the size and inter-event distribution of tsunamis at a particular recording station. Using a modified Pareto size distribution, the best-fit power-law exponents of tsunamis recorded at nine Pacific tide-gauge stations exhibit marked variation, in contrast to the approximately constant power-law exponent for inter-plate thrust earthquakes. With regard to the inter-event time distribution, significant temporal clustering of tsunami sources is demonstrated. For tsunami sources occurring in close proximity to other sources in both space and time, a physical triggering mechanism, such as static stress transfer, is a likely cause for the anomalous clustering. Mechanisms of earthquake-to-earthquake and earthquake-to-landslide triggering are reviewed. Finally, a modification of statistical branching models developed for earthquake triggering is introduced to describe triggering among tsunami sources.

    The closed environment of the International Space Station (ISS) creates an ideal environment for microbial growth. Previous studies have identified the ubiquitous nature of microorganisms throughout the space station environment. To ensure safety of the crew, microbial monitoring of air and surface within ISS began in December 2000 and continues to be monitored on a quarterly basis. Water monitoring began in 2009 when the potable water dispenser was installed on ISS. However, it is unknown if high microbial counts are associated with inflight medical events. The microbial counts are determined for the air, surface, and water samples collected during flight operations and samples are returned to the Microbiology laboratory at the Johnson Space Center for identification. Instances of microbial counts above the established microbial limit requirements were noted and compared inflight medical events (any non-injury event such as illness, rashes, etc.) that were reported during the same calendar-quarter. Data were analyzed using repeated measures logistic regression for the forty-one US astronauts flew on ISS between 2000 and 2012. In that time frame, instances of microbial counts being above established limits were found for 10 times for air samples, 22 times for surface samples and twice for water. Seventy-eight inflight medical events were reported among the astronauts. A three times greater risk of a medical event was found when microbial samples were found to be high (OR = 3.01; p =.007). Engineering controls, crew training, and strict microbial limits have been established to mitigate the crew medical events and environmental risks. Due to the timing issues of sampling and the samples return to earth, identification of particular microorganisms causing a particular inflight medical event is difficult. Further analyses are underway.

  5. Scaled biotic disruption during early Eocene global warming events

    Directory of Open Access Journals (Sweden)

    S. J. Gibbs

    2012-11-01

    Full Text Available Late Paleocene and early Eocene hyperthermals are transient warming events associated with massive perturbations of the global carbon cycle, and are considered partial analogues for current anthropogenic climate change. Because the magnitude of carbon release varied between the events, they are natural experiments ideal for exploring the relationship between carbon cycle perturbations, climate change and biotic response. Here we quantify marine biotic variability through three million years of the early Eocene that include five hyperthermals, utilizing a method that allows us to integrate the records of different plankton groups through scenarios ranging from background to major extinction events. Our long time-series calcareous nannoplankton record indicates a scaling of biotic disruption to climate change associated with the amount of carbon released during the various hyperthermals. Critically, only the three largest hyperthermals, the Paleocene–Eocene Thermal Maximum (PETM, Eocene Thermal Maximum 2 (ETM2 and the I1 event, show above-background variance, suggesting that the magnitude of carbon input and associated climate change needs to surpass a threshold value to cause significant biotic disruption.

    The major advantages of nuclear emulsion for detecting charged particles are its submicron position resolution and sensitivity to minimum ionizing particles. These must be balanced, however, against the difficult manual microscope measurement by skilled observers required for the analysis. We have developed an automated system to acquire and analyze the microscope images from emulsion chambers. Each emulsion plate is analyzed independently, allowing coincidence techniques to be used in order to reject background and estimate error rates. The system has been used to analyze a sample of high-multiplicity Pb-Pb interactions (charged particle multiplicities ∝ 1100) produced by the 158 GeV/c per nucleon 208 Pb beam at CERN. Automatically measured events agree with our best manual measurements on 97% of all the tracks. We describe the image analysis and track reconstruction techniques, and discuss the measurement and reconstruction uncertainties. (orig.)

  7. Hipse: an event generator for nuclear collisions at intermediate energies

    Energy Technology Data Exchange (ETDEWEB)

    Lacroix, D.; Van Lauwe, A.; Durand, D

    2003-11-01

    An event generator, HIPSE (Heavy-Ion Phase-Space Exploration), dedicated to the description of nuclear collisions in the intermediate energy range is presented. Based on the sudden approximation and on geometrical hypothesis, it can conveniently simulate heavy-ion interactions at all impact parameters and thus can constitute a valuable tool for the understanding of processes such as neck emission or multifragmentation in peripheral or/and central collisions. After a detailed description of the ingredients of the model, first comparisons with experimental data collected by the INDRA collaboration are shown. Special emphasis is put on the kinematical characteristics of fragments and light particles observed at all impact parameters for Xe+Sn reactions at 25 and 50 MeV/u and Ni + Ni at 82 MeV/u.

    2006-01-01

    The OECD Nuclear Energy Agency (Nea) has a long tradition of expertise in the area of nuclear emergency policy, preparedness, and management. The 1986 Chernobyl accident demonstrated that nuclear accidents may have consequences over wide areas, highlighting the need for international cooperation, coordination and communication. From the beginning, the Nea focus of work, as carried out by the Working Party on Nuclear Emergency Matters, has been on improving the effectiveness of international nuclear emergency preparedness and management. A major pillar of this work has been the preparation and organisation of the International Nuclear Emergency Exercise (I.N.E.X.) series. Beginning in 1993, the Nea I.N.E.X. series has proved successful in testing and developing arrangements for nuclear emergency response. The I.N.E.X.-1,-2 and -2000 series, which focussed on the early-phase of an emergency, provided a unique forum for testing existing as well as new arrangements and concepts for international nuclear emergency management, and succeeded in establishing a recognised international nuclear emergency exercise culture. In response to international interest in the longer term consequence management issues that will arise after an emergency, the Nea developed a third generation of exercises, I.N.E.X. 3. The I.N.E.X. 3 series of national level table-top exercises focused on the response to widespread radiological contamination of the environment and the issues likely to be raised in the medium to longer term period after such an event. Exercise objectives included an investigation of decisions on agricultural countermeasures and food restrictions, countermeasures such as travel and trade, recovery management and public information. The evaluation aimed to identify aspects of national decision-making which would benefit from international co-ordination, compare national approaches and identify 'best' practices in these circumstances.

  10. International technical working group cooperation to counter illicit nuclear trafficking

    International Nuclear Information System (INIS)

    Smith, D.K.

    2004-01-01

    Full text: The Nuclear Smuggling International Technical Working Group (ITWG) is an international group of nuclear forensic experts that cooperate to deter the illicit trafficking of nuclear materials. The objective of the ITWG is to provide a common approach and effective technical solutions to governments who request assistance in nuclear forensics. The ITWG was chartered in 1996 and since that time more than 28 nations and organizations have participated in 9 international meetings and 2 analytical round-robin trials. Soon after its founding the ITWG adopted a general framework to guide nuclear forensics investigations that includes recommendations for nuclear crime scene security and analysis, the best application of radioanalytical methods, the conduct of traditional forensic analysis of contaminated materials, and effective data analysis to interpret the history of seized nuclear materials. This approach has been adopted by many nations as they respond to incidents of illicit nuclear trafficking. ITWG members include policy and decision makers, law enforcement personnel, and scientists with expertise in, and responsibility for, nuclear forensics. It remains an association of active practitioners of nuclear forensics underwritten by funding from sponsoring countries and organizations. While the primary mission of the ITWG continues to be advancing the science and techniques of nuclear forensics and sharing technical and information resources to combat nuclear trafficking, recently the ITWG has focused on improvements to its organization and outreach. Central is the establishment of guidelines for best practices in nuclear forensics, conducting international exercises, promoting research and development, communicating with external organizations, providing a point-of-contact for nuclear forensics assistance, and providing mutual assistance in nuclear forensics investigations. By its very nature nuclear trafficking is a transboundary problem; nuclear materials

  11. The INES scale

    International Nuclear Information System (INIS)

    2014-01-01

    This document presents the International Nuclear Event Scale (INES) which has been created to classify nuclear and radiological events in terms of severity. This scale comprises eight levels from 0 to 7, from a slight but noticeable shift with respect to nominal operation to a major accident. Criteria used for incident and accident classification are indicated; they are based on consequences outside the site, consequences within the site, degradation of in-depth defence. The benefit and weaknesses of this scale are briefly indicated. The major concerned actors are the IAEA, the NEA and the ASN. Some key figures are given (number of declared events and incidents), and a ranking of the main nuclear events is proposed with a brief description of the event: Chernobyl, Fukushima, Kyshtym, Three Mile Island, Sellafield, Tokaimura, Saint-Laurent-des-Eaux. Countries which have adopted INES are indicated, as well as the number of incidents reports in France to the ASN

  12. Liability and insurance aspects of international transport of nuclear materials

    International Nuclear Information System (INIS)

    van Gijn, S.H.

    1985-01-01

    The Paris and Vienna Conventions do not affect the application of any international transport agreement already in force. However, in certain circumstances both the nuclear operator and the carrier may be held liable for nuclear damage which arises during international transports of nuclear materials. The ensuing cumulation of liabilities under the Nuclear and Transport Conventions may cause serious problems in obtaining adequate insurance cover for such transports. The 1971 Brussels Convention seeks to solve this problem by exonerating any person who might be held liable for nuclear damage under an international maritime convention or national law. Similar difficulties are encountered in the case of transports of nuclear materials between states which have and states which have not ratified the Paris and Vienna Conventions. (NEA) [fr

  13. International symposium on nuclear security. Book of extended synopses

    International Nuclear Information System (INIS)

    2009-01-01

    The International Symposium on Nuclear Security took place within a context of international acknowledgement that the threat of nuclear terrorism required dedicated action by the international community, States, industry and others. The Symposium dealt with those issues involved in protecting nuclear and other radioactive material from criminals. It also took place against a backdrop of renewed interest in nuclear technology: increased use of nuclear power, and increased use of radioactive isotopes in medicine and in industry. These are welcome developments, since nuclear energy and technology can indeed contribute to the technological and economic welfare of many countries, without compromising public health or the environment. In this context, security measures should not impede State programmes for peaceful use of nuclear technology. The symposium dealt with (1) the threat of nuclear terrorism and of other nuclear-related criminal acts; (2) international response and cooperation; (3) safety, security and safeguards; (4) securing material and facilities; (5) unregistered and uncontrolled radioactive substances; (6) information sharing; (7) role of industry and (8) IAEA nuclear security programme.

    BRAUNEGGER-GUELICH, A.; RUKHLO, V.; GREGORIC, M.; COLGAN, P.

    2011-01-01

    The threat of nuclear terrorism has not diminished. In response to the concerns of States, an international nuclear security framework has emerged through the establishment of a number of legally binding and non-binding international instruments which obligates or commits States to carry out a number of actions to protect against nuclear terrorism. In this context, the need for human resource development programmes in nuclear security was underscored at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors' Meetings. In the pursuit of this need, the IAEA provides a comprehensive nuclear security training programme to States on a regular basis, and has developed a concept that seeks to effectively pass ownership of nuclear security knowledge and skills to States through the establishment of a Nuclear Security Support Centre. In addition, the IAEA has developed a technical guidance titled IAEA Nuclear Security Series No. 12 - Educational Programme in Nuclear Security that consists of a model of a Master of Science (M.Sc.) and assists educational institutions to provide nuclear security education. The article sets out IAEA efforts in the area of nuclear security training and education, including the assistance to States for establishing a Nuclear Security Support Centre. It underlines the objective and content of the IAEA Nuclear Security Series No. 12, discusses different concepts on how to establish nuclear security at universities and, emphasizes on the IAEA efforts to assist educational and research institutions, and other stake holders to enhance global nuclear security by developing, sharing and promoting excellence in nuclear security education.

    D'Auria, F.; Galassi, G.M.

    2010-01-01

    Scaling is a reference 'key-word' in engineering and in physics. The relevance of scaling in the water cooled nuclear reactor technology constitutes the motivation for the present paper. The origin of the scaling-issue, i.e. the impossibility to get access to measured data in case of accident in nuclear reactors, is discussed at first. The so-called 'scaling-controversy' constitutes an outcome. Then, a critical survey (or 'scaling state-of-art';) is given of the attempts and of the approaches to provide a solution to the scaling-issue in the area of Nuclear Reactor System Thermal-Hydraulics (NRSTH): dimensionless design factors for Integral Test Facilities (ITF) are distinguished from scaling factors. The last part of the paper has a two-fold nature: (a) classifying the information about achievements in the area of thermal-hydraulics which are relevant to scaling: the concepts of 'scaling-pyramid' and the related 'scaling bridges' are introduced; (b) establishing a logical path across the scaling achievements (represented as a 'scaling puzzle'). In this context, the 'roadmap for scaling' is proposed: the objective is addressing the scaling issue when demonstrating the applicability of system codes in the licensing process of nuclear power plants. The code itself is referred hereafter as the 'key-to-scaling'. The database from the operation of properly scaled ITF and the availability of qualified system codes are identified as main achievements in NRSTH connected with scaling. The 'roadmap to scaling' constitutes a unified approach to scaling which aims at solving the 'scaling puzzle' created by researches performed during a half-a-century period.

  19. Outlook of nuclear power generation and international situation

    International Nuclear Information System (INIS)

    Eklund, S.

    1978-01-01

    Nuclear power generation is advancing at rapid rate over the world, without any major accident. For the base load of electric power, when choice is made between nuclear energy and petroleum, the Nuclear energy has larger economic advantages over the petroleum as compared with the days before the oil crisis. The costs of its fuel and fuel cycle technology are reasonble. However, nuclear power generation currently has a number of problems. What causes this uncertainty is not technological, but political, i.e. governmental policy changes, and this is based on the apprehension about nuclear proliferation. What is necessary is to strengthen the existing international framework of nuclear nonproliferation. In this respect, IAEA through comprehensive safeguards will make contribution largely to reduction of the political uncertainty. It is important that the new initiatives toward international nuclear cooperation should eliminate the current trends of restraint and denial. (Mori, K.)

    Probabilistic risk assessment of nuclear power plants initially focused on events initiated by internal faults at the plant, rather than external hazards including earthquakes and flooding. Although the importance of external hazards risk analysis is now well recognized, the methods for analyzing low probability external hazards rely heavily on subjective judgment of specialists, often resulting in substantial conservatism. This research developed a framework to integrate the risk of seismic and flooding events using realistic structural models and simulation of response of nuclear structures. The results of four application case studies are presented.

    In their regulations, the U.S. Environmental Protection Agency and the U.S. Nuclear Regulatory Commission permit the omission of features, events, or processes with probabilities of repository at Yucca Mountain for radioactive waste is one disruptive event that has a probability with a range of uncertainty that straddles this regulatory criterion and is considered directly in performance assessment calculations. A self-sustained nuclear chain reaction (or "criticality") is another potentially disruptive event to consider, although it was never found to be important when evaluating the efficacy of radioactive waste disposal since the early 1970s. The thesis of this article is that the consideration of the joint event--volcanism and criticality--occurring in any 10,000-year period following closure can be eliminated from performance calculations at Yucca Mountain. The probability of the joint event must be less than the fairly well-accepted but low probability of volcanism. Furthermore, volcanism does not "remove" or "fail" existing hydrologic or geochemical constraints at Yucca Mountain that tend to prevent concentration of fissile material. Prior to general corrosion failure of waste packages, the mean release of fissile mass caused by a low-probability, igneous intrusive event is so small that the probability of a critical event is remote, even for highly enriched spent nuclear fuel owned by the U.S. Department of Energy. After widespread failure of packages occurs, the probability of the joint event is less than the probability of criticality because of the very small influence of volcanism on the mean fissile mass release. Hence, volcanism plays an insignificant role in inducing criticality over any 10(4)-yr period. We also argue that the Oklo reactors serve as a natural analogue and provide a rough bound on probability of criticality given favorable hydrologic or geochemical conditions on the scale of the repository that is less than 0.10.

    As there is increasing use of nuclear energy and radiation while information on nuclear related accidents are accumulated, international interest in nuclear and radiation incidents is increasing rapidly. Because of the specificity of nuclear energy and radiation, the damage caused by such accidents will be spread to the larger area around the accident point due to the radiation and cause biological damage and mental-psychological damage. The purpose of this study is to categorize historical incidents using the Threat Category concept described in the publication of IAEA Safety Guide GS-G-2.1. In addition to categorizing actual events and accidents into Threat Categories, causes of occurrences, the type of radioactive source which leads to the main threats, the type of radiation exposure, and the type of patient are organized in detail. As a result of the analysis of representative historical cases, most accident cases caused by 'Nuclear Energy-Related Business Operator' correspond to 1 (Anomaly) ~ 4 (Accident with Local Consequences) in the INES Scale by IAEA. From the some accident cases, while the radiological damage can be seen to be local, but it can be seen that the possibility of 6 (Serious Accident) can not be absolutely excluded.

    In cooperation with the OECD Nuclear Energy Agency (NEA), the Halden Reactor Project organised a Summer School on nuclear fuel in the period August 28 September 1, 2000. The summer school was primarily intended for people who wanted to become acquainted with fuel-related subjects and issues without being experts. It was especially hoped that the summer school would serve to transfer knowledge to the ''young generation'' in the field of nuclear fuel. Experts from Halden Project member organisations gave the following presentations: (1) Overview of the nuclear community, (2) Criteria for safe operation and design of nuclear fuel, (3) Fuel design and fabrication, (4) Cladding Manufacturing, (5) Overview of the Halden Reactor Project, (6) Fuel performance evaluation and modelling, (7) Fission gas release, and (8) Cladding issues. Except for the Overview, which is a written paper, the other contributions are overhead figures from spoken lectures.

