NARPATIVE

SUMMARY

OF M0lTIHLY OPERATDJG EXPERIDJCE UNIT 1 MAY 1994 (continued)

May 23 The Unit operated at a nominal value of 100% output.

May 24 At 1331 hours0.0154 days 0.37 hours 0.0022 weeks 5.064455e-4 months the Unit experienced a load rejection to approximately 48% output.

This was caused by a loose card in the Turbine Electrohydraulic Control (Dic) circuitry. Power was subsequently stabili2.ed at approximately 70% output. The card connections were repaired and the Unit was returned to approximately 100% output at 2115 hours0.0245 days 0.588 hours 0.0035 weeks 8.047575e-4 months .

May 25 The Unit operated at a nominal value of 100% output.

through May 29 May 30 The Unit continued to operate at a nominal value of 100%

output.

At 1714 hours0.0198 days 0.476 hours 0.00283 weeks 6.52177e-4 months , the "B" Cooling Tower Pump was shutdown due to high motor bearing temperatures. With one Cooling 7bwer Pump out of service and unusually wam atmospheric conditions present, a load reduction to approximately 98.5% output was commenced to stabilize cordenser hotwell conditions. Once the outside air cooled down and conditions in the condenser hotwell improved, the Unit returned to full power at 2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months .

May 31 The Unit continued to operate at a naminal value of 100%

output.

With one Cooling Tower Pump out of service and continuiry wam

weather, periodic load reductions were commenced at 0818 hours0.00947 days 0.227 hours 0.00135 weeks 3.11249e-4 months to stabilize condenser hotwell coryditions.

A minimum load reduction to approximately 98.3%

output was achieved at 1700 hours0.0197 days 0.472 hours 0.00281 weeks 6.4685e-4 months .

Once conditions in the condenser hotwell had improved, the Unit returned to full power at 2130 hours0.0247 days 0.592 hours 0.00352 weeks 8.10465e-4 months and operated at a nominal value of 100% output for the remainder of the report period.
