SCE&G Places Last of Six Super Modules for V.C. Summer Unit 2

CAYCE, S.C., Aug. 9, 2016 /PRNewswire/ -- In July and August 2016, South Carolina Electric & Gas Company (SCE&G), principal subsidiary of SCANA Corporation (NYSE: SCG), achieved two construction milestones by placing the final two super modules in the containment vessel of the V.C. Summer Unit 2 nuclear reactor.

Workers placed the CA03 super module in the nuclear island July 20 and the CA02 super module Aug. 5. Considered super modules because they are too large to transport and therefore require on-site assembly, CA03 and CA02 weigh approximately 250 tons and 60 tons, respectively. These structural steel modules are walls that are key components of the In-Containment Refueling Water Storage Tank (IRWST). The IRWST is a large, stainless steel-lined tank filled with water to absorb heat within containment and provide back-up cooling for the reactor vessel when the unit goes into operation. 

Prior to these heavy lifts, super modules CA01, CA04, CA05 and CA20 were placed in the Unit 2 nuclear island using one of the largest cranes in the world—a 560-foot tall heavy lift derrick.  Together these modules comprise the "big six" major structural components associated with Unit 2.

SCE&G and co-owner Santee Cooper are building two 1,117-megawatt Westinghouse AP1000 reactors in Fairfield County, S.C. Westinghouse is the contractor, and Fluor is the construction manager. Once the two units are complete, SCE&G anticipates that more than 60 percent of its generation will be non-emitting.
