Italian startup secures parts to build tiny nuclear reactors by 2028

Terra Innovatum Global N.V., an Italian startup specializing in micro-modular nuclear reactors, has achieved a significant milestone by securing its supply chain for both critical and non-critical components needed to build its SOLO reactor. The SOLO reactor, conceptualized in 2018, is designed as a tiny nuclear fission unit with a maximum capacity of 1 MWe, scalable up to 1 GW through modular deployment. Its unique features include the use of off-the-shelf components for cost-effectiveness and rapid deployment, as well as fuel flexibility supporting both LEU+ and HALEU fuels. These reactors are intended to replace fossil-fuel-powered thermal plants and can provide electricity and heat for industrial processes, especially in off-grid or mini-grid settings. The secured supply chain covers nuclear-grade critical components such as the pressure vessel, cooling tubes, control mechanisms, instrumentation, and reactor fuel, which represent the highest barriers to nuclear reactor construction. Additionally, non-nuclear grade yet mission-critical components like helium circul
