Title | Emergency Sirens Inadvertently Actuate |
Event Description | Spurious siren activation at Point Beach affects associated sirens (P001 - P010) at Kewaunee Power station. A separate 50.72 notification is to be made for Kewaunee per procedure GWP-11.08.04.
At 1216 CDT, 09/10/10 station EP personnel notified the control room staff that an inadvertent activation of EP sirens occurred for the Point Beach Station at 1520, 09/09/10. This information was relayed to the EP personnel via Manitowoc County EP personnel, who had received the information from Point Beach personnel previously. Below is the information from the Point Beach notification: At 1520 CDT, Point Beach was notified by Manitowoc County Sherriff's Department (MCSD) and citizens of audible EP siren actuation in the city of Two Rivers and the town of Two Creeks, WI. System troubleshooting was in progress at the time of actuation. Alert and Notification System siren configuration was restored to normal at approximately 1630 CST, 09/09/10. All required ANS sirens were 'poll tested' and are fully functional. Further reviews indicated that sirens P-001 through P-013 (13 sirens) had each simultaneously received a 180 second activation. At this time the cause of the activation signal is unknown. All troubleshooting and testing are currently suspended; event investigation has commenced. The licensee notified the NRC Resident Inspector. |
