Enriched uranium - Wikipedia

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2739–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7202%), and uranium-234 (234 U, 0.0050–0.0059%).Get price

Uranium Hexafluoride (UF6)

Uranium Hexafluoride and Its Properties. Uranium hexafluoride is a chemical compound consisting of one atom of uranium combined with six atoms of fluorine.

Uranium Enrichment | NRC.gov

CompositionUsesSafetyManagementOperationIndustryResearchTechnologyWhen uranium is mined, it consists of approximately 99.3% uranium-238 (U238), 0.7% uranium-235 (U235), and < 0.01% uranium-234 (U234). These are the different uranium isotopes. Isotopes of uranium contain 92 protons in the atomcenter or nucleus. (The number of protons in the nucleus is what makes the atoms \\"uranium.\\") The U238 atoms contain 146 neutrons, the U235 atoms contain 143 neutrons, and the U234 atoms contain only 142 neutrons. The total number of protons plus neutrons gives the atomic mass of each isotope that is 238, 235, or 234, respectively. On an atomic level, the size and weight of these isotopes are slightly different. This implies that with the right equipment and under the right conditions, the isotopes can be separated.Get price

Uranium Enrichment | Enrichment of uranium - World Nuclear

International Enrichment Centres, Multilateral ApproachesEnrichment ProcessesEnrichment of Depleted Uranium TailsEnvironmental IssuesNotes & ReferencesFollowing proposals from the International Atomic Energy Agency (IAEA) and Russia, and in connection with the US-led Global Nuclear Energy Partnership (GNEP), there are moves to establish international uranium enrichment centres. These are one kind of multilateral nuclear approaches (MNA) called for by IAEA. Part of the motivation for international centres is to bring all new enrichment capacity, and perhaps eventually all enrichment, under international control as a non-proliferation measure. Precisely what "control" means remains to be defined, and will not be uniform in all situations. But having ownership and operation shared among a number of countries at least means that there is a level of international scrutiny which is unlikely in a strictly government-owned and -operated national facility. The first of these international centres is the International Uranium Enrichment Centre (IUEC) at Angarsk in Siberia, with Kazakh, Armenian and Ukrainian equity so far. The centre is to...Get price
