• "Fluorine is used in the nuclear industries of many countries to make uranium hexafluoride for enrichment of uranium in the fissile ²³⁵U isotope...Repeated diffusion of UF₆ (g) through porous plugs (or centrifugation of the vapor) concentrates ²³⁵UF₆ relative to ²³⁸UF₆, since the speed of diffusion varies inversely as the square root of the molecular mass. This enrichment is not needed for fueling power reactors with good neutron economy, such as the Canadian CANDU system. Gaseous diffusion plants for UF₆ are expensive, not least because UF₆ is itself an aggressive fluorinating agent and thus must be contained in special fluorine-resistant materials." 1
