AbstractAbstract
[en] PuO2-containing solids, particularly residues from incomplete HNO3 dissolution of irradiated nuclear fuels were dissolved in aqueous HI. The resulting solution was evaporateed to dryness and the solids were dissolved in HNO3 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
