X-energy (Nasdaq: XE) has been named a founding member of Project Prometheus, a research partnership with Idaho National Laboratory, NVIDIA and Amazon Web Services aimed at using artificial intelligence to accelerate advanced nuclear reactor deployment.
Inside the Prometheus Partnership
Prometheus is a three-year initiative that has received $60 million under the U.S. Department of Energy's Genesis Mission program. It brings together 32 national laboratories, universities and private technology developers with the goal of shortening development schedules and lowering operating costs for advanced reactors.
X-energy is joining as a Tier 1 partner, which includes a seat on the project's board of directors, $10 million in private capital, and the use of its proprietary high-temperature gas-cooled reactor design and fuel fabrication data. The company's Xe-100 small modular reactor and TRISO-X fuel will act as a technical platform for the three-year research effort, which will draw on Department of Energy test reactors and supercomputing resources to bring AI into reactor design, licensing, manufacturing, construction and semi-autonomous operation.
X-energy's Nuclear Pipeline
X-energy said it expects to apply advances from the initiative across its commercial project pipeline, which spans more than 11 gigawatts of planned nuclear capacity in the United States and United Kingdom. The company has active Xe-100 projects underway with Dow, Amazon and Centrica, and holds an option with Amazon to deploy over 5 gigawatts of new nuclear capacity by 2039 to support grid reliability and data center demand.
The company's participation builds on its internal use of APEX, a multi-agentic AI platform already deployed across its engineering, licensing and operations teams.
J. Clay Sell, Chief Executive Officer of X-energy, framed the partnership as part of a larger industry shift.
“We stand at the edge of one of humanity's great technical evolutions, and its infrastructure build-out has already begun. We are proud to be part of the coalition driving it forward,” said J. Clay Sell, the CEO of X-energy. “The future belongs to those willing to solve for what's next, and that is exactly what we do at X-energy.”
X-energy describes its reactor and fuel technology as designed to lower costs and shorten construction timelines compared with other small modular reactors and conventional nuclear plants.
