Uranium in which the content of the isotope uranium-235 has been increased above its natural value of 0.7% by weight. Typical low-enriched uranium for commercial power reactors is enriched in uranium-235 to the range of 3% to 5%. In highly enriched uranium, the uranium-235 has been increased to 20% or more.
uranium in which the naturally occurring proportion of uranium which can be readily split (fission ) is increased. For use as fuel in a nuclear power plant, it is increased from less than 1 percent to between 3-5 percent. To produce an atomic bomb requires enrichment to 90 percent.
Uranium in which the proportion of uranium 235 to total uranium of all isotopes is increased from 0.72% to a higher value.
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 concentration of the fissionable isotope, Uranium-235, has been increased beyond the 0.7% level found in natural uranium.

uranium in which the only fissile isotope, the 235 isotope, has been increased from its naturally occurring low level (0.72% by mass) to a concentration of 3.5%, for example, for a fuel intended for use in a pressurized-water reactor
238U enriched with fissionable 235U which is then used to fuel nuclear reactors.
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. Nuclear power plant fuel typically uses uranium enriched to 3 to 5 percent U-235, material that is not sufficiently enriched to be used for nuclear weapons.
Uranium in which the content of the isotope Uranium-235 has been increased from its natural state.
uranium in which the proportion of the isotope uranium-235 has been increased by removing uranium-238 mechanically. See also depleted uranium.
Uranium in which the proportion of uranium-235 (to uranium-238) has been increased above the natural 0.7 percent uranium-235. Reactor-grade uranium is usually enriched to three to five percent uranium-235. Uranium can be fabricated into nuclear fuel and fissioned in nuclear reactor to produce energy.
Uranium in which the naturally occurring proportion of uranium that can be readily split (fission) is increased. For use as fuel in a nuclear power plant, it is increased from less than one percent to between three and five percent. An atomic bomb requires enrichment to 90 percent.
Uranium that has greater amounts of the isotope uranium-235 than occur naturally. Naturally occurring uranium is nominally 0.720 percent uranium-235.
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-235.
Enriched uranium is uranium whose uranium-235 content has been increased through the process of isotope separation. Natural uranium consists mostly of the 238U isotope, with about 0.72 % by weight as 235U, the only isotope existing in nature in any appreciable amount that is fissionable by thermal neutrons.
