CA04, which is the reactor vessel cavity that will house the Unit 3 reactor vessel and related components, was placed on the containment vessel bottom head on June 29. Just one day before, the Unit 3 reactor vessel arrived on site from the Port of Charleston. The reactor vessel was transported on a Schnabel specialty railcar, which is designed to carry heavy loads.
Standing approximately 27 feet tall and stretching 21 feet wide, CA04 is considered a super module because it is too large to transport fully assembled. Its sub-modules were fabricated at SMCI in Lakeland, Fla., and then welders completed final fabrication on the V.C. Summer construction site in the 12-story Module Assembly Building. CA04 was then lifted into place by one of the world's largest cranes-a heavy lift derrick that stands about 560-feet tall. Once CA04 is fully encased in concrete, the reactor vessel will be lowered into it and mounted on top.
These milestones and many others were previously achieved on V.C. Summer Unit 2, which continues to make progress. Follow construction progress by visiting SCE&G on Flickr and YouTube for nuclear construction photos and videos.
Approximately 3,500 Chicago Bridge & Iron and Westinghouse personnel and subcontractors are employed on the nuclear construction site in Fairfield County, S.C., where Unit 1 has operated safely and reliably for more than 30 years and Units 2 and 3 are being built. State-owned utility Santee Cooper is the co-owner.
The two 1,117-megawatt AP1000 units will add approximately 800 permanent jobs when operational. Once the two units are complete, SCE&G anticipates its generation mix will be about 30 percent nuclear, 30 percent natural gas, and 30 percent scrubbed coal, with the balance in hydro, solar and biomass.

SCE&G is a regulated public utility engaged in the generation, transmission, distribution and sale of electricity to approximately 692,000 customers in South Carolina.
