Abstract

PURPOSE: To obtain uranium trioxide with superior surface activity by decomposing uranyl nitrate in a specified temp. range in production of uranuim trioxide by thermal decomposition denitration of uranyl nitrate.
CONSTITUTION: Uranyl nitrate is thermally decomposed at 220W240°C to leave about 1W3% nitric acid and about 0.5W1% water in uranium trioxide formed. The decomposition can advantageously be carried out by an agitation furnace (e.g. screw furnace) method or a fluidized bed method. The resulting uranium trioxide particles have superior surface activity and can be used in production of uranium tetrafluoride or uranium dioxide pellets without requiring pretreatment.
