| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified  |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems  |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question.  Subsequently, these         |
| sprinkler systems were declared inoperable, and TSR-required actions         |
| establishing roving fire patrols were initiated.  This deficiency was        |
| detected during scheduled system inspections conducted by Fire Protection    |
| personnel.  Currently, functionality of the sprinkler heads has not been     |
| fully evaluated by Fire Protection personnel, and the remaining cascade      |
| buildings are currently being inspected, and if necessary, this report will  |
| be updated to identify any additional areas.  It has been determined that    |
| this event is reportable under 10CFR76.120(c)(2) as an event in which        |
| equipment is disabled or fails to function as designed."                     |

| HIGH PRESSURE CORE SPRAY (HPCS) DECLARED INOPERABLE DUE TO ITS MINIMUM FLOW  |
| VALVE FAILING TO FULLY OPEN.                                                 |
|                                                                              |
| Clinton Power Station is presently performing a planned Division-3 (HPCS     |
| diesel) outage.  The plant has been in a limited condition for operation     |
| allowed by technical specifications for this outage since 0230 CDT on        |
| 10/26/99.  At 1920 CDT on 10/26/99 during performance of a high pressure     |
| spray system surveillance the HPCS minimum flow valve (1E22-F012) failed to  |
| operate properly.  During an open stroke of the minimum flow valve, power    |
| was lost due to a breaker trip, and the valve failed to fully open.  This    |
| valve provides a minimum amount of flow through the system to ensure that    |
| the pump does not overheat.  The plant's technical specification provides    |
| allowances for this condition, but 10CFR50.72(b)(2)(iii)(D) requires that a  |
| component failure that could have prevented an independent safety system     |
| from performing its function be reported.  This system may have failed to    |
| perform its safety function due to the failure of this valve; thus, this     |
| report is being made.  The licensee entered Technical Specification 3.5.1    |
| (14-day limiting condition of operation).  The reactor core isolation        |
| cooling system and all emergency core cooling systems are fully operable if  |
| needed.  The electrical grid is stable, and the Division 1 and 2 emergency   |
| diesel generators are fully operable.                                        |
|                                                                              |
| The NRC resident inspector was notified of this event by the licensee.       |
|                                                                              |

| MACKINNON * * *                                                              |
|                                                                              |
| Further evaluation of this condition by engineering has determined that this |
| condition is not reportable.  If HPCS was called to function in accordance   |
| with its design safety function while the 1E22-F012 minimum flow valve was   |
| left open, HPCS injection flow would have been reduced.  The engineering     |
| evaluation shows that the reduction of HPCS system flow caused by the        |
| minimum flow valve open would not compromise the safety function of HPCS     |
| system.  That is, even with the minimum flow valve wide open, HPCS could     |
| still perform its safety function and designed RCIC backup function.         |
| Therefore, there is no reportability under 10CFR50.72(b)(2)(iii)(D), and     |
| this report is being retracted.                                              |
|                                                                              |
| The NRC resident inspector was notified of this event retraction by the      |
| licensee.  The R3DO (Gardner) was notified by the NRC operations officer.    |

| "This notification retracts a notification made on 11/17/99 due to RCIC flow |

| "The apparent down scale condition of the RCIC flow indicator was the result |

| While rolling the turbine during post-maintenance testing of RCIC system for |
| Unit 2, the turbine tripped on high exhaust pressure.  The turbine trip is   |
| caused by either one of two instruments sensing a high turbine exhaust       |
| pressure (nominally 45 psi).  Turbine exhaust pressure was not noted to be   |
| abnormally high on the control room instrumentation during this evolution.   |
| The licensee entered Technical Specification 3.7, which requires that the    |
| licensee return the RCIC system to service within 14 days or to shut down    |
| the unit.  All emergency core cooling systems are fully operable.            |
| Maintenance and engineering personnel are investigating this problem with    |
| initial focus on the pressure sensing instrumentation.                       |

| During a walkdown of the control room, the licensee discovered that an       |
| Agastat relay for the Train 'A' standby liquid control system was not        |
| seismically restrained.  The seismic restraint for the relay (C41-K002A) was |
| unclipped.  Train 'A' of the standby liquid control system was declared      |
| inoperable, and Technical Specification 3.1.7 (one train of the standby      |
| liquid control system inoperable for more than 7 days or shut down) was      |
| entered.  The seismic restraint was reclipped, and Train 'A' of the standby  |
| liquid control system was declared operable at 1223 EST.                     |
|                                                                              |
| A search of the licensee's records revealed that no work activity had been   |
| performed on the relay since initial startup.  The licensee has assumed that |
| the Agastat relay has been non-seismically qualified since initial startup   |
| which requires a 24-hour notification to the NRC per Operating License       |
| 2.C.2, item b (24-hour call to the NRC when the technical specification time |
| limit is exceeded).                                                          |

| were using a proflame torch to cut a contaminated moisture separator in      |
| Building E, Safeshop B.  The employees noticed smoke coming out of the dust  |
| collection system.  This system has three sets of filters:  prefilters,      |
| canisters, and HEPA.  The fire alarm was activated, and the employees were   |
| evacuated from the plant.  Firefighters responded within 15 minutes.  Two    |
| firefighters and two GTS employees went into the area.  Dry chemicals were   |
| used to try to extinguish the fire but were unsuccessful.  Water was used to |
| extinguish the fire.  A garden hose was used instead of the standard fire    |
| hose to minimize the amount of water that could be possibly become           |

| LOSS OF 27 OF 31 OFFSITE EMERGENCY SIRENS                                    |
|                                                                              |
| At 0414 on 11/25/99, the Salem County Emergency Call Board notified licensee |
| maintenance personnel that two offsite sirens were inoperable.  At 0710,     |
| licensee maintenance personnel received a second call from the Salem County  |
| Emergency Call Board stating that 27 of 31 offsite sirens were inoperable    |
| due to an unplanned power outage.  It is uncertain as to when the additional |
| sirens became inoperable after the initial call was received at 0414.  Power |
| was restored to the offsite sirens at 0720, and all sirens are currently     |
| operable.                                                                    |
|                                                                              |
| A 1-hour report is required to be made to the NRC if greater than 17 offsite |
| sirens are inoperable for more than 1 hour.  All safety systems are          |
| available and operable with the exception of the 'C' station service water   |
| pump which is cleared and tagged for a system outage.                        |
|                                                                              |
| The licensee plans to notify the NRC resident inspector as well as the Lower |
| Alloways Creek Township.                                                     |
