FIELD: nuclear power engineering; weapon plutonium conversion. SUBSTANCE: for producing composite uranium-plutonium oxide fuel from recovered metal alloy of plutonium alloy ingredients are dissolved in molten mixture of alkali metal chlorides and uranyl when sparging melt with chlorine and stirring melt at a rate of 0.8-10 cm/s; mixed up oxides are settled down by melt electrolysis method and salts are separated from finely crushed chips of mixed up uranium and plutonium oxides. EFFECT: enhanced speed of alloy dissolution. 5 ex
