Highly enriched uranium definition
Did you know?
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. WebWeapons-grade uranium. Natural uranium is made weapons-grade through isotopic enrichment. Initially only about 0.7% of it is fissile U-235, with the rest being almost …
WebIt says further that India may be producing significant quantities of highly enriched uranium at its gas-centrifuge plant in Trombay, outside Mumbai, and adds that the amounts involved remain unknown. The most striking feature of India's weapons program after the Pokhran nuclear tests of May 1998, the report says, is its 'moderate pace'. WebHighly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. [citation needed] U-233 is produced from thorium-232 by neutron capture. The U-233 produced thus does not require enrichment and can be relatively easily chemically separated from residual Th-232.
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. WebJan 27, 2024 · : a light isotope of uranium of mass number 235 that constitutes less than one percent of natural uranium, that when bombarded with slow neutrons undergoes rapid fission into smaller atoms with the release of neutrons and energy, and that is used in nuclear reactors and atomic bombs Example Sentences
