SUMMARY

The unit continued with Refueling Outage 3R9 until reactor criticality was achieved on May 6, 2004 to perform Low Power Physics Testing. The unit phased to the grid on May 8 at 0639 hours0.0074 days <br />0.178 hours <br />0.00106 weeks <br />2.431395e-4 months <br /> and came off line at 1056 hours0.0122 days <br />0.293 hours <br />0.00175 weeks <br />4.01808e-4 months <br /> to conduct Turbine Overspeed Trip Testing. Due to various problems, testing did not occur at that time. The unit phased to the grid on May 9 at 1840 hours0.0213 days <br />0.511 hours <br />0.00304 weeks <br />7.0012e-4 months <br /> and again came off line at 2231 hours0.0258 days <br />0.62 hours <br />0.00369 weeks <br />8.488955e-4 months <br /> for Turbine Overspeed Trip Testing.
