The federal nuclear regulator has approved Tennessee Valley Authority to build what is described as the first U.S. small modular reactor project. The decision gives TVA a permit to proceed at Clinch River Nuclear Unit 1.
TVA is the power producer behind the project, and the permit covers construction at the Clinch River site. The report says the approval is a project win, but it does not resolve the next steps needed to move forward.
According to the source, project execution still depends on contractor authorizations, long-lead equipment orders and future board approvals. Those items remain unresolved for Clinch River Nuclear Unit 1.
The report was published by Engineering News-Record on Sept. 30, 2026. Architecture Radar is relying on that reporting and the structured fields provided with the source.
The permit changes the project’s status from regulatory review to execution planning, with procurement and approvals still ahead before work can advance further.
