Dow and X-energy apply to the NRC to build four Xe-100 reactors at Seadrift, Texas

X-energy/Xe-100 at Long Mott (Dow Seadrift)

Dow and X-energy submitted a construction permit application to the NRC for the Long Mott Generating Station at Dow's Seadrift, Texas site, which would use Xe-100 small modular reactors to provide power and industrial steam to Dow's manufacturing operations. The Xe-100 design features passive safety and proprietary TRISO-X fuel; approval could take ~30 months with construction potentially beginning in the late 2020s and startup expected in the early 2030s.

• Construction permit application submitted 31 March 2025 to the NRC.
• Xe-100 reactors feature passive safety and TRISO-X proprietary fuel.
• Approval timeline: ~30 months; nuclear construction could start late 2020s.
• Supported by DOE's Advanced Reactor Demonstration Program.
