| event text = At approximately 1345 CST on 7/16/04, Cooper Nuclear Station was informed by Emergency Preparedness officials of Nemaha County that the radio transmission tower that provides signals to activate tone alert radios within the 10-mile Emergency Planning Zone (EPZ) was not functioning. Tone alert radio is relied on by approximately 650 households in the EPZ, who are not in audible range of sirens for notification of an emergency at CNS. Based on a total EPZ population currently estimated at 4600 persons (who are alerted principally by sirens and the tone alert radio), this is considered to be a major loss of the Public Prompt Notification system capability, and is reportable under 10CFR50.72(b)(3)(xiii). | | event text = At approximately 1345 CST on 7/16/04, Cooper Nuclear Station was informed by Emergency Preparedness officials of Nemaha County that the radio transmission tower that provides signals to activate tone alert radios within the 10-mile Emergency Planning Zone (EPZ) was not functioning.

Investigations are ongoing. The cause appears to be an inadvertently severed telecommunications cable to the tower. There does not appear to be any evidence of sabotage. It is expected that repairs will be completed by 1800 CST on 7/16/04. During the interim, compensatory measures have been verified to be in place via state and local emergency planning officials for backup route alerting for personnel within the 10-mile EPZ. | Investigations are ongoing.
