NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date February 5, 1980 Completed By C. W. Fay Telephone 414/277-2811 Unit 1 was base loaded for 75% of the period with two load reductions.

Load was reduced to 320 MWe net on January 4, 1980, for approximately nine hours for repair of the 1B condensate pump, and again on January 27, 1980, to 285 MNe net for five hours to facilitate turbine stop valve testing. The unit has been operating at a slightly reduced efficiency because of increased circulating water temperatures caused by ice melt operation.

On January 4, 1980, the reactor coolant system operating pressure was reduced from 2235 psig to 1985 psig to comply with NRC instructions on low pressure operation. The pressure was reduced in order to reduce the differential pressure acrosn the steam generator tubes, thus reducing metal stresses and consequently reducing the possible inducing of further tube leakage. Unit primary-to-secondary leakage has remained stable at approximately 30 gallons per day during the period.

Replacement of the "B" condensate pump seal was performed during the period.

A site evacuation emergency plan drill was conducted on January 14, 1980. A critique of the drill was conducted by the Manager's Supervisory Staff on February 4, 1980.

All of the spent fuel has been moved to the newly reracked north spent fuel pit.

The unit "B" reactor coolant pump seal leakage has been below normal for the duration of this period, but is stable and at a sufficient level to provide adequate seal lubrication along with cooling to the pumps lower bearing. The leakage rate is being closely nonitored by operating personnel.

Work continues on IE Bulletin Nos. 79-02, anchor bolt inspection, and 79-14, seismic analysis for as-built safety related piping systems.

No other major safety-related maintenance was performed during the period.

NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docke t No . 50-301 Unit Name Point Beach Unit 2 -

Date February 5, 1980 Completed By C. W. Fay Telephone 414-277/2811 Unit 2 was base loaded for 96% of the period with five load reductions.

Unit load was reduced on January 3,1980, and again on January 9, 1980, to 470 MNe net for one hour to remove the SB feedwater heater from service; on January 6, 1980, to 250 MNe net for seven hours for condenser tube plugging; on January 12, 1980, to 435 MNe net for 16 nours to maintain 345 KV system stability while line 111 was out of service; and on January 13, 1980, to 475 MNe net ft,r one hour to allow testing of the crossover steam dump system. The unit has been operating at a slightly reduced efficiency because of increased circulating water temperatures caused by ice melt operation.

All the new fuel bundles necessary for the unit refueling in April,19 80, (Refueling 6) have been received, inspected, and placed in storage.

Work performed on the 5B feedwater heat exchanger while it was out of service included rewelding of a leaking patch on the tubesheet and repair of a leaking isolation valve on the level transmitter manifold.

Charging pump maintenance work during the period included cleaning the 2C charging pump motor commutator and replacement of the " A" charging pump block we.ich was found to be cracked. The Unit 2 "A" charging pump block was the last of the origina1 plant charging pump blocks. The recent -

addition of suction line stabilizers to these pumps should greatly reduce or eliminate the incidence of block cracking.

Work continues on IE Bulletin Nos. 79-02, anchor bolt inspection, and 79-14, seismic analysis for as-built safety related piping systems.

No other major safety-related maintenance was performed during the period.

2 On January 17, 1980, the recent installation of instrument bus AC/AC motor-generator units proved to be a valuable plant modification as they kept the plant from tripping when the nearby Kewaunee Nuclear Plant tripped of f line due to an auxiliary transformer failure. The motor generator units prevented the sh 't duration line fault of approximately 1800 amps caused by t trip from affecting the instrument busses and possibly tripping the Point Beach units.
