| EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE                              |
|                                                                              |
| At 1347 on 1/4/2002, the "A" emergency diesel generator (EDG) was declared   |
| inoperable due to tube degradation identified in the lube oil, intercooler   |
| and jacket water heat exchangers.  Technical Specification 3.8.1 was         |
| entered, the affected heat exchanger tubes were plugged and the "A" EDG was  |
| restored to operable status at 1134 on 1/5/2002.                             |
|                                                                              |
| At 1301 on 1/5/2002, the "B" EDG was taken out of service to perform         |
| inspections of its lube oil, intercooler, and jacket water heat exchangers.  |
| Inspection of the heat exchanger tubes and analysis of the inspection data   |
| found similar results, subsequently resulting in the need to plug heat       |
| exchanger tubes to restore the "B" EDG to operable status.                   |
|                                                                              |
| Based upon the similarity and extent of the tube degradation in both the "A" |
| and "B" EDG heat exchangers, prior to implanting the tube plugging           |
| corrective action, the possibility exists that the degradation of the EDG    |
| heat exchangers' tubes could have prevented the fulfillment of the safety    |
| function of the onsite standby class 1E power source following a design      |
| basis earthquake.                                                            |

| Subsequent evaluation of the heat exchangers by the licensee determined that |
| the degradation was not severe enough to interfere with the proper operation |
| of the EDGs.  The licensee is retracting the event notification, as the EDGs |
| were operational and fully available.                                        |

| "On February 26, 2002, following shutdown for a scheduled refueling outage,  |
| the Davis-Besse Nuclear Power Station performed a qualified visual           |
| examination of the Reactor Vessel head per NRC Bulletin 2001-01.  This       |
| examination revealed evidence of boric acid build up around Control Rod      |
| Drive Mechanism (CRDM) nozzles but was inconclusive due to the previous      |
| known boric acid deposits.  At approximately 1330 hours on February 27,      |
| 2002, Ultrasonic Testing (UT) data identified axial through weld indications |
| on one CRDM.  Engineering evaluation of this data confirmed Reactor Coolant  |
| System pressure boundary leakage exists.  Technical Specification 3.4.6.2.a  |
| states that Reactor Coolant System leakage shall be limited to no pressure   |
| boundary leakage.  As a result this is being reported as a non-emergency,    |
| 8-hour report in accordance with 10CFR50.72(b)(3)(ii)(a), a condition that   |
| resulted in the nuclear power plant, including its principal safety barriers |
| being seriously degraded."                                                   |
|                                                                              |
| The licensee stated that UT inspections are continuing on other nozzles.     |
|                                                                              |
| The licensee plans to notify the NRC resident inspector.                     |
|                                                                              |

| "All inspections have been completed at this time. UT data for CRDM nozzles  |
| 1 and 2 (locations H-8 and G-7, respectively) has been evaluated to exhibit  |
| axial indications that represent pressure boundary leakage. This completes   |
| evaluation of the extent of the condition for the report communicated on     |
| February 27."                                                                |

| The licensee notified the NRC Resident Inspector.  The R3DO (John Madera),   |
| NRR EO (David Matthews), and IRO (Tim McGinty) have been informed.           |
