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. | +------------------------------------------------------------------------------+ !!!!!!!!! THIS EVENT HAS BEEN RETRACTED.

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). | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36460 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: BRUNSWICK REGION: 2 |NOTIFICATION DATE: 11/24/1999| | UNIT: [] [2] [] STATE: NC |NOTIFICATION TIME: 13:59[EST]| | RXTYPE: [1] GE-4,[2] GE-4 |EVENT DATE: 11/24/1999| +------------------------------------------------+EVENT TIME: 12:32[EST]| | NRC NOTIFIED BY: DAVID JENKINS |LAST UPDATE DATE: 11/24/1999| | HQ OPS OFFICER: JOHN MacKINNON +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |LEN WERT R2 | |10 CFR SECTION: | | |AIND 50.72(b)(2)(iii)(D) ACCIDENT MITIGATION | | |NLCO TECH SPEC LCO A/S | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ | | | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 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. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36461 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: PERRY REGION: 3 |NOTIFICATION DATE: 11/24/1999| | UNIT: [1] [] [] STATE: OH |NOTIFICATION TIME: 14:11[EST]| | RXTYPE: [1] GE-6 |EVENT DATE: 11/24/1999| +------------------------------------------------+EVENT TIME: 10:15[EST]| | NRC NOTIFIED BY: RUSS KEARNEY |LAST UPDATE DATE: 11/24/1999| | HQ OPS OFFICER: JOHN MacKINNON +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |RONALD GARDNER R3 | |10 CFR SECTION: | | |AOUT 50.72(b)(1)(ii)(B) OUTSIDE DESIGN BASIS | | |NLTR LICENSEE 24 HR REPORT | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N Y 100 Power Operation |100 Power Operation | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | 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. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Other Nuclear Material |Event Number: 36462 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: TENNESSEE DIV.
