Calogena has been awarded EUR 40 million by the European Commission’s Innovation Fund toward the potential construction of its first commercial reactor, for the French town of Pierrelatte. The French developer announced the grant on 5 November 2026. It says this is the first time European funding for a small modular reactor has covered the construction of a commercial installation directly, a claim the Commission has not confirmed in the material reviewed.
What Calogena is building
Calogena is a subsidiary of the industrial group Gorgé. It is developing a small water-cooled reactor built for district heating, not electricity. The company describes a low-pressure, low-temperature design that uses the heat directly and needs few auxiliary systems, which it says makes the concept simpler and safer than any reactor now operating or planned. That safety comparison is the company’s claim.
One module has 30 MW of thermal power and supplies about 20,000 households. That is 1.5 kW of heat per household (ENB calculation, 30 MW divided by 20,000). Calogena says it can deploy from 2030.
Why heat, and why Pierrelatte
The company’s case rests on district heating. It states that about 70% of heating and hot water is produced with fossil energy, that more than 70 million Europeans are connected to district heating networks, and that these networks are fuelled by combustion 95% of the time. These are Calogena’s figures and are not independently checked here. A reactor that sells heat to a municipal network has a customer base that does not depend on the wholesale electricity price, which is why developers of heating reactors target towns instead of grids.
| Item | Figure | Status |
|---|---|---|
| Innovation Fund grant | EUR 40 million | Announced 5 November 2026 |
| Reactor module | 30 MW thermal, about 20,000 households | Company design figures |
| First commercial site | Pierrelatte, southern France | Potential construction |
| Deployment target | From 2030 | Company estimate |
Funding and the state of the project
The grant adds to earlier public support. Calogena is a laureate of the French government’s France 2030 programme for innovative nuclear reactors. Through its CityHeat project it is also supported by the European Commission within the European SMR Industrial Alliance. The related Steady Energy project, which is also aimed at district heating, received loan financing that ENB covered in the EIB convertible loan story.
The wording of the announcement matters. The grant will contribute to the potential construction of the reactor. It is not a construction decision. The announcement gives no total project cost, no grant conditions, no licensing timetable for Pierrelatte and no heat customer contract. Those four items decide whether 2030 is realistic.
Calogena is also running a separate project, a nuclear heating plant at the CEA Cadarache site in the Bouches-du-Rhone. A voluntary public consultation on it began on 28 September 2026 and runs to 28 November 2026, with two guarantors appointed by the national commission for public debate.
Dated checks: the Cadarache consultation closes on 28 November 2026. The next signal for Pierrelatte is any licensing filing or heat supply agreement with the town.
