Uranium is the main raw material fuelling all nuclear fission reactors today. Countries around the world use it to reliably generate low-carbon electricity, process heat and hydrogen as part of their plans to reduce carbon emissions and increase energy security and supply. There is no nuclear fission power possible - of whatever kind - without uranium. This 29th edition of the "Red Book", a recognised world reference on uranium jointly prepared by the Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA), provides analyses and information from 54 uranium producing and consuming countries. The present edition reviews world uranium market fundamentals and presents data on global uranium exploration, resources, production and reactor-related requirements. It offers updated information on established uranium production centres and mine development plans, as well as projections of nuclear generating capacity and reactor-related requirements through 2040.

The implementation of advanced nuclear systems requires that new technologies associated with the back end of the fuel cycle are developed. The separation of minor actinides from other fuel components is one of the advanced concepts being studied to help close the nuclear fuel cycle and to improve the long-term effects on the performance of geological repositories. Separating spent fuel elements and subsequently converting them through transmutation into short-lived nuclides should considerably reduce the longterm risks associated with nuclear power generation. R&D programmes worldwide are attempting to address such challenges, and many processes for advanced reprocessing and partitioning minor actinides are being developed. This report provides a comprehensive overview of progress on separation chemistry processes, and in particular on the technologies associated with the separation and recovery of minor actinides for recycling so as to help move towards the implementation of advanced fuel cycles. The report examines both aqueous and pyro processes, as well as the status of current and proposed technologies described according to the hierarchy of separations targeting different fuel components. The process criteria that will affect technology downselection are also reviewed, as are non-proliferation requirements. The maturity of different reprocessing techniques are assessed using a scale based on the technology readiness level, and perspectives for future R&D are reviewed.

The nuclear sector has in recent years been placing increasing attention on the need to better understand variations between cost estimates for the decommissioning of nuclear power plants, as well as the relationship between estimated and actual costs, and the apparent escalation of these costs. Building on previous work by the Nuclear Energy Agency, Cost Benchmarking for Nuclear Power Plant Decommissioning examines approaches and methods for the benchmarking of nuclear power plant decommissioning costs. Particular focus is given to identifying key factors, drivers and constraints to implementing cost benchmarking. These factors are addressed from a broad range of perspectives in order to develop a roadmap for implementation that will garner sufficiently broad support from a wide base of interested stakeholders. The report also identifies a number of perceived barriers that may impede the implementation of benchmarking for decommissioning. Co-ordinated efforts and further analysis will be needed to help remove these barriers.

Les isotopes radioactifs et stables sont utilisés à travers le monde dans de nombreux secteurs, notamment en médecine, dans l'industrie, l'agriculture et la recherche. Les isotopes sont irremplaçables dans bon nombre de leurs applications et s'avèrent généralement plus efficaces et moins chers que d'autres techniques ou procédés. Cette publication est la première étude internationale sur les usages bénéfiques et la production d'isotopes. Elle donne une vue d'ensemble de leurs principaux usages ainsi que des informations détaillées sur les installations qui les produisent à travers le monde. Les tendances de l'offre et de la demande d'isotopes sont analysées. Enfin, les conclusions et recommandations qui sont faites signalent aux organismes gouvernementaux les questions clés qu'il leur faut examiner. Cette publication sera utile aux décideurs des agences gouvernementales impliquées dans la production et l'utilisation des isotopes ainsi qu'aux chercheurs et aux experts travaillant dans ce domaine.
