COURTESY NOTIFICATION REGARDING FAILURE OF THE 'A' PHASE BUS POTENTIAL DEVICE IN THE SWITCHYARD [outside the Protected Area but inside the Owner Controlled Area]
The following text is a portion of an E-mail received from the licensee following a courtesy telephone call to the NRC Operations Center:
"On June 24, 2001, at about 1103 PDT, the 'A' Phase Bus Potential Device failed in the southeast section of the San Onofre switchyard. (This device performs a monitoring function only and plant operations were unaffected). The failure resulted in debris on the road adjacent to the switchyard (old Highway 101). The resulting fire was extinguished by 1140 PDT. One individual was in the switchyard at the time of this occurrence but was not injured. No offsite personnel were injured."
"As a precautionary measure, the San Onofre Security force notified the San Diego branch of the FBI and the FBI chose to respond to San Onofre. Before arriving onsite, SCE again contacted the FBI indicating they did not need to respond to this event and they did not."
"The NRC Resident Inspectors have been notified of this occurrence and will be provided with a copy of this report. At the time of this occurrence, San Onofre Unit 1 remained permanently shutdown; San Onofre Units 2 and 3 were both at about 100 percent power and remain at about 100 percent power."
HOO NOTE: The licensee (Ed Scherer and Clay Williams) stated that the notification to the FBI was not required and that it was only a courtesy notification. The FBI serves as local law enforcement.
