| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS (24-hour |
| report) |
| |
| The following text is a portion of a facsimile received from Paducah: |
| |
| "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." |

EVENT TEXT

| 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. |
| |
| * * * RETRACTION ON 11/24/99 AT 1907 EST FROM THOMAS J. LANDIN TAKEN BY |
| 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. |

| REACTOR CORE ISOLATION COOLING (RCIC) FLOW INDICATOR FAILED LOW. |
| |
| The RCIC system was declared inoperable due to a flow indicator failing |
| downscale (below zero). The indication was noted while the system was in |
| standby. The plant is in a 14-day limiting condition for operation. |
| Troubleshooting efforts are in progress. |
| |
| The licensee notified the NRC resident inspector. |
| |
| *************** UPDATE AT 1005 EST ON 11/24/99 FROM TIM ROGERS TO LEIGH |
| TROCINE *************** |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "This notification retracts a notification made on 11/17/99 due to RCIC flow |
| indicator down scale. Investigation of the RCIC flow indication and control |
| loop showed the loop was operable. RCIC was operable until removed from |
| service for the investigation." |
| |
| "The apparent down scale condition of the RCIC flow indicator was the result |
| of instrument drift (zero shift) of the flow transmitter, FT-13-58. The |
| zero shift resulted in an apparent downscale condition at no flow, but [it] |
| would not have prevented the system from providing required flow at nominal |
| operating conditions. The flow transmitter would have provided operations |
| with correct readings during RCIC operation. The flow transmitter was |
| calibrated to required tolerances, and the system [was] returned to normal |
| standby conditions." |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R3DO (Gardner). |

| REACTOR CORE ISOLATION COOLING (RCIC) TURBINE TRIPPED ON HIGH EXHAUST |
| PRESSURE DURING POST-MAINTENANCE TESTING. |
| |
| 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. |
| |
| The NRC resident inspector was notified of this event by the licensee. |

| TRAIN 'A' STANDBY LIQUID CONTROL SYSTEM AGASTAT RELAY SEISMIC RESTRAINT |
| FOUND UNCLIPPED. |
| |
| 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). |
| |
| The NRC resident inspector was notified of this event by the licensee. |

| GTS CONFISCATED TWO FIREFIGHTER'S COATS, PANTS, AND GLOVES AS A PRECAUTION |
| AFTER THEIR CLOTHING TRIGGERED THE PCMs. |
| |
| The following Agreement State report was faxed to the NRC Operation Center: |
| |
| "[The Tennessee Department of Environment and Conservation - Division of |
| Radiological Health] was notified by the Tennessee Emergency Management |
| Agency (TEMA) of a fire at GTS Duratek, a waste facility. Two employees |
| 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 |
| contaminated. All monitors functioned properly, and negative pressure was |
| maintained. There were no releases to the environment." |
| |
| "GTS confiscated the two firefighters' coats, pants, and gloves as a |
| precaution after their clothing triggered the PCMs. A survey of the |
| clothing indicated minimal contamination, and it will be resurveyed after it |
| dries. GTS personnel were not injured nor contaminated. The damage was |
| limited to replacement of filter cartridges. The Radiation Safety Officer |
| issued a stop work order until an investigation is completed." |
| |
| "These events do not pose a threat to public health and safety but are |
| reportable under 1200-2-5-141(2)(c)4.(ii) of State Regulations for |
| Protection Against Radiation." |
| |
| "Three local television stations reported the fire. [There was no coverage |
| by] print media." |
| |
| The Tennessee event report number assigned to this event is TN-99-164. |
| |
| Call the NRC operations officer for a contact name and telephone number. |

| 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. |
