What CORE POWER (UK) Ltd does
CORE POWER (UK) Ltd is a London-headquartered (with wholly-owned subsidiaries in Washington D.C. and Tokyo) deep-technology company founded in 2018 that designs, integrates, and deploys ship-based nuclear energy systems — both Floating Nuclear Power Plants (approximately 300 MWe, Gen III+ reactor) and nuclear propulsion systems (Gen IV molten salt reactor) — for maritime decarbonization and industrial energy supply. The company's underlying technology is a molten salt reactor (MSR) architecture adapted for maritime deployment, currently undergoing Integrated Effects Testing at Idaho National Laboratory as part of the Molten Chloride Reactor Experiment (MCRE), the world's first test of a molten chloride salt fast reactor, conducted in collaboration with the U.S. Department of Energy, Southern Company, and TerraPower. CORE POWER is also evaluating BWXT's mPower SMR (195 MWe / 575 MWth) for integration into shipyard-built Floating Nuclear Power Plants, announced on June 17, 2026.
CORE POWER is pre-revenue and sells no commercial product today; first commercial deliveries are targeted between 2030 and 2035, with reactor unit costs targeted at $120-150 million and individual nuclear-powered vessels estimated at approximately $700 million (compared with $150-200 million for conventional diesel ships). The intended revenue model is multi-layered: hardware sales of floating nuclear power plants and nuclear propulsion systems to shipowners, utilities, ports, and energy-intensive industrial facilities; managed power generation services; technology licensing to shipbuilders (including HD Korea Shipbuilding and TerraPower) and energy companies; plus professional-services revenue from the Convoy corporate executive program (120-person cohort, May-November 2026) and an Academic Program. Pricing is not publicly disclosed; sales cycles are multi-year enterprise deals involving IMO, IAEA, NRC, and classification society approvals. Customer concentration today is effectively zero paying customers, but a strategic-partner ecosystem of more than fifteen counterparties (Maersk, Lloyd's Register, ABS, Port of Rotterdam, Baker Hughes, Glosten, BWXT, TerraPower, Southern Company, HD Korea Shipbuilding, Hyundai Heavy Industries, Wan Hai, Express Container Lines, Deon Policy Institute, Athlos Energy) is being assembled to de-risk the regulatory and commercial pathway.
