- HD Hyundai, TerraPower and Hyundai E&C held first executive-level meeting since signing MOU in May
- Chairman Chung Kisun says partnership will accelerate commercialization of Natrium reactors
- HD Hyundai aims to build capacity to produce 2-3 primary Natrium® components annually, deepening Korea-U.S. cooperation
SEOUL, South Korea, Aug. 14, 2026 /PRNewswire/ — HD Hyundai is partnering with TerraPower and Hyundai E&C to accelerate its push into the U.S. small modular reactor (SMR) market.
On Friday, August 14, HD Hyundai Chairman Chung Kisun met with TerraPower Founder and Chairman Bill Gates to discuss cooperative measures for the commercialization of land-based nuclear reactors.
HD Hyundai said Chairman Chung Kisun, TerraPower Founder and Chairman Bill Gates, TerraPower President and CEO Chris Levesque, and Hyundai Engineering & Construction CEO Lee Han-woo met in Seoul on Aug. 14 to discuss the collaboration.
This was the first meeting among the top executives of the three companies since HD Hyundai, TerraPower and Hyundai E&C signed a trilateral memorandum of understanding in May to cooperate on next-generation sodium reactor projects.
At the meeting, Chairman Chung and the other executives held in-depth discussions on a range of cooperation opportunities to commercialize land-based reactors, building on progress made to date.
“We expect this cooperative framework, which spans technology, manufacturing and EPC, to accelerate the commercialization of next-generation Natrium reactors,” Chairman Chung Kisun said. “We will actively respond to growing demand for SMR-based power generation through our own technology development and collaboration with global companies.”
HD Hyundai has been refining the scope of its supply chain cooperation and plans to accelerate investment in production facilities ahead of commercialization, with the goal of eventually supplying two to three reactor vessels annually.
The U.S. is the world’s largest nuclear power market, with approximately 95 gigawatts (GW) of installed capacity, accounting for about 25% of the global total. As a significant portion of the country’s nuclear power facilities began operations in the 1970s and are aging, demand to replace aging reactors is expected to increase substantially in the years ahead.
In addition, rapidly growing electricity demand driven by the recent expansion of data centers in the U.S. is further increasing demand for nuclear power.
The three companies previously signed an MOU in May to establish a collaboration framework for the commercialization of Natrium, a next-generation SMR based on sodium-cooled fast reactor (SFR) technology. Under the agreement, TerraPower will provide Natrium technology, HD Hyundai will manufacture major equipment, and Hyundai E&C will provide engineering, procurement and construction (EPC) support for selected projects.
HD Hyundai joined TerraPower’s visionary investor base in 2022, followed by an order from TerraPower in December 2024 to manufacture cylindrical reactor vessels for the Natrium reactor.
In March 2025, HD Hyundai signed a strategic agreement with TerraPower to expand the manufacturing supply chain for the commercialization of Natrium reactors and conducted a yearlong study on manufacturing feasibility, price competitiveness and delivery schedules.
Building on these achievements, HD Hyundai was named the preferred bidder in May to manufacture and supply key equipment for TerraPower’s Natrium reactors.
