The plutonium solution may be obtained from a reprocessing plant solution by addition of hydrogen peroxide or by autoradiolysis. The nitrate concentration of the final solution may be slightly greater than, equal to, or less than that required for U(VI) and Pu(IV) valencies. The solution may be used for the preparation of mixed U and Pu oxides by the gel process or by thermal dinitration or for the co - precipitation of hydroxides or oxalates.
