Dry-ADU process for UO2 production

  • 1. Div. of Chemical Engineering, Inst. of Nuclear Energy Research, Lung-Tan (Taiwan)

Description

Scattered granular ammonium diuranate (ADU) products were prepared directly by reacting atomized liquid droplets of uranyl fluoride or uranyl nitrate with ammonia gas. After calcination in nitrogen and reduction with the steam-hydrogen gas, the ADU products were converted to UO2 powders which were pelletized and then sintered for characterization. No waste liquid filtrate was generated in the process. The ADU product and UO2 powder were easy-handling. Uranium dioxide powders with low fluorine content and good pelletizing and sintering properties were prepared. (orig.)
