Partitioning and transmutation strategy R&D for nuclear spent fuel: the SACSESS and GENIORS projects

In this context, and in the continuity of the FP7 EURATOM SACSESS project, GENIORS focuses on the reprocessing of MOX fuel containing minor actinides, taking into account safety issues under normal and mal-operation. | Partitioning and transmutation strategy R D for nuclear spent fuel the SACSESS and GENIORS projects EPJ Nuclear Sci.

Processes such as PUREX allow the recovery and reuse of the uranium and the plutonium of GEN II GEN III reactors and are being adapted for the recycling of the uranium and the plutonium of GEN IV MOX fuels. However it does not fix the sensitive issue of the long-term management of the high active nuclear waste HAW . Indeed only the recovery and the transmutation of the minor actinides can reduce this burden down to a few hundreds of years. In this context and in the continuity of the FP7 EURATOM SACSESS project GENIORS focuses on the reprocessing of MOX fuel containing minor actinides taking into account safety issues under normal and mal-operation. By implementing a three-step approach reinforcement of the scientific knowledge gt process development and testing gt system studies safety and integration GENIORS will provide more science-based strategies for nuclear fuel management in the EU. 1 Introduction plutonium mixed with depleted uranium from the stockpile. This reprocessing allows the saving of about The civilian use of the nuclear energy is more and more 20 of uranium from the mine but also reduces the time to discussed in terms of global and long-term environmental have a relative toxicity of the remaining ultimate waste impact. .
