| Title | Loss of Tone Alert Radio System Tower |
| Event Description | At 1955 CST on 12/21/2015, Cooper Nuclear Station was notified by the National Weather Service that the Shubert radio transmission tower was not functioning. This affects the tone alert radios used to notify the public in the event of an emergency condition. This is considered to be a major loss of the public prompt notification system capability and is reportable under 10CFR50.72(b)(3)(xiii).
At 2017 CST, Nemaha, Richardson and Atchison county authorities within the 10 mile EPZ were notified of the condition and the effect on the tone alert radios and will utilize local route notification (backup notification method) making this condition reportable under 10CFR50.72(b)(2)(xi) for notification of other government agencies. Estimated return to service time is unknown. The cause of the failure is a loss of communication with the tower. The NRC Senior Resident Inspector has been notified of this condition. |
