Safe nuclear energy is integral to our mission of powering the economic prosperity of the Tennessee Valley.

Our nuclear plants generate enough low-cost, clean and reliable electricity to power about a third of our customers—more than 3 million homes and businesses—with work underway to increase that capacity by bringing Unit 2 at Watts Bar Nuclear Plant into operation. With a top priority of safety and security, nuclear power is key to our vision of leading the nation in the production of affordable, carbon-free electricity, and our mission of providing clean electricity for the Tennessee Valley.

Our Plants

We operate three nuclear plants that generate 6,700 megawatts of electricity each day:

Why Nuclear?

  • Nuclear power is the best option for generating large amounts of electricity that's safe, clean, reliable and cost-effective—allowing us to keep our rates competitive and reliability high.
  • Nuclear power is environmentally friendly and doesn't produce harmful greenhouse gas emissions.
  • Nuclear power plants run economically, second only to hydroelectric power in low operating costs. Combined with our renewable energy and energy efficiency efforts, increasing nuclear generation allows us to reduce reliance on coal, decrease air emissions and provide reliable, affordable power to the people of the Tennessee Valley.

Safety—Our Top Priority

Our nuclear plants have multiple safety systems in place to keep our workforce and the communities we serve safe. Safety systems include physical barriers that protect against radiation release, and layer upon layer of redundant and diverse back-up power systems to keep reactors sufficiently cooled—even in the most extreme or unlikely of events. 

The nuclear industry is among the most thoroughly tested and regulated industries in the world. Our plants operate with oversight by the U.S. Nuclear Regulatory Commission (NRC), which has inspectors physically stationed at each site.

Industry organizations, such as the Institute of Nuclear Power Operations and the World Association of Nuclear Operators, work to ensure that the industry achieves the highest level of safety and reliability through plant evaluations, training, accreditation, events analysis and information exchange.

U.S. nuclear plants are well-designed to withstand natural disasters like floods, droughts, earthquakes and hurricanes—as well as man-made threats such as aircraft crashes. After the event at Fukushima in Japan, the NRC required all nuclear plants to install additional backup safety equipment, known as FLEX, to protect plants from even more extreme events—including “stacked” events during which one disaster follows another.

In 2014, the industry opened national response centers in Memphis and Phoenix that can deliver additional safety equipment and resources to any U.S. nuclear power plant within 24 hours.

TVA nuclear regularly reviews nuclear successes and setbacks across the globe, and we use that knowledge to update our equipment, procedures and training to the highest standards.

Emergency Preparedness

While our strong commitment to safety, high operating standards and highly trained workforce make a radiation leak or other incident unlikely, emergency preparedness is central to TVA Nuclear operations.

Those preparations include emergency procedures, supply checklists, evacuation instructions and evacuation routes.
