SCE&G Uses World's Largest Crane to Lift and Set 2.4-Million Pound Module; Progress Also Made With Shield Building Construction

CAYCE, S.C., July 23, 2015 /PRNewswire/ -- South Carolina Electric & Gas Company (SCE&G), principal subsidiary of SCANA Corporation (NYSE: SCG), and its partners placed on July 23 the 2.4-million pound CA01 module that will house a number of major components in the first of two new nuclear plants at the V.C. Summer site.

"Successful placement of this major module demonstrates the progress being made with our new nuclear units that are under construction at V.C. Summer," said Kevin Marsh, SCANA chairman and CEO. "Adding more nuclear energy to our generation mix is the best solution for providing South Carolina large-scale energy that is clean, safe, and reliable, as well as cost-effective over the long-term."

This is the first Westinghouse AP1000 module of its kind to be placed in the U.S., and it is the heaviest lift on the V.C. Summer nuclear construction site. One of the world's largest cranes, a heavy lift derrick that stands approximately 560-feet tall, was used to lift this massive module.

The CA01 module is a multi-compartment steel structure within the Unit 2 containment vessel. It is approximately 90 feet long, 95 feet wide, and 80 feet high. Considered a super module because it is too large to transport, CA01 was assembled on the construction site in a 12-story Module Assembly Building.

Lonnie Carter, president and CEO of Santee Cooper, co-owner of V.C. Summer, said, "The successful placement of the CA01 module marks a significant milestone for this project. The new nuclear units at V.C. Summer remain a critical component of Santee Cooper's long-term plan to diversify our generation mix and to continue to provide low-cost, reliable and environmentally-sound electricity to our customers."

In addition to this significant milestone, another milestone was achieved just a few days before for V.C. Summer Unit 2. The first six-panel course of nearly 170 shield building panels was placed on July 17. Weighing 30,000 pounds and spanning 40 feet long, each panel will be welded together. Concrete will then be poured inside the panels to create the shield building. When complete, this reinforced concrete structure will surround the containment vessel for another layer of safety.

Approximately 3,500 CB&I and Westinghouse personnel and subcontractors are employed on the nuclear construction site in Fairfield County, S.C., where V.C. Summer Unit 1 has operated safely and reliably for more than 30 years and V.C. Summer Units 2 and 3 are being built.

The two 1,117-megawatt 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.

PROFILE 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. The company also provides natural gas service to approximately 342,000 customers throughout the state. More information about SCE&G is available at
