CHART OF THE NUCLIDESDOE-HDBK-1019/1-93Atomic and Nuclear PhysicsIn the case of uranium, the natural uranium ore is 0.72 a/o uranium-235. The desired outcomeof the enrichment process is to produce enriched uranium. Enriched uranium is defined asuranium in which the isotope uranium-235 has a concentration greater than its natural value. Theenrichment process will also result in the byproduct of depleted uranium. Depleted uranium isdefined as uranium in which the isotope uranium-235 has a concentration less than its naturalvalue. Although depleted uranium is referred to as a by-product of the enrichment process, itdoes have uses in the nuclear field and in commercial and defense industries.SummaryThe important information in this chapter is summarized below.Chart of the Nuclides SummaryEnriched uranium is uranium in which the isotope uranium-235 has aconcentration greater than its natural value of 0.7%.Depleted uranium is uranium in which the isotope uranium-235 has aconcentration less than its natural value of 0.7%.NP-01Page 16Rev. 0
