| Title | Inadvertent Activation of All Emergency Sirens |
| Event Description | At 1301 [CDT] on October 4, 2012, during the restoration of a single Farmer City owned siren, DeWitt County Emergency Dispatch Center inadvertently activated all of Clinton Power Station's emergency sirens instead of the Farmer City owned siren. A siren in the Farmer City area had fallen off a pole, and following repairs, instead of testing the individual siren, the Dispatch Center inadvertently actuated all 40 Clinton Power Station sirens. The sirens were actuated for approximately 1 minute and 14 seconds. The Clinton Power Station siren system covers parts of four surrounding counties (DeWitt, Piatt, McLean, and Macon).
A spurious actuation of one or more emergency response sirens is reportable under 10CFR50.72(b)(2)(xi) addressing a notification of a government agency related to the health and safety of the public. The NRC Resident Inspector has been notified. All of the affected county Emergency Management Agencies have been notified. The DeWitt County Sheriff has notified various media outlets. |
