| Title | Offsite Notification Due to Emergency Siren Inadvertently Alarming |
| Event Description | At 2134 [CDT] on 7/16/2010 the NextEra Energy Duane Arnold control room was informed that an emergency siren in the Cedar Rapids area was alarming with an emergency message. This information came via a local news station stating that they had been receiving several phone calls regarding the siren message.
No emergency condition existed at NextEra Energy Duane Arnold and the siren appears to have malfunctioned and incidentally relayed the emergency message. NextEra Energy Duane Arnold has informed local media and the Linn County Emergency Director of the malfunctioning siren, and that no emergency condition exists at NextEra Energy Duane Arnold. The single siren (of the 144 total in the local siren system) was deactivated. The licensee notified the NRC Resident Inspector. |
