Unit 1 operated at-approximately 363 MWe net throughout-F

.the period with.no significant load reductions.

This is less than last month's_ average generation due to condenser high inlet temperatures.

The primary-to-secondary leakage remains stable at less than 10 gallons per day.

SUMMARY

OF OPERATING EXPERIENCE Docket No.

50-301 Unit Name Point Beach Unit 2 Date September 7, 1983 Completed By C. W. Fay Telephone 414/277-2811 Unit 2' operated at approximately 483 MWe net throughout the period with one significant load reduction.

On August 3, 1983, the unit tripped due to a valve failure in the "A" RTD bypass manifold.

This resulted in an overpower AT condition being sensed by instrumentation.

After repairs to the valve were complete, the unit came back on line August 5, 1983, and was at fidl power at 0906 hours0.0105 days <br />0.252 hours <br />0.0015 weeks <br />3.44733e-4 months <br /> the same day.

The average gener-ation was less than last month's due to condenser high inlet temperatures.

On August 17, 1983, inservice testing of the "B" residual heat removal pump showed excessive vibration in the pump.

The plant was placed in a 24-hour limiting condition for operation while maintenance was performed.

A 30-day report will be sub-mitted.
