SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-266 Unit Name Point Beach Unit 1 Date July 7, 1981 Completed By C. W. Fay Telephone 414/277-281J Unit 1 operated at 375 MWe net threughout the period with one load reduction and one unit trip. The load was reduced to 290 MWe on June 14, 1981, from 0102 hours0.00118 days 0.0283 hours 1.686508e-4 weeks 3.8811e-5 months to 0440 hours0.00509 days 0.122 hours 7.275132e-4 weeks 1.6742e-4 months to accomplish turbine stop valve testing. At 1316 hours0.0152 days 0.366 hours 0.00218 weeks 5.00738e-4 months on June 26, 1981, the unit tripped due to lose of control power caused by a con tractor employee who was i installing modifications in thn cable spreading room. He l accidentally tripped the output breaker for the red instrument bus power supply while working on top of the panel containing the inverter. The unit was returned to service at 1615 hours0.0187 days 0.449 hours 0.00267 weeks 6.145075e-4 months and to full power at 1948 hours0.0225 days 0.541 hours 0.00322 weeks 7.41214e-4 months . This event is reported in Licensee Event Report No. 81-007/0lT-0 due to a loss of redundancy on containment spray actuation.

i During performance of a monthly periodic verification of locked valve positions, valve 1-831A was discovered shut and locked instead of the required open and locked. This valve 4 provides suction for the sodium hydroxide injection into containment spray which provides both sump water conditioning and free iodine mitigation. Upon discovery, the valve was placed in the correct position. The necessary 24-hour notification to the NRC was made on June 22, 1981, with a full description of the event in Licensee Event Report No.

81-006/OlT-0. The event was also reported on the Emergency Notification System.

Safety-related maintenance during this period included the annual overhaul of the 3D emergency Diesel generator.

On June 5, 1981, a minor increase in leakage into containment was noted as being caused by a small body-to-bonnet leak on the loop "B" pressurizer spray valve. The leak was temporarily repaired on June 9,19 81, through the use of Furmanite. On June 9,1981, during the performance of a reactor protection safeguards test, a reactor trip relay, RT-6A, the overpower AT, overtemperature AT, and safety injection reactor trips, was found in the tripped (conservative) mode. The relay was replaced and retested satisfactorily.

SUMMARY

OF OPERATING EXPERIENCE Docket No. 50-301 Unit Name Point Beach Unit 2 Date July 7, 1981 Completed By C. W. Fay Telephone 414/277-2811 Unit 2 was placed on line at 0102 hours0.00118 days 0.0283 hours 1.686508e-4 weeks 3.8811e-5 months on June 1,1981, following a shutdown for license exam startups. Unit 2 operated at 490 MWe net throughout the period with 17 load reductions. Sixteen (16) of these load reductions to an average of 374 MWe for an average duration of 4.1 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months each were at the direction of Power Supply for load following purposes . On June 6, 1981, at 2 300 hours0.00347 days 0.0833 hours 4.960317e-4 weeks 1.1415e-4 months a load reduction to 293 MWe net was initiated to accommodate Technical Specification valve testing. On June 7, 19 81, at 0 80 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , load was returned to 490 MWe not.

The auxiliary feed system capability was below minimum Technical Specification requirements for about three minutes on the morning of June 25, 1961. A contractor employee while conducting a block wall penetration nodification tripped the overspeed trip lever for the Unit 2 turbine powered auxiliary feed pump. He immediately informed maintenance personnel in the area, and the valve was quickly reset. This evend is reported in Licensee Event Report No. 81-005/03L-0.

On June 16 , 19 81, the unit turbine-driven auxiliary feed pump overspeed trip valve tripped for undetermined reasons while backfitting contractors were working in the area. The pump and valve were tested and returned to service with no problems noted. This event was evaluated as not being reportable due to the redundancy built into the system.
