| Title | Loss of Emergency Sirens Due to Power Outages Caused by High Winds |
| Event Description | At approximately 0800 on 09/15/2008, it was determined that 55 of 119 Beaver Valley Power Station (BVPS) Emergency Offsite Sirens were inoperable. The apparent cause is loss of power to the sirens due to numerous power outages in the surrounding area. High winds from the remnants of Hurricane Ike passed through the surrounding area overnight. The weather has since returned to normal conditions. BVPS has validated that backup route alerting capability is in place for Columbiana County, Ohio and Hancock County, West Virginia. Beaver County, Pennsylvania is in process of verifying backup route alerting capability for the affected areas. This event is being reported as a Loss of Emergency Preparedness Capabilities pursuant to 10CFR50.72(b)(3)(xiii).
The NRC resident inspector has been notified. Updates on the status of siren restoration will be provided to the NRC resident inspector on an ongoing basis. Periodic updates to the NRC Headquarters' Operations Center will also be provided.
