ONE ALARM SIREN INITIATED SPURIOUSLY
"At 1805 on 4/25/2010, Surry Power Station (SPS) Operations department began receiving reports from individuals in Surry County that at least one Early Warning System (EWS) siren was sounding. A subsequent review has confirmed that, at a minimum, Siren # 18 spuriously sounded six times over a period of approximately 20 minutes. Station personnel contacted the Virginia State Emergency Operations Center (EOC), in addition to Surry County dispatch for confirmation. Surry County dispatch reported that a number of calls were received for a sounding EWS siren. Neither the Virginia State EOC nor SPS Security received an alarm indicating that the siren was spuriously sounding. The Virginia State EOC has notified its Public Information Officer of the spuriously sounding siren. All plant conditions/parameters are normal, and-no releases to the environment have occurred.
"The site NRC Resident Inspector has been notified".
The emergency siren was on for approximately three hours before being locally disabled. There is still 100% coverage in the areas requiring siren notification.
