Unit Name Point Beach Unit 1 Date September 4,19 81 Completed By C. W.

Fay Telephone 414/277-2811 Unit 1 load reducti n fu.m 415 MWe net was commenced at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> on July 31, ?2^'.

in preparation for a containment leak inspection.

Cont..r ent air particulate monitors had been indicating higher tnan the normally low activity levels since returning to power af ter the July outage so it was decided to take the unit off line and hold in hot standby to assist in the detection of sources of leakage.

Previous inspections into available areas during power operation could not identify the source.

Three minor packing leaks were discove red.

The leaks were stopped by tightening the packing and the unit was back on line at 1034 hours0.012 days <br />0.287 hours <br />0.00171 weeks <br />3.93437e-4 months <br /> on August 1, 1981.

However, there was little change in the level of containment particulate activity, meaning the packing leaks were not the cause of the high levels.

An investigation of the cause is continuing.

The activity level has dropped off slightly and remained stable.

For the remainder of the period, Unit 1 operated at 415 MWe net with two load reductions.

On August 16, 1981, Unit 1 experienced a two-hour load reduction for steam dump testing and on August 22, 1981, load was reduced to 310 MWe net for five hours for turbine stop valve testing.

On August 28, 1981, two DC circuit breakers were accidentally opened by contractor personnel on control panel C01.

One breaker supplied alarm and control functions of the 4D Diesel day tank and the other breaker supplied control power to the lockout relay which strips nonessential loads from IB04 480 volt "B" train safeguards bus upon a safety injection signal.

The breakers were open for a period of approximately 20 minutes before operators could determine the source of the " critical control power failure" alarm which was received on the control panel following the opening of the bre ake rs.

This condition sas evaluated as being reportable in accordance with Technical Specification

15. 6.9. 2. A.6 and a 14-day report, Licensee Event Report No.

81-012/0lT-0, will be filed.

There was no safety-related maintenance performed during the period.

Later the sane day at 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load was further reduced to 270 MWe to repair the 2A feed pump.

On August 16, 1981, load was reduced to 460 MNe for two hours while the SA Sedwater heater was taken out of service for inspection and repair.

On August 3, 1981, during a routine calibration check of pressurizer level instrumentation, it was found that one of three channels had drifted beyond the range allowed by Technical Specifications.

The instrument was adjusted and returned to service.

This event was reported in Licensee Event Report No. 81-006/03L-0.

There was no safety-related maintenance performed during the period.
