newcleo, founded in 2021 and headquartered in France, is rapidly emerging as a leader in the nuclear energy sector. Their slogan, "Developing Lead Fast SMRs to provide the world with a safe, stable power source and reduce volumes of radioactive waste," encapsulates their innovative approach. The company focuses on building Gen-IV Advanced Modular Reactors (AMRs) which utilize liquid lead cooling and reprocessed nuclear waste fuel.
By integrating existing technologies with a revitalized nuclear model, newcleo aims to achieve a closed nuclear fuel cycle, effectively producing sustainable energy for low-carbon economies. Their strategy is backed by substantial private funding of over EUR 537 million, generating a projected group turnover of EUR 50 million by 2024. The company's expansive growth includes strategic acquisitions, bolstering capabilities in nuclear engineering and waste management.
Notably, newcleo secured a EUR 75 million early VC investment in February 2026 from prominent investors such as Indaco Venture Partners, Pension Partners, and Kairos, among others. With a workforce surpassing 950 across France, the UK, Italy, Switzerland, and Slovakia, they are not only achieving their ambitious timelines but also setting the stage for enhancing the Small Modular Reactor supply chain in Europe.
