Steam generator replacement completed at nuclear power plant

Tennessee Valley Authority (TVA) completed a refueling and maintenance outage at Unit 2 of the 2,320 MW Sequoyah Nuclear Plant in Tennessee on Jan. 11. The project was finished on time and under budget, TVA said.

The 83-day, $376 million outage began on Oct. 15, 2012 and was completed Jan. 6. It was initially scheduled to last 90 days. The work included replacing four steam generators along with normal refueling. TVA completed similar replacement projects at Sequoyah Unit 1 in 2003 and Watts Bar Nuclear Unit 1 in 2006.

TVA officials said they are finalizing actual costs to determine how much was actually spent on the project.

Unit 1 continued operations throughout the shutdown.
