On September 29, 2026, the Nuclear Regulatory Commission is expected to issue a formal construction permit for a new small nuclear reactor in Tennessee. The Tennessee Valley Authority plans to build the 300-megawatt system following this regulatory approval.
Why it matters
The authorization enables the development of a 300-megawatt nuclear project, marking a shift toward small-scale modular power systems. This development follows years of planning for alternative nuclear infrastructure within the state's energy grid.
The planned Tennessee project will utilize a 300-megawatt nuclear system. This design represents a move toward smaller capacity units compared to traditional gigawatt-scale reactors.
The players
Nuclear Regulatory Commission
A federal agency responsible for regulating nuclear power plants and the civilian use of nuclear materials.
Tennessee Valley Authority
A federally owned electric utility corporation that provides power and energy infrastructure across the Tennessee region.
The details
The Nuclear Regulatory Commission issues construction permits as part of a formal review process for reactor installation. These permits authorize the construction phase of the project, allowing the Tennessee Valley Authority to begin the assembly of the 300-megawatt system.
Timeline

The Tech Race
This project aligns with national efforts to deploy small-scale nuclear technologies to improve grid reliability. It follows the established SMR licensing framework designed to standardize the deployment of modular reactor units.
The issuance of this permit clears the path for the Tennessee Valley Authority to begin onsite physical construction. Residents should monitor future project updates for details on local infrastructure upgrades or shifts in power generation capabilities.
The takeaway
This permit marks the transition of the Tennessee project from the planning phase to authorized construction. Interested parties should watch for the official publication of the permit terms on September 29, 2026.
