Title | Loss of Emergency Sirens |
Event Description | At approximately 0737 (CDT) on March 17, 2014, Waterford 3 was informed that four emergency sirens were inoperable. One other siren had previously been determined to be inoperable on March 12, 2014. Subsequent review during preparation of this notification has identified an additional eight inoperable sirens, which brings the total number of inoperable sirens to thirteen. There are a total of seventy-three sirens distributed among two parishes (counties). The loss of these thirteen sirens for more than one hour is considered a major loss of offsite response capability and is reported pursuant to 10 CFR 50.72(b)(3)(xiii).
The two affected parish Emergency Operations Centers were notified of the condition and it was confirmed that they will use the preplanned alternative method of Route Alerting for the affected areas until notified that repairs to the sirens have been completed. Waterford 3 is working to repair the sirens. There is no effect on the plant. This issue has been entered into the Waterford 3 Corrective Action Program and appropriate corrective actions will be developed. The NRC Resident Inspectors, local agencies, and the State of Louisiana were notified. |
