Blue Capsule Technology is a French nuclear energy company founded in 2022 that is developing a high-temperature reactor (HTR) intended primarily for industrial heat applications.[1]
The company originated within the ecosystem of the French Alternative Energies and Atomic Energy Commission (CEA) and is supported by the French government’s France 2030 innovation programme.[2]
Technology
Blue Capsule is developing a sodium-cooled, high-temperature reactor with a reported thermal capacity of approximately 150 MWth. The reactor is designed to supply industrial process heat at temperatures of up to 700°C, steam up to 650°C, and up to 50 MWe of electricity when required.[3]
The design combines high-temperature reactor (HTR) technology with liquid sodium cooling. [4]. Sodium cooling allows operation at atmospheric pressure and reduces reliance on water-based cooling systems.
The reactor is intended to operate for approximately 60 years, according to company statements.[4]
Fuel
The reactor is designed to use low-enriched uranium (LEU) below 5% enrichment.[5]
The design incorporates TRISO (tristructural-isotropic) fuel particles. In 2025, Blue Capsule announced cooperation with Framatome regarding TRISO fuel qualification and fabrication.[6]
Industrial focus
Blue Capsule focuses on high-temperature industrial heat applications, including cement production, metal refining (e.g. alumina), chemical production, steelmaking, hydrogen production via high-temperature electrolysis, and synthetic fuel production.[1]
External reporting has described the project as targeting the replacement of fossil-fuel-based industrial heat in energy-intensive sectors.[3]
Development and funding
In November 2023, Blue Capsule received funding under the France 2030 programme through the public investment bank Bpifrance, alongside private investment.[1]
Private investors reported in industry coverage include Audacia, Exergon, EREN Groupe, and CEA Investissement.[3]
In May 2025, the project advanced to Phase 2 ("Preparatory Review") in discussions with France’s nuclear safety authority.
In February 2026, the company announced the start of construction of ELISE, a full-scale, high-temperature sodium test loop, at Peyrolles-en-Provence, in collaboration with CSTI Groupe.[7]
The company has outlined a roadmap targeting the start of construction of a first-of-a-kind reactor in 2029-2030, with commercial deployment planned in the mid-2030s.[4]
