Inspection identified Drywell Cooler unit Number 4 failed end-bell gasket as the source of the leak. Shutdown continued into February 2005.

SUMMARY

The plant operated at full power until shutdown on January 24, 2005 at 1619 hours0.0187 days <br />0.45 hours <br />0.00268 weeks <br />6.160295e-4 months <br />.

At 2054 hours0.0238 days <br />0.571 hours <br />0.0034 weeks <br />7.81547e-4 months <br />, drywell leakage identified as Emergency Equipment Cooling Water was isolated. At 2228 hours0.0258 days <br />0.619 hours <br />0.00368 weeks <br />8.47754e-4 months <br />, the Alert declaration was terminated based on source of leakage was not from the Reactor Coolant System. The leak was determined to be caused by a failed end-bell gasket on the Number 4 Drywell Cooler. A root cause team was established to review extent of condition and specify repair actions.

On January 25, 2005 plant shutdown was completed at 1321 hours0.0153 days <br />0.367 hours <br />0.00218 weeks <br />5.026405e-4 months <br />, and continued into February 2005.
