Uranium enrichment is the process of increasing the proportion of the fissile isotope uranium-235 (U-235) in natural uranium. Natural uranium contains about 0.7% U-235 and about 99.3% U-238. Enrichment raises the U-235 fraction to levels suitable for different uses, such as about 3–5% for most commercial light-water reactors, or much higher fractions for research reactors or certain装 naval propulsion concepts and, in some cases, weapons applications.
Technologies used for enrichment rely on the small mass difference between U-235 and U-238. The principal methods
Because enrichment is a dual-use capability with implications for nuclear proliferation, it is subject to international
Applications of enriched uranium include fuel for civil nuclear power reactors and certain research or medical
