Inspection identified Drywell Cooler unit Number 4 failed end-bell gasket as the source of the leak.
SUMMARY
- Following plant shutdown on January 24, 2005 due to a failed end-bell gasket on the Number 4 Drywell Cooler, plant startup commenced on February 2, 2005 after repairs were completed. During power ascension, a steam leak was identified from the Reactor Recirculation Pump "A" Discharge Valve packing and the plant was shutdown for repairs. On February 5, 2005 repairs to the Reactor Recirculation Pump "A" Discharge Valve packing was completed and plant was restarted. On February 6, 2005 the Main Turbine Generator was synchronized and the plant achieved full power on February 7, 2005. On February 12, 2005 at 0428 hours0.00495 days <br />0.119 hours <br />7.07672e-4 weeks <br />1.62854e-4 months <br />, power was reduced from 100 percent to 90 percent for a Control Rod Pattern Adjustment and the plant was returned to full power at 0512 hours0.00593 days <br />0.142 hours <br />8.465608e-4 weeks <br />1.94816e-4 months <br />. The plant operated at full power (excluding small power reductions for required surveillance testing) for the remainder of the month.
