SPURIOUS ACTUATION OF ONE OFFSITE EP SIREN

"At 14:10 on 09128/2002, the Palo Verde Unit 1 Control Room was notified of a spurious actuation of one siren. The siren is located near Southern and Palo Verde Roads. This siren provides emergency notification to approximately 39 Members of the Public.

"No press release is planned at this time, however, the event is being reported due to inquiries from the Maricopa
County Department of Emergency Management to troubleshoot the siren and notification of the siren actuation to the
Maricopa County Sheriffs Office.

"Personnel have been dispatched to turn off the siren.

"There is no event in progress and no risk to the health and safety of the public. Members of the public within audible
range of the siren may have a concern for their radiological health and safety.

"Unit 1 is at approximately 0% power In Mode 5 at the start of its scheduled refueling outage. Unit 2 is at approximately 99% power in Mode 1 at normal operating temperature and pressure. Unit 3 is at approximately 99% power in Mode 1 at normal operating temperature and pressure.

"The NRC Resident Inspector has been informed of the siren actuation and this ENS notification. Note: The checkbox for OTHER GOV AGENCIES is referring to the Maricopa County agencies discussed above."
