Title | Inadvertent Actuation of Emergency Warning Sirens |
Event Description | Exelon Generation has successfully tested the new emergency warning sirens installed in the 10-mile radius surrounding Peach Bottom Atomic Power Station. With approval from the Federal Emergency Management Agency (FEMA), Exelon Generation began transitioning to the new sirens on 10/1/13. At 11:31 am EDT, during the transition, a vendor technician inadvertently actuated the York County emergency warning sirens. The Sirens went through a full sounding of three minutes and then stopped alarming. The alarming sirens were not due to any condition at Peach Bottom. Exelon and York County have investigated the issue and found that the system worked properly. The cause of the inadvertent actuation was that a test signal was not given sufficient time to clear prior to putting the system in service after testing.
The NRC Resident Inspector has been informed. The licensee will issue a press release. |
