FAIRFIELD COUNTY — A major milestone passed Monday for the nuclear construction site in Fairfield County: South Carolina Electric & Gas Company, principal subsidiary of SCANA Corporation, completed placement of the nuclear island basemat for V.C. Summer Unit 2.
The structure represents the first new construction nuclear concrete to be poured in the United States in three decades.
“This is an exciting achievement for SCE&G, Santee Cooper, CB&I, Westinghouse Electric Company, and others who support our new nuclear project,” said Kevin Marsh, chairman and CEO of SCANA. “We recognize the significance of this event and appreciate the strong commitment to safety and collaboration demonstrated by all involved in reaching this milestone.”
Lonnie Carter, president and CEO of Santee Cooper, which co-owns V.C. Summer, agreed.
“This is a tremendous day for South Carolina as we work with SCANA to deliver new nuclear generation that will help ensure reliable, affordable electricity for decades to come,” Carter said. “We’ve come to this point through the diligent and conscientious attention to task by everyone involved, from our crews to the Nuclear Regulatory Commission.”
The basemat provides a foundation for the containment and auxiliary buildings that are within the nuclear island. Measuring 6 feet in thickness, the basemat required approximately 7,000 cubic yards of concrete to cover an area about 250 feet long and 160 feet at its widest section. Completed about 10 a.m. March 11, this 51.5-hour continuous pour of concrete covered a surface totaling 32,000 square feet.
About 1,550 workers are currently involved in constructing two new reactors at V.C. Summer, where Unit 1 has operated safely and reliably for 30 years. The new nuclear project will peak at about 3,000 workers over the course of three to four years.
The two 1,117-megawatt units will add 600 to 800 permanent jobs and bring SCE&G’s portfolio to 60 percent non-emitting sources when they start generating electricity in 2017 and 2018, respectively.
SCE&G is a regulated utility engaged in the generation, transmission, distribution and sale of electricity to approximately 670,000 customers in South Carolina.
