PLUTONIUM PROCESSING METHOD Russian patent published in 2001 - IPC

Abstract RU 2171306 C1

FIELD: nonferrous metallurgy. SUBSTANCE: plutonium is processed to give refined metal for production of power- destination reactor fuel. Processing includes two refining steps utilizing halide salt melts. In the first step, plutonium is treated with molten magnesium chloride at plutonium-to-magnesium chloride weight ratio (50- 100):1 and, in the second step, plutonium is subjected to anodic dissolution in halide melt to yield desired product on cathode. EFFECT: increased degree of removal of radiogenic and other elements with considerably reduced amount of radioactive wastes.
