<em>Uranium isotope is a widely used fuel source. It is enriched artificially up to 3-5% from its natural state. </em>
It is a commercial process where the uranium oxide is done some conversion with chemical processing to form the uranium hexafluoride (UF6), to make it useable for the enrichment facilities.
This <em>processing of the uranium from 0.7% to 5% enrichment by isotope separation</em> is used as a nuclear fuel which is very useful for the commercial purpose.
