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%).
Factorio is a construction and management simulation game developed and published by Czech studio Wube Software. The game was announced via an Indiegogo crowdfunding campaign in 2013 and released for Windows , macOS , and Linux on 14 August 2020 following an early access phase, which was made available on 25 February 2016.
Infrared absorption spectra of the two UF 6 isotopes at 300 and 80 K. Schematic of a stage of an isotope separation plant for uranium enrichment with laser. An infrared laser with a wavelength of approx. 16 μm radiates at a high repetition rate onto a UF6 carrier gas mixture, which flows supersonically out of a laval nozzle.
Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).
The only other such facility in the United States, the Portsmouth Gaseous Diffusion Plant in Ohio, ceased enrichment activities in 2001. [ 5 ] [ 16 ] [ 17 ] Since 2010, the Ohio site is now used mainly by AREVA , a French conglomerate , for the conversion of depleted UF 6 to uranium oxide .
The Urenco Group is a British-German-Dutch nuclear fuel consortium operating several uranium enrichment plants in Germany, the Netherlands, United States, and United Kingdom. [1] It supplies nuclear power stations in about 15 countries, and states that it had a 29% share of the global market for enrichment services in 2011.
The National Enrichment Facility (NEF) is a nuclear facility for the enrichment of uranium associated with the Los Alamos National Laboratory. The plant uses a gas centrifuge technology known as Zippe-type centrifuges. It is located 5 miles (8.0 km) east of Eunice, New Mexico. [1]
Laser enrichment experiments were carried out there, however, the plant has been shut down since Iran declared it has no intentions of enriching uranium using the laser isotope separation technique. [38] In September 2006, Alireza Jafarzadeh claimed that the site has been revived by Iran and that laser enrichment has been taking place at this site.
