The Sequoyah Nuclear Plant is a nuclear power plant located on 525 acres (212 ha) located 7 miles (11 km) east of Soddy-Daisy, Tennessee, and 20 miles (32 km) north of Chattanooga, abutting Chickamauga Lake, on the Tennessee River. The facility is owned and operated by the Tennessee Valley Authority (TVA).

The plant has two Westinghouse pressurized water reactors. Sequoyah units 1 & 2, as well as their sister plant at Watts Bar, both have ice condenser containment systems. In case of a large loss-of-coolant accident, steam generated by the leak is directed toward borated ice which helps condense the steam creating a lower pressure, allowing for a smaller containment building.

The Tennessee Valley Authority (TVA) is a federally-owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similar to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth largest power supplier and largest public utility in the country.The TVA was created by Congress in 1933 as part of President Franklin D. Roosevelt's New Deal. Its initial purpose was to provide navigation, flood control, electricity generation, fertilizer manufacturing, regional planning, and economic development to the Tennessee Valley, a region which was significantly affected by the Great Depression relative to the rest of the nation. TVA was envisioned both as a power supplier and a regional economic development agency that would work to help modernize the region's economy and society, but later evolved primarily into an electric utility. It was the first large regional planning agency of the U.S. federal government and remains the largest.

Under the leadership of David E. Lilienthal, the TVA also became the global model for the United States' later efforts to help modernize agrarian societies in the developing world. Historically, the TVA has been documented as a success in its efforts to modernize the Tennessee Valley and helping to recruit new employment opportunities to the region. Despite its successes, historians have criticized its use of eminent domain with the displacement of over 125,000 Tennessee Valley residents for the agency's infrastructure projects.
