Pyroelectrochemical process for reprocessing irradiated nuclear fuels

摘要

In a method for reprocessing irradiated nuclear fuels, the fuel to be reprocessed is dissolved in a fused-salt bath while absolute sulfuric acid is added dropwise to said bath, plutonium sulfate is thermally converted into the corresponding oxide, the uranium oxide is electrolytically deposited from the fused-salt bath as the electrolyte, the melted salts are recycled to the starting end of the process and the fission products and the melted salts are conditioned for final disposal.
