| 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. |

| UNANALYZED CONDITION |
| |
| "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. |

| UNUSUAL EVENT |
| |
| 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. |
| |
| The licensee notified the NRC Resident Inspector and the surrounding |
| counties. |
| |

| |
| 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 licensee notified the NRC Resident Inspector and the surrounding |
| counties. |
| |
| * * * UPDATE AT 0008 ON 4/8/03 FROM MIKE KORSNICK TO ERIC THOMAS * * * |
| |
| 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. |
