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 ...
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%).
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.
In the first step, the S-50 uranium enrichment facility used the thermal diffusion process to enrich the uranium from 0.7% up to nearly 2% 235 U. This product was then fed into the gaseous diffusion process at the K-25 plant, the product of which was around 23% 235 U. Finally, this material was fed into calutrons at the Y-12.
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 ...
Recent satellite images show North Korea is expanding a uranium enrichment plant at its main Yongbyon nuclear complex, a sign that it’s intent on boosting the production of bomb materials ...
Natural uranium consists of three isotopes; the majority (99.274%) is U-238, while approximately 0.72% is U-235, fissile by thermal neutrons, and the remaining 0.0055% is U-234. If natural uranium is enriched to 3% U-235, it can be used as fuel for light water nuclear reactors. If it is enriched to 90% uranium-235, it can be used for nuclear ...
