NRC Investigates Safety Switches at Diablo Canyon Nuclear Power Plant
The federal Nuclear Regulatory Commission is conducting a special inspection at Diablo Canyon nuclear power plant to determine how two safety switches were misaligned, potentially impairing response in the event of a severe reactor accident.
The misalignment would have prevented two cooling water valves from being opened remotely from the reactor’s control room, forcing operators to be dispatched to manually open the valves.