  8. The international framework for safeguarding peaceful nuclear energy programs

    Mazer, B.M.

    1980-01-01

    International law, in response to the need for safeguard assurances, has provided a framework which can be utilized by supplier and recipient states. Multilateral treaties have created the International Atomic Energy Agency which can serve a vital role in the establishment and supervision of safeguard agreements for nuclear energy programs. The Non-Proliferation Treaty has created definite obligations on nuclear-weapon and non-nuclear weapon states to alleviate some possibilities of proliferation and has rejuvenated the function of the IAEA in providing safeguards, especially to non-nuclear-weapon states which are parties to the Non-Proliferation treaty. States which are not parties to the Non-Proliferation Treaty may receive nuclear energy co-operation subject to IAEA safeguards. States like Canada, have insisted through the bilateral nuclear energy co-operation agreements that either individual or joint agreement be reached with the IAEA for the application of safeguards. Trilateral treaties among Canada, the recipient state and the IAEA have been employed and can provide the necessary assurances against the diversion of peaceful nuclear energy programs to military or non-peaceful uses. The advent of the Nuclear Suppliers Group and its guidlines has definitely advanced the cause of ensuring peaceful uses of nuclear energy. The ultimate objective should be the creation of an international structure incorporating the application of the most comprehensive safeguards which will be applied universally to all nuclear energy programs

    The growing importance of nuclear energy (on the threshold of the twenty-first century) and of its ethical uses is considered, including major political events in recent years, their social and economic consequences in the world scene. International Nuclear Law is seen as the most adequate instrument to promote the ethical uses of nuclear energy on a worldwide basis, so that mankind can benefit safely and properly and improving their living conditions in general. Problems associated with access to nuclear technology, plants, equipments and materials are addressed. Basic principles of international agreements ruling nuclear trade, ethical aspects are also covered. The different markets involved in international nuclear trade and their specific requirements are described. Certain international treaties on the peaceful uses of nuclear energy are discussed such as the Non-Proliferation Treaty and the Tlatelolco Treaty as are international conventions on matters related to the use of nuclear energy, such as the environment and protection of personnel. The author concludes by debating whether ethical uses of nuclear energy are a possible reality or merely utopia. Prospects on the future of international nuclear trade are considered. (author)

    We can expect to see the peak of world oil production very soon. Some say that we can see that peak now in our rear-view mirrors as we drive into an oil-poor future. Natural gas already is in short supply in North America. Nuclear energy must make up the lion's share of the world's energy deficit. This paper examines, in very general terms, the implications of today's shifting prospects for nuclear energy, as it exists today, and how those prospects might develop in the future. The time span under consideration is the remainder of the 21st century. (author)

  11. Individualized adjustments to reference phantom internal organ dosimetry - scaling factors given knowledge of patient internal anatomy.

    Various computational tools are currently available that facilitate patient organ dosimetry in diagnostic nuclear medicine, yet they are typically restricted to reporting organ doses to ICRP-defined reference phantoms. The present study, while remaining computational phantom based, provides straightforward tools to adjust reference phantom organ dose for both internal photon and electron sources. A wide variety of monoenergetic specific absorbed fractions (SAFs) were computed using radiation transport simulations for tissue spheres of varying size and separation distance. Scaling methods were then constructed for both photon and electron self-dose and cross-dose, with data validation provided from patient-specific voxel phantom simulations, as well via comparison to the scaling methodology given in MIRD Pamphlet No. 11. Photon and electron self-dose was found to be dependent on both radiation energy and sphere size. Photon cross-dose was found to be mostly independent of sphere size. Electron cross-dose was found to be dependent on sphere size when the spheres were in close proximity, owing to differences in electron range. The validation studies showed that this dataset was more effective than the MIRD 11 method at predicting patient-specific photon doses for at both high and low energies, but gave similar results at photon energies between 100 keV and 1 MeV. The MIRD 11 method for electron self-dose scaling was accurate for lower energies but began to break down at higher energies. The photon cross-dose scaling methodology developed in this study showed gains in accuracy of up to 9% for actual patient studies, and the electron cross-dose scaling methodology showed gains in accuracy up to 9% as well when only the bremsstrahlung component of the cross-dose was scaled. These dose scaling methods are readily available for incorporation into internal dosimetry software for diagnostic phantom-based organ dosimetry. © 2018 Institute of Physics and Engineering in

  12. Effectiveness of Existing International Nuclear Liability Regime

    The first convention was the Paris Convention on Third Party Liability in the Field of Nuclear Energy (the Paris Convention) had been adopted on 29 July 1960 under the auspices of the OECD, and entered into force on 1 April 1968. In 1963,the Brussels Convention - supplementary to the Paris Convention- was adopted in to provide additional funds to compensate damage as a result of a nuclear incident where Paris Convention funds proved to be insufficient. The IAEA's first convention was the Vienna Convention on Civil Liability for Nuclear Damage (the Vienna Convention) which adopted on 21 May 1963,and entered into force in 1977. Both the Paris Convention and the Vienna Convention laid down very similar nuclear liability rules based on the same general principles. The broad principles in these conventions can be summarized as follows: 1- The no-fault liability principle (strict liability) 2- Liability is channeled exclusively to the operator of the nuclear installation (legal channeling) 3- Only courts of the state in which the nuclear accident occurs would have jurisdiction (exclusive jurisdiction) 4- Limitation of the amount of liability and the time frame for claiming damages (limited liability) 5- The operator is required to have adequate insurance or financial guarantees to the extent of its liability amount (liability must be financially secured). 6- Liability is limited in time. Compensation rights are extinguished after specific time. 7- Non-discrimination of victims on the grounds of nationality, domicile or residence. Nuclear liability conventions objective is to provide adequate compensation payments to victims of a nuclear accident. Procedures for receiving these compensation are controlled by some rules such as exclusive jurisdiction, that rule need a further amendment to ensure the effectiveness of the exiting nuclear liability regime . Membership of the Conventions is a critical issue, because the existence of the conventions without being party to

    The author gives a brief survey on the short, but relatively successful story of nuclear energy in the Federal Republic of Germany (FRG). Like many other countries, FRG had to go through a very difficult period of political indecision and violent opposition from antinuclear groups, supported by large parts of the media. The licensing procedures have been streamlined, nuclear power plants are being built without major interference, and the FRG is making good progress in closing the fuel cycle. This means that nuclear power will play an important role in the energy supply system, although on a lower level than originally anticipated

  14. International legal and political issues associated with the export/import of nuclear power plants

    1978-01-01

    The benefits of nuclear power can be achieved by most nations only through international commerce that has been shaped by political considerations and implemented through legal instruments. The end product is a structure of legal agreements designed to implement the basic political and commercial decisions that are required for any nation to enter the nuclear power arena. The IAEA Statute, the Non-Proliferation Treaty and regional nuclear agreements have reflected the international political consensus concerning nuclear power. In recent years, however, events have occurred that in all probability will result in additional international arrangements. It is expected that the increase in terrorist activities will result in greater physical protection commitments, that concern for weapons proliferation will result in further definition of sanctions, and that such troublesome issues as double labelling of materials will be discussed by the international community. In areas such as bilateral agreements between nations, commercial arrangements and export licences, this is a period of rethinking, renegotiating, and readjusting. The result is a degree of uncertainty and lack of stability that could so jeopardize the potential for nuclear transfers that the nuclear energy option may not vest. While there always will be questions and issues, it is essential to settle some of the key problems without delay so that nuclear benefits can be realized. (author)

  15. Guide on a national system for collecting, assessing and disseminating information on safety-related events in nuclear power plants

    International Nuclear Information System (INIS)

    1983-02-01

    There is a wide spectrum of safety significance in the events that can occur during nuclear power plant operations. It is important that lessons be learned from safety-related events (hereinafter referred to as unusual events) so as to improve the safety of nuclear power plants. Hence formal procedures should be established for this purpose. The purpose of this document is to provide guidance to Member States for establishing a system (hereinafter referred to as a national system) for collecting, storing, retrieving, assessing and disseminating information on unusual events in nuclear power plants. The guidance given is based on experience gained in the use of existing national and international systems. This guide covers a national system that is part of a programme to improve nuclear power plant safety using experience gained from operating plants both within and outside the country. Implementing the recommendations in this guide would render any national system compatible with other national systems and facilitate the participation in the IAEA System for Reporting Unusual Events with Safety Significance (hereinafter referred to as the IAEA Incident Reporting System, IAEA-IRS) for more widespread dissemination of lessons learned from nuclear power plant operation

    A title that critically reviews the decommissioning and decontamination processes and technologies available for rehabilitating sites used for nuclear power generation and civilian nuclear facilities, from fundamental issues and best practices, to procedures and technology, and onto decommissioning and decontamination case studies.$bOnce a nuclear installation has reached the end of its safe and economical operational lifetime, the need for its decommissioning arises. Different strategies can be employed for nuclear decommissioning, based on the evaluation of particular hazards and their attendant risks, as well as on the analysis of costs of clean-up and waste management. This allows for decommissioning either soon after permanent shutdown, or perhaps a long time later, the latter course allowing for radioactivity levels to drop in any activated or contaminated components. It is crucial for clear processes and best practices to be applied in decommissioning such installations and sites, particular where any ...

    Full text: This paper will present an overview of the current training the author is presenting to First Responders (fire-fighters, emergency medical technicians, law enforcement and others) who may encounter either a Radiological Dispersal Device (RDD or Dirty Bomb) or an Improvised Nuclear Device (IND) as a part of their Emergency Response activities. The emphasis of the training is putting the radiological/nuclear material in perspective as compared with other Weapons of Mass Destruction (WMD) materials such as chemical and/or biological weapon agents. A goal of the training is to help this First Responder Community understand that under almost all conditions, they can perform their primary mission of 'putting out fires', rescuing and treating injured persons, and chasing 'bad guys' even in the presence of relatively large amount of radiological/nuclear contamination. The rare cases of high activity unshielded sources will be reviewed and explained. Current International guidance on dose 'limits' will be discussed. A discussion of the use of Time, Distance and Shielding as well as appropriate Personal Protective Clothing and how it will provide the needed protection while immediate actions take place early in an RDD/IND event, will take place. The use of appropriate radiation detection instrumentation, documented Standard Operating Procedures along with realistic training, drills and exercises are the key to a successful response to an RDD/IND event for this community of critical emergency responders.

    Nuclear power generation is now sluggish from economical reason or sometimes together from political reason, except some exceptions in Western Europe, and U.S.A. It tends now to keep its present state or to decrease gradually as cannot say to be out of nuclear power generation. At these areas, anxiety on energy security becomes lower at present, and economics under liberation of market is preceded to everything because of without anxiety on environmental theory at a viewpoint of the global warming protection, either. However, when considering on finiteness of fossil fuel and long-term countermeasure of the global warming protection, no longer that any break-through on energy technology will form in future, it seems to occur that nuclear power would be re-recognized. For the Renaissance of the nuclear power, it is essential to correspond to some problems shown as follows: processing and disposal of high level radioactive wastes, upgrading of economics containing its initial cost, safe operation, maintenance of scientific technology standard on nuclear power, and nuclear non-scattering. And, on the energy problem, it is essential to recognize that Japan is a nation with a number of differences in its circumstance from those in U.S.A. and European nations. (G.K.)

    The city of Salzburg, on the banks of the Salzach River, is dominated by the Hohensalzburg Castle, the fortress of the Archbishops that ruled the region. The Old Town is architecturally of a single style, the baroque. Its picturesque streets with their wrought iron signs and the spacious squares with sculptured fountains have charmed countless visitors. Salzburg is also a popular site for international meetings. The Festspielhaus and the Kongresshaus will be the venue of the International Conference on Nuclear Power and Its Fuel Cycle. Some 2000 participants are expected to attend and 348 papers are scheduled for this major conference sponsored by the International Atomic Energy Agency. The Plenary Sessions will be held in the auditorium of the Festspielhaus, and the technical sessions and round-table discussions in the Kongresshaus. The Conference will open on 2 May with the first of five plenary sessions on world energy supply and demand and the future of nuclear power. Other topics to be covered include: supply of nuclear fuel and fuel cycle services, radioactivity management, nuclear safety, nuclear power and public opinion, safeguarding of nuclear materials, and nuclear power prospects in developing countries. Eight round-table discussions will take place during the Conference. These discussions will centre on the role of nuclear power in future energy supply, transfer of nuclear technology to developing countries, management of radioactivity and radioactive wastes, standardized safety reviews of exported nuclear power plants, and the need for integrated nuclear fuel cycle planning at the national and international levels. Special evening lectures by eminent nuclear scientists are also being planned. In addition, tours and group excursions for those attending the Conference are being organized. The Proceedings of the Conference will be published in eight volumes by the IAEA. (author)

    Since the beginning of the nuclear age in the 1940's, the world has focused on the immense possibilities of nuclear power with both its destructive and productive capabilities. The civil nuclear industry in the UK, as in most nuclear weapons states, grew from the military facilities built in the post war years under the political climate of the Cold War. In the early years of the industry, civil and defence nuclear facilities were inextricably linked both in public perceptions and the regulatory infrastructure under which they operated. The nuclear arms race and the spread of communism overshadowed people's perceptions of there being two separate uses of nuclear material. This was a double edged sword which initially allowed the industry to develop largely unhindered by public concerns but latterly meant the industry could not break away from its roots and to many is still perceived as a dangerous and destructive force. Regulatory frameworks governing all aspects of the industry have developed both nationally and internationally driven by valid public concerns, political agendas and an international consensus that the unregulated use of nuclear material has catastrophic possibilities on an international scale. With the internationalisation of the civil nuclear industry and the costs associated with developing facilities to fully support each stage of the fuel cycle, from enrichment, fuel manufacturing, reprocessing and waste remediation, it became inevitable that a transport infrastructure would develop to make best use of the facilities. Regulations, both national and international are implicit in ensuring the security of nuclear material in transit. Due to the physical size of many of the irradiated fuel packages and implications of the changes to transport safety regulations, international transports of nuclear material, other than within mainland Europe, is predominantly carried out by sea.

    Nuclear Malaysia is mandated by the Government of Malaysia, inter alia, to spearhead Research and Development (R&D) in nuclear and related technology. Technically, nuclear technology is a highly specialised subject in which expertise are thinly spread over the globe with concentration in mainly developed countries. Nuclear technology also tends to be politically sensitive and handling of radioactive materials and equipment needs high level of skills and knowledge for the safe and secured uses of this technology and needs to be regulated. Hence international cooperation and multilateral approach is of vital importance for the development and sustainability of peaceful uses of nuclear technology and to provide assurance that the interests of all parties are safeguarded and remains in check. In this context, the International Atomic Energy Agency or the IAEA, a UN agency, plays a vital role where international cooperation in nuclear technologies is centred. Malaysia also contributed a fair amount of financial resources to the IAEA as part of its international obligations to keep the Agency afloat. This paper provides an insight into various services and facilities offered or available at the IAEA in which researchers in Nuclear Malaysia could utilize in order to expand and enhance their R&D activities in nuclear and related technologies, as mandated by the Government of Malaysia, as well as ensuring that the investments will provide good returns in terms of socio-economic benefits, both tangible and intangible.

    It should be explained more to the outside modestly the Fukushima nuclear accident would be a man-made complex disaster, which might be reluctant to do but not be neglected. Utmost efforts to change inward-looking attitude and reform safety culture should be done so as to prevent superficial reflection of the Fukushima nuclear accident. Since all nuclear regulatory functions ('3S': safety, security, safeguards) were integrated in Nuclear Regulation Authority (NRA), NRA and secretariat of NRA became more responsible for international response, and strengthening of organization system and human resources development would be an urgent necessity. This article described present stage of NRA focusing on international dimension including personal views. Overseas strong concern over the Fukushima nuclear accident and international communications were reviewed. The Fukushima nuclear accident started from natural disaster and enlarged as a man-made complex disaster with many human factors (mainly inaction, wilful negligence) overlapping and safety culture flawed. Examples of overseas and Japanese action plan to learn and absorb lessons from the Fukushima accident were introduced. NRA's started activities on inviting IAEA's IRRS and OPPAS as soon as ready, strengthening nuclear security measures, safeguards to prevent nuclear proliferation, bilateral cooperation and international advisors were also presented.

    2017-01-01

    Over the course of more than seven decades, treaty norms on the production and utilisation of nuclear energy have been developed, which together form a special section within international law. These norms are the consequence of the unique nature of the field, namely that on the one hand some aspects of the uses of nuclear energy should be covered by totally new and special norms (e.g. in the field of disarmament, seeking to eliminate or at least to control the spread of nuclear weapons, and nuclear weapons tests) and on the other hand that several traditional legal solutions were not suitable for the problems that emerged in connection with other uses of nuclear energy (like liability). In this article, three aspects of the development of that special section of international law will be explored, namely: the close connections between the regulation of peaceful and military uses of nuclear energy; the effects of nuclear catastrophes on the development of international nuclear legislation; and the interaction between soft law norms and binding norms in the area of nuclear law

    The Nuclear Smuggling International Technical Working Group (ITWG) is an international group of nuclear forensic experts that cooperate to deter the illicit trafficking of nuclear materials. The objective of the ITWG is to provide a common approach and effective technical solutions to governments who request assistance in nuclear forensics. The ITWG was chartered in 1996 and since that time more than 28 nations and organizations have participated in 9 international meetings and 2 analytical round-robin trials. Soon after its founding the ITWG adopted a general framework to guide nuclear forensics investigations that includes recommendations for nuclear crime scene security and analysis, the best application of radioanalytical methods, the conduct of traditional forensic analysis of contaminated materials, and effective data analysis to interpret the history of seized nuclear materials.

