Construction achievements include the placement of 200 cubic yards of concrete to fill the walls of the new shield building panels for Unit 3; placing more than 1,800 cubic yards of concrete to fill the walls of the CA20 module; installing component cooling water pumps on the Unit 3 turbine building; placing concrete for the elevated roof slab on the southwest corner of the Unit 4 turbine building and completing vertical seam welds on placed shield building panels for Unit 3.
Construction of the two Westinghouse AP1000 reactors is now more than 60 percent complete based on contractual milestones. The projected overall peak rate impact of the Vogtle expansion project is significantly less than when the project was originally certified due to lower financing rates and other benefits. Unit 3 is expected to be completed in June 2019, and Unit 4 in June 2020.
