Mathematical Modeling of Process of Obtaining the Solid Uranium Hexafluoride


Article Preview

A non-stationary mathematical model of desublimation UF6 in vertical tanks considers the movement of gaseous uranium hexafluoride contains in the article. Results of calculation of time dependence of the linear velocity desublimation, the thickness of the resulting layer of the solid phase, the temperature distribution in the tank wall - desublimation layer, filling dynamics of vertical tank B-12 by solid UF6 are presented. Calculations have shown that the 70% of B-12 tank is filled desublimation UF6 by 250 hours, which is in good agreement with the experimental data
