The Tennessee Valley Authority’s Sequoyah Nuclear Plant Unit 1 has begun a scheduled refueling and maintenance outage after producing more than 13.6 billion kilowatt-hours of carbon-free electricity over the past 18 months, including one period of 474 consecutive days of full power operation.
“Outages create different kinds of tasks for the team but our focus remains exactly the same ̶ performing each job safely and with the highest levels of quality,” said John Carlin, site vice president. “Unit 2 will remain online during the Unit 1 outage, so all activities are carefully coordinated to maintain public and employee safety.”
An additional 950 TVA and contract employees will supplement the site’s regular staff during the outage, which began Saturday, April 11. More than 12,000 work activities are planned, including loading new fuel assemblies, performing inspections of reactor components, maintaining plant equipment and installing unit enhancements.
“We intend to take full advantage of this opportunity to improve the reliability of the plant,” said Carlin. “It will help us pursue our goal of sustained top industry performance while providing safe, reliable power to the people of the Tennessee Valley.”
At full capacity, Sequoyah’s two generating units provide a combined 2,200 megawatts of electricity, which can power 1.3 million homes. TVA also operates three units at the Browns Ferry Nuclear Plant near Decatur, Alabama, and one unit at the Watts Bar Nuclear Plant near Spring City, Tennessee. A second unit is being built at Watts Bar and is scheduled for fuel load later this summer.
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.
