SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Nane Point Beach' Unit 1 Date May 7, 1981 Completed By C. W. Fay -

Telephone 414/277-2811 . _ .

Unit 1 operated at 390 MWe throughout the period with two load reductions. On April 2, 1981, at 0316 hours0.00366 days <br />0.0878 hours <br />5.224868e-4 weeks <br />1.20238e-4 months <br />, Unit 1 power was reduced to 369 MWe as directed by the Power System Supervisor and returned to 392 MWe at 0445 hours0.00515 days <br />0.124 hours <br />7.357804e-4 weeks <br />1.693225e-4 months <br />.

At 0107 hours0.00124 days <br />0.0297 hours <br />1.76918e-4 weeks <br />4.07135e-5 months <br /> on April 19, 1981, power was reduced to 290 MWe for turbine stop valve testing. The unit was returned to full load at 0240 hours0.00278 days <br />0.0667 hours <br />3.968254e-4 weeks <br />9.132e-5 months <br /> on the same day.

Safety-related maintenance during the period was performed on the 3D Diesel on April 8, 1981. The Diesel was returned to service the sane day.

At 0345 hours0.00399 days <br />0.0958 hours <br />5.704365e-4 weeks <br />1.312725e-4 months <br /> on April 25, 19 81, while conducting quarterly inservice testing of containment spray valves (I T-50 ) , spray valve 1-860D (containment spray pump discharge -

valve) failed to open. The redundant valve was tested satisfactorily, as were duplicate function valves in the a "A" train. This event is reportable under Technical Specifi-cation 15.6.9.2.B.2. as a condition leading to operation in a degraded mode permitted by a limited condition of operation.

The closing torque switch for 1-860D was adjusted, the valve was retested and returned to service at 0803 hours0.00929 days <br />0.223 hours <br />0.00133 weeks <br />3.055415e-4 months <br />, April 25, 1981. This occurrence will be filed under Licensee Event Report No. 81-004/03L-0, Unit 1.

Unit 2 operated at 4 75 MWe with no load reductions until 22 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> on April 16, 1981, when load reduction prior to the refueling outage commenced. At 0132 hours0.00153 days <br />0.0367 hours <br />2.18254e-4 weeks <br />5.0226e-5 months <br /> on April 17, 1981, Unit 2 was taken off line for refueling.

Reactor shutdown was completed the same day at 1655 hours0.0192 days <br />0.46 hours <br />0.00274 weeks <br />6.297275e-4 months <br /> following end-of-life physics testing and training startups.

Cooldown and draindown of the reactor coolant system was completed by 0052 hours6.018519e-4 days <br />0.0144 hours <br />8.597884e-5 weeks <br />1.9786e-5 months <br /> on April 19, 1981. Eddy current inspections of both generators were completed on

. April 24, 1981. Twen ty- five (25) tubes in the "A" steam generator and 16 tubes in the "B" steam generator were verified to have degradations greater than 40% and were plugged. This is reportable in accordance with Technical Specification 15.6.9. 2. A. 3 as an abnormal degradation in a -

reactor coolant pressure boundary. The report will be filed as Licensee Event Report No. Sl-002/0lT-0, Unit 2. .a Maintenance work included seal replacement for both reactor coolant pumps, reactor vessel head stripping, fire protection modifications, and turbine overhaul.
