Long Mott Generating Station
Dow and X-energy are working to deploy four Xe-100 reactors at Dow’s Seadrift Operations on the Texas Gulf Coast. Supported by the U.S. Department of Energy’s Advanced Reactor Demonstration Program, this first-of-a-kind Xe-100 plant is designed to deliver both electricity and high-temperature steam to power one of Dow’s largest manufacturing sites in Texas.

About the Project
American Technology for American Industrial Leadership
A New Era for Texas Industry
The products used every day in homes, schools, and hospitals start as materials made on the Texas Gulf Coast. Dow and X-energy are working to deploy four Xe-100 reactors at Dow’s Seadrift Operations, supported by the U.S. Department of Energy’s Advanced Reactor Demonstration Program. Once complete, Long Mott Generating Station is expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.
Intrinsic Safety Case
The Xe-100’s safety case starts with its fuel. Each TRISO particle is its own containment, designed to retain fission products at temperatures well beyond any credible scenario, enabling the reactor to shut down automatically, if needed, without operator action or outside power. That fuel will be made in America at TRISO-X’s fuel fabrication facility in Oak Ridge, Tennessee, also supported by the Advanced Reactor Demonstration Program, expanding American energy leadership while ensuring a stable, domestic supply of high-quality fuel.
Power and Steam from One Plant
Industrial facilities need high-quality, high-temperature heat and steam, and an energy solution that delivers it safely and reliably directly at the point of need. The Xe-100’s innovative design enables it to do both within a compact plant footprint, delivering both electricity and high-temperature industrial steam from one energy solution.
New Pathways for Nuclear Licensing
An intrinsically safer design makes for a clearer safety case, and a clearer safety case enables more efficient licensing. Citing the completeness and quality of the application, the NRC set an 18-month review timeline for Long Mott’s construction permit. It then completed the environmental review ahead of schedule, in under one year, making Long Mott the first commercial nuclear reactor in U.S. history to qualify for an Environmental Assessment instead of a multi-year Environmental Impact Statement.
