Summary

Laboratory-scale dissolving tests have demonstrated that PuO/sub 2/, fired at temperatures between 950 and 1700/sup 0/C, can be dissolved at 25 to 35/sup 0/C to concentrations exceeding 100 g Pu/L in an electrochemical dissolver using silver ion as a redox catalyst. The dissolution rates are 2 to 5 times faster than the rates obtained using the current process (12 M HNO/sub 3/-0.18 M HF at 90/sup 0/C) and the corrosive fluoride ion is avoided. 4 refs., 5 figs., 1 tab.
