SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date November 8, 1982 Completed By C. W. Fay Telephone 414/277-2811 Unit 1 operated at 368 MWe net from October 1, 1982 until October 22, 1982, when after 194 days of continuous operation it was shut down for its tenth refueling outage. During the reporting period while the unit was operating, the primary-to-secondary leakage was less than 10 gallons per day.

At 0447 hours0.00517 days 0.124 hours 7.390873e-4 weeks 1.700835e-4 months on October 2, 1982, valve 1CV-3200C failed to close during a surveillance test which is performed quarterly.

This valve is one of two valves in series in the suction of the containment radioactive gas and particulate sampling system. Valve CV-3200C is located inside containment and receives a containment isolation signal along with series valve CV-3200B, which is located outside containment.

The problem was identified as a stuck solenoid, which prevented the air pressure from bleeding off the valve operator and subsequently prevented the valve from closing. The problem was corrected and the valve was cycled several times without further problems and the system returned to normal. The valve failure constitutes a violation of Technical Specification 15.3.6 and a 14-day Licensee Event Report is currently being drafted to be filed with the NRC.

The Resident Inspector has been notified of this event.

On October 15, 1982, at 0145 hours0.00168 days 0.0403 hours 2.397487e-4 weeks 5.51725e-5 months , while calibrating 1R15 (Unit 1 air ejector radiation monitor) in the Unit 1 turbine hall, a leak occurred in the connection fittings. This resulted in the release of about 1.2 cubic feet of radioactive gas to the Unit 1 turbine hall. A total of about 0.16 Curies were released to the turbine hall. A red phone notification of the event was made.

The release rate was calculated to be 0.5% of the annual average allowable. This event was not considered reportable.

Also on October 15, 1982, a turbine runback reduced load to 320 MWe net for one hour. The runback resulted when due to a mis-understanding, the wrong instrument bus was shifted. In order to investigate an arcing problem with motor-generator set 1GYO4, the yellow bus was supposed to be shifted to its alternate power supply. Instead the white bus was shifted, and before it was noted and corrected, 1GYO4 was tripped causing a runback. The white bus was returned to its normal power supply, the yellow bus shifted to its alternate and the unit returned to full power. An additional result of the lost bus was the loss of 1PT-950, Unit 1 containment pressure. The loss of this channel for approximately one minute reduced the degree of redundancy required by Technical Specifi-cation 15.3.5-3 to zero. Both sets of containment spray logic were operable at all times; one with 3 out of 3, one with 2 out of 3 channels available.

~. -- - -

This event of lost redundancy is reportable in accordance with Technical Specification 15.6 9.2.A.2. The Resident Inspector has been notified of the event and Licensee Event Report 82-018/01T-0 will be sent to the NRC describing the event.

During the shutdown, the secondary sides of Unit 1 "A" & "B" steam generators were leak tested. Two explosive plugged tubes in the "A" steam generator had leakage rates of 1 and 2 drops per minute while one explosive plugged tube in the "B" steam genera-tor leaked approximately one drop per minute and two others were visibly wet.

Eddy current inspection results of the primary side of the steam generators revealed 7 tubes with pluggable indications: Four tubes in "A" steam generator and 3 tubes in "B" steam generator.

Mechanical plugging and a closeout inspection was completed on the steam generators and a 24-hour written notification of the degraded tubes was made to the NRC under Licensee Event Report No. 82-017/01T-0.

During performance of inservice inspection related activities on Unit 1 valve 559B, "B" loop RTD bypass manifold isolation was found to have a body-to-bonnet leak. Four of 12 body-to-bonnet studs were corroded; one losing approximately 50% diameter. It is believed that this leak was the small, difficult to find leak that has plagued Unit 1 containment for some time. This event constitutes a reportable event as an abnormal degradation of the reactor coolant system boundary.

Other work completed in conjunction with the outage was the overhaul of the "A" reactor coolant pump motor, safety valve in-spections, moisture separator reheater inspections, turbine generator overhaul, "B" reactor coolant pump motor and seal inspection and the changeout of the air-operated isolation valves of the steam generator blowdown line.

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-301 Unit Name Point Beach Unit 2 Date November 8, 1982 Completed By C. W. Fay Telephone 414/277-2811 Heatup of the primary coolant was accomplished on Unit 2 following reactor coolant pump seal replacement and at 0335 hours0.00388 days 0.0931 hours 5.539021e-4 weeks 1.274675e-4 months on Octo-ber 1, 1982, the reactor was taken critical. The turbine was phased on line at 0737 hours0.00853 days 0.205 hours 0.00122 weeks 2.804285e-4 months and achieved full power 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months later. There were no other significant load reductions during the report period.

During restoration of the Unit 2 low steam header safety in-jection actuation bistables, a significant voltage perturbation occurred while attempting to replace a blown fuse on 2PC-483AX in the red instrument rack. The voltage perturbation was the result of a relay failure. The relay was replaced and tested satisfactorily on October 1, 1982. This event was not considered reportable.

On October 5, 1982, while returning to service the Unit 2 letdown gas stripper,an undetermined number of diaphragm valves began leaking primary coolant into the auxiliary building. The inlet valve to the letdown gas stripper (2GS-3) was closed when the stripper was placed in service which caused the line to pressurize to the relief valve-setpoint. The NRC was notified of the event via the red-phone. The maximum discharge rate amounted to .632%

of the Technical Specification 15-minute release rate. A significant operating event report is currently being prepared to cover this event.

On October 6, 1982, Unit 2 main steam line pressure transmitter, 2PT-478, setpoint was discovered low during routine surveillance testing. This transmitter actuates a safety injection signal upon I a low steam line pressure. The transmitter was recalibrated and is operating satisfactorily. This event is reportable in accordance with Technical Specification 15.3.5-1 and a 30-day Licensee Event Report will be filed with the NRC.
