▶ 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 HD Hyundai is partnering with TerraPower and Hyundai E&C to accelerate its push into the U.S. small modular reactor (SMR) market. 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.

▶ Highest Tier Certified by Leading Global Environmental Safety Science Organization ▶ Custom Recovery Solutions Turn Foundry Sand, Waste Synthetic Resins, Dust, and Cutting Fluids into New Resources ▶ Eco-Lubricants and Recycled Materials Drive Circularity Across Full Product Lifecycle HD Construction Equipment announced on the 12th that its Incheon Campus has received the highest Platinum rating for Zero Waste to Landfill (ZWTL) certification from UL Solutions, a global leader in safety science, for the second consecutive year. ZWTL is an international certification that assesses a facility's ability to manage resources in a circular manner. It verifies waste management practices, including recycling and energy recovery, based on the waste generated at business sites. Facilities are awarded ratings of Platinum (100%), Gold (95–99%), or Silver (90–94%) based on their recycling rates. After achieving a Gold rating for four consecutive years starting in 2021, the HD Construction Equipment Incheon Campus became the first facility in the construction machinery industry to reach a recycling rate of 99.54% last year, earning its first Platinum rating. By maintaining this top-tier status again this year, the plant has demonstrated its ongoing commitment to resource circularity. HD Construction Equipment is dedicated to developing resource recovery methods specifically designed for the unique characteristics of each type of waste. For example, foundry sand, which is used to mold products by pouring molten metal, and process dust are processed separately for recycling into raw materials. Waste synthetic resins and waste wood are shredded to create Solid Refuse Fuel (SRF), while cutting fluids used in metal machining are reused after impurities are removed. To reduce packaging waste from the delivery of raw materials and components, the company has replaced traditional wooden pallets and cardboard boxes with steel pallets and reusable Danpla (plastic) boxes. Additionally, it has implemented a resource circularity system to collect and reuse used packaging materials. HD Construction Equipment is enhancing its resource circularity initiatives beyond just managing waste on the shop floor. The company is now focusing on improving resource sustainability throughout the entire product lifecycle, which includes development, operation, maintenance, and disposal. To reduce the environmental impact at the end-of-life stage of its equipment, HD Construction Equipment has developed biodegradable lubricants that are suitable for hydraulic systems and engines in construction machinery. In addition, the company has developed parts made with 20% to 30% recycled materials and is currently validating their performance for use in both internal and external product components. "Earning the ZWTL Platinum rating for two consecutive years is a testament to the ongoing efforts of our executives and employees to establish a resource circularity framework and minimize waste," stated an official from HD Construction Equipment. "We will continue our resource circularity initiatives throughout all aspects of our operations, from plant management to product usage and disposal."
