NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No.

50-266 Unit Name Point Beach Unit 1 Date May 5, 1986 Completed By C. W.

Krause Telephone 414/277-2001 Unit 1 operated at approximately 494 MWe net from the start of the period until April 12, 1986, when the unit was shut down to commence refueling and maintenance outage No. 13.

Significant maintenance items being completed during the outage include replacement of both trains of the Nos. 1, 2, 3, and 5 feedwater heaters, modifications to the moisture separator reheater internals, replacement of the Unit 1 plant process control computer (P-250), condenser tube replacement, the replacement of power range detectors NE-42 and NE-43 and the upgrade of the control circuits on 20 environmentally qualified valve motor operators.

Eddy current testing in the steam generators was completed and no pluggable indications were discovered.

Fuel motion has been completed.

Evidence of baffle jetting was discovered on one fuel

. assembly which was removed during the fuel shuffle.

The assembly

~had been in core location D12.

The fuel assembly which had been in that location the previous cycle also had failed fuel rods.

Hardware and wiring problems encountered during the startup of the new oxygen gas analyzer have been resolved and the system has been declared operational.

On April 17, 1986, during Operations refueling testing, component cooling water supply check valve 1-755A to the reactor coolant pump s'als was discovered with excessive back leakage.

Maintenance was e

completed and the valve retested satisfactorily. ' Licensee Event Report 86'-002'is being written to further document the event.
