INFLUENCE OF THE INLET-VALVE DIAMETER AND THE TEMPERATURE OF GASEOUS UF6 ON THE DYNAMICS OF FILLING OF TANKS WITH SMOOTH INTERIOR WALLS WITH DESUBLIMATED UF6

In the article, the authors have presented a software-implemented and verifi ed mathematical model of the process of desublimation of UF6 into vertical immersion tanks. Results of calculating the time of fi lling and the average performance of the tanks of volume 1.0, 2.0, 2.5, 3.0, and 4.0 m3 with smooth interior walls upon the change in the diameter of the inlet valve and in the temperature of gaseous UF6 in the collector have been given. It has been shown that the decrease in the gaseous-UF6 temperature from 40 to 10o C makes it possible to increase the tank′s average performance by 7.0–7.4%. The increase in the inlet-valve diameter from 5·10–3 to 65·10–3 m leads to an increase of 76.0–88.0% in the average performance of the tanks.
