The French company Calogena has signed a letter of intent with the French Atomic Energy and Alternative Energies Commission (CEA) to evaluate the possible installation of its CAL30 small modular reactor at the Cadarache site in Saint-Paul-Lez-Durance, France.
The aim is to analyze the technical feasibility of locating the nuclear module in an already selected area within the CEA facilities, as well as its connection to the center’s heating network.
About the CAL30 SMR
Calogena, a subsidiary of the Gorgé Group, has been developing since 2021 a low-power nuclear boiler designed to decarbonize heat production in cities. Its design, known as CAL30, delivers a thermal power of 30 MW, operates at low pressure and low temperature and is specially optimized for integration into district heating networks.
In addition, its compact size (3,000 m2 of land and less than 1,000 m2 in buildings) and its design based on internationally proven pool reactors allow for simplified installation and minimal logistical maintenance. It only requires refueling every two years, using a single truck.
Cadarache as a platform for energy innovation
CEA’s Cadarache site is one of Europe’s most important hubs for nuclear technologies and low-carbon energy. With more than 2,600 employees, it houses key facilities such as the Jules Horowitz reactor and the WES tokamak, and is part of France’s strategic programs for energy transition.
The possible integration of the CAL30 module into its internal thermal network would make it possible to test a model that could be replicated in other industrial or urban environments. If successful, this project would position France as a benchmark in the use of nuclear energy. nuclear energy for district heating, a growing need in the face of climate urgency.
CAL30 was one of the projects selected by the General Secretariat for Investment (SGPI) under the “Innovative Nuclear Reactors” program in 2023. Calogena is currently advancing in the third phase of the technical evaluation process by the French Nuclear Safety Authority. French Nuclear Safety Authority (ASN) (ASN), which will help refine the regulatory design and prepare for deployment by 2030.
