Otrera, a spin-off of the French Alternative Energies and Atomic Energy Commission (CEA) and a laureate of the France 2030 program, has successfully closed its first funding round, raising €2.5 million. This funding round brought together a distinguished consortium of industrial and financial investors, including Exergon (Audacia's decarbonization fund), Invest For The Future (IFTF), CEA Investissement, RÉEL International, Groupe ADF, EKIUM-Groupe SNEF, AXE CAPITOLE, and FORTIL. These partners bring unparalleled expertise and strategic alignment to the energy transition and nuclear innovation.
This consortium of investors, with strong roots in the energy and industrial sectors, is strategically positioned to address the demands of the energy transition and drive the development of next-generation nuclear technologies, ensuring rapid availability and broad accessibility.
This funding marks a critical step in the accelerated development of Otrera’s Sodium Fast Reactor (SFR), a revolutionary modular nuclear technology designed to address the dual challenges of energy sovereignty and industrial decarbonization. Built on five decades of French research and innovation, further enriched by the advancements of the Astrid project, the SFR stands as a testament to Otrera’s commitment to sustainability and technological excellence.
