natural uranium, but light water reactors must use low enriched uranium because of the higher neutron absorption of light water. Uranium enrichment removes...

separating natural uranium into enriched uranium and depleted uranium is the largest application. In the following text, mainly uranium enrichment is considered...

enriching is downblending. Surplus highly enriched uranium can be downblended with depleted uranium or natural uranium to turn it into low-enriched uranium...

natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has...

The Prohibiting Russian Uranium Imports Act (H.R. 1042) is a U.S. law enacted on May 13, 2024, banning low-enriched uranium imports from Russia. Approved...

converted by heating with hydrogen to form UO2. It can be made from enriched uranium hexafluoride by reacting with ammonia to form a solid called ammonium...

use uranium enriched to 3–5% U-235, the only fissile isotope that is found in significant quantity in nature. One alternative to this low-enriched uranium...

low-enriched uranium, and did not produce highly enriched uranium until 1954. By 1957 it was capable of producing 125 kg of highly enriched uranium per...

uranium enriched to 89% was delivered to Los Alamos by July 1945. The entire 50 kg, along with some 50%-enriched, averaging out to about 85% enriched...

(medium-enriched uranium). Stocks in excess of 300 kg enriched up to 3.67% would be diluted to 0.7% or sold in return for uranium ore, while uranium enriched...

emission. Enriched uranium contains more 234U than natural uranium as a byproduct of the uranium enrichment process aimed at obtaining uranium-235, which...

neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure...

IAEA and Kazakhstan signed an agreement to host the world's first Low Enriched Uranium Bank in the Ulba Metallurgical Plant located in Oskemen. Active since...
