| 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.                                            |

|                                                                              |

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

|                                                                              |

| "On 3/21/2003 at 22:07, the Wolf Creek Generating Station experienced an     |

| unexpected loss of the Nuclear Plant Information System (NPIS) Computer.     |

| This computer supplies data for the Safety Parameter Display System (SPDS).  |

| Trouble shooting efforts have been unsuccessful, thus far, in restoring the  |

| pursuant to 10 CFR50.72(b)(3)(xiii).  There is no other loss of emergency    |
