METHOD FOR DYNAMIC GASIFICATION OF URANIUM DEPOSITS Russian patent published in 2016 - IPC C01G43/06 C01B7/20

Abstract RU 2588241 C1

FIELD: nuclear engineering.

SUBSTANCE: invention relates to nuclear engineering and chemical industry and can be used for cleaning and recovery of metal surfaces of installations intended for separation of uranium isotopes. Method involves successive circulation of gas mixture containing ClF₃ and F₂ in weight ratio (1.5÷3.5): 1, through deposition of uranium and a layer of sodium fluoride, heated to 190-220 °C.

EFFECT: invention increases efficiency of fluorination, reduces consumption of ClF₃, increases degree of return UF₆ in separation stage and reduces period of return UF₆ in separation process.
