The Calogena solution
Calogena is a subsidiary of the Gorgé industrial group.
Calogena offers an innovative and promising solution for decarbonising and extending heating networks. Calogena is developing a small modular reactor (SMR), designed specifically for district heating. This project represents a major advancement in the field of heating decarbonisation. The Calogena module, which has a thermal capacity of 30 MW, delivers low-carbon heat to 20,000 homes.
Calogena is supported by France 2030.
A safe, proven and competitive nuclear solution for district heating
Calogena already has its own EPR nuclear fuel, developed in collaboration with Framatome and Orano. Nuclear waste management will be strictly identical to that of existing power reactors. Calogena’s intrinsically safe operation has been built on the physical exclusion of a core meltdown. This principle has already been applied for several decades by research reactors delivering similar power levels to Calogena, installed on the outskirts of cities (Grenoble, Munich, Vienna, etc.).
The Calogena solution delivers competitive heat production at a price that remains stable over time, guaranteeing reliability and sovereignty. Calogena is in the running for the first nuclear call for tenders for district heating in Finland, and several French towns have already expressed an interest in deploying the solution.
Seres Technologies: a key player in the design and development of the Calogena SMR
Drawing on its experience and expertise in the nuclear sector, Seres Technologies is supporting Calogena with the design of its new-generation SMR, and more specifically in the SPD (Summary Preliminary Design), DPD (Detailed Preliminary Design) and industrialisation (manufacturing, operation and maintenance) phases.
For this, Seres Technologies has drawn on its historical expertise in risk management and complex systems engineering.
The Seres Technologies teams are working on the management of the digital mock-up, the design and mechanical preliminary sizing of the components, the thermal and thermodynamic study and the estimation of electricity consumption in the event of autarky (power cuts). Seres Technologies has also made major contributions to the drafting of the DOS (Safety Options Dossier), which required expertise in nuclear safety, operational safety and OHF.
A direct outcome of Gorgé’s entrepreneurial drive, the alliance between these two subsidiaries represents an exceptional synergy of skills.
As a result, Calogena can has a trusted partner that it can rely on, moving forward with peace of mind for development phases and offering a secure, future-proof technological solution.
