Virgil C. Summer Nuclear Generating Station
The Virgil C. Summer Nuclear Power Station occupies a site near Jenkinsville, South Carolina, in Fairfield County, South Carolina, approximately 20 miles (32 km) northwest of Columbia.
The 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. Its cooling water is supplied by the Monticello Reservoir, which is also used by a pumped storage (hydroelectric) unit. The plant utilizes a once-through cooling system.
South Carolina Electric and Gas was also in the process of constructing two Westinghouse AP1000 plants, which had been scheduled to go into service in 2020, but construction on these was abandoned in 2017.
The nuclear power station also 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.
The plant is named after Virgil Clifton Summer, the former chairman and CEO of SCE&G.
In August 2023, Dominion Energy applied for another 20-year license extension for Unit 1 beyond 2042, which as of October 2023 is under consideration by the NRC.
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 (equivalent to $4 billion in 2024)– 24 percent less per kilowatt than the average of 13 nuclear plants constructed over the same time period.
Unit 1 generates 2900 MWth (Thermal Megawatts) of heat, supplying a net output of 966 MWe (Electric Megawatts) of electricity to the grid.
