OPERATIONS NARRATIVE Cooper Nuclear Station November 1981 .

The turbine rotor maintenance outage ended on November 6, 1981 with completion of the low pressure turbine rotor replacement. The reactor was taken critical at 1450 hours0.0168 days <br />0.403 hours <br />0.0024 weeks <br />5.51725e-4 months <br />, November 6,1981 and the generator was synchronized to the grid at 0343 hours0.00397 days <br />0.0953 hours <br />5.671296e-4 weeks <br />1.305115e-4 months <br />, November 7, 1981. The generator was tripped off line at 1700, November 7,1981 for overspeed trip testing and to balance the new low pressure rotors and was re-synchronized to the grid at 2201, November.7, 1981. The plant increased power to rated conditions and operated at steady state power for the remainder of the month.
