The license for one reactor would then run until 2053 with the other running until 2054, the Greenville News reported.
The extensions are part of Duke Energy’s plans to seek 20-year license extensions at its five reactors at three sites in South Carolina, utility spokesperson Rita Sipe said.
The utility also owns the Robinson Nuclear Plant in Hartsville and jointly owns the Catawba Nuclear Station near Rock Hill.
The process to renew the licenses will take at least 18 months and involve public comment periods, officials said.
Older nuclear plants are good bets to get license renewals because their construction costs have already been paid off and the technology and materials used in the plants and reactors have not dramatically changed, said Travis Knight, a University of South Carolina professor and director of its nuclear engineering program.
Regulators will review physical components like the concrete in the structures to make sure they are still strong, functional and safe, Knight said.
Also, the technology is not available yet for renewable energy sources to match the amount of power generated by a nuclear plants, Knight said.
Only two states generate more nuclear power than South Carolina, which allows utilities in the state to sell the excess electricity.
