| Title | Unusual Event Declared Due to Fire Alarm |
| Event Description | Cooper Nuclear Station control room received a fire alarm at 1529 CST indicating a fire in the service water pump room. The licensee responded by dispatching a fire brigade to the service water pump room to investigate. At 1541 CST, the licensee declared an unusual event in accordance with their emergency procedures due to their inability to confirm the validity of the fire alarm within a 10 minute period. The licensee exited the unusual event at 1559 CST after determining that the alarm was a false alarm caused by welding inside the service water pump room. The licensee issued a press release.
The licensee notified the NRC Resident Inspector, the Nebraska State Patrol, the Richardson County Sheriff's Office, Nemaha County Sheriff's Office, Missouri Highway Patrol, and the Atchison County 911 Center. |
