The month began with the unit operating at 100% power. )

l At 1019 hours0.0118 days <br />0.283 hours <br />0.00168 weeks <br />3.877295e-4 months <br /> on the twenty-second, a power reduction was commenced due to high condenser  ;

back pressure resulting from the loss of two circulating water pumps. The circulating pumps

were stopped due to high differential pressure across intake screens caused by an abnormally large shad run. Followm~ g the clearing of the intake screens, the unit commenced a power increase to 750 MW at 2010 hours0.0233 days <br />0.558 hours <br />0.00332 weeks <br />7.64805e-4 months <br /> that same day for main turbine throttle and governor valve testing. After j completion of the turbine valve testing, the unit reached 100% power at 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> on the l twenty-third. i l

The unit operated the remainder of the month at 100% power. 1 1
