One reactor at Dominion Virginia Power's North Anna power plant remains offline after being hit by a series of lightning strikes.
Nuclear Regulatory Commission spokesman Joey Ledford says there two dozen lightning strikes hit the North Anna 2 reactor site Wednesday. The last strike caused a surge that tripped the electronic reactor protection system.
Dominion Virginia Power spokesman Rick Zuercher says auxiliary instruments that monitor reactor coolant temperature were damaged.
According to the commission's website, the reactor was still shut down Friday morning.
Dominion Virginia Power says it's the fourth time lightning strikes have shut down the reactor since 1998.