ITWG members include policy and decision makers, law enforcement personnel, and scientists with expertise in, and responsibility for, nuclear forensics. (author)

  11. Notifiable events in systems for fission of nuclear fuels - nuclear power plants and research reactors with maximum output exceeding 50 kW of thermal normal rating - in the Federal Republic of Germany. Quarterly report, 2nd quarter of 1996

    International Nuclear Information System (INIS)

    1996-01-01

    There were 32 notifiable events in nuclear power plants in Germany in the second quarter of 1996. The report lists and characterises all the 32 events notified in the reporting period. The events did not involve any radioactivity release exceeding the maximum permissible limits during this period, so that there were no radiation hazards to the population or the environment. One event was classified at level 1 of the INES event scale (Anomaly). Research reactor operators in Germany reported 5 notifiable events in the reporting period. The report lists and characterises these events. These events did not involve any radioactivity release exceeding the maximum permissible limits during this period, so that there were no radiation hazards to the population or the environment. All events notified were classified into the lowest categories of safety significance of the official event scales (N, or below scale). (orig./DG) [de

    2002-01-01

    Steps necessary to be taken to ensure safety in nuclear installations are suggested. One of the steps suggested is enhancing the safety culture. It is necessary to gain a common understanding of the concept itself, the development stages of safety culture by way of good management practices and leadership for safety culture improvement in the long-term. International topical meetings on safety culture may serve as an important forum for exchange of experiences. From such conventions new initiatives and programmes may crop up which when implemented around the world is very likely to improve safety management and thus boost up the safety culture in nuclear installations. International co-operation and learning are to be prompted to facilitate the sharing of the achievements to face the challenges involved in the management of safety and fixing priorities for future work and identify areas of co-operations. Key lessons learned from some major events have been reported. Present status and future trend of nuclear safety culture in Bangladesh have been dealt with. (author)

    China's exporting behaviour of nuclear items had been disconnected from the international non-proliferation regime such as IAEA safeguards and export control related with peaceful use of nuclear energy since 1970s. Especially, China had been one of principle suppliers of nuclear facility and technologies to Pakistan and Iran which had developed nuclear weapon programs. On the other hand, according to the rapid growth of economic scale after China began to open to the world, an active program for nuclear power plant as an electricity source had established. This means that China have surfaced as a big market to Korean nuclear industries. Regarding this, the paper dealt with the nuclear export control matters, i.e. the history of nuclear export control system and analyzed on background of enforcement of U.S.-China Nuclear Cooperation Agreement that had been apolitical issue between U.S. and China. Prospects toward conforming its nuclear export policies, laws and regulations to international standards also analyzed in results

  16. Prospects for nuclear power international after Fukushima

    International Nuclear Information System (INIS)

    Kidd, Steve

    2012-01-01

    Full-text: The Fukushima accident in March 2011 has imposed a number of significant challenges for the world nuclear industry, in terms of enhancing safety at both existing and prospective reactor sites and in regaining public trust for its operations. Yet despite setbacks in a number of countries (notably Germany in addition to Japan itself) the overall outlook for nuclear power around the world is little changed from before the accident. The front end of the nuclear fuel cycle is fully internationalised and operates as a series of competitive markets, guaranteeing economic supply to the operating reactors around the world. Although new reactor types with potentially different fuelling modes are on the horizon, nothing much is likely to change before 2030. The back end is, however, comparatively less developed and there remain substantial uncertainties how it will develop in the future. Technical solutions exist, but governments have failed to grasp realities in used fuel management and waste disposal. Although many commentators argue that low levels of public acceptance are the prime reason for nuclear power failing to take a more substantial part of the energy mix, the root cause is relatively poor economics (at least in much of the Western world). Plants cost too much to build, essentially taking too long to complete, by comparison with rival generating technologies. Additionally, cheap natural gas has become a barrier in certain markets. The risk profile of nuclear projects therefore makes it difficult to attract financing but there are some possible solutions to these issues. (author)

  17. Reynolds number scaling of pocket events in the viscous sublayer

    Metzger, M.; Fershtut, A.; Kunkel, C.; Klewicki, J.

    2017-12-01

    Recent findings [X. Wu et al., Proc. Natl. Acad. Sci. USA 114, E5292 (2017), 10.1073/pnas.1704671114] reinforce earlier assertions [e.g., R. Falco, Philos. Trans. R. Soc. London A 336, 103 (1991), 10.1098/rsta.1991.0069] that the sublayer pocket motions play a distinctly important role in near-wall dynamics. In the present study, smoke visualization and axial velocity measurements are combined in order to establish the scaling behavior of pocket events in the viscous sublayer of the turbulent boundary layer. In doing so, an identical analysis methodology is employed over an extensive range of friction Reynolds numbers 388 ≤δ+≤2.2 ×105 . Both the pocket width W and time interval between pocket events T increase logarithmically with Reynolds number when normalized by viscous units. Normalization of W and T by the Taylor microscales evaluated at a wall-normal location of about 100 viscous units, however, appears to successfully remove this Reynolds-number dependence. The present results are discussed in the context of motion formation owing to the three dimensionalization of the near-wall vorticity field and, concomitantly, the recurring perturbation of the viscous sublayer.

    This chapter aims at discussing the objectives, implementation and integration of multi-scale modelling approaches applied to nuclear fuel materials. We will first show why the multi-scale modelling approach is required, due to the nature of the materials and by the phenomena involved under irradiation. We will then present the multiple facets of multi-scale modelling approach, while giving some recommendations with regard to its application. We will also show that multi-scale modelling must be coupled with appropriate multi-scale experiments and characterisation. Finally, we will demonstrate how multi-scale modelling can contribute to solving technology issues. (authors)

  20. Relative Time-scale for Channeling Events Within Chaotic Terrains, Margaritifer Sinus, Mars

    Janke, D.

    1985-01-01

    A relative time scale for ordering channel and chaos forming events was constructed for areas within the Margaritifer Sinus region of Mars. Transection and superposition relationships of channels, chaotic terrain, and the surfaces surrounding them were used to create the relative time scale; crater density studies were not used. Channels and chaos in contact with one another were treated as systems. These systems were in turn treated both separately (in order to understand internal relationships) and as members of the suite of Martian erosional forms (in order to produce a combined, master time scale). Channeling events associated with chaotic terrain development occurred over an extended geomorphic period. The channels can be divided into three convenient groups: those that pre-date intercrater plains development post-plains, pre-chasma systems; and those associated with the development of the Vallis Marineris chasmata. No correlations with cyclic climatic changes, major geologic events in other regions on Mars, or triggering phenomena (for example, specific impact events) were found.

  5. International status and prospects of nuclear power

    International Nuclear Information System (INIS)

    2008-12-01

    Nuclear power plants are primarily used for electricity production. Currently, 439 reactors are operating in 30 countries and are contributing approximately 14% to global electricity generation. The share of nuclear in global electricity generation has declined slightly in recent years. However, the total amount of nuclear electricity generation is increasing as plant availability, power uprating, and new plants offset the loss from older plants that are being shut down. Due to the economic benefits of continuing operation of a plant after the capital cost has been repaid, and with careful plant life management assessments, a number of reactors have had their operating licences extended for an additional 20 years. Light water reactors (LWRs) are by far the most prevalent reactors in use today, followed by pressurized heavy water reactors, gas cooled reactors and, currently, two fast reactors. The safety and reliability of nuclear facilities have been steadily improving. Strong networks among countries with operating nuclear power plants have enabled operators to learn from each other and to address common issues. Ongoing efforts have continuously strengthened safety culture and regulatory oversight. The current available supply of uranium meets the demand. Current enrichment and fuel fabrication capacities are adequate to meet the expected demand for the next decade. There is also substantial experience in the storage and reprocessing of spent fuel and the treatment of high level waste. Existing reprocessing capacity is adequate to meet present demand. Most spent fuel continues, however, to be stored awaiting a decision on future policy, i.e. whether to reprocess and recycle it or to dispose of it as waste. To date, no ultimate disposal facilities are available. Only a few countries currently use civil nuclear energy for purposes other than electricity production - mainly for seawater desalination and district heating - and even then only to a limited extent

    The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on angular scales comparable to that of the general relativistic shadow. Previous EHT observations have used visibility amplitudes to infer the morphology of the millimeter-wavelength emission. Potentially much richer source information is contained in the phases. We report on 1.3 mm phase information on Sgr A* obtained with the EHT on a total of 13 observing nights over four years. Closure phases, which are the sum of visibility phases along a closed triangle of interferometer baselines, are used because they are robust against phase corruptions introduced by instrumentation and the rapidly variable atmosphere. The median closure phase on a triangle including telescopes in California, Hawaii, and Arizona is nonzero. This result conclusively demonstrates that the millimeter emission is asymmetric on scales of a few Schwarzschild radii and can be used to break 180° rotational ambiguities inherent from amplitude data alone. The stability of the sign of the closure phase over most observing nights indicates persistent asymmetry in the image of Sgr A* that is not obscured by refraction due to interstellar electrons along the line of sight.

    Burn as a traumatic life incident manifests severe pain and psychological problems. Specific instruments are needed to evaluate burn patients' psychological issues related to the injury. The aim of this study was to translate and evaluate the reliability and validity of the Persian versions of Impact of Burn Specific Pain Anxiety scale (BSPAS) and Impact of Event Scale (IES). In this cross-sectional study, convenience sampling method was utilized to select 55 Iranian hospitalized burn patients. Combined translation was utilized for translating scales. Alpha cronbach, item-total correlation, convergent and discriminative validity were evaluated. The Cronbach's α for both BSPAS- and IES-Persian version was 0.96. Item-total correlation coefficients ranged from 0.70 to 0.90. Convergent construct validity was confirmed by indicating high correlation between the scales designed to measure the same concepts. The mean score of BSPAS- and IES-Persian version was lower for individuals with a lower TBSA burn percentage which assessed discriminative construct validity of scales. BSPAS- and IES-Persian version showed high internal consistency and good validity for the assessment of burn psychological outcome in hospitalized burn patients. Future studies are needed to determine repeatability, factor structure, sensitivity and specificity of the scales. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

  16. Best practices in the organization, management and conduct of an effective investigation of events at nuclear power plants

    International Nuclear Information System (INIS)

    2008-09-01

    IAEA Safety Standards Series No. SF-1 entitled Fundamental Safety Principles: Safety Fundamentals states the need for operating organizations to establish a programme for the feedback and analysis of operating experience in nuclear power plants. Such a programme ensures that operating experience is analysed, events important to safety are reviewed in depth, lessons learned are disseminated to the staff of the organization and to the relevant national and international organizations, and corrective actions are effectively implemented. This publication has been developed to provide advice and assistance to nuclear installations, and related institutions including contractors and support organizations to strengthen and enhance their own feedback process through the implementation of best practices in organization, management and conduct of an effective investigation of events. Conducting an effective investigation of events is essential in supporting a proactive safety management approach of preventing events from occurring. Event investigation is the heart of the operating experience feedback programme and in an operating organization it is essential to develop and maintain necessary expertise in this area. Experience has shown that it is not sufficient to identify only the direct causes of an event and the event is bound to recur unless all the root causes and casual factors for an event are identified and necessary corrective actions are developed and implemented. The present publication is the outcome of a coordinated effort involving the participation of experts of nuclear organizations in several Member States. It was developed to further elaborate on how to implement the event investigation requirements in the area of feedback of operating experience, as specified in the IAEA Safety Requirements publication NS-R-2 on Safety of Nuclear Power Plants: Operation. This document will also complement the publication IAEA Services Series No. 10 - PROSPER Guidelines

  18. Canada and international safeguards. Verifying nuclear non-proliferation

    International Nuclear Information System (INIS)

    1990-01-01

    The Non-Proliferation Treaty (NPT) came into force in 1970 and now has about 140 signatory nations. By creating legal barriers against proliferation and by promoting an international non-proliferation ethic, the NPT has promoted international peace and security. A key ingredient has been the confidence generated through verification by IAEA safeguards. By the end of 1988 IAEA safeguards agreements had been concluded with about 100 countries, including Canada. Over 500 nuclear facilities worldwide are under safeguards or contain safeguarded nuclear material. The existence of this credible and effective safeguards system makes international trade in nuclear equipment and materials possible, monitoring the transfer of nuclear technology to developing countries as well as between industrial countries. Canada is committed to non-proliferation and IAEA safeguards. Canadian non-proliferation policy is among the strictest in the world, even though opportunities have been lost to sell Canadian technology abroad as a result

  19. To what extent can global warming events influence scaling properties of climatic fluctuations in glacial periods?

    Science.gov (United States)

    Alberti, Tommaso; Lepreti, Fabio; Vecchio, Antonio; Carbone, Vincenzo

    2017-04-01

    The Earth's climate is an extremely unstable complex system consisting of nonlinear and still rather unknown interactions among atmosphere, land surface, ice and oceans. The system is mainly driven by solar irradiance, even if internal components as volcanic eruptions and human activities affect the atmospheric composition thus acting as a driver for climate changes. Since the extreme climate variability is the result of a set of phenomena operating from daily to multi-millennial timescales, with different correlation times, a study of the scaling properties of the system can evidence non-trivial persistent structures, internal or external physical processes. Recently, the scaling properties of the paleoclimate changes have been analyzed by distinguish between interglacial and glacial climates [Shao and Ditlevsen, 2016]. The results show that the last glacial record (20-120 kyr BP) presents some elements of multifractality, while the last interglacial period (0-10 kyr BP), say the Holocene period, seems to be characterized by a mono-fractal structure. This is associated to the absence of Dansgaard-Oeschger (DO) events in the interglacial climate that could be the cause for the absence of multifractality. This hypothesis is supported by the analysis of the period between 18 and 27 kyr BP, i.e. during the Last Glacial Period, in which a single DO event have been registred. Through the Empirical Mode Decomposition (EMD) we were able to detect a timescale separation within the Last Glacial Period (20-120 kyr BP) in two main components: a high-frequency component, related to the occurrence of DO events, and a low-frequency one, associated to the cooling/warming phase switch [Alberti et al., 2014]. Here, we investigate the scaling properties of the climate fluctuations within the Last Glacial Period, where abrupt climate changes, characterized by fast increase of temperature usually called Dansgaard-Oeschger (DO) events, have been particularly pronounced.

    Thermal-hydraulic system computer codes are extensively used worldwide for analysis of nuclear facilities by utilities, regulatory bodies, nuclear power plant designers, vendors, and research organizations. Computer code user represents a source of uncertainty that may significantly affect the results of system code calculations. Code user training and qualification represent an effective means for reducing the variation of results caused by the application of the codes by different users. This paper describes the experience in applying a systematic approach to training code users who, upon completion of the training, should be able to perform calculations making the best possible use of the capabilities of best estimate codes. In addition, this paper presents the organization and the main features of the 3D S.UN.COP (scaling, uncertainty, and 3D coupled code calculations) seminars during which particular emphasis is given to practical applications in connection with the licensing process of best estimate plus uncertainty methodologies, showing the designer, utility and regulatory approaches.

    A family of nuclear driven engines is described in which nuclear energy released by fissioning of uranium or plutonium in a prompt critical assembly is used to heat a working gas. Engine performance is modeled using a code that calculates hydrodynamics, fission energy production, and neutron transport self-consistently. Results are given demonstrating a large negative temperature coefficient that produces self-shutoff of energy production. Reduced fission product inventory and the self-shutoff provide inherent nuclear safety. It is expected that nuclear engine reactor units could be scaled from 100 MW on up. 7 refs., 3 figs

    Internal lenticonus is a very rare morphologic abnormality of crystalline lens which has been reported in only several cases in the literature. We herein reported the clinical characteristics and surgical findings of the anterior internal lenticonus accompanied by congenital nuclear cataract. Cataract extraction accompanied with intraocular lens implantation was uneventfully performed, and a good visual outcome was achieved in this case. Viral infection during embryonal and fetal period might account for the formation of the anterior internal lenticonus and congenital nuclear cataract in our case.

