A method for producing uranium hexafluoride by fluorination of crude uranium tetrafluoride is described. lnstead of removing metallic impurities from the ore concentrate by solvent extraction before reduction, the concentrate is reduced directly and impurities are removed at differeat points in the processing, mainly from the fluorinator. Distillation of volatile impurities from the crude uranium hexafluoride completes the purification. Because of their known efficiency in gassolid-type reactions, fluidized-bed reactors are used. A schematic of the pilot-plant fluid-bed fluorinator is shown. The fluorinator consists of three systems: gasmetering, reactor, and condensing. (j.H.M.)
