Seaborg Technologies is a Danish nuclear startup developing the Compact Molten Salt Reactor (CMSR) — a factory-built molten salt reactor targeting 100 MWe units at approximately $1 billion per unit. The company raised $45 million in 2024 and is designing for mass production. Seaborg uses boron-10 enriched molten salt as both fuel and coolant. The company has signed cooperation agreements with Southeast Asian nations including Indonesia and Vietnam. Its compact, floating-capable design is suited to island nations and coastal industrial sites.