    Models concerning the principal phenomena, particularly thermal expansion, fuel swelling, densification, reestructuring, relocation, mechanical strain, fission gas production and release, direct or indirectly important to calculate the internal pressure in nuclear fuel rods were analysed and selected. Through these analyses a computer code was developed to calculate fuel pin internal pressure evolution. Three different models were utilized to calculate the internal pressure in order to select the best and the most conservative estimate. (Author) [pt

    1998-01-01

    As we approach the 21st Century, society's values and expectations are changing throughout the world. This change is particularly rapid in the Pacific Basin where industrialisation and economic growth is acting as the catalyst for change in every area of society. Rapid global communications, single issue pressure groups and an expectation by the general public and other stakeholders to be consulted and involved in every stage of corporate decision-making, place increased pressures upon the world's corporate structures. This paper will analyse the changes currently taking place and look forward into the next century. The author will then examine the possible impact of these societal changes upon the global nuclear industry and propose ways in which the industry can respond to these changes before they negatively impact the business. He will examine the role of nuclear power in a changing world, its relationship with its various stakeholders, and suggest ways in which the industry can gain the initiative in its communications programmes of the future. In doing this he will draw upon examples of communication campaigns from both the nuclear and other industries. (author)

  12. Policy elements for post-accident management in the event of nuclear accident. Document drawn up by the Steering Committee for the Management of the Post-Accident Phase of a Nuclear Accident (CODIRPA). Final version - 5 October 2012

    2012-01-01

    Pursuant to the Inter-ministerial Directive on the Action of the Public Authorities, dated 7 April 2005, in the face of an event triggering a radiological emergency, the National directorate on nuclear safety and radiation protection (DGSNR), which became the Nuclear safety authority (ASN) in 2006, was tasked with working the relevant Ministerial offices in order to set out the framework and outline, prepare and implement the provisions needed to address post-accident situations arising from a nuclear accident. In June 2005, the ASN set up a Steering committee for the management of the post-accident phase in the event of nuclear accident or a radiological emergency situation (CODIRPA), put in charge of drafting the related policy elements. To carry out its work, CODIRPA set up a number of thematic working groups from 2005 on, involving in total several hundred experts from different backgrounds (local information commissions, associations, elected officials, health agencies, expertise agencies, authorities, etc.). The working groups reports have been published by the ASN. Experiments on the policy elements under construction were carried out at the local level in 2010 across three nuclear sites and several of the neighbouring municipalities, as well as during national crisis drills conducted since 2008. These works gave rise to two international conferences organised by ASN in 2007 and 2011. The policy elements prepared by CODIRPA were drafted in regard to nuclear accidents of medium scale causing short-term radioactive release (less than 24 hours) that might occur at French nuclear facilities equipped with a special intervention plan (PPI). They also apply to actions to be carried out in the event of accidents during the transport of radioactive materials. Following definitions of each stage of a nuclear accident, this document lists the principles selected by CODIRPA to support management efforts subsequent to a nuclear accident. Then, it presents the main

    Within the frame of Nuclear Non-proliferation Treaty and increasing international mobility which provides opportunities for the growth of science as well as for the careers of underemployed scientists and engineers there exists a problem illegal transfer of knowledge in the field as well as nuclear material. Although there are strong cultural factors against the sale of nuclear knowledge, these constraints do not apply to mafia. International efforts should be used to improve the long-term financial and social welfare of Soviet scientists, engineers and technologists in order to prevent the attempts of would-be nuclear thieves. The international community should focus on the importance of prevention, not detection of such possibilities. Programs providing alternate civilian employment for Soviet engineers and scientists specialised in the nuclear fields should be supported

    The author first recalls the general principles of the International Humanitarian Law (IHL) and outlines its main gaps (application of the notion of protected person, classification between own territory and occupied territory). Then and in this respect, he comments the various characteristics of nuclear weapons considered as explosive devices, and notably as they are thus addressed by the International Court of Justice (ICJ). He comments the legal status of the ICJ advisory opinions, and more particularly the relationship between the ICJ advisory opinion on nuclear weapons and the IHL. Different aspects are addressed and discussed: the principle of distinction, the prohibition of the use of weapons that cause unnecessary suffering or superfluous injury. The author then comments NATO's nuclear policy in the international environment, and discusses the status and condition of nuclear deterrence. In order to address prospects for nuclear disarmament, the author notably compares differences between the arms control and non-proliferation approach, and the humanitarian disarmament approach

    Isaacs, T; Choi, J-S

    2003-01-01

    Nuclear materials were first used to end the World War II. They were produced and maintained during the cold war for global security reasons. In the succeeding 50 years since the Atoms for Peace Initiative, nuclear materials were produced and used in global civilian reactors and fuel cycles intended for peaceful purposes. The Nonproliferation Treaty (NPT) of 1970 established a framework for appropriate applications of both defense and civilian nuclear activities by nuclear weapons states and non-nuclear weapons states. As global inventories of nuclear materials continue to grow, in a diverse and dynamically changing manner, it is time to evaluate current and future trends and needed actions: what are the current circumstances, what has been done to date, what has worked and what hasn't? The aim is to identify mutually reinforcing programmatic directions, leading to global partnerships that measurably enhance international security. Essential elements are material protection, control and accountability (MPC and A) of separated nuclear materials, interim storage, and geologic repositories for all nuclear materials destined for final disposal. Cooperation among key partners, such as the MPC and A program between the U.S. and Russia for nuclear materials from dismantled weapons, is necessary for interim storage and final disposal of nuclear materials. Such cooperative partnerships can lead to a new nuclear regime where a complete fuel cycle service with fuel leasing and spent fuel take-back can be offered to reactor users. The service can effectively minimize or even eliminate the incentive or rationale for the user-countries to develop their indigenous enrichment and reprocessing technologies. International cooperation, supported by governments of key countries can be best to facilitate the forum for formation of such cooperative partnerships

    Based on the recognition that international development of nuclear industry was important by a viewpoint of international cooperation to neighboring Asian area and also it was the trump that defeated a feeling of domestic confinement, the Japan Atomic Industrial Forum (JAIF) founded Nuclear energy international development gathering' in November 2004. On that occasion our magazine (March, 2005 issue) featured 'prospects and problem of the international development of nuclear energy use'. Slightly for half a year afterwards this nuclear energy international development has been rapidly deepened and become a close-up as a policy of an important strategy of the field of nuclear energy that the government and the private sector were united to make. Therefore the nuclear energy international development was secondly featured from multidirectional points of view such as a background of nuclear energy international development, composition of international nuclear energy business, a main strategy of three makers, approach of finance / a business firm.

    Amano, Y.

    2012-01-01

    I would like to begin by thanking NRC Chairman Allison Macfarlane for hosting this first regulatory Conference on nuclear security involving regulators, law enforcement agencies and the IAEA. The United States has been a very important partner in the IAEA's nuclear security activities right from the start. It is by far the largest donor to our Nuclear Security Fund. It has actively supported our programmes and has been generous in providing funding, equipment and training to other Member States. When President Obama hosted the first Nuclear Security Summit in April 2010, he said it was important that that event should be part of a ''serious and sustained effort'' to improve nuclear security throughout the world. Since then, a growing number of governments have given high-level attention to this vitally important issue. This is very encouraging. Today, I am especially pleased to see regulators coming together to focus on this subject. I am confident that your meeting will make a valuable contribution to strengthening global nuclear security. I would like to share with you some important recent milestones in the IAEA's nuclear security work. As you know, primary responsibility for ensuring nuclear security lies with national governments. However, governments have recognized that international cooperation is vital. Terrorists and other criminals do not respect international borders and no country can respond effectively on its own to the threat which they pose. In September, our Member States - there are now 158 - reaffirmed the central role of the IAEA in e nsuring coordination of international activities in the field of nuclear security, while avoiding duplication and overlap . Our central role reflects the Agency's extensive membership, our mandate, our unique expertise and our long experience of providing technical assistance and specialist, practical guidance to countries. To put it simply, our work focuses on helping to minimize the risk of nuclear and other

These facilities support a number of DOE programs and offices including the National Nuclear Security Administration, Office of Science, and Office of Environmental Management. With many unique and “one of a kind” functions, these facilities represent a tremendous national investment, and assuring their safety and integrity is fundamental to the success of a breadth of DOE programs. Many DOE critical facilities are located in regions with significant natural phenomenon hazards including major earthquakes and DOE has been a leader in developing standards for the seismic analysis of nuclear facilities. Attaining and sustaining excellence in nuclear facility design and management must be a core competency of the DOE. An important part of nuclear facility management is the ability to monitor facilities and rapidly assess the response and integrity of the facilities after any major upset event. Experience in the western U.S. has shown that understanding facility integrity after a major earthquake is a significant challenge which, lacking key data, can require extensive effort and significant time. In the work described in the attached report, a transformational approach to earthquake monitoring of facilities is described and demonstrated. An entirely new type of optically-based sensor that can directly and accurately measure the earthquake-induced deformations of a critical facility has been developed and tested. This report summarizes large-scale shake table testing of the sensor concept on a representative steel frame building structure, and provides quantitative data on the accuracy of the sensor measurements.

    Harris, W.R.

    1978-07-01

    The rules-of-trade are those treaties, laws, executive agreements, and implementing regulations that apply to international transfers of nuclear materials, equipment, technology, or skilled personnel. The rules-of-trade are a key element in assuring the international commerce that facilitates deployment of nuclear energy will not also facilitate the manufacture of nuclear explosive devices. But the rules must be pertinent, enforceable, and understandable. The two principal problems of current rules-of-trade concern their enforceability and their flexibility; these are discussed at some length. The following additional concerns are described briefly: fast breeder reactors, spent fuel management, nonconforming parties, eligibility for international financing, fair competition and equity, and pre-existing facilities

    Full text: The development of any national nuclear energy programme is dependent on the successful development of qualified human resources, through a sustainable nuclear education and training programmes supported by government and industry. Among the broad range of specialists needed for the continued safe and economic utilization of nuclear technology for peaceful purposes, are a most vital component—managers. The International Nuclear Management Academy (INMA) is an IAEA facilitated collaboration framework in which universities provide master’s degree programmes focusing on the management aspect for the nuclear sector. INMA master’s programmes in Nuclear Technology Management (NTM) specify a common set of competency requirements that graduates should acquire to prepare them to become competent managers. This paper presents an overview of the INMA collaboration framework and the requirements for partner universities to implement master’s programmes in Nuclear Technology Management. (author

  17. Nuclear Forensics International Technical Working Group (ITWG): a collaboration of scientists, law enforcement officials, and regulators working to combat nuclear terrorism and proliferation

    2013-10-25

    Founded in 1996 upon the initiative of the “Group of 8” governments (G8), the Nuclear Forensics International Technical Working Group (ITWG) is an ad hoc organization of official Nuclear Forensics practitioners (scientists, law enforcement, and regulators) that can be called upon to provide technical assistance to the global community in the event of a seizure of nuclear or radiological materials. The ITWG is supported by and is affiliated with nearly 40 countries and international partner organizations including the International Atomic Energy Agency (IAEA), EURATOM, INTERPOL, EUROPOL, and the United Nations Interregional Crime and Justice Research Institute (UNICRI) (Figure 1). Besides providing a network of nuclear forensics laboratories that are able to assist the global community during a nuclear smuggling event, the ITWG is also committed to the advancement of the science of nuclear forensic analysis, largely through participation in periodic table top and Collaborative Materials Exercises (CMXs). Exercise scenarios use “real world” samples with realistic forensics investigation time constraints and reporting requirements. These exercises are designed to promote best practices in the field and test, evaluate, and improve new technical capabilities, methods and techniques in order to advance the science of nuclear forensics. Past efforts to advance nuclear forensic science have also included scenarios that asked laboratories to adapt conventional forensics methods (e.g. DNA, fingerprints, tool marks, and document comparisons) for collecting and preserving evidence comingled with radioactive materials.

    This report presents the evaluation of the events in 2011 in the RP-10 Nuclear Reactor Nuclear Center Huarangal from the point of view of safety. To classify these events produced is used Scale International Nuclear and Radiological Event Scale (INES) to facilitate a common understanding between the technical community, the media and the general public. From the results we can say that in 2011 all related to security events that occurred in the RP -10 are classified as 'below scale' or no safety significance. (author)

    1997-01-01

    About 250 participants from 24 Member States and seven international organizations took part in the Symposium. A wide variety of topics related to nuclear desalination were reviewed and discussed. These covered the activities of some organizations and institutes, the experience gained in existing nuclear desalination plants and their facilities, national and bilateral programmes, including research, design and development, forecasts for the future and the challenges that lie ahead. It is hoped that the Proceedings will be of value to technical, financial and regulatory decision makers associated with nuclear desalination

    Quarterly reports on the operation of Finnish nuclear power plants describe events and observations, relating to nuclear safety and radiation protection which the Finnish Centre for Radiation and Nuclear Safety considers safety significant. Safety-enhancing modifications at the nuclear power plants and issues relating to the use of nuclear energy which are of general interest are also reported. The reports include a summary of the radiation safety of plant personnel and the environment, as well as tabulated data on the production and load factors of the plants. In the first quarter of 1993, a primary feedwater system pipe break occurred at Loviisa 2, in a section of piping after a feedwater pump. The break was erosion-corrosion induced. Repairs and inspections interrupted power generation for seven days. On the International Nuclear Event Scale the event is classified as a level 2 incident. Other events in the first quarter of 1993 had no bearing on nuclear safety and radiation protection

  3. To What Extent International Law Constitutes an Appropriate Answer to Nuclear Accidents?

    International Nuclear Information System (INIS)

    2015-01-01

    Regulating high risks activities has always been an ambitious task as the regime shall both prevent and compensate the potential damage of such activities. It becomes even more complex with nuclear energy as radioactivity possesses this transboundary character which implies an international cooperation. The need for an appropriate framework for nuclear energy started to raise in the 60s, when States realise that the classic liability system was not relevant for that kind of activity. The Paris and Vienna conventions were subsequently adopted in order to fill this legal gap. Nonetheless, the real turning point remains the Chernobyl accident which resulted in a considerable number of new international instruments as 5 conventions were adopted in the fields of safety and emergency preparedness within a 11 years period: the Convention on Early Notification of a Nuclear Accident, the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency, the Convention on Nuclear Safety, the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management and the Convention on Supplementary Compensation for Nuclear Damage. This catastrophe was also the occasion to identify and mitigate the shortcomings of the existing regime in undertaking a revision process through several supplementary protocols, the Joint Protocol Relating to the Application of the Vienna Convention and the Paris Convention, the Protocol to Amend the Vienna Convention on Civil Liability for Nuclear Damage. 25 years after Chernobyl, another tragic nuclear event occurred in Fukushima. Once again it challenged the efficiency of the existing international regime and raises the question as to whether international law represents a relevant solution to such accident. (author)

    With the initiation of the first international nuclear emergency exercise INEX 1, performed as a table-top exercise in 1993, the international community tested, for the first time, approaches and policies in place to manage a nuclear or radiological emergency. INEX 1 with its related workshops led to a wealth of lessons learned and to an improvement in nuclear emergency management. The INEX 2 exercise series, initiated by the NEA and performed between 1996 and 1999, established an international nuclear emergency 'exercise culture' leading to a clear improvement of the international aspects of nuclear emergency preparedness and management. INEX 2 was a series of four command post exercises based on national nuclear emergency exercises in Switzerland, Finland, Hungary and Canada. Simulated accidents at nuclear power plants were used to test existing procedures in emergency response and management, and to analyse local, regional, national and international emergency plans under realistic conditions. In addition, the exercises allowed the participating countries to gain experience using new concepts and tools. The most significant result of INEX 2 and a major step forward in nuclear emergency management was the development of a new communication and information exchange strategy, which is currently implemented by various NEA member countries as well as by the international community in general. The objective of this new strategy is to assist the decision-maker by improving the selection of the data transmitted, by encouraging the transmission and reception of such data and information using modern communication methods, e.g. secure world wide web technologies, and by defining emergency monitoring and modelling needs. To test the validity and usefulness of the newly-developed strategy, the NEA proposed to organize an international nuclear emergency exercise, INEX 2000, similar in scope to the INEX 2 exercises. In addition, the NEA suggested to include, for the first

  6. Towards an international regime on radiation and nuclear safety

    2000-01-01

    The 1990s have seen the de facto emergence of what might be called an 'international regime on nuclear and radiation safety'. It may be construed to encompass three key elements: legally binding international undertakings among States; globally agreed international safety standards; and provisions for facilitating the application of those standards. While nuclear and radiation safety are national responsibilities, governments have long been interested in formulating harmonised approaches to radiation and nuclear safety. A principal mechanism for achieving harmonisation has been the establishment of internationally agreed safety standards and the promotion of their global application. The development of nuclear and radiation safety standards is a statutory function of the IAEA, which is unique in the United Nations system. The IAEA Statute expressly authorises the Agency 'to establish standards of safety' and 'to provide for the application of these standards'. As the following articles and supplement in this edition of the IAEA Bulletin point out, facilitating international conventions; developing safety standards; and providing mechanisms for their application are high priorities for the IAEA.

    We report large-scale molecular dynamics simulations of nuclear pasta using from 50,000 to more than 3,000,000 nucleons. We use a simple phenomenological two-nucleon potential that reproduces nuclear saturation. We find a complex ``nuclear waffle'' phase in addition to more conventional rod, plate, and sphere phases. We also find long-lived topological defects involving screw like dislocations that may reduce the electrical conductivity and thermal conductivity of lasagna phases. From MD trajectories we calculate a variety of quantities including static structure factor, dynamical response function, shear modulus and breaking strain.

  8. Sustainable, Full-Scope Nuclear Fission Energy at Planetary Scale

    Directory of Open Access Journals (Sweden)

    Robert Petroski

    2012-11-01

    Full Text Available A nuclear fission-based energy system is described that is capable of supplying the energy needs of all of human civilization for a full range of human energy use scenarios, including both very high rates of energy use and strikingly-large amounts of total energy-utilized. To achieve such “planetary scale sustainability”, this nuclear energy system integrates three nascent technologies: uranium extraction from seawater, manifestly safe breeder reactors, and deep borehole disposal of nuclear waste. In addition to these technological components, it also possesses the sociopolitical quality of manifest safety, which involves engineering to a very high degree of safety in a straightforward manner, while concurrently making the safety characteristics of the resulting nuclear systems continually manifest to society as a whole. Near-term aspects of this nuclear system are outlined, and representative parameters given for a system of global scale capable of supplying energy to a planetary population of 10 billion people at a per capita level enjoyed by contemporary Americans, i.e., of a type which might be seen a half-century hence. In addition to being sustainable from a resource standpoint, the described nuclear system is also sustainable with respect to environmental and human health impacts, including those resulting from severe accidents.

    A four-scale approach is proposed to predict the creep behavior of a concrete structure. The behavior of concrete is modeled through a numerical multiscale methodology, by successively homogenizing the viscoelastic behavior at different scales, starting from the cement paste. The homogenization is carried out by numerically constructing an effective relaxation tensor at each scale. In this framework, the impact of modifying the microstructural parameters can be directly observed on the structure response, like the interaction of the creep of concrete with the prestressing tendons network, and the effects of an internal pressure which might occur during a nuclear accident.

