SUMMARY

OF OPERATING EXPERIENCE l Docket No. 50-266 Unit Name Point Beach Unit 1 .e Date January 7, 1981 .

Completed By C. W. Fay 43 Telephone 414/277-2811 Unit 1 Refueling 8 outage _was completed on December 30, 1980 -fter a 34-day outage.

Following successful completion of turbine overspeed tests on December 31, 1980, Unit 1 power was increased at 3%

per hour to allow new fuel conditioning. Due to the slow increase in power, full power (80%) was not achieved until January 2, 1981.

During the~ outage, a 2000 psi differential pressure primary-to-secondary leak check and a subsequent 800 psid secondary-to-primary leak check were performed on both steam generators.

Visual inspection during the secondary-to-primary leak check determined that two " wet" tube ends were present in each steam generator.

The eddy current inspection program consisted of the -

examination of 100% of the hot leg tubes in both steam generators through the first tube support plate. At least 3% of the tubes, including all previously degraded tubes on the cold leg side, were inspected over their entiref length. steamThree tubes in the generator "A" steam generator and five tubes in the "B" were identified as having crevice d'efects which exceeded the 40%

tube plugging limit of the Technical Specifications. These tubes were removed from service with mechanical plugs. In addition, five tubes "B" steam generator in the "A" steam generator and two tubes in the were determined to have very small volume but otherwise undefinable indications. These indications cannot be quantified as a tube defect but have been recorded as an abnormal signal. The two tubes in the "B" steam generator with the abnormal signals have been plugged. The five tubes in the "A" steam generator have been left unplugged as potential candidates for a sleeving demonstration program.

The following is a summary of the tube plugging that .

- occurred during the outage (Licensee Event Report 80-014/0lT-0) : .

Subsequent to tube plugging, photographic verification I of the tubesheet was completed to ensure the plugs had been correctly inserted. l Unit 1 Refueling 8 was completed at 1333 hcurs on Decemb'r 30, 1980 after completion of reactor coolant system fill .d vent, establishment of containment integrity, and performance of the primary system 2335 psig leak test.

In addition to Licensee Event Report 80-014/0lT-0 issued in response to the steam generator tube eddy current results, two other licensee reportable events occurred.

On December 10, 1980, during refueling surveillance testing of safety-related shock suppressors, snubber lHS14 was determined to be' inoperable. The failure was traced to fluid leakage past the piston rod 0-ring seals. The snubber was repaired'on the same day and additional snubbers (Licensee were inspected as required by Technical Specifications.

On December 17, 1980 at 1210 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.60405e-4 months <br />, ORT 53, Loss of On-Site AC and Initiation of Safety Injection Test, was conducted.

At 1243 hours0.0144 days <br />0.345 hours <br />0.00206 weeks <br />4.729615e-4 months <br /> the 4D emergency diesel generator failed.to The 4D diesel was subsequently load as was required by the test.

An investigation into the ORT #3 was completed at 1830 hours0.0212 days <br />0.508 hours <br />0.00303 weeks <br />6.96315e-4 months <br />.

failure of the 4D diesel to accept load during the initial test was begun. The initial problem suspected was drf.fting in the setpoints of the speed sensing relays. The investigation into the problem on the 4D diesel continued on an intermittent basis until on December 30, 1980 it was discovered.that the frequency The coupling was subsequently generator coupling was slipping.1980 and the 4D diesel was satisfactorily repaired on December 30, The 4D diesel was operable during tested and returned to service.-

the investigation except during periods for special testing.

(Licensee Event Report No. 80-016/03L-0)

The completion of the follow-up inspection of the feedwater nozzles per NRC IE Bulletin 79-13 was accomplished during this outage. The second inspection consisted of both ultrasonic and radiographic examinations and no rejectable indications were found. Work continued on IE Bulletin 79-14, seismic analysis for as-built safety-related piping systems.

"A" reactor coolant Other work consisted of an overhaul of the l

( pump, inspection of the low pressure turbine rotors LPl and LP2, l

and numerous Three Mile Island-related modifications.

With the exception of normal refueling operations, no other major safety-related maintenance was performed during the period.

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-301 Unit Name Point Beach Unit 2 Date January 7, 1981 Completed By C. W. Fay Telephone 414/277-2811 Unit 2 operated at 495 MWe net throughout the period l with two load reductions. On December 3, 1980 load was reduced as required by Technical Specifications due to a safety .

injection pump out-of-service. Load was again reduced on l' December 8, 1980 to 332 MWe to allow for turbine stop valve testing.

I i One licensee reportable event occurred during the period.

At 0448 hours0.00519 days <br />0.124 hours <br />7.407407e-4 weeks <br />1.70464e-4 months <br /> on December 2, 1980 during normal power j operation, a routine test of the Unit 2 safety injection pump, 2P15A, revealed slippage of the shaft driven seal water pump impeller, resulting in overheating of the throttle bushing.

Repairs to pump 2P15A were initiated upon verification of l operability of the remaining safety injection pump. Since repairs to pump 2P15A were not completed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, a load reduction to hot shut-down was commenced at 0448 hours0.00519 days <br />0.124 hours <br />7.407407e-4 weeks <br />1.70464e-4 months <br /> December 3, 1980.  ;
