Summary of Operating Experience December 1978 Indian Point Unit 3 was synchronized to the bus for a total of 562.95 hour0.0011 days <br />0.0264 hours <br />1.570767e-4 weeks <br />3.61475e-5 months <br /> $ producing a gross generation of 536,480 mwe for this reporting period.

During the reporting period, the unit experienced a shutdown, load reduction and a trip.

The shutdown occurred on December 7 at 0915. Steam jet air ejector discharge and necondary water samples indicated a steam generator tube leak. Upon verification of activity levels, the operator immediately started a 150 mwe/hr load reduction. The unit was removed from service at 15:22. The problem was isolated to a single leaking tube in No. 33 steam generator. The tube was plugged and the unit returned to service at 20:50 on December 14, 1978. A delay was encountered unile bringing the unit up to full power. Main boiler feed pump #32 would not come up to speed due to problems in the control oil system. After the problems were solved the pump was returned to service and load was increased to full power at 03:30 on December 16.

On December 16 at 05:20 #32 main boiler feed pump tripped and load was reduced to 800 mwe. The cause of the boiler feedwater pump trip was attributed to dirt in the governor control system. The dirt was removed and the unit was returned to full load at 11:00 of the same day.

The unit experienced a reactor trip during this period. At 21:08 on December 18, the unit tripped on #33 low steam generator level. The cause of the problem 'ias the loss of #32 boiler feed pump. Subsequent investigation did not reveal any problems with the' feed pump. The unit was.rcturned to service at 04:43 on December 19, 1978. .
