The dropped rod indication aute natically initiated a turbine runback. During the runback, the unit tripped on steam / feed flow mismatch coincident with a low level in No. 32 steam generator. The sole-noid coil was replaced and startup was commenced.

SUMMARY

OF OPERATING EXPERIENCE Indian Point Unit 3 was synchronized to the bus for a total of 727.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> producing a gross generation of 609,630 MWe for the reporting period.

One trip and two load reductions were experienced during this period.

On January 4, at 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> the plant experienced a turbine runback and subsequently a unit trip on a steam flow-feed flow mismatch coincident with low level in No. 32 Steam Generator. A voltage spike on No. 32 instrument bus, which was generated by a short circuit on a weld channel and containment press-urization system solenoid valve caused the activation of the dropped rod circuitry.

This initiated the runback which resulted in the trip.

The solenoid coil was replaced and plant startup was commenced.. On January 5, at 1220 hours0.0141 days <br />0.339 hours <br />0.00202 weeks <br />4.6421e-4 months <br /> the generator was sychronized to the bus and commenced power escalation consistent with maintaining flux difference within target band.

On January 12, at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> commenced load reduction after experiencing an intermittent spike on a reactor protection channel. An investigation led to replacir.y the resistance temperature converter associated with No. 34 RCS loop hot leg. Lepairs were completed and at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> the unit was returned to full load.

On January 26, at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> commenced load reduction to allow the removal of #32 condensate pump from service for repairs.
