What Framatome does

Framatome is a privately held French nuclear steam supply system (NSSS) designer and manufacturer and a wholly owned subsidiary of Électricité de France (EDF). The company provides integrated solutions across the full nuclear power plant lifecycle — from new build construction through long-term operations, upgrades, and decommissioning — serving commercial nuclear utilities, government defense agencies, and space programs. Its installed base covers approximately 67% of the world's operating nuclear reactors, supported by 70+ sites in more than 20 countries and roughly 22,000 employees.

The company's core technology stack centers on proprietary nuclear fuel designs (HTP, GAIA, FOX, ATrium 11, and TRISO for advanced reactors), safety instrumentation and control systems (including the IEC 61513-certified TXS Compact platform), and the manufacture of nuclear-grade components such as reactor vessels, steam generators, primary circuits, and pressurizers. Recent technical milestones include US NRC approval for high-burnup fuel limits on GAIA and HTP designs, NRC authorization to manufacture assemblies with U-235 enrichment above 5% at the Richland facility, additive manufacturing partnerships for nuclear-grade parts with Perpetual Atomics, and TRISO particle fuel co-development with Standard Nuclear for next-generation reactors.

Framatome operates an enterprise field sales model with multi-year contracts directly to nuclear utilities and government agencies. Revenue is generated across three primary streams: nuclear fuel manufacturing (one-time license-style reload contracts), nuclear equipment and components (project-based sales), and long-term service contracts (recurring subscription revenue covering outage management, maintenance, and Long-Term Operation support). The company generated €5.4 billion in FY2025 revenue, with named customers including EDF (France, 50+ reactors), ČEZ (Czech Republic), Fortum (Finland), Barakah (UAE), CNNC and CGN (China), Hinkley Point C and Sizewell C (UK), and Nuclearelectrica (Romania), as well as defense and space programs including the European Space Agency.
