URANIUM HEXAFLUORIDE PROCESSING METHOD Russian patent published in 2007 - IPC C01G43/06

Abstract RU 2311346 C1

FIELD: industrial inorganic synthesis.

SUBSTANCE: invention relates to technology of processing exhausted (wasted) uranium hexafluoride into uranium fluoride. Method envisages hydrolysis of solid uranium hexafluoride with aqueous hydrogen fluoride solution at 20-30°C and excessive pressure up to 100 kPa in closed space of rotating reactor.

EFFECT: completely eliminated uranium hexafluoride and hydrogen fluoride gas loss as well as environmental exposure to extremely volatile and dangerous substances.
