Advanced nuclear fuel cycles and radioactive waste management nuclear energy agency

Advanced fuel cycle options address some of the problems raised by the long-term radiotoxicity of high-level waste (HLW) by burning most of the long-lived minor actinides. Reducing the amount of actinides to be disposed of does not facilitate the short- and medium-term waste management, because a key issue during that timeframe is the heat generated by fission products. However, advanced separation technologies may offer alternatives for the management of the “trouble-maker” fission products, such as nuclides generating large amounts of heat. Earlier studies have concluded that partitioning facilities for actinides (such as plutonium, americium, curium and neptunium) and some long-lived fission products could be designed and constructed as extensions to existing reprocessing plants, although much work remains to be done to make these extensions compatible with industrial reprocessing practices. Many studies have demonstrated that fast-neutron-spectrum devices (dedicated fast reactor or accelerator-driven facilities) are more efficient than current light water reactors for recycling and transmuting long-lived radionuclides. A previous NEA study on advanced fuel cycles showed that the development of such cycles relies on new reactor designs which will require substantial, long-term R&D efforts and will likely take decades to implement. The scope of the present study and the fuel cycles assessed are introduced in the first two chapters. The waste categories used in this study and the secondary waste flows generated in different fuel cycle steps are presented in Chapter 3. In Chapter 4, the alternative fission product management options are described. The results of the HLW repository performance assessment calculations are presented in Chapter 5. The economic aspects of transmutation strategies are analysed in Chapter 6. Each technical chapter carries its own conclusions. The overall conclusions of the study are given in Chapter 7.
