Enriched uranium is a kind 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 2...

An overview of uranium enrichment methods. ... The earliest successful methods were electromagnetic isotope separation (EMIS), ... The first large-scale uranium enrichment facility, the Y-12 plant at Oak Ridge, Tennessee, used EMIS in devices called "calutrons." The process was abandoned in the United States because of its...

2. Uranium Enrichment and Depleted Uranium Basics: Science Since all isotopes of uranium have virtually the same chemical properties4, increasing the proportion of uranium in a sample depends on the difference in atomic weights of the isotopes (represented by the numbers 234, 235, and 238 attached to them).
