Sequoyah Nuclear Unit 1 Begins Scheduled Refueling Outage

 

Tennessee Valley Authority’s Sequoyah Nuclear Plant Unit 1 began a scheduled refueling outage on Monday after completing 509 consecutive days of operation.

The Unit 1 reactor generated 14.8 net gigawatt hours since its last refueling about 18 months ago.

During the refueling outage, 93 fuel assemblies will be replaced and maintenance will be performed that cannot be done while the unit is online. Sequoyah’s Unit 2 will continue to operate and generate energy as usual.

 More than 800 contractor workers will supplement Sequoyah’s employees during the refueling outage. The project will involve more than 160,000 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.
