• X-energy has joined the Prometheus project as a Tier 1 founding partner, committing $10 million in private capital and reactor data.
• The three-year initiative received $60 million under the U.S. Department of Energy’s Genesis Mission to apply AI across advanced nuclear development.
• Research will support X-energy’s 11 GW commercial pipeline, including projects with Amazon, Dow and Centrica.

X-energy has joined a new U.S. research initiative designed to accelerate advanced nuclear deployment through artificial intelligence.

The company will participate as a founding Tier 1 partner in the Prometheus project. Idaho National Laboratory, NVIDIA and Amazon Web Services are leading the initiative.

The three-year project has secured $60 million through the U.S. Department of Energy’s Genesis Mission. It will focus on reducing development timelines and operational costs across advanced nuclear technologies.

X-energy will contribute $10 million in private capital. It will also provide access to technical data from its Xe-100 small modular reactor and TRISO-X fuel technologies.

AI moves into nuclear development

Prometheus brings together 32 U.S. laboratories, universities and private technology developers.

The coalition plans to use advanced AI models to support scientific discovery and improve nuclear deployment workflows. Research will cover reactor design, licensing, manufacturing, construction and operations.

X-energy’s Xe-100 reactor and TRISO-X fuel will serve as technical platforms during the research campaign.

The work will combine Department of Energy test reactors and supercomputing infrastructure with AI models capable of supporting complex engineering processes.

X-energy said the technology could eventually assist semi-autonomous operations and fuel manufacturing. It could also reduce routine workloads associated with regulatory and engineering analysis.

The company expects to apply successful developments across its commercial portfolio.

“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, 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.”

Focus turns to licensing and construction

Advanced nuclear developers continue to face long development schedules, regulatory complexity and high construction costs.

Prometheus will test whether AI can shorten those processes without reducing safety or oversight requirements.

Licensing remains one of the most important areas for commercial deployment. Reactor developers must manage large volumes of engineering data and regulatory documentation before projects can move into construction.

X-energy has already been developing its own AI capabilities through APEX, a proprietary multi-agent platform.

The company currently uses APEX across engineering, licensing and operations teams. Its internal AI workflows support technical analysis and routine decision-making.

Participation in Prometheus could allow X-energy to integrate research from national laboratories and technology partners into that existing platform.

The company said this could improve its ability to deploy new tools quickly across projects.

11 GW pipeline raises commercial stakes

X-energy is advancing more than 11 GW of planned nuclear capacity across the United States and United Kingdom.

Its commercial Xe-100 projects include partnerships with Dow, Amazon and Centrica.

X-energy and Amazon also hold an option to deploy more than 5 GW of new nuclear capacity by 2039. The planned capacity would support electricity demand from AWS data centers while strengthening grid reliability.

That connection between nuclear power and digital infrastructure is becoming increasingly important.

AI expansion is driving expectations for substantial growth in electricity demand from data centers. Technology companies are therefore looking for generation sources that can provide low-carbon power around the clock.

Advanced nuclear developers see that demand as a potential route to larger project pipelines and stronger long-term power contracts.

For X-energy, Prometheus could help address one of the sector’s central commercial challenges: moving reactors from design and licensing into repeatable deployment.

Investors watch execution risk

The initiative also has implications for infrastructure investors and corporate energy buyers.

AI may reduce some development costs and improve project efficiency. However, reactor economics will still depend on regulatory approvals, supply chains, manufacturing capacity and construction performance.

Government support remains central. The Department of Energy’s $60 million award places Prometheus within a broader U.S. effort to combine public research infrastructure with private capital and technology.

For energy executives, the project offers another test of whether digital tools can materially shorten nuclear development schedules.

If successful, the research could help advanced reactors compete more effectively for rising power demand from data centers, industrial facilities and increasingly constrained electricity grids.

The wider significance will depend on whether those efficiency gains translate into licensed, financed and operating reactors at commercial scale.
