Did you know?
Zirconium is a key material in the production of nuclear fuel. This metal is particularly resistant to corrosion by water and seawater. Combined with ideal nuclear characteristics (transparency to neutrons), its use is widespread for cladding fuels used in all types of light water reactors

Cutting-edge technologies used at every stage in the process

Fuel design & engineering services

Our engineering teams design safe, reliable and performant fuel & rod cluster control assemblies, developing and maintaining cutting edge codes and methods to conceive and license core and fuel assembly designs. With over 100 certified experts, we provide high-level engineering services, covering core management, safety analysis, and research on advanced fuels and reactors. Located at four sites in France, Germany, and the United States, we serve one-third of the reactors in operation worldwide and collaborate with all major safety authorities to ensure the quality and performance of our solutions.

Manufacturing of zirconium components

We control the entire zirconium manufacturing chain, from sponge production to the transformation of alloys into finished products such as tubes, bars, and flat products. We use efficient processes, supported by our Research Center in Ugine. As a world leader in nuclear-grade zirconium, we hold a 30% market share for fuel cladding and Zr sponge, while also developing special alloys for medical prostheses under the Framatome Healthcare brand. With several sites in France, a joint venture in China, and international teams, we combine innovation and excellence.

Manufacturing of fuel assemblies

The manufacturing of fuel assemblies covers the entire process, from uranium conversion chemistry to the assembly of complex technical components. We produce assemblies for all types of light water reactors (PWR, BWR) as well as uranium dioxide (UO₂) powders and gadolinium rods. Our innovations include advanced accident-tolerant fuels (PROtect E-ATF), higher uranium enrichment, and high burn-up rates.

Framatome’s PROtect Enhanced Accident Tolerant Fuel Program
Taking nuclear fuel to the next level

Our experts, with contributions and support from agencies across the globe, have made Framatome’s PROtect program the industry leader in accident tolerant fuel.

As a response to the 2011 Fukushima accident, Framatome initiated the enhanced accident tolerant fuel (E-ATF) program to improve safety for nuclear plant operators.

For the past decade, we have aggressively pursued technologies and solutions for the industry and our customers. Our near- and long-term solutions and implementations are unmatched in the industry.

Our solutions have been implemented in reactors around the world.

  • 6 implementations worldwide
  • 6 different reactor types
  • 2 in Europe
  • 4 in the U.S.
  • more than 120 million chromia-enhanced pellets manufactured
  • 400+ chromium-coated full-length rods in operation
