France aims to initiate a carbon-free heating era in cities with the 30 MW CAL30 small modular reactor<\/strong> planned for installation at the Cadarache research center.<\/p>\n\n\n\n

French energy technology company Calogena<\/strong> has begun to evaluate the installation of a small modular nuclear reactor (SMR)<\/strong> at the Cadarache research and development center. In this context, the company has signed a letter of intent with the French Alternative Energies and Atomic Energy Commission (CEA)<\/strong>.<\/p>\n\n\n\n

The CAL30<\/strong>, which is planned to be deployed at the selected site, will be a water-cooled SMR with a 30 MW thermal power output<\/strong>. The reactor’s design is optimized to operate at low pressure (6 bar)<\/strong> and low temperature (100 \u00b0C)<\/strong>. Calogena<\/strong> states that the CAL30<\/strong> aims to provide clean energy<\/strong> to urban heating networks and is intended to be commissioned as soon as possible, around 2030<\/strong>.<\/p>\n\n\n\n

Calogena’s reactor<\/strong> uses classical nuclear fuel<\/strong> but in a more compact form. The company emphasizes that the CAL30<\/strong> requires only 3,000 m\u00b2<\/strong> of land and less than 1,000 m\u00b2<\/strong> for buildings. The reactor does not need extensive water or electricity infrastructure, and refueling<\/strong> can be carried out by a truck only once every two years. The design, specifically optimized for urban heating networks<\/strong>, is suitable for providing energy based on demand. The reactor can perform load-following<\/strong> and can be brought online quickly.<\/p>\n\n\n\n

Operating at low pressure and low temperature<\/strong>, the CAL30<\/strong> is much simpler and safer than conventional reactors due to its direct heat utilization<\/strong> and limited auxiliary systems. The reactor’s core volume is less than 1 cubic meter<\/strong>. This allows the system and components to be assembled in a factory environment and then transported to the installation site. Consequently, installation is radically expedited.<\/p>\n\n\n\n

The CAL30<\/strong> is one of four SMR designs<\/strong> being evaluated in France. While the Blue Capsule<\/strong> and Naarea<\/strong> designs are still in the preparatory phase, the CAL30<\/strong> has already advanced to the pre-licensing stage. Furthermore, another SMR design<\/strong> named Jimmy<\/strong> has requested a “decree of authorization for installation” from the ASNR<\/strong> for deployment at a Cristal Union Group<\/strong> facility to provide heat for industrial purposes.<\/p>\n\n\n\n
