NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date December 10, 1981 Completed By C. W. Fay Telephone 414-277-2811 Unit 1 remained shut down throughout the period during its ninth refueling outage. Major work items performed during this period included the following.

Eddy current examination of Unit 1 "A" and "B" steam generator U-tubes was completed on October 30. A total of ten tubes in "A" steam generator and seven tubes in "B" steam generator required plugging. The tube degradation discovered during the eddy current tests is reportable in accordance with Technical Specification 15.6.9.2.A.3 (LER 81-017/OlT-0) .

The demonstration sleeving project on the "A" steam l generator commenced on November 1 following decontamination of' the hot leg side of the steam generator channelhead. On November 3, l

j tube plugs were removed from each end of six previously plugged i

tubes. A total of 12 tubes, including six tubes with defects exceeding the plugging limit, were successfully sleeved during the period November.4 through 11.

The "B" reactor coolant pump casing weld inspection-commenced on November 2. The examination was completed on November ~12' with no reportable indications.

The ultrasonic examination of the reactor vessel commenced on November 20. The examination was completed on November 21 with no reportable indications.

Fuel loading commenced on November 23 and was completed on November 25. The upper internals package'was replaced on November 25. The reactor vessel head assembly was replaced on November 27. The reactor vessel head studs were replaced on November 28 and tensioned on November 30.

Turbine. overhaul and reassembly continued throughout the period.

Safety-related maintenance throughout this period included sleeving of "A" steam generator; tube plugging in both "A" and "B," steam generators; disassembly, seal overhaul, and reassembly of the "B" reactor coolant pump; installation of reactor vessel level instrumentation tap-off connections and a reactor vessel head vent tap-off> connection; inspection, overhaul, and reassembly of various safety-related valves; overhaul of both residual heat removal pumps; weld repair of a previously peened control rod. drive mechanism seal weld; and repair of a large seismic snubber.

For a period of approximately two and one-half hours on October 16 and into October 17, the plant smoke detector system was inoperable. An error in wiring during backfitting of the fire protection system caused fuses to blow and de-energization of the system. The event has been determined to be reportable in accordance with Technical Specification 15.6.3.2.B.2 (LER 81-018/03L-0).
