Enriched uranium Wikipedia

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2739–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7202%), and uranium-234 (234 U, 0.0050–0.0059%).

NRC: Uranium Enrichment

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.
