NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No.

50-266 Unit Name Point Beach Unit 1 Date March 7, 1989 Completed By C. W. Krause Telephone 414/221-2001 Unit 1 operated at approximately 495 MWe net throughout the period with no shutdowns or significant load reductions.

The unit commenced end-of-core life operations on February 18.

On February 22, the plant conducted an Emergency Plan drill in preparation for the upcoming March 15 exercise.

On February 7, the Unit 1 "B" reactor trip breaker failed to close (conservative) during safeguards testing.

Maintenance personnel discovered a blown negative fuse.

Investigations revealed no evidence of further problems.

The fuse was replaced and the breaker was restored to operation later that same day.

Other safety-related maintenance included a gasket replacement to repair an oil leak on auxiliary feed pump P38B inboard bearing sightglass and the replacement of four circuit breakers in 125 V DC distribution panels D11 and D13 in response to IE Bulletin 88-10.

La NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No.

'50-301 Unit Name Point Beach Unit 2 Date March 7, 1989 Completed By C. W. Krause Telephone 414/221-2001 Unit 2 operated at approximately 500 MWe net throughout the period with no shutdowns or significant load reductions.

On February 3, a two percent Unit 2 runback occurred while operators were transferring power supplies to the " white" instrument Bus 2YO3.

During the transfer, the power supply was momentarily lost.

The loss of power initiated a spurious safeguards signal and an' automatic turbine runback.

Prompt operator action restored the instrument bus power supply, and the unit returned to full power operation.

Licensee Event Report 89-001 has been submitted to detail the event.

i Safety-related maintenance completed during the period included minor repairs to 2P10A residual heat removal pump seal leakoff drain line and repairs to main steam non-return check valve 2-2018A counter weight.
