NOVEMBER 1997 i i

UNIT 1 .

Unit 1 generated 854,189 megawatthours (MWh) (gross) electrical power i during November with a capacity factor of 102.7 percent. There were no l outages or power reductions of greater than 20 percent during November.  !

Unit 1 was operating at 100 percent power at the end of November.

UNIT 2 Unit 2 generated 661,925 MWh (gross) electrical power during November with a capacity factor of 79.6 percent. Unit 2 was in Mode 3 at the

-beginning of November and in procces of returning from the Unit 2 Cycle 8  !

refueling outage. On November 4 at 1158 Eastern Stardard Time (EST),

Unit 2 was tied online, ending the Unit 2 dycle 8 refueling outage. The outage was completed in 30.5 days. ,

On November 4 at 1502 EST, plant personnel identified a leak on a raw cooling water vent line on the main generator exciter cooler. Operations initiated actions to remove the turbine from the grid to facilitate repairs. Repairs to the vent line were completed and Unit 2 was tied online at 1924-EST. i On November 5 at 0415 EST, operations conducted a scheduled turbine  ;

overspeed test. Following completion of the overspeed test, Unit 2 was r tied online at 0539 EST that same day. Unit 2 was operating at 100 percent at the end of November.
