Book Description
Spray fluorination may be used to recover uranium as the volatile hexafluoride from molten fluorides by spraying the salt into a fluorine atmosphere. This drop-wise liquid fused-salt fluoride volatility process applied to zirconium-matrix fuels, with the possible advantage of avoiding corrosive conditions involved in sparging. Experimental equipment was developed and tests were made for heat and mass transfer. From the data obtained, process design calculations indicated that a satisfactory equipment design is possible.

Book Description
A preliminary chemical flowsheet is presented of a fluoride volatility process for recovering and decontaminating U from heterogeneous reactor fuels after dissolution in a fused salt. In laboratory work, a gross BETA decontamination factor of>10/sup 4/ was obtained in the fluorination of a UF/sub 4/-- NaF-- Zr F/sub 4/ melt by passing the product UF/sub 6/ through NaF at 650 deg C. The solubility of UF/sub 6/ in molten NaF--ZrF/sub 4/ was shown in kinetic studies to cause a lag in the evolution of UF/sub 6/ from the fluorinator. Corrosion of nickel in the fluorination step appeared to be 2 to 4 mils/hr during the time that U was present. The average corrosion rate over the process as a whole yvas less than 0.4 mil/hr. (auth).
