摘要：

The theoretical mechanism of the sublimation of uranium hexafluoride are considered. The most contribution to the rate of evaporation of UF6 is introduced by the conductive mode of heat exchange. Various modes of the intensification of the evaporation of uranium hexafluoride during the nitrogen supply in pulse mode to the product mass are investigated. The nitrogen supply results in the turbulization of gas flow within a vessel (Re = 2500-4000) and significantly increases the rate of evaporation of uranium hexafluoride with the substantial decrease in a weight of the nonevaporable residue of 5.6-1.0 kg. The complex application of the pulse nitrogen supply in combination with heating the bottom of the vessel is the most effective method for evaporating uranium hexafluoride. The rate of evaporation of UF6 increases by a factor of almost four in comparison with the design mode. The developed methods are applied in industry and provide the stable operation of Saturn reactors during the conversion of uranium hexafluoride into its dioxide.
