PROBLEM TO BE SOLVED: To provide a reprocessing method which makes it possible to easily remove a coated layer without carrying out many complicate processes in the recovery of nuclear fuel substances from a coated particle fuel. SOLUTION: This reprocessing method has a process 2 for crushing the coated particle fuel 1, a coated-layer-removal/uranium-recovery coincident electrolyzation process 3 in which the decomposition and removal of the coated layer, the dissolution of a fuel kernel and the precipitation and recovery of uranium dissolved in the molten salt are carried out at the same time through the molten salt electrolyzation of the crushed coated particle fuel at the anode and an actinide recovery electrolyzation process 4 for precipitating and recovering actinide elements remaining in the molten salt after the coated-layer-removal/uranium-recovery coincident eletrolyzation process 3 at the cathode through the molten salt electrolyzation.
