Sequoyah Unit 1 Safely Completes Scheduled Refueling, Maintenance Outage

May 18, 2015

SODDY-DAISY, Tenn. – The Tennessee Valley Authority’s Sequoyah Nuclear Plant has returned its Unit 1 reactor to operation after successfully completing more than 10,000 activities designed to enhance the safety and reliability of the unit.

“Although safely refueling the reactor was our key activity, the primary focus is always on improving the safety and reliability of plant equipment,” said John Carlin, site vice president. “Team members refurbished or replaced more than 500 individual valves, electrical breakers and motors, some of which can only be accessed when the unit is offline.”

Unit 1 returned to operation on Saturday, May 16.

In addition to refueling, the site successfully completed a detailed 10-year inspection of the reactor vessel and its internal components. The team also added a number of enhancements to the station’s emergency operation capabilities.

“The work we’ve done over the past few weeks is an important part of our commitment to provide all of the benefits of carbon-free, reliable electricity to our customers while ensuring safety for the public and our employees,” Carlin said.

At full capacity, Sequoyah’s two generating units provide a combined 2,200 megawatts of electricity, enough to power 1.3 million homes across the Tennessee Valley. 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 currently nearing completion 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.
