NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date July 7, 1982 Completed By C. W. Fay Telephone 414/277-2811 i

Unit 1 operated at an average of 370 MWe net from June 1, 1982 to the end of the reporting period with no significant load re-ductions.

During the "3D Emergency Diesel Generator Annual Inspection" on June 21, 1982 the 3D emergency diesel generator output breaker, 1A52-60 to. bus lA05, failed to close under test. The breaker's failure to close was caused by a broken latch switch. The latch switch was replaced and breaker testing was resumed. Breaker lA52-60 was operated on June 9, 1982 during routine emergency diesel generator operational testing. No abnormalities in its operation were observed at that time.

In accordance with Technical Specification 15.6.9.2.A.5, a 24-hour written notice was submitted to the Region NRC Admini-strator and the Resident Inspector was notified. Further investigation is underway and will be reported in LER 82-012/0lT-0.

Other safety-related maintenance included the seal replace-ment of the Unit 1 "B" charging pump.

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-301 Unit Name Point Beach Unit 2 Date July 7, 1982 Completed By C. W. Fay Telephone 414/277-2811 Unit 2 operated at an average of 488 MWe net from June 1, 1982 to the end of the reporting period with no significant load re-ductions.

However, gross generator output for Unit 2 is at 511 MWe net, down 8 MWe net from maximum dependable capacity of 519 MWe net.

This loss is attributed to the drop in temperature caused by feedwater heater tube plugging and the subsequent bypass. Gross generation is expected to be normal when the feedwater heaters

, are replaced.

During the review and assemblage of 10 CFR 50, Appendix J Type "B" and "C" testing data for Unit 2, it was discovered that a Type "C" test of the return line check valve from the contain-ment radiation monitors was outside Technical Specification limits during ORT #65 of the 1980 refueling outage. The leakage was corrected at the time of discovery but the event was not reported.

This event is reportable in accordance with Technical Specifi-cation 15.6.9.2.A.3 (LER 82-004/01T-0).

No safety-related maintenance was performed during this period.
