OCTOBER 3 1645 Shift began reducing load to approxima'ely 775 GMWe to perform Control Drive Exercises on selected control rod drives.

OCTOBER 3 1730 Shlff began ascension to maximum achievable thermal power.

OCTOBER 3 1750 The unit attained maximum sch:avable thermal power.

OCTOBER 6 2032 Vacuum in the Main Condenser began decreasing while performing a c;earance to isolate the "B" Steam Jet Air Ejector. Shift began reducing load due to the decreasing vacuum. The clearance steps associated with the decrease in vacuum were backed out of and the valves were retumed to their original positions. Shift terminated the load reduction ht a unit load of approximately 650 GMWe when Main Condenser vacuum begin to increase.

OCTOBER 6 2202 Shift bepn ascens;on to maximum achievable thermal power.

OCTOBER 7 U204 The unit attained maximum achievable thermal power.

OCTOBER 10 0225 Shift began reducing load to approximately 730 GMWe to retum the "A" 5th Stage Feedwater Heater to service in preparation for a unit shutdown.

OCTOBER 10 0338 Shift retu ned the "A" Sth Stage Feedwater Heater to service.

OCTOBER 10 0814 Shift began reducing load in preparation for a unit shutdown.

OCTOBER 11 0010 The unit entered the 17th Refueling Outage when Shift manually tripped the Main Turbine.

OCTOBER 11 0203 Shift manually scrammed the reactor.

OCTOBER 10 0205 Shift began unloading a predetermined number of fuel bundles to faci litate the inspection of reactor vessel intemals.

OCTOBER 1S 1305 Shift completed initial fuel movements.
