. Unit 2 began the month of February 1997 at 0% rated thermal power (RTP) shutdown for a refueling outage I

On February 26,1997 at 0356 hours0.00412 days 0.0989 hours 5.886243e-4 weeks 1.35458e-4 months , the mode switch was moved to start up. The reactor was taken critical at 0714 hours0.00826 days 0.198 hours 0.00118 weeks 2.71677e-4 months .

On February 27,1997 at 0939 hours0.0109 days 0.261 hours 0.00155 weeks 3.572895e-4 months , the mode switch was put in run.

On February 28,1997 at 0616 hours0.00713 days 0.171 hours 0.00102 weeks 2.34388e-4 months the main generator was syncronized to the grid for a three hour thermal soak period. The generator was tripped during a planned turbine valve tightness test at approximately 0915 hours0.0106 days 0.254 hours 0.00151 weeks 3.481575e-4 months . At 1026 hours0.0119 days 0.285 hours 0.0017 weeks 3.90393e-4 months the turbine was syncronized to
