Title | Inadvertent Siren Activation During Testing |
Event Description | At 1800 [CDT] on October 9, 2015 a polling test was initiated in Saint Johns Parish to test the circuitry of the installed sirens. During the polling test no sirens are expected to sound as it is only a circuitry test. Siren number SJ39 inadvertently sounded for 15 to 20 minutes, and no others. Saint Johns Parish notified the parish residents that the sounding of the siren was inadvertent via a Parish wide cable television channel and a press release. A contract vendor has disabled the siren and will troubleshoot and repair starting on October 12, 2015. All remaining sirens within Saint Johns Parish remain operational and capable of being activated when required. 0% of the population is affected by the loss of this siren due to siren overlap.
Time to repair and restore siren SJ39 to service is still being investigated. This event is reportable pursuant to 10CFR 50.72 (b)(2)(xi), News Release or Notification of Other Government Agency. The NRC Resident Inspector has been notified. |
