Abstract
1,260,562. Uranyl fluoride. UNITED NUCLEAR CORP. 31 July, 1969, No. 38454/69. Heading C1A. Uranyl fluoride is prepared by introducing steam and gaseous UF 6 separately into a reaction zone containing fluidized uranyl fluoride particles, the UF 6 being introduced at at least 200‹ F. and 5000 c.f.h. per square inch of nozzle opening to prevent the formation of uranium fluoride solids prior to its hydrolysis with the steam, regulating the relative concentration of the UF 6 and steam in the reaction zone so that the amount of steam is above, but not in excess of 300% of, the stoichiometric requirement for the hydrolysis while maintaining the temperature in the reaction zone above 500‹ F. but below 900‹ F., maintaining sufficient uranyl fluoride seed particles in the zone to stabilize the average particle size therein and removing excess uranyl fluoride particles from the reaction zone. The hydrolysis may be carried out in the presence of an inert gaseous diluent, e.g. N 2 , CO 2 which may be used as a carrier for the gaseous UF 6 or to fluidize the bed either alone or in combination with the steam used for the hydrolysis.
