WebEnriched uranium: 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. Enrichment: Physical process of increasing the proportion of U-235 to U-238. See also SWU.

Webhighly enriched uranium or "HEU" means the equivalent (in terms of uranium and enrichment content) of 50 metric tons of uranium with an average Assay of approximately forty percent (40%) as either metal (hollow cylinders, broken or sheared pieces, and other small pieces) or oxide (either UO (3) or U (3)O (8). Sample 1 Based on 1 documents Save Copy WebThis small mass difference allows the isotopes to be separated and makes it possible to increase (enrich) the percentage of U-235 in uranium.

The isotope 235 U is used to manufacture nuclear fuel rods … WebThe claim has long been made that the development and expansion of commercial nuclear power led to nuclear weapons proliferation, because elements of the nuclear fuel cycle (including uranium enrichment and spent-fuel reprocessing) can also serve as pathways to weapons development. WebHighly-enriched uranium (HEU – >20% U-235) allowed more compact cores, with high neutron fluxes and also longer times between refuelling. Therefore many reactors up to the late 1970s used it, and most state-of-the-art reactors had 93% enriched fuel. poor acting
