uranium ore assay

  • Enriched uranium

    Enriched uranium is a type of uranium in which the percent composition of uranium 235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238 U isotope, with 235 U only constituting about 0.711% of its mass. 235 U is the only nuclide existing in nature (in any appreciable amount) that is fissile with
