Caption: Plant Vogtle's CA04 module inside the Unit 4 nuclear island
Georgia Power, a unit of Southern Co. (NYSE: SO), placed the CA04 module inside the Unit 4 nuclear island at the Plant Vogtle project site.
The CA04 module, also known as the reactor vessel cavity, is comprised of five sub-modules and will house the Unit 4 reactor vessel. The 32-ton component was assembled onsite in the modular assembly building, moved to the nuclear island as one piece and lifted into place by a heavy lift derrick.
There are more than 5,000 workers on site where two 1,100-MW Westinghouse AP1000 reactors are under construction. Georgia Power said workers also completed the concrete placement for the Unit 3 Annex Building basemat, the last of 12 separate water boxes within the Unit 3 turbine island and the arrival of multiple pieces of major equipment onsite for Unit 4. Also completed were transmission upgrades and installations at the site in preparation of connecting the new units to the Georgia grid.
The two new units will be co-owned by Georgia Power, Oglethorpe Power Corp., the Municipal Electric Authority of Georgia and Dalton Utilities.
