The Tennessee Valley Authority successfully completed refueling and maintenance of Unit 2 at its Sequoyah Nuclear Plant, finishing the work ahead of schedule and under budget. The 83-day outage began on Oct. 15, 2012, and was completed on Jan. 6, the utility said. The Sequoyah Unit 2 refueling and maintenance outage and steam generator replacement project was scheduled for 90 days and budgeted for $376 million. Actual costs for this outage will be finalized in the coming weeks but the plant’s leadership team is confident the final cost will be under budget, TVA said.

"The steam generator replacement project was a complex feat of design, engineering and skilled craftsmanship," said TVA Chief Nuclear Officer Preston Swafford. "I’m extremely proud of the nuclear professionals who worked tirelessly to manage this outage at Sequoyah Unit 2 safely, with careful attention to costs and schedule, all while continuing to operate Unit 1 at 100 percent power."

Including Sequoyah plant personnel, contractors, craft, and other temporary workers, nearly 3,000 people were involved in the refueling and maintenance work, TVA said. Some 1,300 temporary workers were involved in the replacement of the four steam generators, which required approximately one million work-hours; all completed without a single lost-time incident, the utility said.
