FIELD: recovery of spent fuel.
SUBSTANCE: proposed method for recovering plutonium-containing sorbents of alkali metal fluorides is characterized in that sorbents are treated with water vapor or vapor-air mixture at temperature of 300 to 1000 °C. Hydrogen fluoride produced in the process is removed. After that plutonium dioxide is extracted from reaction products.
EFFECT: facilitated procedure, reduced cost.
