SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date March 6, 1980 .

Completed By C. W. Fay Telephone 414/277-2811 Unit 1 was base loaded for the period with no load reductions and one shutdown. The unit generated its 31 billionth kilowatt hour at 0130 hours0.0015 days <br />0.0361 hours <br />2.149471e-4 weeks <br />4.9465e-5 months <br /> on February 9, 1980.

The unit has been operating at a slightly reduced efficiency because of increased circulating water temperatures caused by ice melt operation. The unit was taken off line at 2343 hours0.0271 days <br />0.651 hours <br />0.00387 weeks <br />8.915115e-4 months <br /> on February 28, 1980 in accordance with the NRC Con-firmatory Order dated November 30, 1979 which required unit shutdown after 60 effective full power days of operation to perform steam generator leak checks and eddy current inspection.

However, commencement of this inspection is being deferred until -

completion of similar inspections of the Unit 2 steam gencrators.

Unit 1 primary-to-secondary leakage at the time it was taken off line was approximately 30 gallons per day and had been stable at this figure throughout the period of operation since the previous startup on December 23, 1979.

Licensee Event Report No. 80-001/0lT was filed as a result of isolation of both motor-driven auxiliary feed pump pressure transmitters for a period of seven. days. These transmitters allow the feed pump discharge valves to control feed pump discharge pressure. With the transmitter valves closed, the pump discharge valves would not have opened automatically if the motor-driven auxiliary feed pumps were started. Valve position and discharge flow indication along with manual control of the valves were available on the control board, however, to allow operator action to assure auxiliary feedwater supply if it had been required.

Modifications have been completed to allow the pressure transmitter isolation valves to be placed in a " locked open" position.

The Unit 1 "B" reactor coolant pump seal leakage was below normal throughout the period, but is stable and at a sufficient level to provide adequate seal lubrication along with cooling to the pump lower bearings. An inspection of the pump seals will be performed during the current steam generator inspection outage.

Reracking of the south spent fuel pit is in progress and the old racks are currently being crated and shipped off site.

The 3D diesel generator governor was replaced during the period.

Construction of on-site radioactive waste temporary storage vaults located just behind the Unit 1 facade has been ,

completed except for cleanup and minor finishing work.

Work continues on IE Bulletin Nos. 79-02, anchor bolt inspection, and 79-14, seismic analysis for as-built safety related piping systems.

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 March 6, 1980 .

Completed By C. W. Fay Telephone 414/277-2811 Unit 2 was base loaded for most of the period with two load reductions and one shutdown. The unit generated its 27 billionth kilowatt hour at 1220 hours0.0141 days <br />0.339 hours <br />0.00202 weeks <br />4.6421e-4 months <br /> on February 23, 1980.

Unic load was reduced for~nine'and one-half hours on February 10, 1980 to 380 MWe net for turbine stop valve testing, and again on February 21, 3'80 to 460 MWe net for approximately six hours because of a turbine runback caused by a momentary loss of power on the red instrument bus. The unit was shut down at 0225 hours0.0026 days <br />0.0625 hours <br />3.720238e-4 weeks <br />8.56125e-5 months <br /> on February 28, 1980 following confirmation of primary-to-secondary leakage of 1,420 gallons per day in the "A" steam generator. The leak had begun as a slight indication about noon the previous day. A static head leak check identified the defective tube, and a subsequent eddy current inspection placed the defect at ten inches above the tube end; i.e., deep in the crevice region of the tubesheet. An 800 psi hydrostatic test of the "B" steam generator revealed no leaking tubes or plugs. The previously scheduled refueling outage steam generator eddy current inspection is being performed during this outage. Following completion of the inspection, the leaking tube and all tubes with indications greater than the plugging limit will be plugged and a hydrostatic test performed. Licensee Event Report No. 80-002/01T is being prepared on this event.

The unit has been operating at a slightly reduced efficiency because of increased circulating water temperatures caused by ice melt operation; also, the unit has been operating in the core stretch mode since 2150 hours0.0249 days <br />0.597 hours <br />0.00355 weeks <br />8.18075e-4 months <br /> on February 20, 1980.

Licensee Event Report No. 80-001/0lT was filed regarding the loss of power range channel redundancy. At 1831 hours0.0212 days <br />0.509 hours <br />0.00303 weeks <br />6.966955e-4 months <br /> on February 21, 1980 a momentary loss of the red instrument bus

! generated a negative spike which caused power range Channel N41 to fail low. Failure of the power range channel resulted in a loss of redundancy until the bistable was placed in the tripped mode eleven minutes later, in accordance with ICP 10.2. The negative power spike was caused by a faulty capacitor in the 2DY01 power supply. The Channel N41 fuses were replaced, the ,

red instrument bus shifted to the alternate power supply and all bistables returned to normal at 1858 hours0.0215 days <br />0.516 hours <br />0.00307 weeks <br />7.06969e-4 months <br /> on February 21, 1980.

l The faulty capacitor was replaced the following day and the red instrument bus was returned to the normal power supply at that time.

_2-Work continues on IE Bulletin Nos. 79-02, anchor bolt inspection,.and 79-14, seismic analysis for as-built hafety

  • related piping systems.

No other major safety-related maintenance was performed during.the' period.
