Where Does Uranium Come From?

Enrichment increases the fissionable isotope, uranium-235 (U-235), within natural uranium from under 1 percent by weight to 3 to 5 percent. This allows the controlled chain reaction required for electricity generation. A fuel fabricator converts the enriched uranium hexafluoride into uranium dioxide powder and presses it into fuel pellets.
