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.

2021年1月4日 · This work describes a streamlined approach to the recovery and purification of 234U from aged 238Pu. Key modifications to conventional techniques are described that result …

When natural uranium has been chemically purified, or otherwise separated from the ore, it consists of three nuclides: U-238, U-234 and U-235. By mass, it is almost all U-238. B y acti vit …

purification is accomplished by a solvent extraction process. The other facility, the Enriched Uranium Laboratory (LUE, Laboratorio de Uranio Enriquecido) produces 90% enriched …
