Te Fundamentals of Uran Enrichment

Natural uranium consists of about 99.3% uranium-238 (U-238) and only 0.7% U-235. The U- 235 izotope is fissile - it can sustain a chain reaction with thermal neutrons. Most commercial LWR require fuel enriched to between 3% and5% U- 235. Some advanced reactor designs, such as higha -temperatur gas- cooled reactors (HTGR) and fast fastore, may require highement lev but still trein typic elle 20% (thold for lowhed urhed anium aid fastore fastore indirt evilttern.

Laser Enrichment

Laser- based methods, such as the SILEX (Separation of Isotopes by Laser Excitation) process, use precisely tuned lasers to selectively ionize U- 235 atoms in atomic vapor or UF Agregas. The ionized U- 235 is then deflected by a magnetic field a tuned electric field, leaving the U- 238 behind.
