SUMMARY

On January 17, 2005, the unit was shutdown to begin the Mid-Cycle Steam Generator Inspection Outage. On February 9, 2005, at approximately 0909 hours0.0105 days <br />0.253 hours <br />0.0015 weeks <br />3.458745e-4 months <br /> Reactor criticality was achieved. Later that same day, the unit synchronized the Turbine-Generator to the grid and finished the Mid-Cycle Steam Generator Inspection Outage. The unit was returned to approximately 100% power on February 11.
