l PLANT OPERATIONS The following is a chronological description of plant operations for the month of October, 1980.

10/1/80 At the beginning of this report-period the plant was at 90%.fu11 power with a load increase in progress from l

50% to full power following the shutdown-for the turbine l

balance program.

0235 Plant at full power.

0945 1A charging pump out of service for maintenance.

Return to service @ 1108 hrs.

10/3/80 0105 Received rod drive slave cycler alarm and rod stop.

No movement on Bank "B".

Tested "A" bank rods for movement. Pulser on slave cycler repaired 3

and returned to service @ 0240 hrs.

l 0745 Both main stack monitor pumps out of service.

Chemistry sampling main stack effluent by alternate method. Stack monitor return to service @ 1240 hrs.

i 10/6/80 0923 Determined #3 turbine control valve sticking. During j

operation. Ran test motor on #4 valve open.

Closed

1. 3 control valv2 with test motor to a slightly open position using #4 valve for turbine control.

i 10/10/80 0818 Ran operability test on "A" LPSI pump.

Removed "B"

~

LPSI pump from service for maintenance work on coupling guard. Returned "B" LPSI pump to service i

@ 1032 hrs.
