Radiolysis of 232,234U-Enriched Regenerated-Uranium Hexafluoride at the Temporary Storage Stage in a Separation Plant

The results of modeling of the radiolysis of uranium hexafluoride at the stage of its temporary storage in a separation plant are reported. Regenerated uranium, which is enriched with 232,234U, being the strongest α-emitting isotopes, was examined as an example. The radiochemical yield of UF6 decomposition was determined approximately from the experimental data. It is shown that the concentration of uranium pentafluoride formed upon radiolysis of uranium hexafluoride is a factor of 107 lower, which, neglecting impurities, makes it possible to assume that the hexafluoride as a whole retains its properties.
