{wiki=Enriched_uranium}
Enriched uranium refers to uranium in which the percentage of the isotope uranium-235 (U-235) has been increased compared to natural uranium. Natural uranium consists primarily of about 99.3% uranium-238 (U-238) and only about 0.7% U-235. Enrichment processes increase the proportion of U-235 to levels suitable for various applications, particularly nuclear power generation and weapons.
