Vogtle nuclear expansion project marks multiple construction milestones
Latest construction achievements include Vogtle Unit 3 concrete 'super placement' and lift of 237-ton CA03 module
ATLANTA, Oct. 6, 2017
ATLANTA, Oct. 6, 2017 /PRNewswire/ -- Progress continues at the Vogtle nuclear expansion site near Waynesboro, Georgia. The latest milestones achieved over the past week include a critical concrete 'super placement' for Unit 3 and the lift of the 237-ton CA03 module for Unit 4.
The 71-hour continuous concrete placement included 1,844 cubic yards of concrete – enough to create a sidewalk more than six miles long. New concrete was poured in four key areas of the Unit 3 containment vessel – the refueling cavity, the bottom of the in-containment refueling water storage tank, the west steam generator cubicle walls and the pressurizer cubicle walls.
The 237-ton CA03 module for Unit 4 is a critical component and part of the In-Containment Refueling Water Storage Tank (IRWST). The IRWST is a 75,300 cubic foot tank that, once the units are operational, is filled with borated water and provides passive heatsink within containment and backup cooling for the reactor vessel.
Other significant milestones achieved at the Vogtle construction site over the past 30 days include the placement of the CA33 floor module for Unit 3. The module, weighing 35 tons, was delivered to the site from Greenberry Industrial in three sub-modules that were then welded together on site in the Vogtle Module Assembly Building. Additionally, workers placed the Vogtle Unit 4 deaerator inside the turbine building. The 148-foot, 300-ton deaerator functions like a water purifier, eliminating dissolved gasses such as carbon dioxide and oxygen from feedwater. Deaeration prevents corrosion, helping to reduce plant maintenance and operating costs.
More than 6,000 workers from across the country are on-site at Plant Vogtle today working to complete the nation's first new nuclear units in 30 years. New photos of progress at the construction site are available each month in the Plant Vogtle 3 & 4 Online Photo Gallery.
Vogtle Project Review Underway
Georgia Power owns 45.7 percent of the new units, with the project's other Georgia-based co-owners including Oglethorpe Power, MEAG Power and Dalton Utilities. On August 31, Georgia Power filed a recommendation with the Georgia Public Service Commission (PSC) to continue construction of the Vogtle nuclear expansion supported by all of the project's other co-owners. The recommendation was based on the results of a comprehensive schedule, cost-to-complete and cancellation assessment launched following the bankruptcy of Westinghouse in March. The Georgia PSC is expected to review the recommendation and make a decision regarding the future of the Vogtle 3 and 4 project as part of the 17th Vogtle Construction Monitoring (VCM) proceeding.

From the beginning of the Vogtle expansion, Georgia Power has worked to minimize the impact of the new units on customer bills. This effort continues during the Georgia PSC's review of the recommendation with the company recently announcing a conditional commitment of approximately $1.67 billion in additional loan guarantees for the project from the U.S. Department of Energy (DOE), as well as receipt of the first of multiple scheduled parent guarantee payments from Toshiba. Today, the total expected rate impact of the project remains less than the original estimate, after including anticipated customer benefits from federal production tax credits, interest savings from loan guarantees from the DOE and the fuel savings of nuclear energy.
Final approval and issuance of these additional loan guarantees by the DOE cannot be assured and are subject to the negotiation of definitive agreements, completion of due diligence by the DOE, receipt of any necessary regulatory approvals, and satisfaction of other conditions.
