Title | Emergency Notification System Sirens Inadvertantly Actuated for 3 Minutes |
Event Description | At 0849 [EST] on 1/31/2011 the Emergency Notification System Sirens inadvertently actuated for 3 minutes. We [Davis Besse] have been informed by Ottawa county that the actuation signal appears to have originated from the Ottawa County Sherriff's dispatcher console. They also informed Davis Besse that Vendor Support is being requested to assist in the determination of the cause. The Ottawa County Emergency Management Agency is planning a news release for the inadvertent actuation.
The Emergency Notification System sirens were secured and are considered to be operable. The licensee notified the NRC Resident Inspector. |
