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. |

| LOSS OF COMMUNICATIONS WITH SAFETY PARAMETERS DISPLAY |
| |
| "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 |
| system. Because SPDS has been lost for longer than a short period of time, |
| Wolf Creek Nuclear Operating Corporation is making this notification |
| pursuant to 10 CFR50.72(b)(3)(xiii). There is no other loss of emergency |
| assessment capability concurrent with this on going loss of the SPDS. Plant |
| personnel entered the applicable Off Normal procedures and are taking local |
| readings of equipment normally monitored by the NPIS Computer." |
| |
| The Licensee notified the NRC Resident Inspector. |
| |
| *** UPDATE ON 3/23/03 AT 1645 CST FROM DAVE DEES TO ARLON COSTA *** |
| |
| "At 1320 CST 3/23/2003 the NPIS Computer was returned to service and |
| declared operable. The return of the NPIS Computer to an operable condition |
| restored the SPDS assessment capability function." |
| |
| The Licensee will notify the NRC Resident Inspector. |
