Dow's Long Mott secures NRC construction permit for proposed advanced nuclear plant in Texas
- The NRC approved the Construction Permit Application for the proposed Long Mott Generating Station in Seadrift, Texas.
- The project is developed by Long Mott Energy, LLC (a Dow subsidiary) in collaboration with X‑energy under the U.S. Department of Energy's Advanced Reactor Demonstration Program.
- The facility is intended to provide zero‑carbon electricity and high‑temperature steam to Dow's UCC Seadrift Operations site, replacing existing energy and steam assets nearing end‑of‑life.
- Receipt of the construction permit does not commit Dow to build; further milestones include engineering/design finalization and Board review, with construction possible later this decade and startup early next decade if approved.
Regulatory milestone
The U.S. Nuclear Regulatory Commission approved the Construction Permit Application for the proposed Long Mott Generating Station in Seadrift, Texas, following a comprehensive review of the proposed facility, site characteristics, construction plans, environmental considerations and safety‑related information submitted by Dow and X‑energy.
Project purpose and partners
The project is being developed through Long Mott Energy, LLC (a wholly owned Dow subsidiary) in collaboration with X‑energy under the Department of Energy's Advanced Reactor Demonstration Program. It is intended to provide zero‑carbon electricity and high‑temperature steam to Dow's UCC Seadrift Operations site, replacing existing energy and steam assets near end‑of‑life, and is expected to be the first advanced nuclear project deployed at an industrial site in North America.
Next steps and timeline
Receipt of the construction permit does not represent a final decision to proceed with construction. Several milestones remain before potential construction activities could begin, including continued engineering and design finalization and review by Dow's Board of Directors; if approved, construction could begin later this decade, with startup early next decade.
