Reactor vessel cavity placed at Plant Vogtle nuclear Unit 3

It was lifted into place using a 560-foot tall heavy lift derrick, one of the largest cranes in the world

Georgia Power completed a milestone in the construction of Plant Vogtle units 3 and 4 — the placement of the CA-04 module in the Unit 3 nuclear island. The module, also known as the reactor vessel cavity, will house the Unit 3 reactor vessel and is a critical module for the project.

It is comprised of five sub-modules, weighing about 64,000 pounds, and is 27 feet tall and 21 feet wide. It was lifted into place using a 560-foot tall heavy lift derrick, one of the largest cranes in the world.

The placement of this component is the latest illustration of the continued progress of the construction of the two new nuclear units at Plant Vogtle near Waynesboro, Georgia. The new units, using AP1000 technology, are among the first nuclear units being built in the U.S. in 30 years.

In November, the project marked another significant milestone with the placement of the basemat structural concrete for the Unit 4 nuclear island. The concrete placement, which encompassed about 7,000 cubic yards of concrete, will serve as the foundation for all of the Unit 4 nuclear island structures.

Southern Nuclear, a unit of Southern Co., is overseeing construction and will operate the two new 1,100 MW AP1000 units for Georgia Power and co-owners Oglethorpe Power Corp., the Municipal Electric Authority of Georgia and Dalton Utilities. Georgia Power owns 45.7 percent of the new units.
