Nuclear Energy

TVA’s nuclear plants contribute about 6,600 megawatts of electricity to the power grid, making the Nuclear Power Group an integral part of the seven-state power system.

About 30 percent of TVA’s power supply comes from its three nuclear plants: Browns Ferry, near Athens, Ala.; Sequoyah, in Soddy-Daisy, Tenn., and Watts Bar, near Spring City, Tenn. Those plants alone make enough electricity to power more than three million homes in the Tennessee Valley.

As nuclear performance improves across the industry, TVA Nuclear’s challenge is to continue its mission to ensure safe plant operations and achieve its vision of being the best multi-site nuclear power operator in the world.

Watts Bar Unit 2 Construction Project

The completion of Watts Bar Nuclear Plant Unit 2 continues to meet goals for schedule, safety, quality and cost. Once complete, the unit will produce the first new nuclear generation of the 21st century in the United States — generation that is low-cost and carbon-free.

Find out more about the project.

Bellefonte Nuclear Project

Changes in economic conditions, power demand and other external factors have caused TVA to reexamine the scheduled construction of the Bellefonte Nuclear Plant. In 2013, TVA developed a plan to reduce spending and staff at Bellefonte while continuing to protect the facility for future potential development. Based on work that has been accomplished to protect the Bellefonte asset and to develop an estimate to complete, TVA is focusing its resources on nearer term priorities.

Emergency Preparedness

TVA Nuclear’s operating standards and its highly trained workforce make it unlikely that an accidental release of radiation would occur. Nevertheless, emergency preparedness is an integral part of TVA’s nuclear power program.

The U.S. Nuclear Regulatory Commission offers information on national emergency response measures and public safety issues.


U.S. nuclear power plants, including TVA facilities, were safe and secure prior to Sept. 11, 2001, and they are even more so today, serving as a model for industrial security in America.
