Definition: Enriched uranium is a sample of uranium where the abundance of the isotope U-235 is increased above the natural abundance.

Examples: Nuclear reactors need U-235 to produce a controlled nuclear chain reaction. Natural uranium contains only 0.7% U-235. Nuclear reactor fuel is typically enriched to contain approximately 5% U-235.
