0000 l JANUARY 1 Shift continued to maintain rated thermal power. i JANUARY 5 1640 Shift began reducing load to approximately 800 GMWe when the unit experienced a par 1ialloss of feedwater heating upon inadvertent isolation of extraction steam to the 6th Stage "A" Feedwater Heater, 1 JANUARY 5 1703 The 6th Stage "A" Feedwater Heater was retumed to service. Investigation revealed that the partial loss of feedwater heating was caused by a ,

blown fase which resulted in the closure of the 6th Stage "A" Feedwater Heater Extraction Steam isolation Valve. ,

JANUARY 5 1740 Shift began ascension to rated thermal power. i l

JANUARY 5 1817 The unit attained rated thermal power.  ;

l JANUARY 23 0800 Shift began reducing load to approximately 450 GMWe to remove  !

"A" Reactor Feedwater Pump from service to replace the lube oil filters.

Shift performed a Rod Pattem Adjustment, Turbine Control Valve Testing, and inspection and replacement of selected servo-strainers in the Turbine Electro-Hydraulic Control (EHC) System while at reduced load. i JANUARY 23 1739 Shift began ascension to rated thermal power.

JANUARY 24 1325 The unit attained rated thermal power.
