Tennessee Valley Authority Seeks Permit for Small Nuclear Reactor, Aiming to Accelerate Next-Generation Power

Strategic Insights -

For the first time in the United States, a utility has asked federal regulators for a permit to build a small nuclear reactor. The Tennessee Valley Authority, the nation's largest public power company, has submitted a construction permit application to the U.S. Nuclear Regulatory Commission for a small, modular nuclear reactor at its Clinch River site in Oak Ridge, Tennessee. The move aims to demonstrate the feasibility of next-generation nuclear power and pave the way for other utilities to follow.

Key Takeaways:

  • The TVA is seeking to build a small, modular nuclear reactor at its Clinch River site in Oak Ridge, Tennessee, with the goal of demonstrating the feasibility of next-generation nuclear power and accelerating its development.
  • The reactor will be built using GE Hitachi's design for a small modular reactor that uses light water, similar to large U.S. commercial reactors.
  • The TVA plans to provide 300 megawatts of power, which is enough for about 175,000 homes, once the reactor is operational around 2032.
  • The utility has provided $350 million in funding for its program to develop and fund small modular nuclear reactors, aiming to reduce planet-warming greenhouse gas emissions.
  • The decision may be the start of a trend, as the U.S. does not have any next-generation reactors operating commercially, and the NRC is currently reviewing applications from companies wanting to build these reactors.
  • The project's cost estimates are in the same range as the $6.1 billion cost for the first four small nuclear reactors in Ontario, Canada, but the TVA is seeking partners to help with the initial costs.
  • Environmental groups have expressed skepticism about the feasibility and cost-effectiveness of small modular reactors, citing the need for proven renewable sources like solar rooftops, battery storage, and wind power.

Statistics:

  • The TVA plans to increase electricity demand by up to 26 gigawatts by 2035, enough to power roughly 15 million homes.
  • The reactor will provide 300 megawatts of power, enough for about 175,000 homes.
  • The NRC has already said the Clinch River site is suitable for a new nuclear plant, with enough room for a total of four small reactors.
  • The TVA has provided $350 million in funding for its program to develop and fund small modular nuclear reactors.
  • The total investment in small modular reactors in the U.S. is expected to reach $900 million, with the Biden administration announcing the funding last year.
