Stellaria Secures Significant Funding for Advanced Molten Salt Reactor Technology
Paris, France – July 24, 2025 – Stellaria, a pioneering French startup at the forefront of next-generation nuclear energy, today announced the successful closing of a €23 million funding round. This substantial investment underscores the growing confidence in Stellaria’s innovative approach to molten salt nuclear reactor (MSNR) technology and its potential to contribute to a sustainable energy future.
The funding round was led by [Insert Lead Investor Name Here, if available from the PRNewswire article – otherwise omit or generalize], with participation from [Insert Other Investors Here, if available – otherwise omit or generalize]. This capital infusion will be instrumental in accelerating Stellaria’s development and deployment roadmap, focusing on key areas such as advanced design, regulatory engagement, and the construction of their prototype reactor.
Stellaria is developing a molten salt reactor that promises inherent safety features, enhanced fuel efficiency, and a significantly reduced environmental footprint compared to traditional nuclear power plants. Molten salt reactors utilize a liquid fuel, where uranium or thorium is dissolved in a molten fluoride or chloride salt. This design offers several key advantages, including the ability to operate at higher temperatures, leading to greater thermal efficiency and the potential for electricity generation and industrial heat production. Furthermore, MSNRs can operate at atmospheric pressure, eliminating the risk of catastrophic steam explosions, and can be designed to consume existing nuclear waste, offering a promising solution for waste management.
The team at Stellaria, comprised of experienced nuclear engineers, physicists, and entrepreneurs, is committed to advancing this promising technology. Their work aims to address the global demand for clean, reliable, and secure energy sources while mitigating the challenges associated with conventional nuclear power.
“We are thrilled to have secured this significant funding, which will empower us to accelerate the development of our revolutionary molten salt reactor technology,” said [Insert CEO Name Here, if available] , CEO of Stellaria. “This investment is a testament to the hard work of our dedicated team and the immense potential of MSNRs to reshape the energy landscape. We are confident that our approach will contribute to a cleaner and more sustainable energy future for generations to come.”
The successful fundraising round positions Stellaria to make significant strides in bringing their advanced reactor designs closer to commercial viability. The company’s focus on safety, efficiency, and environmental responsibility aligns with the global imperative to decarbonize energy systems and combat climate change. With this strong financial backing, Stellaria is poised to play a vital role in the evolution of nuclear energy and its contribution to a low-carbon world.
