‘Turbine tabletop’ completed for Vogtle nuclear expansion

Georgia Power announced Nov. 18 the latest construction achievement in the expansion of Plant Vogtle near Waynesboro, Georgia – the recently completed 15-hour continuous concrete pour for the Unit 3 “turbine tabletop.” The milestone marks the first turbine tabletop placement for a U.S. AP1000 new nuclear project.

The turbine tabletop is comprised of approximately 2,400 cubic yards, or 250 individual concrete trucks, of self-consolidating concrete measuring 10 feet-thick.  The tabletop serves as a pedestal for the Unit 3 generator and turbines and is designed to support the weight of the heavy components.

The expansion at Plant Vogtle is part of Georgia Power’s long-term, strategic plan for providing safe, clean, reliable and affordable energy for Georgians. Once units 3 and 4 join the existing two Vogtle units already in operation, Plant Vogtle is expected to generate more electricity than any other U.S. nuclear facility, enough to power more than one million homes and businesses. Southern Nuclear is overseeing construction and will operate the new units on behalf of Georgia Power, which owns 45.7 percent of the facility, and co-owners Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia and Dalton Utilities.

Georgia Power is the largest subsidiary of Southern Company (NYSE: SO), one of the nation’s largest generators of electricity.
