| The following is the text from a NC Department of Environment and Natural    |
| Resources News Release:                                                      |
|                                                                              |
| "A truck stolen about 4:30 this afternoon in Forsyth County was transporting |
| an instrument containing eight millicuries of Cesium-137, a radioactive      |
| material that is a potential health and safety risk if handled improperly or |
| broken open.                                                                 |
|                                                                              |
| "The truck is a white Ford F150. The instrument is a Troxler brand portable  |
| moisture density gauge model 4640B.  It is yellow and has a stainless steel  |
| handle with a radiation symbol protruding from a heavy base.  It is about    |
| 20-30 pounds and 24x12x14 inches. Its serial number is 1996. The gauge was   |
| in a yellow box 24x12 inches and marked as containing radioactive material.  |
| The box should be locked and chained to the truck.                           |
|                                                                              |
| "The gauge uses radioactive materials to test conditions of soil and asphalt |
| during construction.  Any health risk would occur only if a person were      |
| directly exposed to the sealed radioactive source inside the instrument.     |
|                                                                              |
| "Employees of Thompson-Arthur Division APAC-Carolina, Inc., a paving company |
| in Greensboro, left the truck unattended. The company's license with the     |
| state Division of Radiation Protection requires that the instrument not be   |
| left unsecured.                                                              |
|                                                                              |
| "Anyone who believes he or she has found the truck, box or gauge should stay |
| at least ten feet away and contact the local sheriffs office, police         |
| department or state highway patrol immediately."                             |
|                                                                              |

|                                                                              |

| The truck has been recovered by the Sheriff's department and will be picked  |
| up by the North Carolina Division of Radiation Protection until the licensee |
| can take possesstion.  The gauge in it's storage box was recovered           |
| separately.  The gauge and box appear undamaged and a survey will be         |
| conducted  when the North Carolina Division of Radiation Protection arrives  |
| on scene.  An additional report willl be sent later in the week.             |
|                                                                              |

| "Unit 1 was in Mode 5, day 28 of a refuel and inspection outage.  Unit 2 was |
| in Mode 1, 24% power for scheduled maintenance work requiring River Water    |
| Makeup to both units' cooling towers [to be] out of service."                |
|                                                                              |
| "At 2340 hours, Unit 1 began to experience low suction pressure to the 'C'   |
| Service Water pump, the only pump in service at the time.  Service Water     |
| takes suction from the Unit 1 Cooling Tower, and this condition resulted in  |
| low system discharge pressure and flow.  Service Water is the normal cooling |
| source for Units 1 [and] 2 Control Structure [Heating Ventilation and Air    |
| Conditioning (HVAC)].  The 'A' Control Structure chiller tripped, and the    |
| 'B' Control Structure chiller failed to start due to the low flow condition  |
| on service water.  With both chillers tripped and unavailable for CREOAS and |
| Control Room Floor Cooling, [the Limiting Condition for Operation (LCO) for  |
| Technical Specification] 3.0.3 was entered on Unit 2.  This represented a    |
| Loss of Safety Function for Accident Mitigation and requires an [8-hour] ENS |
| notification in accordance with 10CFR50.72(b)(3)(v)."                        |

| "The Control Structure chillers were realigned to Emergency Service Water    |
| (ESW), its backup emergency cooling source.  The 'A' Chiller failed to       |
| re-start, but the 'B' Chiller was successfully placed in service.  LCO 3.0.3 |
| was able to be exited on Unit 2 at 0012 hours on 3/30/02."                   |

| DIESEL GENERATORS DECLARED INOPERABLE FOR SHORT TIME PERIOD                  |

| "During performance of 24 month Division 1 Diesel Generator LOCA/LOOP        |
| surveillance testing, two pump start timers failed to meet the required      |
| acceptance criteria. The A RHR Pump timer actuated at 3.72 seconds           |
| (criteria: 2.7 sec. to 3.6 sec) and the C ESW Pump timer actuated at 39.24   |
| seconds (criteria: 39.6 sec. to 48.4 sec). With failure of the timers proper |
| loading on the Diesel Generators is not assured, and they ['A' and 'C'] were |
| declared inoperable until the associated pump control breakers were opened.  |
| The Susquehanna safety analysis requires three operable Diesel Generators to |
| safely shutdown the plant. Therefore with only two operable Diesel           |
| Generators, the condition requires an 8 hr ENS notification in accordance    |
| with 10CFR50.72(b)(3)(v) and (vi)."                                          |

| With Unit 1 shutdown the 'A' RHR pump is not needed, but the 'C' ESW pump    |
| does need to be operable resulting in part of the 8 hour report.             |
