SUMMARY

OF OPERATING EXPERIENCE SEPTEMBER 1986 Indian Point Unit #3 returned to service on September 10, 1986 at 1201 hours0.0139 days <br />0.334 hours <br />0.00199 weeks <br />4.569805e-4 months <br /> following a 61 day turbine maintenance outage. For the remainder of the reporting period Indian Point Unit # 3 was synchronized to the bus for a total of 548.05 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, producing a gross generation of 471,680 Mwe.

On September 05 at 1558 hours0.018 days <br />0.433 hours <br />0.00258 weeks <br />5.92819e-4 months <br />, a control circuit ground fault on a motor operated disconnect switch of a generator transmission line in the Buchanan switchyard opened while the unit was operating at 56 percent power. A main turbine generator trip and a subsequent reactor trip occurred automatically.

. An investigation determined that the grounds resulted from moisture that had entered underground conduit. To prevent recurrence, new conduit and wiring wer,e installed for the control circuitry and maintenance was performed on the junction boxes. The unit returned to service on. September 8, 1986 at 0107 hours0.00124 days <br />0.0297 hours <br />1.76918e-4 weeks <br />4.07135e-5 months <br />.

On September 09, 1986 at 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br />, an automatic unit trip was initiated by low steam generator water level which was caused by the tripping of f 31 Main Boiler Feed Pump. Water entering the Main Boiler Feed Pump control oil system caused imbalances in the hydraulic' controls and caused #31 Main Boiler Feed Pump to

' trip. The oil system was cleaned and a mispositioned Boiler Feed Pump seal was monitored to verify that it would perform as designed by automatically self-seating during pump operation.

The unit was returned to service on September 10th at 1201 hours0.0139 days <br />0.334 hours <br />0.00199 weeks <br />4.569805e-4 months <br /> and continued to produce electricity for the remainder of the reporting period.
