Seaborg Technologies is a Danish nuclear startup developing the Compact Molten Salt Reactor (CMSR) — a compact, factory-built molten salt reactor targeting floating and land-based deployment at approximately $1 billion per unit for a 100 MWe system. Seaborg has signed cooperation agreements with multiple Southeast Asian nations including Indonesia and Vietnam for potential CMSR deployment. The company raised $45 million in 2024 and is designing for factory mass production — targeting dozens of units per year at commercial scale. The CMSR uses boron-10 enriched molten salt as both fuel and coolant. The CMSR is designed for barge deployment, enabling nuclear power for coastal and island communities, with Southeast Asia (particularly Indonesia and the Philippines) as the primary target market, and Seaborg has a partnership with Samsung Heavy Industries on the barge hull design.
