ABSTRACT OF THE DISCLOSURE: The invention is concerned with a pyroelectrothemical method for the reprocessing of irradiated nuclear fuels, characte- rized in that it comprises the steps of dissolving the nuclear fuel, containing fission products, in a bath comprising molten alkali metal sulfates; thermally decomposing the plutonium sul- fate Pu(SO4)2, formed in said molten bath to plutonium oxide, PuO2; electrodepositing uranium oxide, on the cathode of an elec- trolytic cell provided in said molten bath; recycling the melted sulfates of said molten bath to the start of the process; and conditioning said fission products and the said melted sulfates. The process according to the invention is more particularly usa- ble for a final disposal of said melted salts and fission products.
