1
Uranium Mining and Milling
Uranium ore is extracted, purified and milled by miners to become uranium oxide (U3O8) or Yellowcake
2
Uranium Conversion
U3O8 is chemically converted into uranium hexafluoride (UF6), also known as natural uranium feed, and transported to enrichment facilities
3
Enrichment and Feed Materials
UF6 is fed into gas centrifuges that separate the lighter U-235 isotope which is typically enriched to up to 5%
4
Fuel Fabrication
The enriched UF6 is converted back to uranium oxide (UO2) and is now called enriched uranium product (EUP). The EUP in powder form is then pressed and sintered into pellets before being put into fuel rods
5
Electricity Generation
The fuel rods are loaded into reactors and used to generate steam. This drives turbines which power electricity generators
6
Reprocessing and Recycling
Recovered uranium from reprocessing can be converted to UF6 and then re-enriched into new fuel
