SUMMARY

OF OPER ATING EXPERI ENCE 11-01-86 At the beginning of the month the Duane Arnol d Energy Center (DAEC) was operating at 100% of rated power with 535 MWe (Net) being provi de d to the j

grid.

11-04-86 At 0333 hours0.00385 days 0.0925 hours 5.505952e-4 weeks 1.267065e-4 months a 7 day Limiting Con dition for Operation (LCO) was entere d when the Reactor Core Isolation Cooling (RCIC) system was de c l a r e d Inoperable. The control room RCIC pump outlet flow meter was not respon ding to actual KCIC pump flow variations during the quarterly RCIC Surveillance test.

The flow meter was replaced and the RCIC system was returned to service after successful completion of the quarterly test.

The 7

LCO was then terminated at 0010 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months on 11-05-86 (LER 86-023) i At 0810 hours0.00938 days 0.225 hours 0.00134 weeks 3.08205e-4 months the

'A' train of the Control Buil ding Standby Filter Units (SFU) was dec l a r e d inoperable.

This placed the plant in a7 day LCO.

The flow in dicating controller was recalibrated and the LCO was terminated at 1249 hours0.0145 days 0.347 hours 0.00207 weeks 4.752445e-4 months on 11-06-86 with the system being returned to its normal stan dby status.

l 11-12-86 The

'A',

'B',

'C',

and

'O' trains of the Main Steam Line isolation -

through Leakage Control System (MSlV-LCS) were remove d f rom service at different 11-13-86 times for the yearly calibration of the flow transmitters. This placed the I

plant in and out of four 30 day LCOs.

The final LCO was terminated at 1352 hours0.0156 days 0.376 hours 0.00224 weeks 5.14436e-4 months on 11-13-86 with the

'D' train placed back in service, 11-14-86 At 1225 hours0.0142 days 0.34 hours 0.00203 weeks 4.661125e-4 months the final shipment of the new fuel was placed on the refuel floor.

11-17-86 At 1545 hours0.0179 days 0.429 hours 0.00255 weeks 5.878725e-4 months a7 day LCO was entered when the diesel fire pump was remove d from service in order to perform major overhaul work on the di es e l engine.

The engine was sent offsite for a complete engine overhaul. The system was returne d to service following successful post-maintenance testing at 1331 hours0.0154 days 0.37 hours 0.0022 weeks 5.064455e-4 months on 11-24-86 The LCO was terminated at this time.

11-18-86 At 0236 hours0.00273 days 0.0656 hours 3.902116e-4 weeks 8.9798e-5 months the

'A' Res i dua l Heat Removal Service Water (RHRSW) pump was dec l a r e d Inoperable when a vlbration pad f ell off the pump du r i n g surveillance testing.

This placed the plant in a 30 day LCO.

The LCO was cancelod at 0155 hours0.00179 days 0.0431 hours 2.562831e-4 weeks 5.89775e-5 months on 11-19-86 after replacement of the vlbrotlon pad and completion of the surveillance test.

From 1800 to 2400 hours0.0278 days 0.667 hours 0.00397 weeks 9.132e-4 months the 1906 NRC observe d Emergency Preparedness Drill was con ducted at DAEC.

11-19-86 At 0748 hours0.00866 days 0.208 hours 0.00124 weeks 2.84614e-4 months a7 day LCO was entered when the

'A' train of the S tan dby Ga s l

Treatment System was removed from Service for planne d main tenance.

A Temperature Transmitter was callbrated and the system returned to service i

at 1755 hours0.0203 days 0.488 hours 0.0029 weeks 6.677775e-4 months on 11-20-86 The LCO was exitod at this time.

SUMMARY

OF OPERATING EXPERIENCE 11-20-86 At 1520 hours0.0176 days 0.422 hours 0.00251 weeks 5.7836e-4 months the 'A8 train of the RHR system was dec l a r e d inoperable when a snubber on the system was f oun d to be low on fluid.

A 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months LCO was entered to replace or restore the snubber to its operable status, and perform an engineering evaluation.

The fluid level was restored an d the snubber was declered operable on 11-21 at 1810 hours0.0209 days 0.503 hours 0.00299 weeks 6.88705e-4 months .

11-21-86 At 0822 hours0.00951 days 0.228 hours 0.00136 weeks 3.12771e-4 months the HPCI System Isolated when a spurious isolation signal was received f rom a Dif f eren+1al Pressure Switch which senses high steam flow.

Investigation revealed moisture in the switch compartment, which likely resulted in a momentary short of contacts at the contact block.

The switch compartment was deled and recalibrated successf ully.

Following completion of the HPCI operability test, the HPCl was declared operable at Ol19 hours on 11-22-86 The LC0 was exited this time.

(LER 86-024) 11-25-86 At 0700 hours0.0081 days 0.194 hours 0.00116 weeks 2.6635e-4 months a 7 day LCO was entered when the 808 SOGT System was remove d from service for planned maintenance.

During this maintenance the flow in dlcating controller was f ound not to be callbrating properly and was rep lace d.

The LCO was exited at 1728 hours0.02 days 0.48 hours 0.00286 weeks 6.57504e-4 months with the system belno returned to service.

11-26-86 At 0815 hours0.00943 days 0.226 hours 0.00135 weeks 3.101075e-4 months the Diesel Fire Pump was removed from service for pump repacking. The plant entered a 7 day LCO at this time.

The pump was repacked and returned to service at 1437 hours0.0166 days 0.399 hours 0.00238 weeks 5.467785e-4 months on 11-29-86 The LCO was terminated at this time.

11-30-86 The OAEC was operating with all ro ds full out at the end of the month.

Coa s t dow n towar d the cycle 8/9 Ref uel Outage had started in ml d November.

The plant was operating at 91% of rated thermal power with 487 MWe (Net) being provi de d to the grld.
