The future of fourth-generation nuclear power also speaks Italian and is taking place in Trieste. Among the companies driving technological advancement sponsored by Newcleo, an Italian-French venture focused on improved reactors, Trieste-based Orion Valves stands out. The company manufactures crucial components for the energy sector, with a special emphasis on valves for the Precursor's lead cooling system, which serves as a key technological demonstrator before the final reactor is constructed. The prototype is now under development at the ENEA Brasimone Research Center in the Tuscan-Emilian Apennines. The Precursor, designed as a power plant with around 10 thermal megawatts, does not use fission: the heat required to replicate working conditions is provided by electric heaters, with the goal of investigating the behavior of a lead-cooled system. This offers a significant engineering challenge for Orion Valves, as the components must endure molten lead while adhering to high material and reliability criteria. Founded in 2021 and directed by physicist Stefano Buono, Newcleo has invested €61 million in the Brasimone project over the last four years, with another €40 million anticipated for the next two years. The company intends to create innovative modular reactors using lead as a coolant, with a focus on international markets ranging from Europe to the United States. It plans to build the first 200-megawatt reactor in 2032 and other projects in Slovakia by 2034. As the Italian government strives to renew the debate and national nuclear supply chain, the involvement of enterprises such as Orion illustrates the value of local industry competence in the sophisticated European supply chain.
