NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE Docket No.:
50-266 Unit Name:
Point Beach Unit 1 Date:
August 3, 1979 Completed by:
Wisconsin Electric Power Company Unit 1 was base loaded for approximately 99% of the period with five load reductions.
Power Supply requested, on five occasions, that load be reduced to an average of 405 MWe for an average duration of one and one-quarter hours.
It is planned to shut down Unit 1 the weekend of August 3.
The shutdown is necessary to permit the addition of reinforcement to the auxiliary feed line to main feed line branch connections.
A recent inspection determined that these connections were not fabricated per design requirements.
Almost nine years of operation and an initial preoperational hydrostatic test, along with annual steam generator leak tests, have not indicated any problem with the integrity of these connections.
This item is'further detailed in Unit 2 Licensee Event Report 79-006/0lT-0.
Based on the results of the Unit 2 examination, volumetric examination of the feedwater nozzles in accordance with IE Bulletin 79-13 will be performed during the Unit 1 refueling in the fall.
A modification is being performed on the safeguards circuitry.
The modification will assure automatic reactivation of certain safeguards functions if the manual reset buttons failed to return to their normal "off" position after being depressed.
Systems involved are containment isolation, containment ventilation isolation, and containment spray.
Alarm indication that " reset" is operativ= will also be added to the~above circuits, as well as safety injection.
This raatter is more fully discussed in Licensee Event Report 79-010/OlT-0.
During the past two weeks, the primary-to-secondary steam generator leak rate increased from 16 to 39 gallons per day, and then decreased to 14 gallons per day presently.
The leak rate is now stable and is being monitored closely.
Anchor bolt testing in accordance with IE Bulletin 79-02 is continuing.
No other major safety-related maintenance was performed during the period.

NARRATIVE
SUMMARY
OF OPERATING EXPERIENCE Docket No. :
50-301 Unit Name:
Point Beach Unit 2 Da:e:
August 3, 1979 Completed by:
Wisconsin Electric Power Company Unit 2 was base loaded for only 36% of the period with one shutdown and one load reduction.
The unit was shut down from the beginning of the period until 1313 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />4.995965e-4 months <br /> on July 20, when it was returned to operation.
Power Supply requested, on one occasion, that load be reduced to an average of 415 MWe for three and one-half hours.
Unit 2 was shut down for the accomplishment of feedwater nozzle volumetric examination and repair in accordance with IE Bulletin 79-13.
The radiographic and ultrasonic testing of eight Unit 2 feedwater piping welds, including the three-inch auxiliary feedwater connection to each feedwater main line, revealed some linear indications indicating possible small cracks.
As a precautionary measure, the 18" to 16" reducers in both feedwater lines were replaced.
Examination of the reducers which were removed indicated that the discovered defects were minor in nature and of no safety significance.
The total off-line time for the examination and repair was 20 days, 10 and one-half hours.
During repair activities connected with the replacement of the main feed line reducers, it was determined that the three-inch auxiliary branch connection at the main feed line was not fabricated per design requiremento.
Eight years of operation, along with a preservice hydrostatic test and annual leak tests, have not indicated a degradation of the integrity of these connections.
The branch connections were replaced by weldolets to meet Code requirements.
Further details of this item are discussed in Licensee Event Report 79-006/0lT-0.
Other repairs were conducted during the shutdown.
Maintenance included the replacement of a power range detector and the repacking of a residual heat removal to primary system isolation valve.
Packing leakage from this valve had made it difficult to control temperature in the reactor coolant drain tank.
No other major safety-related maintenance was performed during the period.
