PuO/sub 2/-containing solids, particularly residues from incomplete HNO/sub 3/ dissolution of irradiated nuclear fuels were dissolved in aqueous HI. The resulting solution was evaporateed to dryness and the solids were dissolved in HNO/sub 3/ for further chemical reprocessing. Alternatively, the HI solution containing dissolved Pu values, can be contacted with a cation exchange resin causing the Pu values to load the resin. The Pu values were selectively eluted from the resin with more concentrated HI.
