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 ...
The Honeywell Uranium Hexafluoride Processing Facility, a uranium conversion facility, is located 1.9 miles (3 km) northwest of Metropolis, Illinois, United States. The plant, Honeywell Specialty Chemicals in Metropolis, Illinois, has a nominal capacity of 15,000 tU as uranium hexafluoride per year.
The US used to get most of its enriched uranium from Russia. Now scientists and companies are racing to produce it at home.
It's easy to lose track of nuclear news out of Oak Ridge. Here's why the Sept. 4 announcement was so different.
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 ...
A second method of laser separation is known as molecular laser isotope separation (MLIS). In this method, an infrared laser is directed at uranium hexafluoride gas (if enrichment of uranium is desired), exciting molecules that contain a U-235 atom.
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.
