NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE DOCKET NO.

50-266 UNIT NAME Point Beach Unit 1 DATE February 5, 1979 COMPLETED BY Wisconsin Electric Power Company Point Beach Nuclear Plant generated its 50 billionth kilowatt hour of electricity at 3:15 a.m.,

January 5, 1979.

Units 1 and 2 had generated 27.5 and 22.5 billion kilowatt hours, respectively.

During the month of January, Unit I was base loaded for approximately 97% of the period with five load reductions.

Freezing of the circulating water intake crib necessitated 114 hours0.00132 days <br />0.0317 hours <br />1.884921e-4 weeks <br />4.3377e-5 months <br /> of reduced power operation for Unit 1.

After indications of freezing became evident at 2:50 a.m.,

January 2, 1979, Unit 1 load was reduced to 230 MWe for about five hours.

When freezing problems continued, Unit 1 load was reduced to 95 MWe for one hour and finally to 70 MWe for about two hours.

Beginning around 11:00 a.m.,

the freezing problems were gradually overcome and return to full load was commenced about noon.

Unit 1 achieved full power at 2:17 p.m.,

January 2, 1979.

Power Supply requested that load be reduced to 365 MWe for five hours on January 1, 1979.

Load was reduced to 470 MWe for about ten minutes on January 5, 1979, when the "B" heater drain tank pump discharge check valve stuck open and caused a partial loss of main feed pump suction precsure.

The load was reduced to provide some operating margin above the low feed pump suction pressure trip setpoint until the heater drain tank pump could be manually isolated.

Load was reduced to 350 MWe for two hours on January 8, 1979, to conduct turbine stop valve tests.

Load was reduced to 465 MWe for ten minutes on January 16, 1979, to conduct inservice tests of the pressurizer power operated relief valves.

Primary-to-secondary leakage in the "A"

steam enerator s

gradually increased from 43 to 56 gallons per day over the period.

No major safety related maintenance was performed during the period.

50-301 UNIT NAME Point Beach Unit 2 DATE February 5, 1979 COMPLETED BY Wisconsin Electric Power Company Point Beach Nuclear Plant generated its 50 billionth kilowatt hour of electricity at 3:15 a.m.,

January 5, 1979.

Units 1 and 2 had generated 27.5 and 22.5 billion kilowatt hours, respectively.

During the month of January, Unit 2 was base loaded for approximately 99% of the period with six load reductions.

Freezing of the circulating water intake crib made it necessary to reduce Unit 2 load to 295 MWe for one and one-half hours on January 2, 1979.

Load was reduced to 345 MWe for one hour on January 16, 1979, to conduct turbine stop valve tests.

Load was reduced to 470 MWe for one-half hour on January 18, 1979, to test the "A" atmospheric steam dump valve.

Load was reduced to 465 MWe for abcat one-half hour on January 26, 1979, to isolate the "A" and "C" moisture separator reheaters in order to repair a body-to-bonnet leak on the "A" moisture separator reheater steam purge valve (used for initial moisture separator reheater warmup).

The repair was completed and the moisture separator reheaters were restored to service later that same day.

Unit load was manually run back to 395 MWe for about one-half hour on January 26, 1979, in anticipation of low feed pump suction pressure during an unexplained condensate system pressure transient.

Full power was resumed when conditions returned to normal.

Load was reduced to 470 MWe for 15 minutes on January 28, 1979, to test the "B" atmospheric steam dump valve.

Twenty four of the 36 new fuel assemblies for the upcoming refueling arrived in two shipments received on January 18, 1979, and January 25, 1979.

No major safety related maintenance was performed during the period.
