This study analyzes the nuclear fuel cycle when the partitioning and transmutation technology is introduced in the reprocessing of LWR spent fuel in the latter half of this century. In Japan, LWRs will continue to be used for power generation for the time being, and the treatment and disposal of uranium and plutonium spent fuel will be an issue. Assuming that the partitioning and transmutation of minor actinides becomes feasible in the reprocessing of these spent fuels in the middle of this century, it is shown that the burden of high-level waste disposal after that can be greatly reduced.
