Also known as Otrera New Energy
Otrera (Otrera New Energy) is a French company founded in 2024 in Aix-en-Provence; the business register gives the creation date as 22 March 2024. It develops a modular sodium-cooled fast reactor, in which liquid sodium cools a core of unmoderated fast neutrons, to produce both electricity and heat. Its site describes an architecture of six 50 MW-thermal modules with a reactor vessel of less than 3 metres, and the IAEA's 2024 catalogue lists the Otrera 300 at 300 MW of heat and 110 MWe. The company says it has more than 30 staff and is a winner of the France 2030 programme.

Terms
- Sodium fast reactor
- Liquid sodium coolant with a fast, unmoderated neutron spectrum. Sodium carries heat superbly at atmospheric pressure, but burns in air and reacts violently with water. Large sodium-cooled cores can have a positive sodium void effect that the core design must offset. Fuel is typically metal alloy or mixed-oxide.
