Energy
for centuries

Stellaria reinvents sustainable, fast breeding nuclear power. Discover the Stellarium, the world's first liquid-core reactor capable of renewing 100% of its fuel during operation, incinerating long-lived high-level waste and achieving revolutionary levels of intrinsic safety.

Decarbonize the industry

To meet this challenge, we need a breakthrough technology in the world of dispatchable energy that can compete with gas and coal-fired power stations. The good news is that a Stellaria reactor is 99% CO2 less per MWh.

Our Advanced Molten Salt Reactor (AMR-MSR) can deliver powerful, compact, low-cost energy to the industry. Deep, permanent and competitive decarbonisation is finally possible. 

We are bringing a new, sustainable image to the industry, one that is environmentally integrated into the landscape and respects each country's and people's traditions.

An environmental commitment

The Stellarium is designed to use up all of its fuel during operation and incinerates some of the high-level waste.

Electricity, e-fuels, and high-temperature steam

Petrochemical plants, mines or data centers: the Stellarium reactor brings autonomy, robustness, safety and durability to all industrial sites that have no complete, competitive solution for electrifying their industrial processes. This reactor is the ideal tool to support reindustrialization.
