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 99.2732–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7210%), and uranium-234 (234 U, 0.0049–0.0059%).
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 entirely uranium-238 (U-238). They are separated by their differing masses. Highly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. [citation needed]
Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
By tonnage, separating natural uranium into enriched uranium and depleted uranium is the largest application. In the following text, mainly uranium enrichment is considered. This process is crucial in the manufacture of uranium fuel for nuclear power plants and is also required for the creation of uranium-based nuclear weapons (unless uranium ...
VIENNA/WASHINGTON (Reuters) -Iran has begun the process of producing enriched uranium metal, the U.N. atomic watchdog said on Tuesday, a move that could help it develop a nuclear weapon and that ...
Between 2011 and 2012, GLE applied for and received a permit to build a commercial enrichment plant at Wilmington. [10] [11] The plant would enrich uranium to 8% 235 U, the upper end of low-enriched uranium. [12] In 2014, both GLE and Silex Systems restructured, with Silex halving its workforce. [13]
Uranium enrichment is getting underway this week at a facility in southern Ohio, a federally authorized demonstration project considered critical to produce the type of fuel needed for newer, more ...
Orano announced to the public on Sept. 4 that it will make the largest single investment in Tennessee history to build a multibillion-dollar uranium enrichment facility in Oak Ridge, on land that ...
