Tennessee Valley Authority announced Thursday the safe and successful completion of the Unit 1 refueling outage at Sequoyah Nuclear Plant.
Unit operators will be raising power output over the next couple of days until Unit 1 is at full capacity.
Ninety-three fuel assemblies were replaced during the outage. Workers tested more than 350 valves and pumps. A total of 11,500 activities were completed, including 1,200 scaffold and insulation activities.
“The nuclear professionals at Sequoyah worked tirelessly to manage the Unit 1 outage safely, while continuing to operate Unit 2 at 100 percent power,” said John Carlin, Sequoyah site vice president. “The work accomplished during the outage will ensure safe and reliable operations at Sequoyah.”
Approximately 950 contractors supplemented Sequoyah’s employees during the outage, adding a more than $5 million boost to the local economy.
Sequoyah Unit 1 is one of six nuclear power generating units operated by TVA at three facilities. At full capacity, Sequoyah’s 1,160-megawatt Unit 1 and 1,160-megawatt Unit 2 combined produce enough electricity for more than 1.3 million homes. TVA also operates three units at the Browns Ferry Nuclear Plant in Athens, Ala., and one unit at the Watts Bar Nuclear Plant near Spring City, Tenn., where a second unit is scheduled for completion in December 2015.
The Tennessee Valley Authority is a corporate agency of the United States that provides electricity for business customers and local power distributors serving 9 million people in parts of seven southeastern states. TVA receives no taxpayer funding, deriving virtually all of its revenues from sales of electricity. In addition to operating and investing its revenues in its electric system, TVA provides flood control, navigation and land management for the Tennessee River system and assists local power companies and state and local governments with economic development and job creation.
