Title | One Emergency Warning Siren Energized for a Short Time |
Event Description | At 2245 [EDT] on 3/27/2013, Surry Power Station (SPS) Operations Department received a report from Virginia State Emergency Operations Center (VEOC) that a concerned citizen had called James City County (JCC) law enforcement to report that an Early Warning System (EWS) siren, #62 in James City County NW side of Route 682, was sounding. VEOC reported JCC police received call at 2240 [EDT] from a concerned citizen that an EWS siren was sounding. SPS Security contacted JCC police and subsequently reported that JCC police responded approximately 10 minutes later to the site of the siren, but the siren was no longer sounding. Maintenance will investigate in the morning. All plant conditions/parameters are normal and no releases to the environment have occurred.
The site NRC Resident Inspectors have been notified. This notification is being transmitted due to notification of other Government Agencies in accordance with 10CFR50.72(b)(2)(xi). The licensee also notified the state and local governments.
This report is being retracted based upon the following: On 3/28/13, an activation verification test was performed. The results of the test indicated EWS siren #62 did not activate. In addition, when a siren activates, the battery voltage decreases. A review of the battery voltage trend for siren #62 found no such decrease, verifying no activation occurred. Maintenance staff reported to the siren location and confirmed the siren did not activate. They also found no indication of tampering or intrusion. Three local homeowners were interviewed and stated they did not hear any siren activation. By all available indications, EWS siren #62 was functional and did not activate on 03/27/13. NRC Site Resident Inspectors have been notified of the retraction." Notified R2DO (McCoy). |
