REPROCESSING METHOD OF SPENT NUCLEAR FUEL AND REPROCESSING FACILITY OF SPENT NUCLEAR FUEL

摘要

PROBLEM TO BE SOLVED: To provide a spent nuclear fuel reprocessing method and so on capable of setting a fissile ratio of fissile radioactive isotope of a nuclear fuel substance included in a new nuclear fuel obtained after reprocessing to a target fissile ratio when reprocessing a plurality of sorts of different spent nuclear fuels in a single reprocessing facility.SOLUTION: The spent nuclear fuel reprocessing method for generating a new nuclear fuel by reprocessing a plurality of sorts of different spent nuclear fuels in the single reprocessing facility includes a mixing step for mixing a high fissile nuclear fuel with a high fissile ratio and a low fissile nuclear fuel with a low fissile ratio in an adjustment tank 23 so that the Pu fissile ratio of plutonium fissile radioactive isotope included in the nuclear fuel is set to the target Pu fissile ratio.
