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.
