Calogena secures €48 million France 2030 grant for reactor design
Phase-two support will fund basic design of its district-heating nuclear reactor.
Calogena has been awarded a €48 million subsidy under the second phase of France 2030’s Innovative Small Nuclear Reactors programme. Announced on March 10, 2026, the grant will fund the basic design of its nuclear heat reactor.
The Groupe Gorgé subsidiary is developing a compact reactor for district-heating networks. The award follows completion of its preliminary design and the start of safety reviews in France and Finland.
Calogena also signed a term sheet for a separate capital increase involving Groupe Gorgé, SNEF and Banque des Territoires. That transaction remained subject to conditions at the announcement date. The grant will support engineering work as the company prepares for eventual commercial deployment.
