PROCESS FOR THE REDUCTION OF PLUTONIUM
Patent
·
OSTI ID:4842838
In a known process for separating Pu from irradiated U, the mixture is dissolved in HNO/sub 3/, Pu(IV) and U(VI) nitrates are extracted by tributyl phosphate, and Pu(IV) is reduced to Pu(III) prior to back extraction with an aqueous solution. The reducing agent commonly used either is too slow (hydrazine or hydroxylamine) or results in the addition of Fe to Pu (ferrous compounds). These disadvantages can be avoided by using ascorbic acid, which effects rapid reduction of Pu(IV) even in the presence of HNO/sub 3/. (D.L.C.)
