Radiant Nuclear, a developer of portable, mass-produced nuclear microreactors designed to provide always-on power for defence, disaster response, remote industry and critical infrastructure, has raised more than $300 million in a new funding round to accelerate commercialisation and build its first full-scale factory in Oak Ridge, Tennessee. The capital comes just six months after the company’s previous $165 million Series C and will support scaling operations as Radiant prepares to break ground on its new R-50 factory next year and advance testing of its Kaleidos microreactor at the Idaho National Laboratory’s DOME facility. The latest round was led by Draper Associates and Boost VC, reflecting strong confidence in Radiant’s team and long-term vision for modular nuclear energy. Existing investors also joined the financing, including Founders Fund, ARK Venture Fund and Chevron Technology Ventures, alongside other backers for the company’s continued growth trajectory. Radiant’s founder and CEO, Doug Bernauer, said the funding enables the company to maintain its development milestones and build out production infrastructure capable of delivering factory-built microreactors to customers by 2028. #nuclear #funding #venturecapital #cleanenergy #RadiantNuclear #DraperAssociates #BoostVC #FoundersFund #ARKVentureFund #ChevronTechnologyVentures
