SUMMARY

OF OPERATING EXPERIENCE Indian Point Unit 3, was synchronized to the bus for a total of 170.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> producing a gross generation of 112,440 MWe for this reporting period. The unit experienced one load reduction and two unit trips. After steam generator tube repairs, a crevice cleaning boil out of the steam generators and a hydrostatic ,

test of the reactor coolant system were performed.

On November 15 at 2208 hours0.0256 days <br />0.613 hours <br />0.00365 weeks <br />8.40144e-4 months <br />, the unit was returned to service with both main transformers operational. Commenced load escalation consistent with maintaining reactor power distribution and steam generator chemistry within required limits.

On November 19 at 1354 hours0.0157 days <br />0.376 hours <br />0.00224 weeks <br />5.15197e-4 months <br />, both heater drain tank pumps tripped due to moisture in the instrument air supply to the heater drain tank level controller resulting in a load reduction from 800 MWe to 500 MWe output. Purged heater drain tank level control transmitters and commenced plant startup. Continued load escalation and achieved 100% power level on November 20.

On November 22 at 0746 hours0.00863 days <br />0.207 hours <br />0.00123 weeks <br />2.83853e-4 months <br />, both heater drain tank pumps tripped. This resulted in a load reduction and subsequent unit trip due to a steam flow / feed flow mismatch coincident with a low level in No. 31 stam generator. The pumps tripped as a result of an instrument air orifice blockage in the level control transmitters. The orifice was cleaned and the unit returned to service at 1421 hours0.0164 days <br />0.395 hours <br />0.00235 weeks <br />5.406905e-4 months <br /> that same day. Commenced load escalation to 100% power.

On November 23 at 0447 hours0.00517 days <br />0.124 hours <br />7.390873e-4 weeks <br />1.700835e-4 months <br />, the plant experienced a unit trip on loss of RCS loop flow when #31 Reactor Coolant Pump tripped on a phase imbalance relay signal. Investigation indicated a stator fault on the reactor coolant pump motor. Replaced stator on motor and commenced plant startup.
