| "On June 6, 2002 at 4:30 p.m. the Arkansas Department of Health was notified |
| by Albemarle Corporation in Magnolia, Arkansas that a fixed density gauge    |
| source had been damaged. Albemarle has Arkansas Radioactive Material License |
| ARK-717-BP-11-99. The device is a Ronan Engineering Company Model SA-15      |
| containing two 5 millicuries sources of Cesium-137. The device was locked    |
| out on June 3, 2002. On June 6, 2002 while the source housing was being      |
| adjusted it was noted that the source rod was in a different configuration.  |
| Radiation surveys were performed and it appeared that one of the 5           |
| millicuries sources was not attached to the source rod. The immediate area   |
| was secured and access has been restricted. Albemarle has contacted a        |
| consultant to assist in retrieval and packaging of the source for return to  |
| the manufacturer.                                                            |

| "The Department has sent two inspectors to the facility to investigate and   |
| assess the Incident on June 7, 2002. It appears that there may have been     |
| personnel radiation exposure due to this incident. This incident is under    |
| investigation."                                                              |

| With the source in the stored position, an employee of Isomedix Operations,  |

| Four detectors each containing 15 millicuries of nickel-63 were lost at Fort |
| Hood, Texas.  On 05/29/02, Fort Hood received the report that the detectors  |
| might be missing.  Apparently, they were misplaced during preparations to    |
| send them to a maintenance shop for wipe testing.  The detectors were        |
| verified to be missing on 06/05/02, and Fort Hood notified Aberdeen on       |
| 06/11/02.                                                                    |

| The licensee reported an explosion and subsequent fire that occurred in the  |
| station's 345-kV electrical switchyard.  Neither reactor plant was directly  |
| affected by the event and both remained at power.  The licensee declared an  |
| Alert at 1405 based on the switchyard fire potentially affecting safety      |
| related equipment such as the reserve power to safety-related electrical     |
| buses. Several switchyard breakers tripped open at 1345 placing the units in |
| TS 3.0.5.  One injury was reported.  Planned maintenance was in progress in  |
| the switchyard at the time of the event.                                     |
|                                                                              |

| At 2157, the licensee declared the Unit 2 east essential service water pump  |
| operable, and Unit 2 exited Technical Specification 3.0.5 at that time.      |
| Unit 1 exited Technical Specification 3.0.5 approximately 5 minutes earlier. |
| At 2347, both units exited Technical Specification 3.8.1.1 when the licensee |
| restored transformer 4 to serve the Unit 2 reserve auxiliary transformers    |
| and isolated it from Unit 1 (which is being fed by transformer 5).  As a     |
| result, the licensee terminated the Alert and exited the Emergency Plan at   |

| 24 HOUR BULLETIN 91-01 REPORT AT PADUCAH                                     |
|                                                                              |
| "At 0820 CDT, on 6-12-02 the Plant Shift Superintendent was notified of an   |
| NCS violation that had occurred in the C-335 process building. The           |
| calibrated AQ-NCS pressure chart recorders for C and E surge drum banks had  |
| previously failed. As a result of this failure the shiftly pressure checks   |
| were performed using non AQ-NCS pressure instrumentation and therefore were  |
| not valid. The purpose of the pressure check is to identify if wet air       |
| inleakage has begun on surge drum bank. An alternate AQ-NCS pressure         |
| instrument has now been connected to the system and follow-up pressure       |
| readings have been taken. The pressure readings indicate there has been no   |
| wet air inleakage. The required checks have been restarted. Double           |
| contingency has been restored.                                               |
|                                                                              |
| "This is an event is which a violation of the double contingency principle   |
| occurred and where double contingency was re-established within four hours   |
| of the initial observation of the event. The NRC Resident Inspector has been |
| notified of this event.                                                      |
|                                                                              |
| "SAFETY SIGNIFICANCE OF EVENTS:  Although pressure readings were taken on a  |
| shiftly basis, these readings were not valid because the instrumentation     |
| used was not AQ-NCS. Therefore double contingency was not maintained.        |
|                                                                              |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED: In order for a criticality to be   |
| possible a surge drum would have to contain a critical mass of UO2F2 in an   |
| unfavorable geometry, wet air inleakage would need to occur, and the uranium |
| mass would have to be sufficiently moderated.                                |
|                                                                              |
| "CONTROLLED PARAMETERS: Double contingency is maintained by implementing two |
| controls on moderation.                                                      |
|                                                                              |
| "NUCLEAR CRITICALITY Y SAFETY CONTROL(S): The first leg of double            |
| contingency is based on maintaining the integrity of the surge drum system   |
| against wet air inleakage. This integrity is assured by an SRI for the       |
| unlikely breach of the surge drum system.  Structural integrity of the drum  |
| is intact, therefore this SRI is maintained. The second leg of double        |
| contingency is based on the performance of the shiftly pressure checks of an |
| AQ-NCS instrument as an indication of wet air inleakage. The required checks |
| were performed using an uncalibrated instrument. Since an uncalibrated       |
| instrument was used, the shiftly checks were invalid resulting in a loss of  |
| this control. Since there are two controls on one parameter, double          |
| contingency was not maintained.                                              |
|                                                                              |
| "CORRECTIVE ACTIONS: 1) Isolate the affected surge drum banks until the      |
| original pressure indication equipment is repaired. The drums were isolated  |
| at 1025 CDT on 6-12-02.  2) Connect AQ-NCS pressure indication equipment and |
| monitor in accordance with procedure CP4-CO-CN6069 until the original        |
| pressure indication equipment is repaired. An alternate AQ-NCS approved      |
| instrument was connected, and readings were taken at 1040 CDT on 6-12-02."   |

| OFFSITE NOTIFICATION REGARDING A RELEASE OF RAW SEWAGE TO THE
CHESAPEAKE     |
| BAY                                                                          |
|                                                                              |
| The licensee reported that an air leak caused a level detector in a large    |
| inlet pumping well to fail low.  As a result, the sump pumps stopped and did |
| not restart when actual level reached the high level setpoint.  The inlet    |
| sump of the onsite sewage treatment plant subsequently overflowed, and raw   |
| sewage was released to the Chesapeake Bay.                                   |
|                                                                              |
| The licensee estimates that the quantity of raw sewage involved was between  |
| 2,500 and 7,200 gallons.  Additional calculations are currently being        |
| performed.  The level detector malfunctioned has since been repaired.        |
|                                                                              |
| The licensee notified the NRC resident inspector and local county and plans  |
| to notify the Maryland Department of Environmental Protection.               |
