Doosan Enerbility Wins Order for Key SMR Equipment from US TerraPower

Manufacturing of Reactor Guard Vessel and Other Core Components
Supplying Equipment for the First Kemmerer Unit in the U.S.
Expanding Global SMR Equipment Market Reach

Doosan Enerbility has won a contract to manufacture key equipment for small modular reactors (SMRs) with TerraPower, a U.S.-based company. By supplying essential reactor components to TerraPower’s first next-generation nuclear power project in Wyoming, Doosan Enerbility is expanding its efforts to capture a larger share of the global SMR market.

On the 14th, Doosan Enerbility announced that it had signed a contract to produce the reactor guard vessel, reactor support structure, and internal structures for TerraPower’s sodium-cooled reactor.

Following a manufacturing feasibility review agreement for key components of the initial TerraPower unit in December 2024, Doosan Enerbility has been improving the design. The company stated that its enhancements brought the design to a level suitable for actual production orders.

The equipment supplied under this contract will be delivered to the first reactor currently under construction by TerraPower in Kemmerer, Wyoming. The Kemmerer project will feature a next-generation reactor with a capacity of 345 MW. By combining it with a molten salt energy storage system, the power output can be increased to a maximum of 500 MW.

The Kemmerer project is among the first next-generation nuclear power initiatives in the United States to reach commercial-scale construction. Supported by the U.S. government’s advanced nuclear energy expansion policy and having obtained construction approval from the U.S. Nuclear Regulatory Commission (NRC), TerraPower began building the reactor this spring.

TerraPower, a U.S. nuclear technology company founded by Bill Gates, possesses sodium-cooled fast reactor (SFR) technology, a fourth-generation reactor cooled by liquid sodium. Instead of water, the reactor uses liquid sodium as a coolant and induces fission via fast neutrons.

Doosan Enerbility plans to use this contract as a stepping stone to deepen cooperation with TerraPower and solidify its position as a global SMR equipment supplier. Following the initial Kemmerer unit, TerraPower is also pursuing additional projects in the United States and global markets.

Kim Jongdoo, Head of the Nuclear BG at Doosan Enerbility, stated, “This manufacturing contract is based on many years of close cooperation and trust with TerraPower. We will work to successfully execute this project, continuously strengthen our SMR manufacturing capabilities, and broaden our role as a global supplier.”
