235U isotope separation methods

The foregoing discussion fairly well demonstrates that on a small scale any desired Isotope can be separated either by the electromagnetic or the thermal diffusion method. In contrast to these laboratory-scale processes, the separations of the heavier Isotope D, of the lightest element, hydrogen, and of the lighter Isotope 235u, of the heaviest natural element uranium, are carried out on a literally enormous Industrial scale.
