Dow, X-energy Proposed SMR Project Receives Historic Construction Permit for Nuclear-Powered Industrial Site

XEDOW
  • The U.S. Nuclear Regulatory Commission approved the Construction Permit Application for four Xe-100 advanced small modular reactors at Dow's Seadrift Operations site in Texas.
  • The Long Mott Generating Station project becomes the first advanced nuclear facility approved for an industrial site in the United States under the Department of Energy's Advanced Reactor Demonstration Program.
  • This approval marks the first NRC Construction Permit for a high-temperature gas-cooled reactor in nearly 60 years, the first-ever pebble-bed HTGR approval, and the first nuclear industrial deployment.
  • The NRC review confirmed the Xe-100 design can be safely sited within an operating industrial site, citing intrinsic safety characteristics & extensive pre-application engagement.
  • The proposed plant will provide electricity & high-temperature steam to Dow's site, replacing existing assets expected to reach end-of-life, with a planned 60-year operating life.
  • X-energy & Dow will finalize the Xe-100 design, mature the supply chain for long-lead components, & develop an Operating License application to submit to the NRC.
  • The Xe-100 reactor is an 80 MWe/200 MWt high-temperature gas-cooled reactor utilizing TRISO-X coated particle fuel, enabling a 400-meter emergency planning zone compared to 10 miles for conventional reactors.
  • Dow expects to make a preliminary investment decision in 2027, with full-scale construction to begin following a final investment decision.
  • The project aims for first delivery in the early 2030s, reducing schedule & cost risks for this first-of-a-kind deployment.
