LA Times (9/8/2011):
The blackout affecting large swaths of San Diego County led to a shutdown of two reactors at the San Onofre nuclear power plant.
Gil Alexander, a spokesman for Southern California Edison, said the power outage did not cause any safety issues. Alexander said a fluctuation in power caused the reactors to shut down at 3:38 p.m. but that the overall plant continues to have power.
He said the system worked as it was supposed to during a loss of power.
