The signing of the MoU between X-energy, Amazon, KHNP and Doosan Enerbility.
The partnership focuses on the development and cost-effective deployment of X-energy’s Xe-100, a fourth-generation SMR designed to generate 80MW per unit, with a total capacity of 5 gigawatts across 64 units by 2039. The reactors will primarily power Amazon Web Services’ AI data centers. The collaboration includes efforts in reactor engineering, supply chain development, construction planning, investment strategies, and long-term operations, with potential for global AI-nuclear projects.
Amazon Web Services Worldwide Energy head Vibhu Kaushik stated: “By forming this partnership with KHNP and Doosan along with X-energy, we’re continuing to pursue innovative carbon-free solutions and technology to help meet the increasing energy demand, and we’re excited that this will help us enable over five gigawatts of new nuclear energy in the US.”
The agreement aligns with a broader $350 billion trade deal between the United States and South Korea, aiming to secure up to $50 billion in public and private investments to advance nuclear energy. X-energy CEO J. Clay Sell stated: “By combining our expertise, we are ensuring that we are best positioned to accelerate the Xe-100 SMR into the marketplace with the unique knowledge and skills developed throughout the South Korean industrial supply chain.”
Building on existing partnerships, including a collaboration with South Korea’s DL E&C since 2023, X-energy and Amazon are creating an ecosystem to support reactor delivery. Doosan Enerbility will provide manufacturing capabilities for the Xe-100 modules. X-energy is also advancing its initial Xe-100 project at Dow’s UCC Seadrift Operations site in Texas, supported by the U.S. Department of Energy’s Advanced Research Demonstration Program. In May 2025, the project’s four-reactor construction permit application was accepted for an 18-month review by the U.S. Nuclear Regulatory Commission.
Additionally, X-energy is progressing with a second Xe-100 project in Washington state, in collaboration with Amazon and Energy Northwest. This initiative plans to deploy four reactors, with the potential to expand to 12, further supporting clean energy goals.
This partnership strengthens the development of advanced nuclear technology, combining expertise to deliver reliable, sustainable energy for high-demand industries while fostering international cooperation.
