SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date December 7, 1989 Completed By C. W. Krause

, Telephone 414/221-2001 Unit 1 operated at approximately 494 MWe net throughout the

! period with no major load reductions.

On November 7, 1989, it was discovered that the Point Beach Nuclear Plant was in a condition which was outside.of the requirements of TS 15. 3. 7.B.1. f and 15. 3. 7.B.1.g . These TS state:

L "15.3.7 B.1.f: One of the batteries, DOS or D06, may be inoperable for a period not exceeding 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months provided the other three batteries and four battery chargers remain operable with one charger carrying the DC loads of each DC main distribution bus."

"15.3.7.B.1.g: One of the batteries, D105 or D106, may be inoperable for a period not exceeding 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months provided the other three batteries and four battery chargers remain operable with one charger carrying the DC loads of each DC main distribution bus."

On November 9, 1989, at 1600 hours0.0185 days 0.444 hours 0.00265 weeks 6.088e-4 months , the PBNP Manager's Supervisory Staff determined that the DOS and D06 station batteries were technically inoperable as a result of the discovery of an original plant design deficiency which could render one or both of the two plant main DC systems inoperable as a result of a single bus fault. The potential problem had been reported to the manager - PBNP at 1200 hours0.0139 days 0.333 hours 0.00198 weeks 4.566e-4 months by our corporate l headquarters Nuclear Engineering group. Upon arrival at the plant site approximately two hours, the issue was presented to the Manager's Supervisory Staff. LER 89-009 was written to document this incident.

1 During the steam generator crevice flush, the steam generator i specific auxiliary flow indicators from the aux feed line into the steam generator were supposed to be isolated. The flow indicators from Unit 1 were isolated rather than Unit 2. They were left in i this condition for more than 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months . This is a condition L prohibited by Technical Specifications. LER 89-010 is being l drafted to document this incident.

SUMMARY

OF OPERATING EXPEPIENCE i-Docket No. 50-301 Unit Name Point Beach Unit 2 Date December 7, 1989 Completed By C. W. Krause Telephone 414/221-2001 The Unit 2 refueling and maintenance outage was completed November 25, 1989, when the unit was phased back on line. The '

unit'was taken off line for about one hour during the turbine overspeed testing and was phased back on at 9:32 p.m. on November 25, 1989.

Major work completed includes replacement of D06 station battery, replacement of the B main feedwater pump, performance testing of the D105 and D106 station batteries, and repair and replacement of damaged low pressure turbine blades.

On November 3, 1989, during refueling operations, contractor personnel generated a false trip signal while investigating a wiring discrepancy in the reactor protection system instrument >

racks. The reactor was defueled and the reactor trip breakers were open. Therefore, no safety-related equipment started.

An original wire labeling error was considered the root cause of '

the event.- LER 89-008 was written to document this event.

During the test of the emergency lighting, a lighting breaker was opened as a part of the test. At the same time the steam generator level indication was being tested and an " artificial" steam generator level generator was plugged into a lighting receptacle. The breaker opened for the emergency lighting also supplying power for the steam generator level generator. When the breaker was opened, the steam generator level lost power and indicated a "no level" in the steam generator. This caused a trip signal to be generated. LER 89-009 is being drafted to document this event.
