| Breaker 13-40 tripped with the ground flag dropped.  This breaker supplies   |
| primary power to the TSC.  There is a backup diesel generator available to   |
| supply power to the TSC but will not be energized until it is determined     |
| that there is no ground at the TSC.  Once the TSC D/G is energized the       |
| facility will once again be available.                                       |
|                                                                              |

| TEST AT RATED REACTOR PRESSURE, the HPCI system could not be verified to be  |
| vented.                                                                      |

| "The 4 hour report made in accordance with 10CFR50.72.b.2.iii at 1630 on     |
| 12/22/2000 is being retracted for the following reasons:  During the         |
| performance of 2-SR-3.5.1.7 HPCI MAIN AND BOOSTER PUMP SET DEVELOPED HEAD    |
| AND FLOW RATE TEST AT RATED REACTOR PRESSURE, there were indications of flow |
| through the vent line during initial Surveillance testing however; the test  |
| methodology used in the Surveillance could not verify that flow. We revised  |
| the Surveillance methodology to prescribe an alternate process of            |
| determining flow. The Surveillance test was reperformed satisfactorily and   |
| verified indications of flow that was observed in the previous performance   |
| of the Surveillance test. Thus this proved operability of HPCI during        |
| previous performance of Surveillance test."                                  |

| FACILITY HAS PROBLEMS WITH FREEZING STANDPIPES THAT SUPPLY WATER TO THEIR    |
| HIGH PRESSURE FIRE WATER SYSTEMS.                                            |
|                                                                              |
| During a discussion between the Paducah and Portsmouth Plant Shift           |
| Superintendents (PSS), the Portsmouth PSS stated that their facility was     |
| having a problem with the standpipes freezing that supply water to their     |
| High Pressure Fire Water (HPFW) systems.  Following this discussion, the     |
| Paducah PSS instructed all building managers containing HPFW systems to      |
| check the temperatures of the standpipes.  Following this temperature        |
| survey, two systems in the C-337 building were discovered to have abnormally |
| low temperatures.  In order to verify operability, Fire Services personnel   |
| performed flow tests on these two systems.  During this testing, it was      |
| discovered that the standpipe for HPFW system D-2 was frozen, and the system |
| could not perform its specified safety function.  The High Pressure Fire     |
| Water System is required to be operable according to TSR 2.4.4.5. HPFW       |
| system D-2 was declared inoperable at 0615 on 12-23-00, and a fire patrol    |
| was initiated as required by the TSR.  During follow up investigation, it    |
| was discovered that six of the eight exhaust fans and a section of           |
| recirculating louvers that supply heat to this area were not functioning.    |
|                                                                              |

| The NRC Resident Inspector has been notified of this event.                  |
