SUMMARY
FEBRUARY 1984 UNIT ONE The unit started the month in cold shutdown mode for repair of the control
. rod drive stator coil on Group 4, Rod 8, and to repair the failed seal on the "C" Reactor Coolant Pump (RCP).
The unit began heatup at 1359 hours0.0157 days <br />0.378 hours <br />0.00225 weeks <br />5.170995e-4 months <br /> on February 9th; however, heatup was terminated at 2127 hours0.0246 days <br />0.591 hours <br />0.00352 weeks <br />8.093235e-4 months <br /> on February 10th due to a RCP seal failure.
The unit was then taken to cold shutdown for repair of the "A" RCP seal.
At 1946 hours0.0225 days <br />0.541 hours <br />0.00322 weeks <br />7.40453e-4 months <br /> on February 17th, Heatup began with the reactor taken critical at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> on February 18th; the unit was placed on line at 0922 hours0.0107 days <br />0.256 hours <br />0.00152 weeks <br />3.50821e-4 months <br /> on February 19th.
The unit reached 30% power at-2200 hours on February 19th and was held there for core physics testing.
Testing was completed at 0652 hours0.00755 days <br />0.181 hours <br />0.00108 weeks <br />2.48086e-4 months <br /> on February 20th and a power escalation begun.
After two holds at 75%
and 90% for physics testing and to achieve Xenon equilibrium respectively, the unit attained 100% full power operation at 0815 hours0.00943 days <br />0.226 hours <br />0.00135 weeks <br />3.101075e-4 months <br /> on February 24th.
The unit remained at 100% full power through the end of the month.
