| ATTEMPTED THEFT OF A TROXLER GAUGE                                           |

|                                                                              |

| The Texas Department of Health reported the attempted theft of a Troxler     |

| Model 3430, (serial # unknown), on the night of 3/31/03 from a secure        |

| storage trailer at a Texas Department of Transportation construction site in |

| Abilene, TX.  Site personnel discovered the gauge in an open case on the     |

| floor of a construction trailer with its lock cut.  The trailer and its      |

| storage closet had been broken into.  The sealed source contains 8           |

| millicuries of Cs-137 and 40 millicuries of Am-241/Be.  Gauge is currently   |

| secured in a different area awaiting results of leak and serviceability      |

| tests.  An investigation is in process to determine whether other items were |

| stolen, or whether this gauge was the only target of the attempted theft.    |

|                                                                              |

| This event is technically not reportable, but was entered as an attempted    |

| theft due to three other similar incidents that did result in stolen gauges  |

| in the Dallas-Fort Worth area under similar circumstances.  The Texas        |

| Department of Transportation notified all other licensee's possessing        |

| portable nuclear gauges in the Abiline and Dallas-Fort Worth regions, along  |

| with local police and the Dallas FBI office.                                 |

| "During the System Health Readiness Review at Davis-Besse Nuclear Power      |

| Plant, a potential issue was discovered concerning operability of the HPI    |

| Pumps. When the HPI Pumps are taking suction from the emergency sump (i.e.,  |

| under post LOCA condition after the initial HPI injection has occurred and   |

| BWST has been depleted), it could receive particle size that could damage or |

| render the HPI pumps inoperable due to sump debris. A review of pump design  |

| and rotor dynamic analysis have determined that [the] pumps are unsuitable   |

| to take suction from a source that contains debris in the water, such as the |

| post LOCA debris (i.e., fibrous material from insulation) in the containment |

| emergency sump.                                                              |

|                                                                              |

| "The above issue is documented in Condition Report 03-01738 and is currently |

| being further investigated. Davis-Besse has determined that the above        |

| condition will be reportable under 10 CFR 50.73(a)(b)(v), Event or Condition |

| that could have prevented fulfillment of a safety function, and 10 CFR       |

| 50.73(a)(2)(ii), Degraded or Unanalyzed Condition. Although this condition   |

| was discovered during plant shutdown where HPI pumps are not required to be  |

| operable per TS 3.5.2, a subsequent review of immediate notification         |

| requirements found this condition may require an 8 hour notification via 10  |

| CFR 50.72(b)(3)(ii), i.e., that is to report a historical condition where    |

| [a] degraded/unanalyzed condition existed within 3 years. The Statements of  |

| Consideration for this reporting criterion implies such conditions if it     |

| existed within 3 years should be reported via 10 CFR 50.72(b)(3)(ii)."       |

|                                                                              |

| The licensee notified the NRC Resident Inspector.                            |

| At 2201, a fire started in the pressurizer doghouse.  Welding operations     |

| were ongoing in the upper part of the space, and a slag catchment device     |

| lower in the space caught fire.  The fire brigade responded to the scene.    |

| At 2219, the licensee declared an Unusual Event because of an ongoing fire   |

| in the vital area for greater than 15 minutes.  At 2234, the fire was put    |

| out by pouring water down onto the fire from above, and a reflash watch was  |

| set.  There was no damage noted to plant equipment, and no injuries to       |

| personnel.                                                                   |

| At 2300, the licensee secured from the Unusual Event.  There was no damage   |

| noted to plant components, and scaffolding will be erected to conduct        |

| further inspections.                                                         |

| The cause of the fire was slag from welding operations that fell through     |

| some fire blankets and ignited the herculite underneath.  A fire brigade     |

| member will be sent back into the space this morning to conduct further      |

| damage assessment.                                                           |
