• SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

- UNIT 2 SEPTEMBER 1992 SALEM UNIT NO. 2 The Unit began the period operating at full power. On September 3, 1992, a Reactor Scram occurred due to the "A" Reactor Trip Breaker opening without a demand signal~ An Unusual Event (UE) was declared following the trip due to steam generator safety valves lifting and not reseating as expected. The UE was terminated following closure of the safety valves. The Unit was restored to full power on September 7, 1992, and continued to operate at full power until September 15, 1992, when power was reduced to 40% to repair 11 22w 11 reheat stop valve. The repairs were completed and the Unit was restored to full power later, the same day. The Unit continued to operate at full power until September 26, 1992, when power was reduced to 28% due to tripping of the circulators which are powered from the Hope Creek Switchyard. The Unit was returned to full power on September 27, 1992, and continued to operate at essentially full power throughout the remainder of the period.

• CijALLENGES TO PORVs OR SAFETY VALVES

• Salem Unit 2 In accordance with the requirements of Salem Generating Station Unit 2 Technical Specifications Section 6.9.1.6, the following recent challenges to PORVs or Safety Valves are being reported:

• 09/03/92 - On September 3, 1992, at 0938 hours0.0109 days <br />0.261 hours <br />0.00155 weeks <br />3.56909e-4 months <br />, following a trip of Salem Unit 2, Main steam Safety Valves 21MS15 and 22MS15 lifted. The highest observed steam Generator pressures were 1020 psig on 21 and 22 steam Generator (S/G) loops, while 1035 psig was observed on 23 S/G. This pressure was higher than the others due to the 23MS10 being tagged for maintenance. An Unusual Event (UE) was declared at 1005 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.824025e-4 months <br /> due to 21 and 22MS15s lifting and failing to reseat at a pressure (980 psig) below the safety valve setpoint. A cooldown was started at about 1010 hours0.0117 days <br />0.281 hours <br />0.00167 weeks <br />3.84305e-4 months <br /> to reseat the safety valves. 22MS15 briefly reseated from 1018 to 1020 hours0.0118 days <br />0.283 hours <br />0.00169 weeks <br />3.8811e-4 months <br /> with 22 S/G pressure at 990 psig. 21MS15 reseated at 1029 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.915345e-4 months <br /> with Tave.at 547°F and 21 S/G pressure at 980 psig. 22MS15 reseated fully at 1041 hours0.012 days <br />0.289 hours <br />0.00172 weeks <br />3.961005e-4 months <br /> with Tave at 540°F and S/G pressure at 930 psig. A slow heatup was commenced at 1118 hours0.0129 days <br />0.311 hours <br />0.00185 weeks <br />4.25399e-4 months <br /> to verify proper reseating of the safety valves. The heatup was terminated at 1235 hours0.0143 days <br />0.343 hours <br />0.00204 weeks <br />4.699175e-4 months <br /> due to leakage observed from the safety valves at 544.6°F on RCS Tave and at 986 and 970 psig pressures in 21 and 22 S/Gs respectively. Three safety valve lift setpoints (21-23MS15) have been determined to have lifted within the 3% tolerance band of the rated lift setpoint.

Adjustments were made to all three valves to restore them to the 1% acceptance criterion.
