Calogena develops compact nuclear heat modules for district-heating networks.
Product
Calogena develops small modular nuclear reactors that supply heat directly to urban heating networks. Its 30 MW thermal module uses water-based reactor technology at low temperature and pressure, avoiding the need to generate electricity before delivering heat.
A subsidiary of Groupe Gorgé, the company combines the industrial group’s resources with a team experienced in nuclear engineering. It is working toward an initial commercial installation in Pierrelatte and deployment across European heating markets.
