French engineers are developing a new type of modular nuclear reactor that will not generate electricity. Called Archeos, its sole purpose is to supply heat to large industrial plants, marking a departure from virtually all other small modular reactor (SMR) concepts.
Most SMR projects worldwide aim to produce power, often in combination with heat. Archeos, however, is a 100 MW thermal unit designed to deliver steam at temperatures between 100 and 200 degrees Celsius. The heat is intended for energy-intensive industries such as chemicals, food processing, paper production, and cement manufacturing, where it could also be used in carbon capture processes.
The reactor is being developed by a joint venture between France’s Alternative Energies and Atomic Energy Commission (CEA) and Nuvia, a subsidiary of the Vinci Construction group. Nuvia employs around 4,100 people and operates in 17 countries, focusing on nuclear energy, defence, nuclear medicine and environmental services. CEA, with 22,600 staff, is a major research body covering low-carbon energy, digital technologies, medical tech, and security.
Industrial heat without fossil fuels
Many factories currently generate process heat by burning coal, gas, or biomass. Switching to nuclear heat would cut carbon emissions and reduce dependence on fossil fuel supply chains. The Archeos design is particularly suited for the cement industry, which needs high-temperature steam to run carbon capture systems and could thus become a net zero emitter.
The timeline is ambitious. The reactor’s final design is expected by the end of this decade, with construction starting in 2032 and commissioning in 2035. French planners hope to have ten Archeos units in operation by 2040, serving industrial hubs across the country.
A new player in the SMR market
Archeos enters a crowded but still emerging global SMR market. Its creators forecast that by 2050, the annual value of the worldwide SMR market could reach between 70 and 120 billion U.S. dollars. Unlike competitors that focus on power generation, Archeos targets a niche: industrial customers who need steady, carbon-free heat and cannot easily electrify their processes.
The project also aligns with France’s strategy to maintain its nuclear expertise while decarbonising heavy industry. If successful, Archeos could become a blueprint for other countries looking to replace coal-fired industrial boilers with nuclear heat, especially in regions with limited grid capacity for additional electricity generation.
