Uranium in which the U-235 isotope concentration has been increased to greater than the 0.711 percent U-235 (by weight) present in natural uranium.

Uranium in which the percentage of the fissionable isotope U-235 is increased beyond the content of 0.7205% in naturally occurring uranium. Various enrichment methods are possible: (see 'Diffusio [..]

Uranium in which the proportion of U-235 (to U-238) has been increased above the natural 0.7%. Reactor-grade uranium is usually enriched to about 3.5% U-235, weapons-grade uranium is more than 90% U-2 [..]

Uranium where the uranium-235 assay is above that of natural uranium. Enriched uranium product refers to enriched uranium resulting from the enrichment process, ie the process by which the assay of fe [..]

Uranium with an increased concentration of the isotope U-235. Natural uranium contains 0.7 percent U-235, whereas nuclear weapons typically require uranium enriched to 90 percent or more U-235. Nuclea [..]

Uranium with an increased concentration of the isotope U-235, relative to natural uranium. Natural uranium contains 0.7 percent U-235, whereas nuclear weapons typically require uranium enriched to ver [..]

Uranium in which the proportion of U-235 (to U-238) has been increased above the natural 0.7%. Reactor-grade uranium is usually enriched to about 3.5% U-235, weapons-grade uranium is more than 90% U-2 [..]

uranium in which the proportion of the isotope uranium-235 has been increased by removing uranium-238 mechanically. See also depleted uranium.

Uranium where the content U-235 is increased above its natural value of around 0.7% by weight. The enrichment process will also yield Depleted Uranium . Enriched Uranium is Fissile and can undergo nuc [..]

Uranium ore occurs naturally in a state that cannot be used in most reactors or to make nuclear weapons. Enriching the uranium makes it easier to use in reactors. The enrichment process increases the amount of the fissionable uranium-235 isotope. Uranium enriched to contain less than 20 percent uranium-235 is called low enriched uranium. Uranium en [..]
