The Virgil C. Summer Nuclear Generating Station occupies a site near Jenkinsville, South Carolina, in Fairfield County, South Carolina, approximately 20 miles (32 km) northwest of Columbia. The nuclear power station includes the decommissioned experimental Carolinas-Virginia Tube Reactor (CVTR) unit, just outside the site of the old town of Parr, SC. The CVTR was a 17 MWe, heavy water reactor. Its cooling water is supplied by the Monticello Reservoir (not to be confused with the Monticello Nuclear Generating Station in Minnesota), which is also used by a pumped storage (hydroelectric) unit. The plant utilizes a once-through cooling system.
This plant has one Westinghouse 3-loop Pressurized Water Reactor, which has received approval of a 20-year license extension, taking the license expiration of Unit 1 from 2022 to 2042. The plant is also in the process of constructing two Westinghouse AP1000 plants, which are currently on schedule to go into service in 2020.
The plant is named after Virgil Clifton Summer, the former Chairman and CEO of SCE&G.
V. C. Summer Unit 1 is a Westinghouse 3-loop Pressurized Water Reactor. The reactor first began commercial operation on January 1, 1984. The plant cost $1.3 billion to construct – 24 percent less per kilowatt than the average of 13 nuclear plants constructed over the same time period.
Unit 1 generates 2,900 MWt (Thermal Megawatts) of heat, supplying a net output of 966 MWe (Electric Megawatts) of electricity to the grid.
In 2001, the Summer unit operated at 79.9 percent of capacity, producing 6.76 billion kilowatt-hours of electricity. In 2007 it produced 8.48 billion kilowatt-hours, increasing its capacity factor to 100.2 percent.
