摘要

In France, the current management of spent fuels consists in their processing and in recycling the interim Plutonium inform of MOX fuel in 20 PWRs (900 MWe). This management enables reducing the storage capacity for the spent fuels, and reducing the quantity and radiotoxicity of ultimate waste, presently consisting of fission products and minor actinides solidified in the form of highly resistant long-lasting glass matrices. In the perspective of possibly eliminating in the future the minor actinides, that represent the long-life radiotoxic component of today's vitrified waste, a basic and physically optimal scenario is presented, which foresees the partitioning of those minor actinides and their recycling in the 4th generation fast neutron systems, having the intrinsic capability of fissioning all the actinides. This paper presents analysis of the transition between the current fuel cycle of PWRs, which consists in a single stage of Plutonium recycling, and that of the 4th generation systems which comprise multiple recycling of all the actinides: Uranium, Plutonium and Minor Actinides. Following a physical analysis of the respective potential of the fast neutron or thermal neutron spectra for transmutation, we examine, based on the same set of assumptions, the consequences of the date of deployment of the 4th generation systems and the merits of the scenarios for the temporary recycling in PWR of Plutonium waiting the global recycle of all of the actinides in the 4th generation systems. In the perspective of the deployment of a first series of 4th generation systems in 2030-2040, a global actinide management for the back end of the PWR cycle is considered, including the partitioning of the minor actinides. If ever the deployment of the 4th generation systems would be postponed, the aforementioned strategy would still be possible and extremely advantageous due to the capability of fast neutron systems to recycle the transuranium elements (Plutonium and minor actinides) produced by the PWRs during the 21st century.
