We reload energy reserves for centuries. 

We renew 100% of our fuels thanks to our fast neutronic patented technology.

The power produced is 24/7 , safer, and renewable by module of 110MWe 

"We revisit molten salt proven technology, transforming previous R & D concepts to an easy-to-industrialize & easy-to-maintain solution. In just 4 M3, the energy storage offered is equal to millions of tons of coal, and its density is around 70 million times higher than any Li-Ion equivalent.

We pave the road towards CO2-free electrification, making fast-neutron technology affordable, thanks to a simplified passive design. 

But this is not all...

We found ways to design a very simple, robust and polyvalent pile that can adapt to any kind of country needs

We multirecycle  exMOX and UOX for Water Pressurized Reactors

We burn most of long life minor actinides nuclear waste.

We provide abundant heat and power that is essential for social peace, sovereignty and prosperity



Our partners are very important to us. We team up with the best experts in their domain to build the next generation of SMR's 

Ultra fast dispachable
We can produce the last dispatchable KWh

The dilation of molten salts can stabilize the power at any level, from 0 to 110 MWe, in less than 20 seconds, ideal to follow renewables or fast changing loads of industrial facilities. 

This is unique in the nuclear technologies. No more need for gas power plants to balance the grids. 

Safe by design 
Not by additional safety systems...

Atmospheric pressure, high temperature melted core, and very fast counter reactions allow nautral safety by design, not by procedure. We do not use water at 155 bars, but stable chloride salts (NaCl). 

Thanks to its compact size, its patented design allows passive heat evacuation in case of power shut down.

Renewable refueling
We are also our own mine

The patented design allows the use of multiple fuels, burning either Low Enriched Uranium (LEU), Natural Uranium with plutonium (U/Pu) from existing reactors, or, in the future, Thorium (Th/U). This provides a strong diversification of fuel supply, perfect to reach energy sovereignty.

Moreover, the fuels are renewed in the reactor thanks to the fast-neutrons technology. It renews as much fuel as it consumes. by transforming fertile atoms into fissile atoms little by little throughout the operating time.

Fast neutron technology also enables the transmutation of existing waste, including minor actinides like curium and americium that are coming from current reactors, reducing the decay time from 300 000 years to only 300 years.

All in all, The STELLARIUM's are net-negative in waste : they produce much less long life waste than they burn.


The most compact solution on the market, providing non stop power for 10 years for 150 000 inhabitants in just 10 M3


Patented natural circulation in core that avoid difficult mainteance during operations


An industiral Alliance is under construction to build modules with the best industrial players, who will help us install STELLARIA where they are already settled, starting by Europe. STELLARIA modules will be installed in large industrial facilities in less than 36 months
