The development of Georgia Power’s Vogtle nuclear expansion reached a new milestone this month with the placement of the Unit 3 pressurizer, which will provide pressure control inside the reactor coolant system once the unit begins operating.
The 225,000-pound pressurizer for Vogtle Unit 3 arrived via rail at the construction site in August 2014. It was fabricated in Italy and shipped to the Port of Savannah, before being loaded onto a railcar for the final leg of its journey.
Other recent milestones at the only new nuclear units under construction in the United States include 1,300 cubic yards of concrete placed in the Unit 4 containment vessel and the placement of the last of the “big six” modules – the Unit 4 CA02 module, which will make up the in-containment refueling water storage tank.
Additionally, Georgia Power has released an aerial tour of the expansion, which allows the user to zoom in on key parts of units 3 and 4, including the containment vessels, turbine buildings and cooling towers. The tour is accessible here.
