Long Mott Generating Station: Plant configuration as described by the NRC: four Xe-100 reactors, 800 MW thermal (design disclosed)

What was reported

The facility, designated as LMGS, would be an 800 megawatts-thermal nuclear power plant comprising four X-Energy, LLC (X-energy) Xe-100 small modular high-temperature gas-cooled reactors and associated common facilities in Calhoun County, Texas.Regulator, government, developer and customer statements named in the Project Ledger · U.S. Nuclear Regulatory Commission (Federal Register, via govinfo.gov) statement · Aug 20, 2026 · Open the source ↗

What the evidence supports

That U.S. Nuclear Regulatory Commission (Federal Register, via govinfo.gov), the regulator, published the quoted statement. It records "design disclosed" for Plant configuration as described by the NRC: four Xe-100 reactors, 800 MW thermal under technical milestones only.

What remains unknown

A disclosed design is not a tested one. Performance at commercial scale, sustained output or independent confirmation, unless the quoted passage states them.
