Uranium Enrichment 101
Naturally occurring uranium ore consists of -99% U-238
and just 0.711% of the fissile isotope U-235.
Enrichment is the process of raising the U-235
concentration to whatever level is required for a given
reactor (see graphic).
Enrichment is typically performed using advanced
centrifuges that separate the U-235 from the slightly
heavier U-238.

Enrichment is sold as Separative Work Units (SWU), which represent the effort needed to increase the
U-235 concentration. Higher enrichment levels require more SWU.
The SWU and natural uranium components of Low Enriched Uranium (LEU) can be, and often are,
bought and sold independently of one another. Centrus' LEU business segment principally sells SWU
but also sells modest quantities of natural uranium.View entire presentation
