Abstract
Deactivation and processing of the man-caused wastes of molybdenum from the production of uranium dioxide by means of fluorination with elemental fluorine were studied. The level and depth of molybdenum contamination with radioactive substances were established, the major physicochemical parameters of molybdenum fluorination were determined: the equilibrium composition, duration and conditions of reaction. The apparent activation energies were determined, and kinetic equations were deduced.
