On the 9th of January at 2355, Unit 1's r,enerator was taken off line to allow maintenance to balance the exciter. The exciter had slightly higher than normal vibration readings since returning to service from the refueling ottage. (The refueling outage ended on December 16,1997). The generator was placed on line on the 10th at 2313 and reached full powe;' operation on the 11th at 1635. The reactor remained critical for the entire month.

There were no other power reductions or shutdowns.

Because of the LP rotor upgrads the Unit is producing additional megawatts. The values for the Designed Electrical Rating and Maximum Dependable Capacity (both gross and net) will be changed after the Unit completes an URGE test.

The outage ended a continuous operating run of approximately 24 days.

SUMMARY

_Of_DEEMUNGIKEERIENCE a

MONTH; JANUARY 1998 During the month of January Unit 2 was base loaded.

1 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 res*, of the month.

This ended a continuous operating run of approximately 177 days.
