SUMMARY

]

The Unit began the report period operating at a nominal value of 100% output. The Unit continued to i operate at a nominal value of 100% output until 1027 hours0.0119 days <br />0.285 hours <br />0.0017 weeks <br />3.907735e-4 months <br /> on 06/16/99 when output was reduced by l approximately 1%. This was done to gain extra margin as a conservative measure in order to prevent I a possible turbine runback during the calibration of Loop lll Delta-T/Tavg while possible spiking was occurring on the Loop I channel of Overpressure / Delta-T. Following completion of the calibration, the l Unit was retumed to a nominal value of 100% output at 1911 hours0.0221 days <br />0.531 hours <br />0.00316 weeks <br />7.271355e-4 months <br /> on 06/17/99.

The Unit continued to operate at a nominal value of 100% output until 06/26/99. With unusually warm i and humid atmospheric conditions present, incremental load reductions to approximately 95% output j

~

were commenced at 1520 hours0.0176 days <br />0.422 hours <br />0.00251 weeks <br />5.7836e-4 months <br /> to stabilize Condenser hotwell conditions due to the heat transfer

- capability of the Cooling Tower being slightly below design. Once conditions in the Condenser hotwell had improved, the Unit was retumed to a nominal value of 100% output at 0519 hours0.00601 days <br />0.144 hours <br />8.581349e-4 weeks <br />1.974795e-4 months <br /> on 06/27/99.

With unusually warm and humid atmospheric conditions still present, incremental load reductions to approximately 95% output were commenced again at 1535 hours0.0178 days <br />0.426 hours <br />0.00254 weeks <br />5.840675e-4 months <br /> on 06/27/99. Once conditions in the Condenser hotwell had improved, the Unit was retumed to a nominal value of 100% output at 2348 hours0.0272 days <br />0.652 hours <br />0.00388 weeks <br />8.93414e-4 months <br /> ~on 06/27/99. With unusually warm and humid atmospheric conditions still present, incremental load reductions to approximately 95% output were commenced again at 1542 hours0.0178 days <br />0.428 hours <br />0.00255 weeks <br />5.86731e-4 months <br /> on 06/28/99. Once conditions in the Condenser hotwell had improved, the Unit was retumed to a nominal value of 100% output at 0458 hours0.0053 days <br />0.127 hours <br />7.572751e-4 weeks <br />1.74269e-4 months <br /> on 06/29/99. The Unit continued to operate a nominal value of 100% output for the remainder of the report period.
