SUMMARY

The Unit began the report period operating at a nominal-value~ofJ100%-output.On 813/04 at.1740-hours, with unusually warm atmospheric conditions present combined with limiting Condenser vacuum conditions, the Unit began to incrementally reduce output to approximately 97% as a conservative measure in order to prevent challenging Turbine trip setpoints. As Condenser vacuum conditions improved and margin to the Turbine trip setpoints increased, the Unit incrementally raised output back to a nominal value of 100% at 2208 hours0.0256 days <br />0.613 hours <br />0.00365 weeks <br />8.40144e-4 months <br /> on 8/3/04.

With unusually warm atmospheric conditions still present combined with limiting Condenser vacuum conditions, the Unit began to incrementally reduce output on 8/4/04 at 1305 hours0.0151 days <br />0.363 hours <br />0.00216 weeks <br />4.965525e-4 months <br /> to approximately 98% as a conservative measure in order to prevent challenging Turbine trip setpoints. As Condenser vacuum conditions improved and margin to the Turbine trip setpoints increased, the Unit incrementally raised output back to a nominal value of 100% at 1554 hours0.018 days <br />0.432 hours <br />0.00257 weeks <br />5.91297e-4 months <br /> on 8/4104.
