Abstract
FIELD: processing of irradiated and rejected nuclear fuel. SUBSTANCE: invention refers to processing of mononitride uranium-plutonium fuel. Nitride is loaded into container and electrolyte carrying not less than 15.0% of uranium thrichloride by mass is used. Electrolyte is heated to temperature not below 600 C and current having density not more than 0.3 A/sq.cm is created on container and not more than 0.4 A/sq.cm - on electrode. Current with density not more than 0.1 A/sq.cm is formed across fusible electrode. Melt is heated to temperature not higher than 700 C. Fusible metal or alloy which is more electrically positive than uranium nitride is also placed into container with nitride fuel. This metal alloy is solved in container and uranium and plutonium are precipitated on fusible electrode - cathode. EFFECT: decomposition of mononitride fuel and transition of uranium, plutonium and actinides in the form of chlorides into electrolyte, reduction and extraction of metallic uranium and plutonium, recovery of fission products from nuclear fuel.
