Isotope separation — is the process of concentrating specific isotopes of a chemical element by removing other isotopes, for example separating natural uranium into enriched uranium and depleted uranium. This is a crucial process in the manufacture of uranium fuel… … Wikipedia
Gaseous diffusion — is a technology used to produce enriched uranium by forcing gaseous uranium hexafluoride, UF6, through semi permeable membranes. This produces a slight separation between the molecules containing uranium 235 and uranium 238. By use of a large… … Wikipedia
