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.

The vapor pressure of uranium hexafluoride, has been determined from 0 deg C to 85 deg C in a copper apparatus. The data obtained are given by the two equations log 10 P mm Hg = 2623.3/T + 10.8407 (solid, vapor), log 10 P mm Hg = -1505.9/T + 7.5223 (liquid, vapor) and the latent heats are: delta H sub sub = 12.00 kg-cal, delta H sub vap = 6.89 kg-cal. The experimental arrangement is shown in Figure 1. This consists of a reservoir A in a thermostat and a brass sylphon bellows for the measurement of pressure by a null method. The pressure above an atmosphere was read on a multiple mercury manometer using dibutylphthalate as a piston liquid. p2.
