newcleo SA is a nuclear technology company developing advanced modular reactors (AMRs), with a focus on lead‑cooled fast reactor (LFR) designs in the ~200 MWe class. Its approach emphasizes inherent and passive safety features, compact modular construction, and the capability to utilize mixed‑oxide (MOX) fuel derived from recycled materials to support a more circular nuclear fuel cycle and reduce long‑lived waste.
newcleo aims to provide reliable, low‑carbon electricity and high‑grade heat for energy‑intensive industries. Its reactor systems are being designed for integration with downstream processes such as hydrogen and ammonia production, offering firm power and process heat to help decarbonize chemical and related industrial value chains. The company is advancing first‑of‑a‑kind projects with engineering partners, progressing basic design and balance‑of‑plant development ahead of expected investment decisions later in the decade.
