Method of fabrication of uranium oxide UO/sub 2/ by the dry processing route and a device for the practical application of the method
Patent
·
OSTI ID:6525646
In a first step, uranium hexafluoride gas is reacted with steam in a first region of a vessel. In a second step, the oxyfluoride UO/sub 2/F/sub 2/ obtained in the first step is converted to UO/sub 2/ in a two-stage reduction process in which it is first contacted with a mixture of hydrogen gas and steam in one zone of the second region of the vessel, then contacted with the hydrogen gas in another zone of the second region.
