| Title | Non-Functional Emergency Sirens |
| Event Description | At 1200 CDT, on August 6th, 2015, during the monthly test of Emergency Plan sirens in Saint Charles Parish (county), all sirens failed to actuate when required. There are a total 73 sirens of which 37 sirens are in Saint Charles Parish, which covers approximately 49 percent of the total population within the Waterford 3 10-mile emergency planning zone. The siren vendor is currently investigating to repair the issue.
Waterford 3 still maintains 100 percent backup notification capabilities. The Saint John the Baptist Parish Sirens remain fully operational. The Saint Charles Parish Emergency Manager has been notified. This event did not result in any adverse impact to the health and safety of the public. The Waterford 3 and Saint Charles Parish Emergency Response Plans include back-up processes to provide warning to affected areas, if required, in the event of the loss of sirens. The NRC Resident Inspector has been notified. |
