| TWO DIESEL GENERATORS INOPERABLE DURING TESTING                              |
|                                                                              |
| During performance of the monthly testing of the #3 Emergency Diesel         |
| Generator (EDG), the voltage regulator (control power) would not adjust      |
| incoming voltage lower than 120 volts.  The diesel was declared inoperable   |
| pending further troubleshooting of the voltage regulator.                    |
|                                                                              |
| As required by Surry technical specifications, the #1 and #2 EDGs were       |
| scheduled for operability testing on a daily basis.  The #1 EDG was          |
| inoperable from 2024 hours to 2203 hours for required testing which rendered |
| inoperable both EDGs for Unit 1.  The #1 EDG was available at all times      |
| during testing; however, it would have required operator action to load on   |
| the bus.                                                                     |

| This report is being made pursuant 10CFR50.72(b)(2)(iii)(A) and (D) for a    |
| condition that alone could have prevented the fulfillment of safety          |
| structures or systems needed to shut down the reactor and maintain it in a   |
| safe condition and mitigate the consequences of an accident.                 |
|                                                                              |

| "Based on further review of this event and the guidance provided in          |
| NUREG-1022, it was determined that this event was not reportable since the   |

| "McGuire Nuclear Station has determined that provisions of their fire        |

| [Unit  1] and C. (7) [Unit 2] of the Facility Operating Licenses.            |
|                                                                              |
| "Selected Licensee Commitment 16.9-5 requires that all fire rated assemblies |

| Redundant analyzed post fire safe shutdown equipment or, (3) The Control     |
| Complex (Control Rooms, and Battery Rooms) from the remainder of the plant   |
| or, (4) Containment from non-containment areas shall be operable. Contrary   |
| to this, six penetrations were discovered during a configuration inspection  |
| to not satisfy the commitment for separation of safety from non-safety       |
| related areas. Specifically, two penetrations were discovered with no seal   |
| installed, and four penetrations found with an improper installation of the  |
| seal. Remedial actions required by Selected Licensee Commitment 16.9-5 have  |
| been implemented (fire watches). This condition did not impair the ability   |
| of the Standby Shutdown System to perform the function of mitigating all 10  |
| CFR 50 Appendix R fire event. Therefore McGuire did not operate outside the  |

| "In accordance with 10 CFR 50.72 (b)(2)(iii), PG&E is making a 4-hour        |
| non-emergency notification report of a condition that alone could have       |
| prevented the fulfillment of a safety function needed to mitigate the        |
| consequences of an accident.  On October 26, 1999, at 0015 PDT, PG&E         |
| discovered a void in the common suction line for the emergency core cooling  |
| (ECCS) pumps.  PG&E immediately entered Technical Specification 3.0.3,       |
| vented the void, and exited TS 3.0.3. on October 26, 1999, at 0040 PDT.      |
| PG&E was in the process of writing a 30 day report in accordance with 10 CFR |
| 50.73(a)(2)(i)(B).                                                           |

| "On November 16, 1999, at 1045 PST, during a telecommunication between PG&E  |
| and the NRC, the NRC stated that the condition should have been reported as  |
| a four-hour non-emergency report.  PG&E has previously demonstrated that the |
| void condition would not have prevented the safety function of ECCS to       |
| recirculate reactor coolant after a loss of coolant accident.  However, PG&E |
| also identified that either both centrifugal charging pumps (CCP) or both    |
| safety injection pumps (SIP) could have become inoperable due to air         |
| binding. The NRC stated that if either SI or the charging system were        |
| inoperable, then the safety function of a safety system was not met and the  |
| event would be reportable under 10 CFR 50.72.  PG&E concluded that even      |
| though the overall safety function of post LOCA recirculation was            |
| maintained, the analysis showed that either the CCPs or SIPs (both are       |
| subsystems) were inoperable and therefore reportable under 10 CFR 50.72      |
| (b)(2)(iii)."                                                                |

| "At 1830 CST a Turbine Intercept Valve Fast Closure alarm and an EHC         |
| Malfunction Alarm occurred.  Intercept Valves 4, 5, and 6 were observed to   |
| be closed.  Intercept valves 1, 2, and 3  were 50% open.  #1 main turbine    |
| control valve was oscillating as was 'A' Low Pressure Turbine inlet          |
| pressure.  Multiple feedwater heaters were lost during the transient.  A     |
| manual reactor scram was inserted at 1834 CST.  All rods fully inserted on   |
| the scram. Reactor water level reached  -13" following the scram. There were |
| no PCIS, ECCS, or ESF actuations other than the inserted manual scram. The   |
| cause of the EHC alarms and valve response is unknown at this time. The      |
| forced outage plan will be implemented."                                     |

| During the transient a high pressure spike was observed, however, no safety  |
| relief valves lifted.  Decay heat is being removed via the bypass valves to  |
| the main condenser.  The licensee informed the NRC resident inspector.       |
