Method for dissolving plutonium oxide

Patent ·
OSTI ID:7072975
; ;
PuO/sub 2/-containing solids, particularly residues from incomplete HNO/sub 3/ dissolution of irradiated nuclear fuels, are dissolved in aqueous HI. The resulting solution is evaporated to dryness and the solids are 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 are selectively eluted from the resin with more conventrated HI.
