One minor turbine runback occurred on December 20.
The runback was initiated by a failed isolation transformer on the yellow instrument bus.
The plant returned to full power approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> later.
Licensee Event Report 85-010 was written to document the circumstances of the event.
Primary-to-secondary leakage
. remains stable at less than 10 gallons per day.
On December 19, Unit 1 surpassed 48 billion kilowatt hours.
Other maintenance completed included the annual overhaul of G02(4D) emergency diesel generator.

SUMMARY
OF OPERATING EXPERIENCE Docket No.
50-301 Unit Name Point Beach Unit 2 Date January 7, 1986 Completed By C.
W.
Krause Telephone 414/277-2001 Unit'2 achieved full power for the first time during the post-refueling period at 5:17 PM on December 3.
Full power operation was not achieved sooner because of the following requirements or conditions which developed:
High conductivity in secondary system coolant, Reactor Engineering tests, and nuclear fuel conditioning.
On December 4, at 11:50 AM, smoke was detected in the control building computer room.
The smoke originated from failed 4 instrumentation transformer 2XY01.
The fire brigade responded and deenergized the transformer.
Repairs were completed and the instrument transformer was restored to service.
The unit operated at approximately 494 MWe net throughout most of the reporting period with the exception of two short outages.
On December 27, a small crack was found in a weld on a component cooling water line to the Unit 2 "A"
reactor coolant pump lube oil cooler.
The crack was dripping at approximately 4 gallons per hour.
This component cooling line cannot be isolated without taking the unit off line and securing the reactor coolant pump.
Load reduction commenced at 9:00 PM on December 27 and the generator was off line at 3:30 AM on December 28.
By 12:45 PM, the crack was repaired and successfully hydrotested.
The unit was back on line at 12:46 AM on December 29.
Load was held at approximately 150 MWe net for 27 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br /> because of high steam generator cation conductivity.
The unit was back at full power at 9:13 AM on December 30.
On December 31, at 4:26 AM, the unit tripped because of a phase-to-ground fault in the A0 lightning arrester of switchyard bus Section 4.
No fast bus transfer of power supply to the A01 and A02 non-vital 4160 kV buses occurred because they did not synchronize with their alternate power supply during the electrical transient.
This resulted in both reactor coolant pumps and secondary plant electrical auxiliary being deenergized.
A01 and A02 were manually reenergized and equipment was restarted to operate the plant in the hot shutdown condition.
At 4:55 AM, an unusual event was declared as required by the Emergency Plan for a loss of electrical load.
The appropriate agencies were notified of the event.
The unusual event was terminated at 6:24 AM after the cause of the transient was determined.
., The 4160 V auto bus transfer was tested te verify no electrical malfunction had occurred in the circuitry.
By_4:40 PM, bus Section 4 in the switchyard was restored to normal.
The unit returned to power on the following day.
Licensee Event Report 85-005 was written to document the event.
Primary-to-secondary leakage remains less than ten gallons per day.
