uranium enrichment


  • The process of increasing the abundance in uranium of the fissile isotope uranium-235, typically to make it suitable for use in nuclear power or nuclear weapons; frequently attributive.

    Natural uranium is made up of about 0.72% uranium-235. Enriched uranium used in nuclear power generation typically contains 3–5% uranium-235; that used in nuclear weapons typically contains over 85% uranium-235.
