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%).
Compared to current enrichment technologies, SILEX obtains a higher enrichment. Hence fewer stages are necessary to reach bomb grade uranium (> 90% 235 U). According to GLE, each stage requires as little as 25% of the space of the conventional methods. Hence it would facilitate to rogue governments to hide a production facility for bomb uranium ...
Other methods of separation were more practical at that time, but this method was designed and used in South Africa for producing reactor fuel with a uranium-235 content of around 3–5%, and 80–93% enriched uranium for use in nuclear weapons.
It's easy to lose track of nuclear news out of Oak Ridge. Here's why the Sept. 4 announcement was so different.
The US used to get most of its enriched uranium from Russia. Now scientists and companies are racing to produce it at home. The US is dismantling nuclear warheads to power the next generation of ...
Due to the high energy consumption, enrichment of uranium by diffusion was gradually replaced by more efficient methods. The last diffusion plant closed in 2013. [ 4 ] The Paducah Gaseous Diffusion Plant was a US government effort to generate highly enriched uranium to power military reactors and create nuclear bombs which led to the ...
Orano, the France-based parent company of Orano USA, is a world leader in the nuclear fuel supply chain, from its uranium mines in Canada, Kazakhstan and Niger, to its methods of recycling used ...
Atomic vapor laser isotope separation, or AVLIS, is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions. [ 1 ] [ 2 ] A similar technology, using molecules instead of atoms, is molecular laser isotope separation (MLIS).
