SUMMARY

l The following report highlights the operating experience of Wolf Creek Generating Station for the month of June, 1995. This report is being provided pursuant to Technical Specification 6.9.1.8.

I.

SUMMARY

OF OPERATING EXPERIENCE The unit operated at or near 100% power, Mode 1, from June 1, 1995, through June 17, 1995.

On June 18 at 2025, the "C" Circulating Water Pump tripped, and the Reactor subsequently stabilized at 65% power, Mode 1. The pump trip was caused by the Field Monitor Relay actuation due to a burned spot on the Field Potentiometer. On June 18, at 2115, the unit commenced increasing Reactor power, which was stabilized at 74% for troubleshooting.

Power increase commenced again on June 19, at 1201, and the plant returned to 100% power, Mode 1, at 1527 on June 19, 1995.

The unit continued to operate at or near 100% power, Mode 1, until June 28, 1995, at 0237, when power was reduced to 71%, Mode 1, in preparation for removing "B" Circulating Water Pump from service for maintenance. Power was returned to 100% power, Mode 1, at 1650 on June 28, 1995.

Power remained at or near 100% power, Mode 1, through the remainder of June, 1995.
