X-energy and Dow Receive Construction Permit Approval for Long Mott Generating Station

X-energy and Dow received construction permit approval for the Long Mott Generating Station, the first advanced nuclear facility approved for a U.S. industrial site under the Department of Energy’s Advanced Reactor Demonstration Program. The approval enables construction-readiness work, including finalizing X-energy’s Xe-100 reactor design, advancing the supply chain for long-lead components, and preparing a Nuclear Regulatory Commission operating-license application. The project will use Xe-100 reactors and TRISO-X fuel to supply carbon-free energy, and Dow expects to consider a preliminary investment decision in 2027.
