SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date March 5, 1984 Frepared By C. W. Fay Telephone 414-277-2811 Unit 1 completed weeks 19 through 22 of the refueling and steam generator replacement outage. On February 5 the secondary side of both steam generators was hydrostatically tested satisfactorily.

On February 7 and 8 preparations ' tere being completed for the primary side hydrostatic test. The only significant problems of note were the chemistry problems that occurred while filling the steam generators and the reactor coolant system. Water in one steam generator contained a high level of chlorides while the reactor coolant system contained high levels of oxygen. The primary system problems were believed to have been caused by the initial passivation of the new metals in the steam generators.

The correction of these chemistry problems caused the preparations for the primary side hydrostatic test to be extended 1-1/2 days.

On February 8 the primary side hydrostatic test was completed satisfactorily. Leak tests were also completed satisfactorily on the safety injection system, residual heat removal system, and the containment spray system.

Inspection of the control rod drive guide tube split pins was completed during the period. Of the 74 pins inspected (100%),

67 of them had crack indications on the pin shanks. All the split pin leaves were accounted for. A visual inspection of the nuts on the split pins was conducted and three nuts, at locations G3, I5, and K7, were found missing and have not been located.

Evaluations are being done by Westinghouse and Wisconsin Electric engineers to assure that Unit 1 can be safely operated.

Planning is under way to replace the split pins at a future Unit 1 refueling outage.

On February 18 one bent and one broken control rod drive shaft guide tube flexure pin was removed from rod positions E9 and Ell for inspection in accordance with Westinghouse recommendations.

Discussions with Westinghouse have concluded that the failure of the split pins and flexure pins is due to material and stresses induced during fabrication and installation.

Results of the par examination that occurred during the period showed four indications on the "A" hot leg nozzle and seven indications on the "B" hot leg nozzle. On the "A" hot leg nozzle one indication was in the root of the nozzle-to-shell weld and one indication was greater than Code limits. On the "B" hot leg nozzle one indication was greater than code limits. Southwest Research Institute is performing a fracture mechanics analysis.

Point Beach Unit 1 l l of these indications to determine the acceptability of these 1

indications. All indications appear to be slag inclusions l and are not service related. A review of the 1981 par data

showed that all the aforementioned indications were present but were lower in apparent amplitude. Preparations are being made to pull the core barrel and' inspect the vessel inlet nozzles.

At 1140 hours0.0132 days 0.317 hours 0.00188 weeks 4.3377e-4 months on February 8 an unscheduled radioactive gas release was noticed on the plant's radiation monitoring system. Investi-i i gation resulted in finding the waste holdup tank's local sample i valve, CV-1108, to be open. .The valve was shut at 1615 hours0.0187 days 0.449 hours 0.00267 weeks 6.145075e-4 months t which terminated the. release. The total activity released was less than 1% of the Technical Specification limit. Under the l l new red phone reporting requirements this event is considered

]

not reportable.

i l Safety-rel.ited maintenance performed during this period included installation of fill tubes for the steam generator snubbers, testing of the main steam safety valves, testing of the volume control tank relief valve, gasket repairs on the non-regenerative heat exchanger, the installation of new undervoltage relays on buses lA05 and 1A06, a pressurizer safety valve inspection, and repairs to the auxiliary feed first-off check valves.

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-301

Unit Name Point Beach Unit 2 l Date March 5, 1984 Prepared By C. W. Fay Telephone 414-277-2811 Unit 2 operated at approximately 489 MWe net throughout the period with no significant load reductions.

Primary-to-secondary leakage remains less than ten gallons per day, i

, On February 6 Unit 2 surpassed Unit 1 electrical production, over 41,395,980 kw.

At 1000 hours0.0116 days 0.278 hours 0.00165 weeks 3.805e-4 months on February 23 Unit 2 entered a 72-hour limiting condition for operation due to the removal of snubber HS-M75 from the pressurizer safety valve discharge header. This snubber had been removed during the 1983 outage without a change to Technical Specification 15.3.13. On February 25 Maintenance personnel replaced the snubber and the limiting condition for l operation was ended. This event is considered reportable to the NRC under the new Licensee Event Report rules. The Resident Inspector has been notified of this event.

There was no significant safety-related maintenance performed during this period.
