RECOVERY OF PuF$sub 6$ BY FLUORINATION OF FUSED FLUORIDE SALTS
Fused salt fluorination tests were conducted at 600 deg C to determine the feasibility of recovering plutonium as PuF/sub 6/ in the fused salt-fluoride volatility process. Recoveries and material balances were good, although the initial plutonium concentration in 50-50 mole% NaF -- ZrF/sub 4/ or 3l-2445 mole% LiF-- NaF-- ZrF/sub 4/ salt was only 2 ppm. The volatilization reaction appeared to be approximately first-order with espect to the plutonium concentration in the salt. Results of absorption of the volatilization PuF/sub 6/ on beds of LiF, CaF/ sub 2/, or NaF indicate that this is a possible method of trapping the material in fluoride volatility processes, possibly separately from UF/sub 6/.
