Developed by STELLARIA, a start-up spin-off from the Commissariat à l’Energie Atomique (CEA, French Nuclear State Agency) and SCHNEIDER ELECTRIC, the STELLARIUM project aims to study, develop and manufacture molten-salt fast neutron nuclear reactors to decarbonise industry. The reactor concept provides 250 MW of thermal power (heat at 600°C) or 110 MW of electrical power (electrical efficiency of 45%) during 20 years without. This is achieved using fast neutrons to fission and fertilise the fuel inside the reactor vessel. The reactor operates by natural convection in normal operation, which simplifies the design and increases the level of nuclear safety. This type of reactor is highly dispatchable, making it compatible with a wide range of industrial applications. All of the reactor's components are designed to be exchangeable, which facilitates maintenance and repair operations.
