Therefore,
Stellaria finances its innovative nuclear:
The Grenoble start-up Stellaria. Meanwhile, from the atomic energy police station (CEA) and Schneider Electric, announced, on July 17, a fundraising of twenty-three million euros. Therefore, This funding supports the development of a fourth generation nuclear reactor. Consequently, based on a unprecedented double technology: melted and fast neutrons. Nevertheless, An extraordinary project, at the heart of the French strategy for energy reindustrialisation.
A structuring fundraising for Stellaria – Stellaria finances its innovative nuclear
Stellaria has convinced several players to invest in this radically innovative project. Meanwhile, The American Fund at One Ventures. Nevertheless, the European Supernova Invest lead the Tour de Table, joined by historic partners: CEA Investissement, Schneider Electric, Exergon and Technip Energies. Furthermore, To this private support is added a public subsidy of ten million euros. Meanwhile, obtained within the framework of the “innovative reactors” system of the France 2030 plan. Nevertheless,
According to stellaria finances its innovative nuclear the article published in Lyon Capitale on July 24. In addition, 2025, this envelope will allow Stellaria to accelerate its technical and regulatory work, and to double its workforce. “” This fundraising demonstrates the confidence of investors in the technical maturity of our reactor with melted salts … It is a key step towards the sustainable reindustrialisation of our territory “Says Nicolas Breyton. co -founder and managing director of Stellaria.
Stellarium. heart of a technological turn
Stellaria’s ambition: design by 2029 an operational prototype of its reactor called Stellarium, before a placing on the market planned for 2035. This system is based on two rarely combined technological pillars: a liquid fuel (melted salts) and a rapid neutron spectrum. A strategic choice, intended to maximize fission and drastically reduce radioactive waste. In this type of reactor. fast neutrons make it possible to use fuels that are not very valued stellaria finances its innovative nuclear in conventional pressurized water reactors.
Stellarium will thus be able to consume depleted uranium, plutonium from reprocessing, or even thorium. It also targets over -generation: producing as much, or even more fuel than it consumes. The start-up aims at an autonomy of twenty years without recharging, for a sufficient capacity to supply up to 400,000 people. An unprecedented perspective that makes Laurie Ménoud. AT One Ventures, in Lyon Capital: “ Their reactor offers a weak capex and lcoe, passive safety with cooling in 72 hours, flexibility on fuels and a rapid rise in power … Stellaria does not only build a reactor, it builds the future of nuclear energy ».
A response to the nuclear challenges of the future
The model proposed by Stellaria is easier to build. faster to deploy and more flexible to operate. Installed underground, the reactor is equipped with four containment barriers. Its stellaria finances its innovative nuclear passive security device guarantees automatic stopping of the reaction in case of overheating, without human intervention. This level of security, associated with low internal pressure of the reactor, considerably reduces the risks of serious accident. But this technology is still not very proven.
The International Atomic Energy Agency (AIEA) underlines. in remarks reported by Lyon capitalthat « Analyzes of the scenarios of potential accidents specific to RSF are generally little known, and it is necessary to conduct more experiences and trials of demonstration of security ». This is precisely the object of the upcoming work of Stellaria: to demonstrate that the intrinsic safety of the. Stellarium meets the strictest requirements.
