TRU recycling options for environmentally friendly and proliferation-resistant nuclear fuel cycle of FBR

Permana, S.; Suzuki, Mitsutoshi

Fast reactor technology becomes more important player to enhance the optimum fuel utilization as well as for minimizing spent fuel waste such as trans-uranium by adopting closed fuel cycle option. The embodied challenges for introducing closed fuel cycle are proliferation resistance (PR) aspect of nuclear fuel as well as utilizing advanced fuel reprocessing and fabrication facilities. High level of PR for future nuclear fuel cycles have to be considered which can be obtained from isotopic material barriers such as uranium isotopic barrier, neptunium, and plutonium and so on.
