Abstract
The possibility of preliminary reduction of U3O8 with hydrogen and ammonia before its fluorination for the purpose of increasing uranium (IV) content in the product is considered. Results of the investigation aimed at the determinaiton of optimal temperatures and the kinetics of U3O8 reduction under non-isothermic conditions by means of temperature-programmed reduction are presented.
