| FIRE PROTECTION REQUIREMENTS NOT MET |
| |
| It has been discovered that all necessary compensatory actions for |
| inoperable fire barriers are not included in the stations operating |
| procedures for conditions when the swing 125 VDC and 250 VDC battery |
| chargers are in service supplying the 'B' DC Electrical subsystem. The |
| required degree of separation per 10CFR50 Appendix R does not exist between |
| divisions when either swing charger is connected to the 'B' DC Electrical |
| subsystem. Use of the swing chargers is not a normal lineup but has occurred |
| during the past three years. The uncompensated lack of an adequate fire |
| barrier between divisions of safe shutdown equipment is considered an |
| unanalyzed condition that significantly degrades plant safety. |
| |
| The licensee notified the NRC resident inspector. |

| TECH SPEC REQUIRED SHUTDOWN |
| |
| Initiation of a unit shutdown began at 1700 May 9, 2001, as required by T.S. |
| 3.7.B because Unit 2 Diesel Generators D5 and D6 were declared inoperable at |
| 1506. They were declared inoperable because it was determined that they may |
| not be capable of long-term operation as assumed in the plant accident |
| analyses. This determination is based on the discovery that the diesel fuel |
| and lubricating fluids in the engines may be incompatible and may damage the |
| engines based on a re-review of industry operating experience. |
| |
| The plant will go to Mode 5 and remain their until corrective actions are |
| complete. |
| |
| The licensee notified the NRC resident inspector. |

| MANUAL TURBINE TRIP - AUTOMATIC REACTOR TRIP |
| |
| Initiated manual turbine trip due to condenser vacuum differential pressure |
| which resulted in an automatic reactor trip. Reactor power prior to the |
| trip was 12.5%. The cause of the high condenser vacuum differential |
| pressure is undetermined at this time. |
| |
| All control rods fully inserted, reactor coolant pumps are running. The |
| steam generators are being fed with auxiliary feed. Decay heat is being |
| removed by dumping steam with the turbine bypass atmospheric dumps. There |
| are no known S/G tube leaks. |
| |
| The licensee notified the NRC resident inspector. |