  10. The international politics of nuclear waste

    International Nuclear Information System (INIS)

    Blowers, Andrew; Lowry, David; Solomon, B.D.

    1991-01-01

    The dilemma of disposing nuclear waste is likened to dealing with the menace of the Ring in Tolkein's 'Lord of the Ring'; there are only two courses open 'to hide the Ring or to unmake it; both are beyond our power'. This book attempts an understanding of the contemporary politics of radioactive waste. Chapters 1 and 2 set out the background and historical context for the current position where the options have been narrowed by public opposition. The main story of the book looks at the situation in the United Kingdom, but comparisons are drawn with the USA, western Germany, Sweden and France. The studies spanned six years and are based on visits, discussions and observations. The last chapter asks the question-what are the political conditions necessary for the development of publicly acceptable policies for the management of radioactive wastes ? As Tolkein put it 'we should seek a final end of this menace, even if we do not hope to make one'. (UK)

    From various interpretations of the lunar "face," early pictograms of the Moon's phases, or to the use of the lunar cycle for festivals or harvests, the Moon has an undeniable influence on human civilization. International Observe the Moon Night (InOMN) capitalizes on the human connection to the Moon by engaging the public in annual lunar observation campaigns that share the excitement of lunar science and exploration. In 2010 (InOMN's inaugural year), over 500,000 people attended events in 53 countries around the world. About 68% of InOMN hosts - astronomy clubs, museums, schools, or other groups - used the resources on the InOMN website (http://observethemoonnight.org). The InOMN website provided supporting materials for InOMN event hosts in the form of downloadable advertising materials, Moon maps, suggestions for hands-on educational activities, and links to lunar science content. InOMN event participants shared their experiences with the world using the Web and social media, event hosts shared their experiences with evaluation data, and amateur astronomers and photographers shared their images of the Moon through the lunar photography contest. The overwhelming response from InOMN in 2010 represents an untapped potential for infusing cutting edge lunar science and exploration into a large-scale public outreach event.

    Event centrality and emotion regulation in relation to posttraumatic stress disorder (PTSD) have been documented in various global samples especially in Western cultures; but internally displaced persons (IDPs) still constitute an underrepresented population in psychotraumatology literature. This study tested the roles of event centrality and emotion regulation strategies (cognitive reappraisal and expressive suppression) in PTSD symptoms among IDPs in Nigeria. The multi-group cross-sectional design was adopted. Tiv language versions of the Centrality of Events Scale, Emotion Regulation Questionnaire, and Harvard Trauma Questionnaire were completed by 859 IDPs in two camps located in Benue State, North-central region of Nigeria. Hierarchical multiple linear regression results indicated that event centrality positively predicted PTSD symptoms. Cognitive reappraisal was a negative predictor of PTSD symptoms while expressive suppression was a positive predictor of PTSD symptoms. Bonferroni corrections indicated that expressive suppression was the strongest predictor of total PTSD symptoms, avoidance/numbing symptoms, and hyper-arousal symptoms; but event centrality was the most robust predictor of PTSD intrusion/re-experiencing symptoms. The findings underscore recent developments in psychotraumatology indicating that the extent to which individual differences impact the development of PTSD is essential in clinical psychology research and practice.

    Models of nuclear dark matter propose that the dark sector contains large composite states consisting of dark nucleons in analogy to Standard Model nuclei. We examine the direct detection phenomenology of a particular class of nuclear dark matter model at the current generation of tonne-scale liquid noble experiments, in particular DEAP-3600 and XENON1T. In our chosen nuclear dark matter scenario distinctive features arise in the recoil energy spectra due to the non-point-like nature of the composite dark matter state. We calculate the number of events required to distinguish these spectra from those of a standard point-like WIMP state with a decaying exponential recoil spectrum. In the most favourable regions of nuclear dark matter parameter space, we find that a few tens of events are needed to distinguish nuclear dark matter from WIMPs at the 3 σ level in a single experiment. Given the total exposure time of DEAP-3600 and XENON1T we find that at best a 2 σ distinction is possible by these experiments individually, while 3 σ sensitivity is reached for a range of parameters by the combination of the two experiments. We show that future upgrades of these experiments have potential to distinguish a large range of nuclear dark matter models from that of a WIMP at greater than 3 σ .

    This document contains the appendices for the accident sequence analyses of internally initiated events for the Surry Nuclear Station, Unit 1. This is one of the five plant analyses conducted as part of the NUREG-1150 effort by the Nuclear Regulatory Commission. NUREG-1150 documents the risk of a selected group of nuclear power plants. The work performed is an extensive reanalysis of that published in November 1986 as NUREG/CR-4450, Volume 3. It addresses comments from numerous reviewers and significant changes to the plant systems and procedures made since the first report. The uncertainty analysis and presentation of results are also much improved. The context and detail of this report are directed toward PRA practitioners who need to know how the work was performed and the details for use in further studies. The mean core damage frequency at Surry was calculated to be 4.0E-5 per year, with a 95% upper bound of 1.3E-4 and 5% lower bound of 6.8E-6 per year. Station blackout type accidents (loss of all AC power) were the largest contributors to the core damage frequency, accounting for approximately 68% of the total. The next type of dominant contributors were Loss of Coolant Accidents (LOCAs). These sequences account for 15% of core damage frequency. No other type of sequence accounts for more than 10% of core damage frequency

    International organisations, such as International Atomic Energy Agency, United Nations Scientific Committee on the Effects of Atomic Radiation and World Health Organisation, together with committees of experts such as Biological Effects of Ionising Radiation and Committee on Medical Aspects of Radiation in the Environment, have assessed the effects of radiation on large exposed populations (Chernobyl accident, and Hiroshima/Nagasaki atomic bombings) and on nuclear energy workers and people living near nuclear facilities. Childhood and in utero exposure to moderate and high levels of ionizing radiation, such as those experienced during the atomic bombings of Japan, or from radiotherapy, is an established cause of leukaemia and solid cancer. There is no evidence of increase in solid cancers (excluding thyroid cancer) or leukaemia in the children from Chernobyl, and no evident link between worker's exposure to radiation and leukaemia in their offspring or with the presence of leukaemia clusters around nuclear power plants. It has also not been possible to demonstrate the evidence of radiation hereditary effects in human populations. In accordance with international guidance, Canadian Nuclear Safety Commission recommends optimisation of protection strategies to reduce doses to children. The development of credible radiological/nuclear event scenarios would assist in identifying probable sources of radioactivity and pathways of exposure for children. Such scenarios should then be used to identify protection strategies appropriate for children.

There is no evidence of increase in solid cancers (excluding thyroid cancer) or leukaemia in the children from Chernobyl, and no evident link between worker's exposure to radiation and leukaemia in their offspring or with the presence of leukaemia clusters around nuclear power plants. It has also not been possible to demonstrate the evidence of radiation hereditary effects in human populations. In accordance with international guidance, Canadian Nuclear Safety Commission recommends optimisation of protection strategies to reduce doses to children. The development of credible radiological/nuclear event scenarios would assist in identifying probable sources of radioactivity and pathways of exposure for children. Such scenarios should then be used to identify protection strategies appropriate for children. (authors)

    Man power development is an essential key to success in implementing nuclear projects, especially when maximum local participation is an important issue in every sector of nuclear industry. Bearing this in mind, the Korean Atomic Energy Research Institute (KAERI) founded the Nuclear Training Center (NTC). The Center began to train technical personnel in the fields of radioisotope utilization and radiation protection in 1960s. During the first stage of nuclear power project in ROK in 1970s, the main effort was exerted to the training of those in nuclear power and nuclear engineering sectors. During the stage of increased technical self-reliance in 1980s, its training role was extended to the implementation of more specific training courses on nuclear power and safety fields. As of the end of 1995, about 23,000 people received the training courses. In an attempt to upgrade the nuclear technology, the advanced training courses at the NTC by invited foreign experts and by IAEA technical cooperation program have been implemented. Also the training under IAEA Regional Cooperative Agreement in Asia Pacific Region has been offered. The change of the NTC to the International Training Center is recommended. (K.I.)

    Concerning the number of employees, nuclear industry is the third industrial sector in France behind car industry and aeronautics. Despite the Fukushima accident nuclear power keeps its prospects high. The huge need for electrical power of emerging countries makes China and India, today's leading countries for the development of nuclear power. China launches a coal plant every week and a reactor every 4 weeks. This Chinese development must be seen as an opportunity for the French nuclear industry that has a long history of cooperation with its Chinese counterpart. In the westernized world the very low growth of the power demand and the development of renewable energies have reduced the nuclear challenge to the life-extension and safety upgrading of today operating reactors. Only 2 European countries: United-Kingdom and Poland have nuclear programs. It is a necessity for the French nuclear industry to contribute to the international development of nuclear power for 2 reasons: first to stay innovative by using up-to-date technologies in building reactors and secondly to be ready and competitive for the future replacement of the French fleet of reactors.

    Security strategies, for many centuries, have been based on boundaries: the strategic placement of cities and borders to take advantage of natural barriers; defences that relied on walls, trenches and armadas; and the use of ethnic, religious or other groupings to distinguish friend from foe. In the 20th Century, the advent of airplanes, submarines and ballistic missiles began to undermine this approach to security by enabling the remote delivery of destruction on a scale previously not envisioned. But the change that has altered the international security landscape the most drastically is, in fact, globalization. The global community has become interdependent, with the constant movement of people, ideas and goods. Many aspects of modern life, communication, the global marketplace and, most recently, the rise in international terrorism - clearly indicate that our understanding of and approaches to national and international security must be adjusted, in keeping with new realities. This statement discusses: Nuclear Security and the Protection Against Nuclear Terrorism, IAEA Nuclear Security Plan of Activities founded on measures to guard against thefts of nuclear and other radioactive material and to protect related facilities against malicious acts; cooperation with other organizations and efforts

    In light of the exceptional circumstances that arose from hosting the Olympic Games in Athens in 2004 and from recent terrorist events internationally, Greece attributes the highest priority to security issues. According to its statutory role, the Greek Atomic Energy Commission is responsible for emergency preparedness and response in case of nuclear and radiological events, and advises the Government on the measures and interventions necessary to protect the public. In this context, the Commission participated in the Nuclear, Radiological, Biological, and Chemical Threat National Emergency Plan, specially developed for the Olympic Games, and coordinated by the Olympic Games Security Division. The objective of this paper is to share the experience gained during the organization of the Olympic Games and to present the nuclear security program implemented prior to, during, and beyond the Games, in order to prevent, detect, assess, and respond to the threat of nuclear terrorism. This program adopted a multi-area coverage of nuclear security, including physical protection of nuclear and radiological facilities, prevention of smuggling of radioactive materials through borders, prevention of dispersion of these materials into the Olympic venues, enhancement of emergency preparedness and response to radiological events, upgrading of the technical infrastructure, establishment of new procedures for assessing the threat and responding to radiological incidents, and training personnel belonging to several organizations involved in the National Emergency Response Plan. Finally, the close cooperation of Greek Authorities with the International Atomic Energy Agency and the U.S. Department of Energy, under the coordination of the Greek Atomic Energy Commission, is also discussed.

    A retrieval engine developed to extract event sequences from an accident information database using a time series retrieval formula expressed with ordered retrieval terms is explored. This engine outputs not only a sequence which completely matches with a time series retrieval formula, but also sequence which approximately matches the formula (fuzzy retrieval). An event sequence database in which records consist of three ordered parameters, namely the causal event, the process and result. Then the database is used to assess the feasibility of this engine and favorable results were obtained. (author)

  9. Strengthening the international legal framework for nuclear security: Better sooner rather than later

    2016-01-01

    In this 21. century global environment, the threat of terrorists or other criminals eventually acquiring and using radioactive material for malicious purposes or sabotaging such material or associated facilities, could be calculated as being an inevitable, albeit a preventable catastrophe. Much has been done to address this situation, such as the International Atomic Energy Agency (IAEA) now having a recognised central role in strengthening nuclear security globally. However, concerns still remain regarding the adequacy of the global nuclear security architecture, consisting of legally binding and non-binding instruments, intergovernmental organisations (IGOs), bodies and various initiatives, as well as internationally-accepted guidance and best practices, such as those reflected in the IAEA Nuclear Security Series of publications. Issues arise with respect to the adequacy of the international framework for nuclear security and the level of effective national implementation thereof. Highlighted in this regard, is a lack of universal adherence to the international nuclear security legal instruments, an absence of sustained information sharing (particularly on national implementation) and the non-existence of binding nuclear security standards and mandatory peer review and assessment. This article examines the framework's adequacy, its gaps and weak links, as well as the measures proposed to strengthen it. Part 1 considers some past and recent events, efforts, and developments that have contributed to the current status. Thereafter, the purported gaps and weak links and proposed strengthening measures are identified. While acknowledging progress, it is assumed that some overarching considerations, particularly national sovereignty, secrecy and complacency, continue to restrictively influence and determine the extent of state behaviour. Accordingly, these considerations are also briefly addressed in Part 1. Thereafter, Part 2 provides a concise overview of the

    The use of nuclear technology in medicine, agriculture and industry is very advanced in Morocco. This technological progress has been accompanied by fairly detailed legislation and significant involvement on the part of Morocco in international conventions and agreements. The desire to progress further with regard to research and the use of nuclear energy for peaceful purposes requires a twofold effort: the various pieces of national legislation on nuclear law need to be reformulated to bring them into line with the most recent rules in this sphere; Morocco international undertakings need to be revised in light of its immediate interests, certainly, but also of foreseeable developments, particularly with regard to safety and third party liability.

    1999-01-01

    An NEA study on safety research needs of Russian-designed reactors, carried out in 1996, strongly recommended that a strategic plan for safety research be developed with respect to Russian nuclear power plants. Such a plan was developed at the Russian International Nuclear Safety Centre (RINSC) of the Russian Ministry of Atomic Energy (Minatom). The Strategic Plan is designed to address high-priority safety-research needs, through a combination of domestic research, the application of appropriate foreign knowledge, and collaboration. It represents major progress toward developing a comprehensive and coherent safety-research programme for Russian nuclear power plants (NPPs). The NEA undertook its review of the Strategic Plan with the objective of providing independent verification on the scope, priority, and content of the research described in the Plan based upon the experience of the international group of experts. The principal conclusions of the review and the general comments of the NEA group are presented. (K.A.)

    Fuels is to document the development of multi-scale modelling approaches for fuels in support of current fuel optimisation programmes and innovative fuel designs. The objectives of the effort are: - assess international multi-scale modelling approaches devoted to nuclear fuels from the atomic to the macroscopic scale in order to share and promote such approaches; - address all types of fuels: both current (mainly oxide fuels) and advanced fuels (such as minor actinide containing oxide, carbide, nitride, or metal fuels); - address key engineering issues associated with each type of fuel; - assess the quality of existing links between the various scales and list needs for strengthening multi-scale modelling approaches; - identify the most relevant experimental data or experimental characterisation techniques that are missing for validation of fuel multi-scale modelling; - promote exchange between the actors involved at various scales; - promote exchange between multi-scale modelling experts and experimentalists; - exchange information with other expert groups of the WPMM. This report is organised as follows: - Part I lays out the different classes of phenomena relevant to nuclear fuel behaviour. Each chapter is further divided into topics relevant for each class of phenomena. - Part II is devoted to a description of the techniques used to obtain material properties necessary for describing the phenomena and their assessment. - Part III covers details relative to the principles and limits behind each modelling/computational technique as a reference for more detailed information. Included within the appropriate sections are critical analyses of the mid- and long-term challenges for the future (i.e., approximations, methods, scales, key experimental data, characterisation techniques missing or to be strengthened)

  18. The protection against nuclear risks under the international nuclear liability law: the geographical and technical scope of the international conventions on third party liability for nuclear damage

    International Nuclear Information System (INIS)

    Kissich, S.J.

    2001-10-01

    This Ph.D.-research deals with the International Conventions on Third Party Liability for Nuclear Damage. In 1960, the Paris Convention was established with the aim of providing a special uniform nuclear third party liability regime for Western Europe. This Convention was supplemented in 1963 by the Brussels Supplementary Convention. Also in 1963, the Vienna Convention, which aimed to establish a world-wide system based on the same principles as the Paris Convention, was adopted. A further Convention was adopted in 1971 to ensure that nuclear third party liability law and not maritime law would apply to carriage of nuclear materials by sea. In 1988, the Paris and Vienna Conventions have been linked by the adoption of a Joint Protocol. In 1997, the process of amending the 1963 Vienna Convention was successfully concluded and a Convention on Supplementary Compensation was adopted. This Ph.D.-research consists of seven chapters: following an introduction, the second chapter gives a general view of the existing international legal sources. The third chapter describes the international civil nuclear liability law concept and its leading principles. The main element of this work is the question of the technical and geographical scope of the international nuclear liability conventions (chapter IV and V). The conventions are only applicable to nuclear incidents, which occur in a nuclear installation or incidental to the carriage or storage of nuclear material. The nuclear damage must arise out of the radioactive properties of nuclear substances which are also defined by legal terms. In addition, the scope of the conventions is limited by the nature of the installations. The geographical scope of application is established by the provisions on geographical coverage. Only the 1963 Vienna Convention does not contain any specific provision dealing with the territorial scope of its application. The geographical scope determines where the nuclear incident or the nuclear damage

    2000-01-01

    One of the primary objectives of the Slovak Nuclear Regulatory Authority (UJD) Public Relations Program is to make available to the public full and complete information on UJD activities to assist the public in making informed judgments regarding UJD activities. The primary means of keeping the public informed about the regulatory activities and programs of the UJD is through the news media. A central state administration body, the UJD provides on request within its province in particular information on operational safety of nuclear energy installations independently of those responsible for the nuclear programme, thereby allowing the public and the media to control data and information on nuclear installations. A major element of providing information is the demonstration that the area of nuclear energy uses has its binding rules in the Slovak Republic and the observance thereof is controlled by the state through an independent institution - UJD. As early as 1995 were laid on the UJD the foundations of the concept of broadly keeping the public informed on UJD activity and the safety of nuclear installations by opening the UJD Information Centre. Information Centre provides by its activity communications with the public and mass media, which is instrumental in creating in the public a favourable picture of the independent state nuclear regulation. Internal and external communications are equally important

    Since its creation in 1970 until 1996, the International Nuclear Information System (INIS) collected and converted to microfiche over 312 000 non-conventional literature (NCL) reports received from IAEA member states and international organizations. The microfiche collection contains over 1 million items, with an estimated total of 25 million pages of full-texts. In 1997, the INIS Secretariat replaced the microfiche-based production system with an imaging system to process and to disseminate all NCL documents in electronic format. That marked the beginning of digital preservation efforts that still continue today. This paper provides an overview of the digital preservation practices and the technical infrastructure of the International Nuclear Information System (INIS). It describes the technical processes, the standards in place, the hardware and software used, as well as all practices related to scanning, quality control, OCR, preservation and storage. (author)

    Dose assessment in case of internal exposure involves the estimation of committed effective dose based on the interpretation of bioassay measurement, and the assumptions of hypotheses on the characteristics of the radioactive material and the time pattern and the pathway of intake. In the case of workers exposed in nuclear fuel facilities, the normal uranium excretion from the diet is an additional difficulty in the process of assessing internal exposure. The aim of this paper is to present the main topics discussion and the conclusions of the workshop, held in the frame of the missions of the Autoridad Regulatoria Nuclear. All the personnel involved in the control of internal exposure in nuclear fuel cycle was invited to participate in the workshop to discuss about individual monitoring criteria and the available tools for assessing committed effective dose in the workers of their facilities. The lectures were presented jointly by the Nuclear Fuel Cycle Facilities Control and the Dosimetric and Radiobiological Assessment departments. It was hold at the Ezeiza Atomic Center from 23th to 24th November 2010 based on the Advanced Course on Internal Dosimetry organized on 2009 and focusing specific uranium compound internal dosimetry. A representative of each facility was invited to present the monitoring program implemented for controlling the internal exposure. It was an opportunity to discuss criteria and to share experiences on this field in the frame of the ICRP, HPA and ISO publications. The different monitoring program criteria could be analyzed and so contributing to the improvement of radiological protection. Finally, it was agreed to hold periodical meetings to assure the update on uranium measurement techniques and the handling of monitoring data for committed effective dose assessment. (authors) [es

    This document written to obtain the French accreditation to supervise research presents the research I conducted at CEA Cadarache since 1999 on the atomic scale modelling of non-metallic materials involved in the nuclear fuel cycle: host materials for radionuclides from nuclear waste (apatites), fuel (in particular uranium dioxide) and ceramic cladding materials (silicon carbide). These are complex materials at the frontier of modelling capabilities since they contain heavy elements (rare earths or actinides), exhibit complex structures or chemical compositions and/or are subjected to irradiation effects: creation of point defects and fission products, amorphization. The objective of my studies is to bring further insight into the physics and chemistry of the elementary processes involved using atomic scale modelling and its coupling with higher scale models and experimental studies. This work is organised in two parts: on the one hand the development, adaptation and implementation of atomic scale modelling methods and validation of the approximations used; on the other hand the application of these methods to the investigation of nuclear materials under irradiation. This document contains a synthesis of the studies performed, orientations for future research, a detailed resume and a list of publications and communications. (author)

  7. Intercontinental nuclear transport from the private international law perspective

    International Nuclear Information System (INIS)

    Magnus, U.

    2000-01-01

    The aim of this paper is to give a survey on choice of law rules which apply outside the nuclear liability conventions in case of damage caused by international nuclear transports. We found a remarkable variety of solutions. Some of the solutions make it difficult or even impossible to predict in advance which substantive law in a hypothetical case would apply. These difficulties are increased by the fact that more often than not, a victim can choose where to sue and thereby also influence the final outcome of a case. As far as private international law rules apply - and as mentioned the non-ratification of the nuclear liability conventions by many nuclear states forces us to fall back on the choice of law rules in many cases - the applicable law and the hypothetical level of compensation therefore often remain uncertain when judged at the time of organisation of the nuclear transport. However, at this time the question of undertaking risks and of insurability must be decided. (author)

    International Atomic Energy Agency (IAEA) is an organization under the United Nations (UN), which serves to disseminate accurate information about the nuclear world. In accordance with its role, an International Nuclear Information System (INIS) was established in 1970, provides the opportunities for member countries under the auspices of the IAEA to share information, expertise and knowledge, particularly in the nuclear field. Malaysia has become a member since 1978, and the first country input was posted in the 1980's. INIS member countries are supervised by a specially appointed liaison officers to monitor and oversee matters related to that. Each issue is associated with 49 subject matter (subject heading) will be checked and recorded by using Win fibre before being sent to the INIS database at IAEA headquarters in Vienna, Austria. Material received will be distributed directly to all IAEA member states through the INIS web site and CD distribution to subscribers countries. Today, INIS is still a successful nuclear-related information provider through nearly 3 million data have been recorded including journals, reports, scientific papers, patents, nuclear laws, the web sites contents, and many more.

    The OECD Nuclear Energy Agency (NEA) is organising a co-operation between the major nuclear data evaluation projects in the world. The co-operation involves the ENDF, JEFF, and JENDL projects, and, owing to the collaboration with the International Atomic Energy Agency (IAEA), also the Russian RUSFOND and the Chinese CENDL projects. The Working Party on international nuclear data Evaluation Cooperation (WPEC), comprised of about 20 core members, manages this co-operation and meets annually to discuss progress in each evaluation project and also related experimental activities. The WPEC assesses common needs for nuclear data improvements and these needs are then addressed by initiating joint evaluation efforts. The work is performed in specially established subgroups, consisting of experts from the participating evaluation projects. The outcome of these subgroups is published in reports, issued by the NEA. Current WPEC activities comprise for example a number of studies related to nuclear data uncertainties, including a review of methods for the combined use of integral experiments and covariance data, as well as evaluations of some of the major actinides, such as {sup 235}U and {sup 239}Pu. This paper gives an overview of current and planned activities within the WPEC.

    2009-12-01

    The internal consistency of the Human Behavior Rating Scale (HBRS) was investigated. The 91-item Likert-type scale is designed to measure five dimensions: persistence, curiosity, externalizing affect, internalizing affect, and cognition. It is used as a research tool to investigate the tenets of Eaves' 1993 integrated theory of human behavior. Three separate sampling plans were employed. Teachers and nonteachers completed Human Behavior Rating Scale ratings of children ranging in age from 5 to 18 years old. Cronbach coefficients alpha were reported by sex, grade, or age for the three samples. Of the 185 reported alpha coefficients, 175 were at or above .90, while 10 had values between .80 and .89.

  20. The responsibility of nuclear suppliers in the international market

    International Nuclear Information System (INIS)

    Thiessen, C.W.; Cotton, J.D.; Tait, B.I.

    1978-01-01

    As a result of escalating oil prices, the developing countries are more and more turning to nuclear energy. As these countries become a more significant part of the international market, unique issues must be faced by the utility and country concerned and the nuclear supplier. A fundamental prerequisite of a successful supplier/customer relationship is a good relationship between their two governments. The supplier can fulfil an effective liaison function to ensure efficiency of communications in this area. In the preplanning phase the supplier can play a major role in supplying information relative to siting, unit size, system planning and plant economics. Once the nuclear choice is made, the pros and cons of purchasing plants on a turnkey versus non-turnkey basis must be weighed. The customer must balance his available resources and experience against his desires for acquisition of overall plant and systems knowledge. During the planning and procurement phase the subject of training, maintenance and service facilities can be an effective part of a comprehensive nuclear programme. In fact, local training and service centres could logically be the first step of a long-term localization effort. With respect to localization the supplier should be capable and experienced in developing this capability and willing to make a long-term commitment in this area. Through a clearer understanding of the responsibilities of the nuclear supplier and a clear delineation of his role, developing nations can more adequately assess the basis upon which to move forward on a nuclear programme.

  1. Organizing irresponsibility? The (inter)national management of a nuclear accident damages as discursive regime

    International Nuclear Information System (INIS)

    Topcu, Sezin

    2014-01-01

    This article analyzes the historical process related to the international organization of responsibilities and the management of the damages in case of a nuclear disaster. The author shows that the political and legal settings on which the discourse of an 'international regime of civil responsibility' (that emerged in the 1960's) relies, have globally aimed at maintaining a 'historical and spectacular gap' between the damages the nuclear operators are taking responsibility for, and the real and extensive damages engendered by a major accident. She argues that the existence of such a 'gap' is inherent to the nuclear sector, that it is a form of government (both of economic affairs and of the public space) which was historically constructed, and that the existence of such a gap is crucial for the survival of the nuclear industry itself. Thus the notion of 'responsibility' in the nuclear sector appears to serve mainly as a discursive regime, as a means to organize not only responsibilities but also irresponsibilities, whatever the geographic scale (national or international) at which they should be managed

  3. Large-scale coordinated observations of Pc5 pulsation events

    Full Text Available HF (high-frequency radars belonging to SuperDARN (Super Dual Auroral Radar Network receive backscatter over substantial fields of view which, when combined, allow for simultaneous returns over extensive regions of the polar caps and midlatitudes. This makes them ideal instruments for the observation of pulsations in the Pc5 (1–5 mHz frequency band. Relatively few pulsation events observed by multiple radars have been reported in the literature. Here we describe observations of three such events which extend over more than 120° of magnetic longitude in the Northern Hemisphere and one of which is also detected in the Southern Hemisphere. All three events show characteristics of field line resonances. In one case the pulsation has also been observed by magnetometers under or near the radar fields of view. The extensive longitudinal coverage allows accurate determination of azimuthal wave numbers. These are at the upper end of the lower values associated with external sources such as those in the solar wind. Such sources imply antisunward flow. However, the azimuthal wave number is negative, implying westward propagation at magnetic local times on both sides of noon, as would be expected from drift–bounce resonance with positive particles. Quiet conditions and a very low ring current during the events argue against this. The identification of the source of pulsations from a number of different mechanisms remains a problem of interest.

    To meet the growing trend of computational requirements in JAERI, introduction of a high-speed computer with vector processing faculty (a vector processor) is desirable in the near future. To make effective use of a vector processor, appropriate optimization of nuclear codes to pipelined-vector architecture is vital, which will pose new problems concerning code development and maintenance. In this report, vector processing efficiency is assessed with respect to large-scale nuclear codes by examining the following items: 1) The present feature of computational load in JAERI is analyzed by compiling the computer utilization statistics. 2) Vector processing efficiency is estimated for the ten heavily-used nuclear codes by analyzing their dynamic behaviors run on a scalar machine. 3) Vector processing efficiency is measured for the other five nuclear codes by using the current vector processors, FACOM 230-75 APU and CRAY-1. 4) Effectiveness of applying a high-speed vector processor to nuclear codes is evaluated by taking account of the characteristics in JAERI jobs. Problems of vector processors are also discussed from the view points of code performance and ease of use. (author)

    The primary result of the project is the establishment of a concept of International Nuclear R and D Academy that integrates the on-going long term activity for international nuclear education/training and a new activity to establish an international cooperation network for nuclear human resources development. For this, the 2007 WNU Summer Institute was hosted with the establishment of an MOU and subsequent preparations. Also, ANENT was promoted through development of a cyber platform for the ANENT web-portal, hosting the third ANENT Coordination Committee meeting, etc. Then a cooperation with universities in Vietnam was launched resulting in preparation of an MOU for the cooperation. Finally, a relevant system framework was established and required procedures were drafted especially for providing students from developing countries with long term education/training programs (e.g. MS and Ph D. courses). The international nuclear education/training programs have offered 13 courses to 182 people from 43 countries. The overall performance of the courses was evaluated to be outstanding. In parallel, the establishment of an MOU for the cooperation of KOICA-IAEA-KAERI courses to ensure their stable and systematic operation. Also, an effort was made to participate in FNCA. Atopia Hall of the International Nuclear Training and Education Center (INTEC) hosted 477 events (corresponding to 18,521 participants) and Nuri Hall (guesthouse) accommodated 4,616 people in 2006. This shows a steady increase of the use rate since the opening of the center, along with a continuous improvement of the equipment.

  7. Survey of large-scale isotope applications: nuclear technology field

    Energy Technology Data Exchange (ETDEWEB)

    Dewitt, R.

    1977-01-21

    A preliminary literature survey of potential large-scale isotope applications was made according to topical fields; i.e., nuclear, biological, medical, environmental, agricultural, geological, and industrial. Other than the possible expansion of established large-scale isotope applications such as uranium, boron, lithium, and hydrogen, no new immediate isotope usage appears to be developing. Over the long term a change in emphasis for isotope applications was identified which appears to be more responsive to societal concerns for health, the environment, and the conservation of materials and energy. For gram-scale applications, a variety of isotopes may be required for use as nonradioactive ''activable'' tracers. A more detailed survey of the nuclear field identified a potential need for large amounts (tons) of special isotopic materials for advanced reactor components and structures. At this need for special materials and the development of efficient separation methods progresses, the utilization of isotopes from nuclear wastes for beneficial uses should also progress.

    1986-10-01

    This document contains the internal event initiated accident sequence analyses for Peach Bottom, Unit 2; one of the reference plants being examined as part of the NUREG-1150 effort by the Nuclear Regulatory Commission. NUREG-1150 will document the risk of a selected group of nuclear power plants. As part of that work, this report contains the overall core damage frequency estimate for Peach Bottom, Unit 2, and the accompanying plant damage state frequencies. Sensitivity and uncertainty analyses provided additional insights regarding the dominant contributors to the Peach Bottom core damage frequency estimate. The mean core damage frequency at Peach Bottom was calculated to be 8.2E-6. Station blackout type accidents (loss of all ac power) were found to dominate the overall results. Anticipated Transient Without Scram accidents were also found to be non-negligible contributors. The numerical results are largely driven by common mode failure probability estimates and to some extent, human error. Because of significant data and analysis uncertainties in these two areas (important, for instance, to the most dominant scenario in this study), it is recommended that the results of the uncertainty and sensitivity analyses be considered before any actions are taken based on this analysis

    This document contains the appendices for the accident sequence analysis of internally initiated events for the Peach Bottom, Unit 2 Nuclear Power Plant. This is one of the five plant analyses conducted as part of the NUREG-1150 effort for the Nuclear Regulatory Commission. The work performed and described here is an extensive reanalysis of that published in October 1986 as NUREG/CR-4550, Volume 4. It addresses comments from numerous reviewers and significant changes to the plant systems and procedures made since the first report. The uncertainty analysis and presentation of results are also much improved, and considerable effort was expended on an improved analysis of loss of offsite power. The content and detail of this report is directed toward PRA practitioners who need to know how the work was done and the details for use in further studies. The mean core damage frequency is 4.5E-6 with 5% and 95% uncertainty bounds of 3.5E-7 and 1.3E-5, respectively. Station blackout type accidents (loss of all ac power) contributed about 46% of the core damage frequency with Anticipated Transient Without Scram (ATWS) accidents contributing another 42%. The numerical results are driven by loss of offsite power, transients with the power conversion system initially available operator errors, and mechanical failure to scram. 13 refs., 345 figs., 171 tabs.

  10. Filtering large-scale event collections using a combination of supervised and unsupervised learning for event trigger classification.

    Biomedical event extraction is one of the key tasks in biomedical text mining, supporting various applications such as database curation and hypothesis generation. Several systems, some of which have been applied at a large scale, have been introduced to solve this task. Past studies have shown that the identification of the phrases describing biological processes, also known as trigger detection, is a crucial part of event extraction, and notable overall performance gains can be obtained by solely focusing on this sub-task. In this paper we propose a novel approach for filtering falsely identified triggers from large-scale event databases, thus improving the quality of knowledge extraction. Our method relies on state-of-the-art word embeddings, event statistics gathered from the whole biomedical literature, and both supervised and unsupervised machine learning techniques. We focus on EVEX, an event database covering the whole PubMed and PubMed Central Open Access literature containing more than 40 million extracted events. The top most frequent EVEX trigger words are hierarchically clustered, and the resulting cluster tree is pruned to identify words that can never act as triggers regardless of their context. For rarely occurring trigger words we introduce a supervised approach trained on the combination of trigger word classification produced by the unsupervised clustering method and manual annotation. The method is evaluated on the official test set of BioNLP Shared Task on Event Extraction. The evaluation shows that the method can be used to improve the performance of the state-of-the-art event extraction systems. This successful effort also translates into removing 1,338,075 of potentially incorrect events from EVEX, thus greatly improving the quality of the data. The method is not solely bound to the EVEX resource and can be thus used to improve the quality of any event extraction system or database. The data and source code for this work are available at

  11. International convention for the suppression of acts of nuclear terrorism

    2005-01-01

    The Preamble, composed of 13 paragraphs and drafted in the usual style of a General Assembly resolution, is aimed at placing the convention in a number of relevant contexts. First, the convention is linked to the issue of the maintenance of international peace and security through a reference to the purposes of the United Nations under Article 1 of the Charter. Next, it is presented as being a further step in the decisions, measures and instruments developed by the United Nations over the past ten years with the common objective of eliminating international terrorism in all its forms. Lastly, the convention is placed in its specific nuclear context through a number of references. In its third paragraph, the Preamble contains a reference to the principle recognizing 'the right of all states to develop and apply nuclear energy for peaceful purposes and their legitimate interests in the potential benefits to be derived from the peaceful application of nuclear energy'. This paragraph is identical to the first paragraph of the Preamble of the CPPNM, and the same principle is stated again in the first paragraph of the Preamble of the Amendment to the CPPNM, and constitutes a kind of general statement in favour of the peaceful use of nuclear energy and technology, without explicit reservations concerning non-proliferation, the safety and security of nuclear facilities or the management of radioactive waste. A draft amendment presented by the United States delegation in the final phase of work that suggested adding the phrase 'while recognizing that the goals of peaceful utilisation should not be used as a cover for proliferation' to the sentence cited above, was apparently not retained. Next, the Preamble mentions the 1980 Convention on the Physical Protection of Nuclear Material, and in the tenth paragraph the threat that 'acts of nuclear terrorism may result in the gravest consequences and may pose a threat to international peace and security'. Paragraph 11 of the

    The American Nuclear Society's (ANS's) International Student Exchange Program sponsors bilateral exchanges of students form graduate schools in American universities with students from graduate schools in France, the Federal Republic of Germany (FRG), and Japan. The program, now in its 12th year, was initiated in response to an inquiry to Argonne National Laboratory (ANL) from the director of the Centre d'Etudes Nucleaires de Saclay proposing to send French nuclear engineering students to the United States for summer jobs. The laboratory was asked to accept two students to work on some nuclear technology activity and ANS was invited to send American students to France on an exchange basis. To date, 200 students have taken part in the program. It has been a maturing and enriching experience for them, and many strong and enduring friendships have been fostered among the participants, many of whom will become future leaders in their countries

    1992-05-01

    As the US Department of Energy (DOE) and DOE contractors have become increasingly involved with other nations in nuclear fuel cycle and waste management cooperative activities, a need exists costs for a ready source of information concerning foreign fuel cycle programs, facilities, and personnel. This Fact Book has been compiled to meet that need. The information contained in the International Nuclear Fuel Cycle Fact Book has been obtained from many unclassified sources: nuclear trade journals and newsletters; reports of foreign visits and visitors; CEC, IAEA, and OECD/NMEA activities reports; and proceedings of conferences and workshops. The data listed typically do not reflect any single source but frequently represent a consolidation/combination of information.

  14. Tomography in nuclear medicine. Proceedings of an international symposium

    International Nuclear Information System (INIS)

    1996-01-01

    Single photon emission computed tomography (SPECT) is currently being used universally in clinical practice, while positron emission tomography (PET), originally developed as a technique for research, has also gradually moved from the research laboratory to the clinical environment. However, there are significant differences in nuclear medicine capabilities, especially in tomography, between developed and developing countries. The present status and future prospects of nuclear medicine tomography were the main topics of discussion at this latest international symposium, organized by the IAEA in co-operation with the World Health Organization and held in Vienna from 21 to 25 August 1995. The purpose of the meeting was to share experience and information on new developments and clinical applications of two promising tomographic techniques: SPECT and PET. Eight invited papers and 34 regular papers from 23 countries were presented. In addition, there was a panel discussion on the future and direction of tomography in nuclear medicine for developing countries. Refs, figs, tabs

  16. Adaptation to extreme climate events at a regional scale

    OpenAIRE

    Hoffmann, Christin

    2017-01-01

    A significant increase of the frequency, the intensity and the duration of extreme climate events in Switzerland induces the need to find a strategy to deal with the damages they cause. For more than two decades, mitigation has been the main objective of climate policy. However, due to already high atmospheric carbon concentrations and the inertia of the climate system, climate change is unavoidable to some degree, even if today’s emissions were almost completely cut back. Along with the high...

    Full text: Introduction: Modern nuclear medicine (NM) metabolic therapy involves treatment with radionuclides sources mainly β-, and lately more often and α- rays and aims target specificity to the disease process with minimal damage to healthy surrounding tissues. Materials and Methods: We present some of the most important clinically significant contemporary trends in metabolic therapy in the light of international experience, including low-known in Bulgaria peptide radioreceptor therapy, radioimmunotherapy and so called SIRT (Selective internal radiation therapy) for liver metastases. Results: The ability of NM therapy range from definitive treatment of benign thyroid disease and differentiated thyroid cancer by achieving partial response or complete remission to a temporary palliative analgesic and symptom reducing effect in different, mainly cancer, diseases. Conclusion: The principle of 'terradiagnostic' - the interdependence of diagnostic and therapeutic nuclear medicine approaches is crucial for individualizing treatment and achieving better results in extending survival and improving the quality of life of patients

    The present dissertation analyses the retaking of the debate over Brazilian nuclear Program's recovery by Luis Inacio Lula da Silva government, based on the defense of the utilization of an already acquired technology of its own to enrich uranium. In spite of the intrinsic duality on this subject and having in mind the pacific ends concerning the utilization of such technology by Brazil, the hypothesis sustained in this work is that the Program's defense is considered a strategy of sovereign international insertion with relative autonomy and an instrument of national valorization against other powers. In order to verify the hypothesis outlined above, we will analyse the actual government, comparing it to, two other moments in Brazilian History in which the nuclear issue also acquired preponderance on the national agenda, namely, Geisel and Sarney governments. Although these three moments differ in relation to their internal political regime, our goal is to identify their similarities. (author)

  19. Non-equilibrium effects of core-cooling and time-dependent internal heating on mantle flush events

    Directory of Open Access Journals (Sweden)

    D. A. Yuen

    1995-01-01

    Full Text Available We have examined the non-equilibrium effects of core-cooling and time-dependent internal-heating on the thermal evolution of the Earth's mantle and on mantle flush events caused by the two major phase transitions. Both two- and three-dimensional models have been employed. The mantle viscosity responds to the secular cooling through changes in the averaged temperature field. A viscosity which decreases algebraically with the average temperature has been considered. The time-dependent internal-heating is prescribed to decrease exponentially with a single decay time. We have studied the thermal histories with initial Rayleigh numbers between 2 x 107 and 108 . Flush events, driven by the non-equilibrium forcings, are much more dramatic than those produced by the equilibrium boundary conditions and constant internal heating. Multiple flush events are found under non-equilibrium conditions in which there is very little internal heating or very fast decay rates of internal-heating. Otherwise, the flush events take place in a relatively continuous fashion. Prior to massive flush events small-scale percolative structures appear in the 3D temperature fields. Time-dependent signatures, such as the surface heat flux, also exhibits high frequency oscillatory patterns prior to massive flush events. These two observations suggest that the flush event may be a self-organized critical phenomenon. The Nusselt number as a function of the time-varying Ra does not follow the Nusselt vs. Rayleigh number power-law relationship based on equilibrium (constant temperature boundary conditions. Instead Nu(t may vary non-monotonically with time because of the mantle flush events. Convective processes in the mantle operate quite differently under non-equilibrium conditions from its behaviour under the usual equilibrium situations.

    2017-09-01

    Collisions of heavy ions are carried out at ultra relativistic speeds at the Relativistic Heavy Ion Collider and the Large Hadron Collider to create Quark Gluon Plasma. The earliest stages of such collisions are dominated by the dynamics of classical gluon fields. The McLerran-Venugopalan (MV) model of color glass condensate provides a model for this process. Previous research has provided an analytic solution for event averaged observables in the MV model. Using the High Performance Research Computing Center (HPRC) at Texas A&M, we have developed a C++ code to explicitly calculate the initial gluon fields and energy momentum tensor event by event using the analytic recursive solution. The code has been tested against previously known analytic results up to fourth order. We have also have been able to test the convergence of the recursive solution at high orders in time and studied the time evolution of color glass condensate.

    , for that impact. Externality is one type of failure that causes inefficiency.' Like other energy sources, nuclear energy has risks and benefits that need to be fully recognized and assessed to evaluate its external costs. The external costs of nuclear energy include: radioactive waste disposal, future financial liabilities arising from decommissioning and dismantling of nuclear facilities, health and environmental impact of radioactivity releases in routine operation and effects of severe accidents. Beyond the competitive generation costs of existing nuclear power plants in most markets, benefits of nuclear power, that are not reflected currently in prices, include: security of supply, cost stability and the quasi absence of atmospheric emissions of greenhouse gases, other pollutant gases and particulates. The capital and operating costs of nuclear power plants and fuel cycle facilities already internalize a major portion of the above-mentioned potential external costs, and these are reflected in the prices paid by consumers of nuclear-generated electricity. This paper presents a few aspects on externalities of nuclear power and current approach on the internalization of external costs on radioactive waste disposal and decommissioning of the Cernavoda Nuclear Power Plant. The paper contents as follows: 1. Introduction; 2. External costs; 3. Positive externalities of nuclear electricity; 4. Actions relevant to internalize future liabilities for nuclear power in Romania; 5. Conclusions. In conclusion the capital and operating costs of nuclear power plants already internalize a major portion of the above-mentioned potential external costs, and these are reflected in the prices paid by consumers of nuclear-generated electricity. If externalities such as: security of supply, cost stability and broad economic impacts on employment and balance of trade would be internalized, the effect would be positive for nuclear energy.

  6. Discrete-event simulation of nuclear-waste transport in geologic sites subject to disruptive events. Final report

    International Nuclear Information System (INIS)

    Aggarwal, S.; Ryland, S.; Peck, R.

    1980-01-01

    This report outlines a methodology to study the effects of disruptive events on nuclear waste material in stable geologic sites. The methodology is based upon developing a discrete events model that can be simulated on the computer. This methodology allows a natural development of simulation models that use computer resources in an efficient manner. Accurate modeling in this area depends in large part upon accurate modeling of ion transport behavior in the storage media. Unfortunately, developments in this area are not at a stage where there is any consensus on proper models for such transport. Consequently, our work is directed primarily towards showing how disruptive events can be properly incorporated in such a model, rather than as a predictive tool at this stage. When and if proper geologic parameters can be determined, then it would be possible to use this as a predictive model. Assumptions and their bases are discussed, and the mathematical and computer model are described

  11. Consideration of external events in the design of nuclear facilities other than nuclear power plants, with emphasis on earthquakes

    International Nuclear Information System (INIS)

    2003-03-01

    The design of nuclear facilities other than nuclear power plants in relation to external events is not a well harmonized practice around the world. Traditionally, the design of these facilities has either been left to the provisions collected in national building codes and other industrial codes not specifically intended for nuclear facilities, or it has been the subject of complex analyses of the type usually performed for nuclear power plants. The IAEA has recently started a programme of development of safety standards for such facilities. The need to define the appropriate safety requirements for nuclear installations prompted a generic review of siting and design approaches for these facilities in relation to external events. Therefore the assessment methods for siting and design were reviewed by the engineering community to provide the overall design of such facilities with the necessary reliability level. This report aims to provide guidelines for the assessment of the safety of nuclear facilities other than nuclear power plants in relation to external events through the application of simplified methods and procedures for their siting and design. The approach adopted is both simplified and conservative compared with that used for power reactors. It seeks to provide a rational balance for a suitable combination of sustainable effort in site investigations and refinement in design procedures, compatible with the assigned safety objectives. This publication is related to IAEA-TECDOC-348 'Earthquake Resistant Design of Nuclear Facilities with Limited Radioactive Inventory' (1985) which focused on the seismic design of nuclear facilities with limited radioactive inventory. After some 17 years, parts of IAEA-TECDOC-348 needed modification, as new operational data have become available from many facilities. In addition, sophisticated design methodologies are now more easily obtainable, and experts felt that the trade-off between sustainable investment in the

    The transfer of technology from developed countries is usually done through industrial enterprises. The local industrialization of imported technology does not necessarily imply that full benefit is extracted from its application. A pre-established scientific and technical infrastructure is needed to understand and incorporate it, and to develop methods for improvement and use at the industrial level, in the frame of national conditions. The transference of nuclear technology has recently shown new concepts for implementation. It is becoming a rule that massive industrial nuclear technology transfer to developing nations is tied to a requirement for simultaneous assistance in creating or promoting the infrastructure. An example of international co-operation to meet this requirement is the Argentine-German Agreement for the Peaceful Applications of Nuclear Energy. Since 1971 this has been used to strengthen the scientific and technical programmes of the Argentine Atomic Energy Commission in the relevant fields of industrial applications. The objectives and implementation of the agreement are described: co-operative actions were initially directed to the infrastructure needed to support the nuclear fuel cycle industry. The results achieved during the period 1971-1976 are critically analysed. This analysis has influenced the selection of future co-operative projects as well as the extension of the co-operation to other nuclear fields of common interest. (author)

  13. Developments in international convention on nuclear third party liability

    2000-01-01

    A few years after the adoption of a Protocol to amend the world-wide Vienna Convention on Civil Liability for Nuclear Damage and of a new ''global'' Convention on the Supplementary Compensation of Nuclear Damage (September 1997), the countries which are party to the Western Europe based Paris and Brussels Conventions are working on the revision of these instruments within the OECD Nuclear Energy Agency. The objective of this exercise is not only to preserve the compatibility of the Paris and Vienna provisions, which is now an imperative deriving from the application of the 1988 Joint Protocol linking these two Conventions, but also to substantially improve certain features of this regime such as its technical and geographical scope of application, the facilitation of the rights of victims to defend their claims and, of course, the level of funds effectively available to compensate the damage. This paper reviews briefly the recent evolution of the international nuclear liability regime and discusses some of the challenges which the nuclear countries are facing in this context. (author)

    In this panel discussing nonproliferation and international cooperation, the point of view of developing countries, both signatories and nonsignatories to the NPT, is presented. The slow-down in the growth of nuclear trade and industry has adversely affected the economy of energy deficient developing countries, depriving them of the benefits of atomic energy in agriculture and health as well as in power sector. Among 26 countries using nuclear energy for electricity generation, there are just half a dozen developing countries, and their share in the installed nuclear power capacity in the world is only 2 %. Besides the overall slow-down of global economy, the inflexible framework of treaties and quidelines is an important factor of the slow-down. The gradual erosion of mutual confidence between supplier states and recipients has arisen. The greatest threat to world peace is the growing nuclear arsenals of superpowers rather than nuclear proliferation. The role of the IAEA, the setting up of the Committee on Assurance of Supplies, the economy of developing countries and others are discussed. (Kako, I.)

    A cosmic-ray induced nuclear event detected in the emulsion chamber is described. The event consists of 217 shower cores with ΣEγ = 1,275 TeV. In log scale, energy and particles are emitted most densely at the small lateral distance corresponding to 0.5 mm; 77 % of the total energy and 61 % of the total multiplicity are inside the radius of 0.65 cm. The shower cores in the central region show exponential-type energy distribution and non-isotropic azimuthal distribution. This event indicates a possibility that phenomena of large transverse momentum could happen to produce a strong concentration of energy and particles in the very forward direction. (Authors) [pt

    From the PSA point of view, the Fukushima accident of Japan in 2011 reveals some issues to be re-considered and/or improved in the PSA such as the limited scope of the PSA, site risk, etc. KAERI (Korea Atomic Energy Research Institute) has performed researches on the development of an integrated risk assessment framework related to some issues arisen after the Fukushima accident. This framework can cover the internal PSA model and external PSA models (fire, flooding, and seismic PSA models) in the full power and the low power-shutdown modes. This framework also integrates level 1, 2 and 3 PSA to quantify the risk of nuclear facilities more efficiently and consistently. We expect that this framework will be helpful to resolve the issue regarding the limited scope of PSA and to reduce some inconsistencies that might exist between (1) the internal and external PSA, and (2) full power mode PSA and low power-shutdown PSA models. In addition, KAERI is starting researches related to the extreme external events, the risk assessment of spent fuel pool, and the site risk. These emerging issues will be incorporated into the integrated risk assessment framework. In this paper the integrated risk assessment framework and the research activities on the emerging issues are outlined.

    It is essential for Korea to enlarge nuclear energy utilization and development and to develop nuclear fuel cycle technology. However some domestic and international restraints are existing to achieve above goals. Therefore, the consideration for the environmental prospect of nuclear energy development is needed to solve those restraints. The current North Korea's policies and future relations between two countries in Korean peninsular in respect to domestic restraints are examined and forecasted in Chapter 2. This analysis tries to develop new approaches to solve internal and external major problems through forecasting the future on nuclear nonproliferation policy of U. S. An in-depth study on resolving international and inter-Korean restrictions in political and strategic perspectives is carried out in Chapter 3. The various policy alternatives to adjust the constraints of the joint declaration are proposed and analysed in Chapter. It contains also the national commitments that are suggested as ideas on how to advance the long-term nuclear research and development under the present situation. (author). 100 refs

    Full Text Available We report on a recent work on the low-energy behavior of the breakup cross section in so far as it has important role in the fusion of weakly bound and halo nuclei at near-barrier energies. We assess the way the nuclear component of this cross section scales with the target mass. In complete accord with previous finding at higher energies we verify that the low energy behavior of the breakup cross section for a given projectile and relative center of mass energy with respect to the Coulomb barrier height scales as the cubic root of the mass number of the target. Surprisingly we find that the Coulomb component of the breakup cross section at these low energies also obeys scaling, but with a linear dependence on the target charge. Our findings are important when planning for experiments involving these exotic nuclei.

