Sequoyah nuclear power plant has increased oversight

Sequoyah nuclear power plant increased oversight Tennessee Valley Authority Nuclear Regulatory Commission Watts Bar nuclear power plant

Tennessee Valley Authority (TVA)’s 2,357 MW Sequoyah nuclear power plant in Tennessee will have increased oversight from the U.S. Nuclear Regulatory Commission (NRC) because of violations for analyzing and preparing for potential flooding. The plant is located on Chickamauga Lake, which is part of the Tennessee River system.

NRC staff held a conference with TVA officials to discuss preliminary inspection findings in the flood protection area. The staff determined that TVA did not establish adequate flood protection for the potential failure of upstream dams. That violation was classified as white, meaning it was low to moderate safety significance. NRC also found that TVA did not take necessary measures to keep water from entering the intake pumping station in the event of a flood. That violation was also classified as white.

The plant was also cited for not notifying the NRC within eight hours of discovery that the potential failure of the upstream dams and subsequent potential flooding.

NRC identified similar violations at TVA’s Watts Bar nuclear power plant in Tennessee.
