Uranium (Nuclear) - need

Because less than one percent of uranium ore contains uranium-235, the form used for energy production, uranium must be processed to increase its concentration. This process—called enrichment—increases the percentage of uranium-235 from 0.7 to three to five percent, the percentage required for reactor fuel. It typically takes place at a gaseous
