"On August 29, 2005 at about 1045 PDT, San Onofre Nuclear Generating Station, Unit 3, removed a portion of the Safety Parameter Display System (SPDS) and the Emergency Response Data System (ERDS) from service for a planned upgrade to ensure long-term reliability and improve the human-machine interface. This work is expected to complete within seven days.
"The SPDS emergency assessment function at San Onofre is implemented by a combination of the Qualified Safety Parameter Display System (QSPDS) and the Critical Function Monitoring System (CFMS). The QSPDS portion, which provides emergency assessment capability to plant operators in the control room, will remain functional. The CFMS portion, which receives input from the QSPDS, implements the ERDS and communicates data to the Technical Support Center and Emergency Offsite Facility. Only the CFMS and ERDS are impacted by this upgrade.
"This planned CFMS outage is being reported in accordance with10CFR50.72(b)(3)(xiii) as a courtesy notification even though only a portion of the SPDS will be removed from service and preplanned compensatory measures will be in place for the duration of the work.
"At the time of this report, Unit 2 and Unit 3 were operating at about 99 percent and 100 percent power, respectively. The NRC Resident Inspectors will be notified of this occurrence and will be provided with a copy of this report." |

"Due to winds associated with hurricane Katrina, power has been loss to 17 of the 43 emergency sirens. This places the number of required sirens less than the operability rate of 75%. Additional sirens may be lost as the storm passes through the area. A recovery plan will be developed and implemented once weather conditions allow.
"Notification per ENS [the Emergency Notification System] could not be accomplished and notification was made per commercial phone lines. This event notification documents loss of ENS also which was verified by NRC."
The licensee has notified State and local authorities and the NRC Resident Inspector of this event. |

"On August 29, 2005 at approximately 10:30 Mountain Standard Time (MST), the Palo Verde Emergency Preparedness Department identified an inoperable single siren (#18). The siren was vandalized by stealing the internal battery. The affected siren is estimated to impact approximately 131 members of population in the emergency planning zone (EPZ) within 5 miles. This call is being placed due to the relatively large segment of the population affected and the uncertainty of the length of time that will be needed to restore the siren to operable condition. The Palo Verde Emergency Plan (section 6.6.2.1) has a contingency for dispatching Maricopa County Sheriff's Office (MCSO) vehicles with loud speakers to alert persons within the affected area's) when sirens are inoperable.
"Maricopa County and State agencies have been informed to implement the MCSO notification if a need arises.
"There are no events in progress that require siren operation."
