The power plant, which is located in southwestern Wake County, had been offline for more than one week.
It powered back up around 10 a.m. Thursday.
The first shutdown was occurred on August 11 when workers noticed a water leak. That problem was fixed.
But when they tried to restart the plant Tuesday, it was shut down again after another problem was discovered. The Nuclear Regulatory Commission, the agency that monitors the plant, said the shutdowns posed no safety risks.
