Nuclear Fuel Supply Chain

URENCO plays a key role in the global nuclear fuel supply chain. Our enrichment services enable customers to produce low carbon electricity through nuclear generation. 


Uranium ore is extracted, purified and milled to become uranium oxide, also known as ‘yellow cake’.


Uranium oxide is chemically converted into uranium hexafluoride (UF6), otherwise known as feed, and transported to one of our enrichment facilities.

Enrichment & feed materials

Our customers’ UF6 arrives at our enrichment facilities. We heat the UF6, turning it into a gas which we feed into our centrifuges. The centrifuges separate the two isotopes contained in uranium, U235 and U238, and enrich the lighter U235 to up to 5%. Our centrifuges also enable us to conserve feed material, which means we can provide EUP and natural uranium in addition to enrichment services

Fuel fabrication

The customers’ enriched uranium is transported to fuel fabricators, where it is converted into pellets before being loaded into fuel rods.

Nuclear power generation

The fuel rods are transported to nuclear power stations, where they power nuclear reactors. Fuel rods are placed into the reactors, generating steam which drives turbines which in turn power generators.

Electricity distribution

Nuclear power plants provide a secure source of low carbon energy, generating electricity for homes, schools, hospitals, offices and industries around the world.
