REPROCESSING SYSTEM AND REPROCESSING METHOD OF SPENT NUCLEAR FUEL

摘要

PROBLEM TO BE SOLVED: To provide a reprocessing system and reprocessing method of a spent nuclear fuel capable of increasing the plutonium enrichment of a nuclear fuel without reducing the nuclear diffusion resistance.SOLUTION: The reprocessing system of a spent nuclear fuel extracted from a nuclear reactor includes: separating means for separating uranium from a nitric acid solution in which the spent nuclear fuel is dissolved and obtaining plutonium nitrate solution; and mixing means for mixing an inactive base material to the plutonium nitrate solution that is fed from the separating means to manufacturing means of a nuclear fuel by a sol-gel method.
