| LOSS OF POWER TO THE TECHNICAL SUPPORT CENTER (TSC) |
| |
| 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. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * Update at 1150 on 12/22/00 by Hubbard received by Weaver * * * |
| |
| The diesel generator is now supplying the TSC with electrical power (as of |
| 1041 CST). Investigation continues into why breaker 13-40 tripped. |
| |
| Notified the R4DO(Jones). |

| INOPERABLE |
| |
| HPCI was declared inoperable after failing testing. During the performance |
| of 2-SI-3.5.1.7 HPCI MAIN AND BOOSTER PUMP SET DEVELOPED HEAD AND FLOW RATE |
| TEST AT RATED REACTOR PRESSURE, the HPCI system could not be verified to be |
| vented. |
| |
| The probable reason for not being able to make this verification is due to a |
| faulty flow gauge in the HPCI piping system. |
| |
| The NRC Resident Inspector will be notified. |

| "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." |
| |
| The licensee notified the NRC Resident Inspector. The R2DO (Mike Ernstses) |
| was notified. |

| 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. |
