Summary of Operating Experience August - 1979 Indian Point Unit 3 was synchronized to the bus for a total of 744 hours0.00861 days <br />0.207 hours <br />0.00123 weeks <br />2.83092e-4 months <br />, producing a gross generation of 469,420 mwh for this reporting period. During this period, the unit experienced 2 trips,1 load reduction and the setting of a new site record for continuous operation.

On August 8th at 12:35 the unit tripped due to a transformer fault on B & C phase bushings on #31 main transformer. At the time of this trip, the unit had been operating continuously since April 10th at 23:39, setting '

new site record of 119 days, 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and 56 minutes of operation. The transformer was isolated and the unit was able to return to service at half load on August 9th at 21:12. On August 17th 'at 10:25, a unit trip occurred due to a ground in the turbine trip circuitry. While .the unit was down #31 main transformer which had been repaired was reconnect'ed and the unit was returned to service on August 18dh at 10:42.

On August 21st, at 16:00 load was reduced due to the removal of two circulating water pucps because of condenser leaks. Load was increased to approximately 780 mw on August 22nd at 2000 after repairs were effected and remained that way until August 31st when condenser leaks again caused a load reduction. Load was reduced to 450 mw.
