SUMMARY

OF OPERATING EXPERIENCE Indian Point Unit 3 was synchronized to the bus for a tota'l of 690.9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> producing a gross generation of 586,230 MWe for this reporting period. Upon completion of reactor coolant pump motor repairs, the unit was returned to service at 1444 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.49442e-4 months <br /> on December 2.

On December 3 at 0228 hours0.00264 days <br />0.0633 hours <br />3.769841e-4 weeks <br />8.6754e-5 months <br /> the plant experienced a turbine trip resulting from the indicated closure of No. 31 Main Steam Isolation Valve. The signal was generated when the limit switch indicated the valve was not fully open. The limit switch arm was realigned and adjustments were made to preclude reoccurrence.

The unit was returned to service at 1350 hours0.0156 days <br />0.375 hours <br />0.00223 weeks <br />5.13675e-4 months <br />.

At 1353 hours0.0157 days <br />0.376 hours <br />0.00224 weeks <br />5.148165e-4 months <br /> on December 3 the unit experienced a trip on high steam generator level in No. 31 steam generator. The trip occured during low power level escalation while manually controlling steam generator levels. The trip was attributed to operator difficulty.in mantaining steam generator levels in manual while escalating from low power levels. The operators commenced plant startup and returned the unit to service at 1652 hours0.0191 days <br />0.459 hours <br />0.00273 weeks <br />6.28586e-4 months <br /> that same day.
