This recent report from the Seabrook Nuclear Plant in New Hampshire brightened my day, but may keep me awake giggling all night. There may be a song in this:

                                    EVENT TEXT

| UNUSUAL EVENT DECLARED DUE TO POTENTIAL INTRUDER INSIDE THE PA               
|
| The licensee provided the following information during their initial call:   |

"We declared a UE (Unusual Event) [at 2053 EST] based on 18A.Security declared code Red. We have an intruder in the PA (Protected Area).We have no indications of off normal plant conditions and we have no specific threat |indicated."

The licensee initially reported that their CAS (Central Alarm Station) received an alarm from the security fence around the PA. Some security force members reported seeing some sort of object come over the fence simultaneous with the alarm. Site security immediately responded to the situation, along with the Seabrook Emergency Response
Team (SERT), and the FBI.
| Region I developed a timeline for this event, contact the HOO for details.   |

An ongoing conference bridge was established with NSIR management (Holonich, Zimmerman), headquarters and regional IAT members (Warren, Smith, Whitney), Region I management (Miller, Wiggins, Blough, McDermott, Frechette), the NRC Resident Inspector (Dentel), and the FBI.                                    |
|
The NRC went to Monitoring Mode for this event at 2230 EST on 3/22/03.   
*** UPDATE AT 0720 EST ON 3/22/03 BY ERIC THOMAS ***

The FBI is conducting interviews with 4 site security personnel. The FBI has completed two of four interviews with security personnel. One, who was in the CAS, says he saw a square-looking object cross his screen that monitors the protected area boundary. The second interviewee was patrolling outside the protected area in his vehicle and saw a large bird (probably a wild turkey) with approximately a four-foot wing span fly across the road in front of him. This coincides with the location and time at which the CAS operator saw the image on his screen.                                       

The licensee is planning to perform walkdowns of all vital systems, and the SERT teams are performing additional sweeps of the protected area this morning. Additionally, licensee personnel in the Seabrook TSC are updating Region I NRC personnel on the situation every 30 minutes.                   |

*** UPDATE AT 1030 EST ON 3/22/03 BY ERIC THOMAS ***                        

Security personnel completed second sweep of the protected area at 0955 with negative results. Interviews with 4 security personnel by the FBI revealed the following likely scenario:                                              |
Approximately 2030 on 3/21/03 - PA fence alarm coincides with CAS security officer seeing a dark mass coming over the fence on his monitor CAS personnel then saw this featureless mass disappear behind a building inside the PA.

Approximately 2100 - CAS security officer notices dark mass on the monitor fly from a building downward over the PA security fence. Shortly thereafter, a security officer on patrol outside the PA sees a wild turkey with approx. 4-foot wing span fly across the road about 20 feet in front of his vehicle.

Searches of the fence line in the area of the intrusion revealed no footprints or damage to the fence. Conclusion by site operations and security personnel, as well as FBI, is that the fence alarm was caused by intrusion of some sort of wild animal, possibly a turkey, and that there was no human intrusion onto the site.                                          

*** UPDATE AT 1102 EST ON 3/22/03 BY LICENSEE TO ERIC THOMAS ***            

The licensee terminated the Unusual Event at 1052 EST on 3/22/03.         

*** UPDATE AT 1235 EST ON 3/22/03 BY ERIC THOMAS ***                        

The NRC exited Monitoring Mode at 1205 EST.                                 

A Commissioners' Assistants' brief was held at 1230 EST. See HOO log for additional details.                                                         

Have a nice day and a peaceful night,
