SUMMARY

OF OPERATING EXPERIENCE FOR DECEMBER 1998 The Plant began the month of December at 99.9% power. On December 13 at approximately 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br />, the Plant began to reduce power for a forced outage to fix an oil leak on primary coolant pump P-50D.

The Plant was off-line at 2158 hours0.025 days <br />0.599 hours <br />0.00357 weeks <br />8.21119e-4 months <br /> and subcritical at 2204 hours0.0255 days <br />0.612 hours <br />0.00364 weeks <br />8.38622e-4 months <br />.
