Doosan Enerbility said on the 14th that it had won a contract to produce key equipment for TerraPower’s sodium-cooled reactor.

Under the deal, Doosan Enerbility will manufacture the reactor vessel, reactor support structure, and internal structures for TerraPower’s sodium-cooled reactor. The equipment will be supplied for the first 345MW project under construction in Kemmerer, Wyoming.

Earlier, in December 2024, Doosan Enerbility signed a fabrication review contract for the key equipment of TerraPower’s first unit. Since then, it has developed and applied design improvements to support successful manufacturing, raising the design maturity to a level ready for ordering. Through this process, the two companies strengthened their partnership by combining TerraPower’s reactor technology and safety with Doosan Enerbility’s advanced manufacturing capabilities.

TerraPower’s first nuclear power plant project is one of the first next-generation reactor projects in the United States to enter commercial-scale construction. Backed by U.S. policy support for the expansion of advanced nuclear power, the project obtained a construction permit from the United States Nuclear Regulatory Commission (NRC) and began construction in the spring of 2026. The equipment supplied by Doosan Enerbility is expected to play a key role in the timely construction and commercial operation of the first unit.

TerraPower has design technology for the Sodium-Cooled Fast Reactor (SFR), a fourth-generation reactor that uses liquid sodium instead of water as a coolant, and can raise power output to as much as 500MW when combined with a molten salt energy storage system. The company is pursuing additional contracts to expand SMR deployment and enter global markets.

Kim Jong-du, head of Doosan Enerbility’s Nuclear Business Group, said, “This contract was signed on the basis of the long-standing cooperation and trust we have built with TerraPower.” He added, “We will carry out the project without disruption and continue strengthening our SMR manufacturing capabilities to expand our role as a global supplier.”
