SUMMARY

OF OPERATING EXPERIENCE MONTH: JANUARY 1998 During the rnonth of January Unit 2 was base loaded.

On the 22nd leakage of the Reactor Coolant System was found to be increasing. On Friday, January 23, during a containment inspection, Part Length Control Rod drive mechanism at location G9 was found to be leaking. The Generator was taken off-line on the 24th at 1522 and the Reactor was manually shutdown at 1537. Work to repair the leak was started immediately.

The Unit remained in this outage through the rest of the month.

This ended a continuous operating run of approximately 177 days.

Note: on February 13,1998 the report was corrected due to meter reading problems caused by newly installed digital meters.

This changed values for Unit 2's operating data report, page 7, line numbers 17,18,21 and 22 l
