WASHINGTON - Liquid Thermal Diffusion dissolves uranium hexafluoride (UF6) crystals into a column whose ends are kept at very different temperatures. UF6 molecules harboring the lighter uranium-235 (U-235) atoms diffuse slightly faster to the warmer side of the column than do those molecules with heavier uranium isotopes, mainly U-238, the lighter molecules collect at the warm side of the column. This U-235 enriched solution then becomes the starting fluid for the next iteration in a diffusion tube and so on. (U.S. Navy [Ref. 60834(H-300])
