Uranium peroxide in the form of spherical particles having good flowability and processes for preparing same
A process is claimed for preparing uranium peroxide in a fluidized bed by precipitation of a uranium peroxide solution obtained from the reaction of uranyl sulfate or uranyl nitrate solutions having a concentration of uranium between about 0.5 and 300 g/L and a hydrogen peroxide solution having a concentration of from about 5 to about 70% by weight at a pH of from about 2.5 to about 4 and a temperature of from about 0/sup 0/ to about 60/sup 0/ C. The easily handled uranium peroxide product so produced are characterized by their substantially spherical form, their mean diameter of from about 30 to about 130 microns, their untamped bulk density of about 1.9 to about 2 g/cm/sup 3/, and Carr scale flowability of at least 95, with a sodium ion content below 300 ppm such uranium peroxides are useful intermediates for producing nuclear fuel with great safety of manipulation and low sodium content.
