Photochemical separation of actinides in the Purex process
Description
Photo-redox reactions of MO22+ and M4+ (where M is plutonium or uranium) in aqueous acid solutions containing hydrazine, ethanol, or formic acid reductants are briefly reviewed. These reactions suggest that Pu4+ can be separated from UO22+ and NpO22+ by a photoreductive reaction using hydrazine as the reductant. Hydrazine by itself is too slow a reductant, but illumination with 1 W of 300 nm UV radiation increases the hydrazine rate of reduction at least six-fold and produces an 18-fold increase in the Pu-O separation factor in a non-optimized laboratory-scale system
