MSR — Molten Salt Reactor

About

Copenhagen Atomics is a Danish nuclear technology company developing compact, factory-built thorium-based molten salt reactors targeting sub-$1 billion capital cost — enabling mass production of small nuclear plants at scale. In September 2025 the company signed an MOU with Norwegian developer Ocean-Power to jointly study MSR deployment in Norway and Denmark. Copenhagen Atomics represents the growing Nordic nuclear startup ecosystem driven by energy security concerns from the Iran conflict's LNG supply disruption.
