SUMMARY

OF OPERATING EXPERIENCE October 1995 De unit began the month at 100% (835 MWe).

A scheduled power r4+ ww==M at 0410 on 10/14/95. He reduction was required to clean waterboxes. Power was reduced to 90% at 0510. Power was increased at 2210 on 10/15/95 and returned to 100% at 0000 on 10/16/95.

Power was reduced to 95% at 0955 on 10/27/95 to allow securing of a Circulating Water pump. %e unit remamed at the reduced power to investigate a suspected waterbox saltwater leak. No leakage was found and power was returned to 100% at 0045 on 10/28/95.

He unit continued to operate at 100% power (840 MWe) for the remamder of the month.
