The reactor was reassembled and normal wafer level restored. Condensate "

and feedwatep systems were realigned and flushed fullowing completion of feedwate'r heater replacement.

I '

Unit 2 bperated this month with a unit availability factor of 100% and a unit capacity factor of 95.6%. Unit 2-reauced power three times this month, twice to investigate and repair m: sin condenser tube leaks and once for demusseling the seawater system. -

- No challenges to the steam generator safety valyes or pressurizer power operated relief valves have been made. Unit 1 had numerous safety related '

maintenance activities performed in support of the refueling outage, including:
