    Abstract: Proper heat removal from the fuel is essential for the safe operation of nuclear reactors used for electricity production. As nuclear fuel is burnt it undergoes important changes, including a degradation of its thermal conductivity. This important phenomenon needs to be reliably predicted in order to make better use of the fuel, a factor which can help to achieve the economic competitiveness required by today's markets. This report communicates the results of an international seminar which reviewed recent progress in the field of nuclear fuel thermal conductivity and sought to improve the models used in computer codes predicting thermal performance. State-of-the-art knowledge is presented for both uranium-oxide and mixed-oxide fuels loaded in water reactors.

    Abstract: Radioactive and stable isotopes are used throughout the world and in many sectors, including medicine, industry, agriculture and research. In many applications isotopes have no substitute, and in most others they are more effective and cheaper than alternative techniques or processes. This publication is the first international survey on the beneficial uses and production of isotopes. It provides an overview of their main uses, and detailed information on the facilities that produce them world-wide. Trends in isotope supply and demand are analysed, and the conclusions and recommendations presented point to key issues to be considered by governments.

    Abstract: Plutonium and minor actinide burning or recycling in thermal and fast reactors is being studied in many countries with the aim of maintaining and developing fuel cycle options which can be adjusted to changing demands and constraints. The challenge is to move towards an economically and socially sustainable nuclear energy system based on advanced reactors - advanced water-cooled reactors, fast reactors and perhaps accelerator-based, hybrid reactors - and new types of fuel cycles which help to minimise the waste arising. An additional issue concerns the availability of resources for the long-term future. This workshop introduced new ideas on R&D activities and identified areas and research tasks relevant for the deployment of new systems and in which international co-operation can be strengthened. The roles played by existing experimental facilities as well as possible needs for new ones are discussed. The conclusions of the technical sessions are synthesised and the results of a round table discussion on international co-operation are presented.

    Abstract: The use of ion beams in nuclear research is well established, with many facilities and networks of experts active in the field. Applications for ion beams are expanding, in particular in the development of new materials, biotechnology and the creation of new isotopes. Positron beams are likewise a very powerful tool for observing and influencing microscopic material structures, as well as for medical diagnosis. The combined utilisation of ion and positron beams is expected to open up new horizons in the areas of material science and biotechnology. These proceedings provide an overview of the latest developments in this field, and highlight areas for future international co-operation.

    Abstract: Following recent disarmament agreements, the Russian Federation and the USA have declared part of their stockpiles of weapons-grade plutonium as a surplus to their national defense needs. This material needs to be disposed of, and one of the suggested means of doing so is burning it in existing reactors and transforming the material into spent fuel. The experience in these two countries with mixed oxide fuel (MOX) is either dated or scarce. Several European countries and Japan, however, have acquired much experience in using MOX fuel in reactors which was shared at this important workshop. This publication presents the workshop results which reviewed existing technical information from the civil nuclear power programmes that are beneficial to weapons-grade plutonium disposition. It also proposes concrete actions that could help expedite this process in the near future.

    Abstract: The concept of removing long-lived radioactive wastes from the human environment by disposal in deep geological repositories was developed several decades ago. In the intervening years, research efforts world-wide have increased our knowledge and understanding of how underground disposal systems will function over very long periods of time. Significant progress has also been made towards implementation of such facilities. There have, however, been delays in the disposal programmes of several countries. This report is a review of developments in the past decade. The primary sources of information are the answers to a questionnaire provided by waste management organisations represented in the NEA Radioactive Waste Management Committee (RWMC). The latter is an international forum of senior specialists from safety authorities, waste management agencies, R&D institutions and policy-making bodies.

    Abstract: In its 1994 collective opinion, Radiation Protection Today and Tomorrow, the NEA Committee on Radiation Protection and Public Health (CRPPH) concluded that societal participation in the decision-making process is becoming increasingly important. This was seen as particularly true in the case of decisions involving complex radiological situations such as those following a nuclear or radiological accident (for example, the Chernobyl accident, or fallout from atomic bomb testing in the Marshall Islands), and other long-lasting exposures (such as areas contaminated by uranium mill tailings). In order to explore this issue further, the CRPPH organised a workshop in January 1998 on the societal aspects of decision making in complex radiological situations. At the workshop - which was hosted in Villigen, Switzerland, by the Swiss Federal Nuclear Safety Inspectorate (HSK) - participants concluded that it is no longer possible to take decisions in such situations without a transparent process involving the public from a very early stage. This decision-making process, which is described herein, was also seen as being valuable for other situations, such as the siting of high-level nuclear waste repositories. Recommendations for follow-up by the CRPPH are also included.

    Abstract: Les politiques de libéralisation des secteurs énergétiques posent des défis majeurs aux autorités chargées de la sûreté nucléaire. Avec l'ouverture à la concurrence et la déréglementation, il est plus que jamais nécessaire de concilier les intérêts commerciaux et les impératifs de sûreté. Le premier défi que devront relever les autorités de sûreté est de s'assurer que les considérations économiques n'ont pas d'effet néfaste sur la sûreté nucléaire. Mais ces autorités devront également conserver toute leur efficacité et s'adapter à un environnnement de plus en plus régi par les lois du marché, tout en jouant un rôle central pour maintenir la « culture de sûreté » face à un nouveau comportement des exploitants. Ce rapport recense les défis réglementaires que les autorités de sûreté seront susceptibles de rencontrer dans les dix ans qui viennent.

    Abstract: Major nuclear regulatory challenges will arise from government policies to liberalise energy sectors. In a context of growing competition and market deregulation, it is becoming increasingly important to reconcile commercial interests with safety requirements. For nuclear regulatory bodies, the first challenge will be to ensure that economic pressures do not erode nuclear safety. In their strive to maintain nuclear safety culture, regulatory bodies will also need to adapt to an increasingly market-oriented environment and new working relationships with operators. This report identifies the challenges that regulators are likely to be confronted with over the next ten years.
