METHOD OF CONVERTING WASTE URANIUM HEXAFLUORIDE INTO URANIUM METAL Russian patent published in 2012 - IPC C01G43/06 C22B60/02

Abstract RU 2444475 C1

FIELD: chemistry.

SUBSTANCE: invention relates to ecology and is aimed at preventing environmental pollution and radiation poisoning. The method of converting waste uranium hexafluoride into uranium metal and calcium fluoride involves reaction of uranium hexafluoride and calcium metal, where gaseous uranium hexafluoride is fed into molten calcium metal by bubbling, and operating temperature is kept higher than the melting point of calcium fluoride.

EFFECT: invention enables conversion of toxic radioactive uranium hexafluoride into an non-volatile compact product which is safe for storage.
