NRC issues first U.S. construction permit for a BWRX-300 at TVA Clinch River

On 29 September 2026 the NRC permitted TVA to construct a GE Vernova Hitachi BWRX-300 small modular reactor near Oak Ridge. TVA said no construction date is announced yet.

Event date: · Published

GE Vernova Hitachi Nuclear Energy and the Tennessee Valley Authority both said on 29 September 2026 that the U.S. Nuclear Regulatory Commission issued a construction permit for a BWRX-300 at TVA's Clinch River site near Oak Ridge, Tennessee. GE Vernova said it is the first U.S. construction permit for a BWRX-300. TVA said it is the first U.S. utility permitted to build that design, and that this is only the second advanced-reactor construction permit ever issued in the United States.

The reactor is described as a 300 MW small modular reactor. TVA was explicit that no construction date has been announced, and that it is still negotiating cost sharing with industry partners.

Why it sits on the AI map: firm nuclear power is one long-dated answer to data-center load. A construction permit is a real regulatory step for GE Vernova's design in the United States. It is not megawatts online, and it is not a data-center offtake contract.

GE Vernova moves from gray to green. The compute-and-power tracker adds a support and stays at risk. TVA is not added as a company. Nothing turns red.

What would change the picture: a TVA construction start; an operating-license filing; or a named customer for Clinch River output.

What this doesn't prove

  • Construction permit only; not an operating license and not a construction start.
  • TVA said no construction date has been announced.
  • 300 MW is the design size in the releases, not online capacity.
  • Cost-sharing negotiations continue, per TVA.
  • The compute-and-power tracker gains a support and does not change status. TVA is not added as a company.

Next fixture

  • A TVA construction start or final investment decision.
  • Operating-license application timing.
  • Any named commercial offtake for Clinch River output.
