NRC permits construction of four Xe-100 reactors at Dow's Seadrift site
The NRC issued a construction permit on Nov. 9, 2026 for the Long Mott Generating Station in Calhoun County, Texas, authorizing Long Mott Energy to build four X-energy Xe-100 reactors at Dow's Seadrift site. The permit does not authorize operation, and fuel loading still requires a separate operating license. X-energy said Dow expects to consider a preliminary investment decision in 2027, and that full-scale construction would follow a final investment decision.