    2016-01-01

    This paper reviews recent research on the application of the physical dosimetry techniques of electron paramagnetic resonance (EPR) and luminescence (optically stimulated luminescence, OSL, and thermoluminescence, TL) to determine radiation dose following catastrophic, large-scale radiological events. Such data are used in dose reconstruction to obtain estimates of dose due to the exposure to external sources of radiation, primarily gamma radiation, by individual members of the public and by populations. The EPR and luminescence techniques have been applied to a wide range of radiological studies, including nuclear bomb detonation (e.g., Hiroshima and Nagasaki), nuclear power plant accidents (e.g., Chernobyl), radioactive pollution (e.g., Mayak plutonium facility), and in the future could include terrorist events involving the dispersal of radioactive materials. In this review we examine the application of these techniques in ‘emergency’ and ‘retrospective’ modes of operation that are conducted on two distinct timescales. For emergency dosimetry immediate action to evaluate dose to individuals following radiation exposure is required to assess deterministic biological effects and to enable rapid medical triage. Retrospective dosimetry, on the other hand, contributes to the reconstruction of doses to populations and individuals following external exposure, and contributes to the long-term study of stochastic processes and the consequential epidemiological effects. Although internal exposure, via ingestion of radionuclides for example, can be a potentially significant contributor to dose, this review is confined to those dose components arising from exposure to external radiation, which in most studies is gamma radiation. The nascent emergency dosimetry measurement techniques aim to perform direct dose evaluations for individuals who, as members of the public, are most unlikely to be carrying a dosimeter issued for radiation monitoring purposes in the event

Among them, the first one addresses the issue of energy transition (perspectives in France, situation in Germany where transition appears to be expensive and polluting with some perverse effects, a world shock wave created by shale gases, proposition by EDF to extend power station life duration from 40 to 50 years, EDF's commitment in nuclear revival in the UK and withdrawal from the USA, new strategy for GDF-Suez) and the second one current events in the renewable energy sector (in China, Germany, UK and Canada, French policy, wind energy bids in France). A second set of articles addresses the nuclear sector: recent evolutions of the uranium industry (mining activities and locations), the back end of the fuel cycle and the dismantling (activities of AREVA, public debate on Cigeo and building permit for ICEDA in France, activities and measures in Germany, in England, in the USA, and in Japan, study performed by the Nuclear Energy Agency on the economic aspect of the back end of the nuclear fuel cycle), the situation of nuclear reactors (perspectives in the world for 2050, perspectives, activities and important events in France, Belgium, Netherlands, United Kingdom, Finland, including the EPR, Turkey, Poland, Czech Republic, Belarus, Russia, China, South Korea, India, Pakistan, Japan, USA and Brazil), the deconstruction of nuclear power plants (legal framework in France, wastes as a major issue for dismantling, industrial challenges of dismantling). The last set of articles concern social and societal aspects of the nuclear sector: recent events in France (for AREVA regarding staff and investments, anti-nuclear activities and momentum), the Cigeo project of geological disposal of high-activity nuclear wastes, hostages in Niger, and diplomatic advances about the Iranian nuclear programme issue

    Full text: Senior nuclear regulators today concluded a Workshop on the Lessons Learned from the IAEA Integrated Regulatory Review Service (IRRS) Missions. The U.S. Nuclear Regulatory Commission (NRC) hosted the workshop, in cooperation with the International Atomic Energy Agency, in Washington, DC, from 26 to 28 October 2011. About 60 senior regulators from 22 IAEA Member States took part in this workshop. The IRRS programme is an international peer review service offered by the IAEA to its Member States to provide an objective evaluation of their nuclear safety regulatory framework. The review is based on the internationally recognized IAEA Safety Standards. ''The United States Nuclear Regulatory Commission was pleased to host the IAEA's IRRS meeting this week. The discussions over the past three days have provided an important opportunity for regulators from many countries to come together to strengthen the international peer review process,'' said U.S. NRC Chairman Gregory B. Jaczko. ''Especially after the Fukushima Daiichi accident, the global community recognizes that IRRS missions fill a vital role in strengthening nuclear safety and security programs around the world, and we are proud to be a part of this important effort.'' The IAEA Action Plan on Nuclear Safety includes actions focused towards strengthening the existing IAEA peer reviews, incorporating lessons learned and improving their effectiveness. The workshop provided a platform for the exchange of information, experience and lessons learned from the IRRS missions, as well as expectations for the IRRS programme for the near future. Further improvements in the planning and implementation of the IRRS missions in the longer term were discussed. A strong commitment of all relevant national authorities to the IRRS programme was identified as a key element of an effective regulatory framework. The conclusions of the workshop will be issued in November 2011 and the main results will be reported to the IAEA

    The International Nuclear Physics Conference 2010 (INPC 2010) was held from 4-9 July in Vancouver, Canada, hosted by TRIUMF, the Canadian National Laboratory for Particle and Nuclear Physics. The INPC is the main conference in the field of nuclear physics, endorsed and supported by IUPAP (International Union for Pure and Applied Physics) and held every three years. This year's conference was the 25th in the series and attracted over 750 delegates (150 graduate students) from 43 countries. The conference's hallmark is its breadth in nuclear physics; topics included structure, reactions, astrophysics, hadronic structure, hadrons in nuclei, hot and dense QCD, new accelerators and underground nuclear physics facilities, neutrinos and nuclei, and applications and interdisciplinary research. The conference started with a public lecture 'An Atom from Vancouver' by L Krauss (Arizona), who gave a broad perspective on how nuclear physics is key to a deeper understanding of how the Universe was formed and the birth, life, and death of stars. The conference opened its scientific plenary program with a talk by P Braun-Munzinger (GSI/EMMI Darmstadt) who highlighted the progress that has been made since the last conference in Tokyo 2007. The presentation showcased theoretical and experimental examples from around the world. All topics were well represented by plenary sessions and well attended afternoon parallel sessions where over 250 invited and contributed talks were presented, in addition to over 380 poster presentations. The poster sessions were among the liveliest, with high participation and animated discussions from graduate students and post-doctoral fellows. Many opportunities were found to connect to fellow nuclear physicists across the globe and, particularly for conferences like the INPC which span an entire field, many unexpected links exist, often leading to new discussions or collaborations. Among the scientific highlights were the presentations in the fields of

  11. International standardization of nuclear reactor designs - the way forward

    The concept of 'International Standardization of Nuclear Reactor Designs' means that vendors could build their designs in every country without having to adapt it specifically to national safety requirements. Such standardization would have two main effects. It would greatly facilitate nuclear new build worldwide by giving greater efficiency and certainty to the national licensing procedures; by taking into account the fact that vendors, and nowadays also utilities, are active across borders; by helping developing countries to establish their nuclear new build programmes; and by reducing the strain on human resources on both the regulators' and the industry's side. The second valuable effect of standardization would be to further enhance safety by improving the exchange of construction and operating experience among a number of reactors belonging to fleets of the same design. The World Nuclear Association's CORDEL (Cooperation in Reactor Design Evaluation and Licensing) Group has developed a concept for implementation of international standardization of reactor designs. It has defined a number of steps to be taken by industry. At the same time, possibilities offered by national and international regulatory mechanisms would have to be fully made use of, and some changes in regulatory frameworks might be necessary. Some steps especially towards greater cooperation of regulators have already been taken; however, much still remains to be done. The concept of deploying standardized reactor designs across a number of countries supposes an alignment and, if possible, harmonization of national safety standards; a streamlining of national licensing procedures, making them more efficient and predictable; and the willingness of national regulators to take into account licensing done in other countries. In the end, this should lead to a mutual acceptance of design approvals or, in a more distant future, even to a multinational design approval process. All in all, the concept

    In general, the Emergency Planning Zones (EPZ) are defined as well as plant site and arrangement structures are designed to minimize the potential for natural and manmade hazards external to the plant from affecting the plant safety related functions, which can affect nearby population and environment. This may include consideration of extreme winds, fires, flooding, aircraft crash, seismic activity, etc. Thus the design basis for plant and site is deeply related to the effects of any postulated external events and the limitation of the plant capability to cope with accidents i.e. perform safety functions. It has been observed that the Probabilistic Safety Assessment (PSA) methodologies to deal with EPZ and extreme external events have not reached the same level of maturity as for severe internal events. The design basis for any plant and site is deeply related to the effects of any postulated external events and the limitation of the plant capability to cope with accidents i.e. perform safety functions. As a prime example of an advanced reactor and new Nuclear Power Plant (NPP) with enhanced safety, the International Reactor Innovative and Secure (IRIS) and Site selection for New NPP in Lithuania had been considered in this work. In the used Safety-by-Design™ approach, the PSA played obviously a key role; therefore a Preliminary IRIS PSA had been developed along with the design. For the design and pre-licensing process of IRIS the external events analysis included both qualitative evaluation and quantitative assessment. As a result of preliminary qualitative analyses, the external events that were chosen for more detailed quantitative scoping evaluation were high winds and tornadoes, aircraft crash, and seismic events. For the site selection in Lithuania a detail site evaluation process was performed and related to the EPZ and risk zoning considerations. In general, applying the quantitative assessment, bounding site characteristics could be used in order to

    We report our efforts in the development of Nuclear Magnetic Resonance Force Microscopy (NMRFM) for dynamical imaging of liquid media at the micron scale. Our probe contains microfluidic samples sealed in thin-walled (µm) quartz tubes, with a micro-oscillator sensor nearby in vacuum to maintain its high mechanical resonance quality factor. Using 10 µm spherical permalloy magnets at the oscillator tips, a 3D T1-resolved image of spin density can be obtained by reconstruction from our magnetostatics-modelled resonance slices; as part of this effort, we are exploring single-shot T1 measurements for faster dynamical imaging. We aim to further enhance imaging by using a 2 ω technique to eliminate artifact signals during the cyclic inversion of nuclear spins. The ultimate intent of these efforts is to perform magnetic resonance imaging of individual biological cells.

    An adverse event in a nuclear power plant occurs due to either one cause or multiple causes. To consider ways of preventing adverse events, it is useful to clarify whether events are caused by single or multiple causes. In this study, the multiple causes is expressed using the cause multiplicity and the multiple cause style. Classified causes of adverse events in Japanese nuclear power plants were analyzed, with the following results: the cause multiplicity of serious adverse events is higher than that of minor adverse events, and the multiple cause style can be expressed by combining two styles: series type and parallel type. Also, for a multiple cause event, a new method of displaying the event is presented as a cause-chain chart where the cause items are arranged in a sequential way and are connected considering the mutual relations among the causes. This new display method shows the whole flow of issues concerning the event more simply than the conventional display method of the chain of phenomena, and would be useful for considering the terminating point of the chain of causes.

  15. Trend analysis of nuclear reactor automatic trip events subjected to operator's human error at United States nuclear power plants

    Trends in nuclear reactor automatic trip events due to human errors during plant operating mode have been analyzed by extracting 20 events which took place in the United States during the period of seven years from 2002 to 2008, cited in the LERs (Licensee Event Reports) submitted to the US Nuclear Regulatory Commission (NRC). It was shown that the yearly number of events was relatively large before 2005, and thereafter the number decreased. A period of stable operation, in which the yearly number was kept very small, continued for about three years, and then the yearly number turned to increase again. Before 2005, automatic trip events occurred more frequently during periodic inspections or start-up/shut-down operations. The recent trends, however, indicate that trip events became more frequent due to human errors during daily operations. Human errors were mostly caused by the self-conceit and carelessness of operators through the whole period. The before mentioned trends in the yearly number of events might be explained as follows. The decrease in the automatic trip events is attributed to sharing trouble information, leading as a consequence to improvement of the manual and training for the operations which have a higher potential risk of automatic trip. Then, while the period of stable operation continued, some operators came to pay less attention to preventing human errors and not interest in the training, leading to automatic trip events in reality due to miss-operation. From these analyses on trouble experiences in the US, we learnt the followings to prevent the occurrence similar troubles in Japan: Operators should be thoroughly skilled in basic actions to prevent human errors as persons concerned. And it should be further emphasized that they should elaborate by imaging actual plant operations even though the simulator training gives them successful experiences. (author)

  16. INIS Today. An Introduction to the International Nuclear Information System

    International Nuclear Information System (INIS)

    1979-01-01

    What is INIS? The acronym INIS stands for International Nuclear Information System. INIS was planned and is operated by the International Atomic Energy Agency (IAEA) in collaboration with its Member States. Its purpose is to provide a comprehensive nuclear information and abstracting service, using modern computer and micrographic techniques. This includes: 1. processing input received from Member States, 2. providing Member States with output in a variety of forms for dissemination on a national basis, and 3. assisting Member States in improving their methods of information handling. History: The origins of INIS go back to 1965. In that year the IAEA, recognizing that it had a statutory obligation to foster the exchange of nuclear information amongst its members, invited consultants from the USSR and from the USA to draw up an outline scheme for an international information system, that would cover adequately the expanding amount of literature on the peaceful uses of atomic energy. The consultants proposed to the IAEA a cooperative system, one that would serve the information requirements of countries of varying levels of development and with different backgrounds and traditions in the methods and techniques of information handling. The system would make use of the latest computer and micrographic techniques. During the next few years the consultants' proposals were submitted by the Agency to a number of international panels of experts for discussion and elaboration into a detailed systems design. In February 1969, the Board of Governors of the IAEA approved the setting up of INIS on an experimental basis. The first output products of the new system were issued in April 1970.

    A suggestion is made to make legal dispositions for the distribution of funds before a nuclear event. The concept incorporates the following material-legal elements: Proportionate reduction of damages compensation claims in case the funds for liability and coverage are insufficient; creation of reserve funds for late damage; legal preference of personal damage and only subsequent satisfaction of demand for compensation of nuclear industries.

  18. Stakeholder involvement in nuclear issues. INSAG-20. A report by the International Nuclear Safety Group

    International Nuclear Information System (INIS)

    2006-01-01

    Many of the world's nuclear power plants were constructed long ago without much public involvement in the associated decision making. It is anticipated, however, that a variety of stakeholders will seek participation in such decisions now as the nuclear option is being revisited in many places. Accidents at Three Mile Island and Chernobyl, among other places, have served to arouse public concern. The development of 'here-and-now' media capabilities has created an awareness that may not have previously existed. Improvements in educational systems and the development of the Internet have made technical information and expertise available to individuals and locations that were previously without them. In addition, consideration of the environmental impacts of various energy strategies has moved to the fore. INSAG has concluded that the expectations of stakeholders of a right to participate in energy decisions are something that the nuclear community must address. Decisions regarding such matters as the siting and construction of a nuclear power plant are no longer largely the domain of a closed community of technical experts and utility executives. Today, the concerns and expectations of all manner of persons and organizations - from the local farmer to the international financial institution - must be considered. This report is intended for use by all stakeholders in the nuclear community - national regulatory authorities, nuclear power plant designers and operators, public interest organizations and individuals, the media and, not to be forgotten, local and national populations. INSAG's fundamental conclusion is that all stakeholders with an interest in nuclear decisions should be provided with an opportunity for full and effective participation in them. With this right, however, come certain obligations on all sides for openness, candour and civility. INSAG is hopeful that this report will help define the interests and roles of the stakeholders in the nuclear

    This proceedings volume contains the invited lectures and contributions presented at the International Summer School on Nuclear Physics held at Trei Brazi, a summer resort of the Bioterra University, near the city of Predeal, Romania, on 9-20 July 2012. The long tradition of International Summer Schools on Nuclear Physics in Romania dates as far back as 1964, with the event being scheduled every two years. During this period of almost 50 years, many outstanding nuclear scientists have lectured on various topics related to nuclear physics and particle physics. This year we celebrate the 80th birthday of Aureliu Sandulescu, one of the founders of the Romanian school of theoretical nuclear physics. He was Serban Titeica's PhD student, one of Werner Heisenberg's PhD students, and he organized the first edition of this event. Aureliu Sandulescu's major contributions to the field of theoretical nuclear physics are related in particular to the prediction of cluster radioactivity, the physics of open quantum systems and the innovative technique of detecting superheavy nuclei using the double magic projectile 48Ca (Calcium), nowadays a widely used method at the JINR—Dubna and GSI—Darmstadt laboratories. The title of the event, 'Dynamics of Open Nuclear Systems', is in recognition of Aureliu Sandulescu's great personality. The lectures were attended by Romanian and foreign Master and PhD students and young researchers in nuclear physics. About 25 reputable professors and researchers in nuclear physics delivered lectures during this period. According to a well-established tradition, an interval of two hours was allotted for each lecture (including discussions). Therefore we kept a balance between the school and conference format. Two lectures were held during the morning and afternoon sessions. After lecture sessions, three or four oral contributions were given by young scientists. This was a good opportunity for them to present the results of their research in front of

  20. West German nuclear politics: a study of international cooperative behavior

    Driscoll, R.F.

    1983-01-01

    This dissertation is an investigation of the motivations behind West German policies and behavior in the area of nuclear politics. It examines and attempts to explain this behavior using a taxonomy built around the factors of vulnerability, power, domestic support, and autonomy. These are called international cooperative behavior factors. Chapters I and II develop the taxonomy and define the factors in terms of the Federal Republic. Chapter III covers the period up through the functioning of the Nuclear Planning Group, while Chapter IV analyzes NATO's December 1979 modernization decision. The presentation is less chronological and more selective: it focuses on the four international cooperative behavior factors as explanatory concepts. Chapter V examines the utility of the taxonomy. It concludes that the factors of autonomy, domestic support and vulnerability appear to be key in understanding and predicting West German nuclear behavior. The chapter then studies the potential applicability of the taxonomy to other nations or issues. It concludes that the factors are very nation-specific, but they do in fact provide a useful classification and explanatory scheme
