METHOD OF URANIUM HEXAFLUORIDE PRODUCTION

摘要

FIELD: chemistry. ^ SUBSTANCE: invention can be used in nuclear technology. Uranium oxides with valency from +4 to +6 undergo the reaction with hydrogen fluoride forming the intermediate containing 4080 wt % of uranylfluoride or uranium tetrafluoride, the rest is initial products. Then obtained intermediate product is directed to flame reactor for fluorination by elemental fluorine taken in the excess 57 %. The obtained uranium hexafluoride is separated from gas phase by desublimation. The fluorine-containing products remaining in the gas phase after desublimation are taken for entrapment by the initial uranium oxides. ^ EFFECT: invention allows to enhance the process efficiency and obtain uranium hexafluoride of 99,9% purity. ^ 1 tbl
