Dynamics of UF[6] Desublimation with the Influence of Tank Geometry for Various Coolant Temperature

Mathematical model of UF[6] desublimation in a vertical immersion tank is presented in the article. Results of calculations of the filling dynamics of the tanks with 1m3 volume at various coolant temperatures, with and without ellipticity of the end walls are given. It is shown that allowance for the ellipticity of the end walls of the tanks leads to a significant increase in the time of desublimation of UF[6]

Influence of changing feed flow value on germanium isotope separation in gas centrifuge cascade

Modeling of a nonstationary process caused by changing the cascade feed flow value using germanium isotope separation as an example. During a nonstationary process, the concentrations of isotopes with intermediary mass number in light and heavy fraction flows may cross the range limits restricted by the initial and final stationary values and exceed the maximum reachable values for a three-flow cascade. Time for stationary isotope concentrations to settle is different for isotopes and depends on the final values of cascade flow
