Uranium Enrichment | NRC.gov

2020-12-2 · The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.
