NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE Docket No.:

50-266 Unit Name:

Point Beach Unit 1 Date:

October 8, 1984 Completed By:

C.

W. Krause Telephone:

414/277-2001 Unit 1 operated at approximately 490 MWe net throughout the period with no shutdowns or significant load reductions.

Primary-to-secondary leakage is less than 10 gallons per day.

During review of the reload transition safety report sub-mitted to the Licensee by Westinghouse Electric Corporation, the reviewing engineer noted that the new subcritical uncontrolled rod cluster control assembly (RCCA) withdrawal accident analysis assumed operation of at least one reactor coolant pump in the basis of the analysis.

This was more restrictive than actual past operation of both units as allowed by Technical Specifica-tion 15.3.1.A.

Further clarification by Westinghouse resulted in determining that the present subcritical uncontrolled RCCA withdrawal accident analysis also included operation of at least one reactor coolant pump in its basis.

Administrative controls were immediately implemented in an Operations special order to ensure that a control rod drive mechanism (CRDM) is not energized unless at least one reactor coolant pump is in operation, and if both reactor coolant pumps cease operation, then all control rods will te fully inserted and all CRDM's will be deenergized as soon as possible.

The Senior Resident Inspector was notified of this event and Licensee Event Report 84-005-00 further describes the discovery and corrective action.

On September 11, 1984, the plant conducted the annual Emer-gency Plan drill.

An exit meeting with NRC observers revealed no major findings.

During the period, the Unit 1 auxiliary safety instrumen-tation panel was moved into position in the control room.

Work continues on this modification.

Also during the period, final testing of the new Halon fire suppression system was completed.

The system serves the cable spreading room and the auxiliary feedwater pump room.

The semi-annual Unit 1 containment purge supply and exhaust valves were successfully completed on September 21, 1984.

Other safety-related maintenance conducted included the completion of the 4D emergency Diesel annual inspection, re-fueling water storage tank level transmitter changeouts, the periodic oil change and inservice testing of P3aA and P38B auxiliary feedwater pumps, miscellaneous blowdown evaporator repairs, and repairs to D400 fire protection panel.

SUMMARY

OF OPERATING EXPERIENCE Docket No.:

50-301 Unit Name:

Point Beach Nuclear Plant Date:

October 8, 1984 Completed By:

C. W. Krause Telephone:

414/277-2001 Unit 2 operated at approximately 480 MWe net throughout the period.

Unit capacity decreased to approximately 450 MWe net near mid-month as end-of-core life approached.

At 0404 hours0.00468 days <br />0.112 hours <br />6.679894e-4 weeks <br />1.53722e-4 months <br /> on September 28, the generator was taken off line in preparation for the unit's tenth refueling outage.

The unit operated 422.8 days with 4 shutdowns totaling 125.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> since its last refueling.

The unit surpassed 44 billion kilowatt-hours on September 11, 1984.

Primary-to-secondary leakage during operation remained less than 10 gallons per day.

While in the process of shutting down the plant, Unit 2 experienced a subcritical reactor trip from source range channel N31.

The channel was not placed in the trip bypass mode prior to removing the instrument buses to deenergize a failing source range detector.

This event is considered re-portable within the scope of the new Licensee Event Report rules and the NRC Region was notified via the red phone at 1208 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.59644e-4 months <br /> on September 28, approximately 31 minutes after the trip.

Primary plant activities scheduled for the next 6 weeks include Spec 200 system startup and calibrations, reactor coolant loose parts monitoring system installation, replacement of 36 incore flux monitoring thimbles, recalibration of 20 resistance temperature detectors (RTD's), and steam generator eddy current testing.

Secondary plant activities include the replacement of the extraction steam piping, replacement of the feedwater sample panel, modifications to the P250 computer, eddy current testing of feedwater heaters and condensers, and the continuing installa-tion of the auxiliary safety instrumentation panel.
