A continuous method for the production of uranium trioxide from uranyl nitrate solution was developed, and its advantages over the batch process pointed out. Uranyl nitrate and fluidizing air are sprayed into the reactor, heat being supplied by molten heat transfer salt. The UO/sub 3/ product overflows from the reactor into a packaging station. The best range of temperatures was found to be 600 to 800 deg F. Production rates of 50 to 150 lb UO/sub 3/ per hour were attained; at rates higher than 150 lb/hr, uranyl nitrate clogged the off-gas system. The product was granular 99.0% UO/sub 3/ and had a high bulk density, 3.5 to 4.3 g/cm/sup 3/. Operating conditions, e.g., temperature, were found to have a pronounced effect on particle size.
