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

Resumo

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.
