The use of dioxygen difluoride (FOOF) and KrF/sub 2/ for the recovery of Pu from lean residues by conversion to gaseous PuF/sub 6/ is being investigated. The greater stability of PuF/sub 6/ at room temperature allows much more extensive removal of Pu from contaminated wastes, when compared to the high temperature fluoride volatility process. The process also requires fewer additive chemicals than aqueous processes, thus minimizing the amount of material that must be disposed of as radioactive waste. The transportability of gaseous PuF/sub 6/ allows much of the process to be automated, reducing operator exposure to radiation. Removal of PuF/sub 6/ decomposition product is easily facilitated by the use of these fluorinating agents. 9 refs., 8 figs.
