Method for production of uranium dioxide particles from uranium hexafluoride by growing process in fluidized bed

Creators

Description

Processes of production and purification (necessary for fabricating fuel elements) of powdery uranium dioxide with particle size up to 1000 μm and more have been studied. Developed is continuous process of UO2 production with above particle size by converting uranium hexafloride into UO2 solid particles in fluidized bed while their interaction with water vapor and hydrogen on the uranium dioxide nucleus material. The method allows to conduct continuous selection from the apparatus of UO2 powder fraction with particle size near 1000 μm without nucleus material additional feed
