The mathematical model and results of numerical calculations of sedimentation tank cooling upon desublimation of the flow of $\mathrm{UF}_6$ and light impurities

A physico-mathematical model of sedimentation tank cooling (ST) with cold air for desublimation of a flow of uranium hexafluoride with admixtures of hydrogen fluoride is presented. The model is based on gas dynamics equations written for a ramified network of pipelines. The simulation results for different operating modes of the sedimentation tanks are presented. It is shown that technical characteristics of the VKhM 0.54/0.6 air-cooling machine are sufficient to provide for the technological process of uranium hexafluoride and hydrogen fluoride desublimation in sedimentation tanks.
