SODDY-DAISY, Tenn. – The Tennessee Valley Authority's Sequoyah Nuclear Plant Unit 2 began a scheduled refueling and maintenance outage on Monday after completing 438 consecutive days of operation.
"Every 18 months, one of the Sequoyah units is taken offline so fuel can be replaced and maintenance can be safely performed on key equipment and systems," said John Carlin, Sequoyah Nuclear Plant vice president. "Sequoyah's Unit 1 will continue to safely operate and generate electricity during the Unit 2 refueling.
"This work will ensure that both Sequoyah units can continue to safely generate reliable, clean and low-cost energy for millions of people in the Tennessee Valley."
More than 600 contractor workers will supplement Sequoyah's employees during the refueling outage. The project will involve more than 150,000 work-hours until the outage is completed.
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 late 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.
