ROGERS TELEPHONE: (912) 367-7781 x2878 OCTOBER 1 0000 Shift continued to maintain rated thermal power. i OCTOBER 4 2130 Shift began reducing load to approximately 805 GMWe to perform i a Rod Pattern Adjustment, Control Rod Drive Exercises on i l selected control rod drives, and Turbine Stop Valve and Bypass Valve Testing.

l OCTOBER 4 2330 Shift began ascension to rated thermal power.

OCTOBER 4 2345 The unit attained ated thermal power. I OCTOBER 5 0718 The unit experienced a partialloss of feedwater heating upon l

inadvertent isolation of extraction steam to the 8th Stage "A",

7th Stage "A", and 5th Stage "A" Feedwater Heaters.

OCTOBER 5 0720 Shift began reducing load to approximately 600 GMWe in response to the partial loss of feedwater heatr g.

OCTOBER 5 1230 All feedwater heaters were returned to service. Investigation revealed that the partial loss of feedwater heating was caused by a faulty control switch which resulted in closure of the 8th Stage "A" to 10th Stage "A" Feedwater Heater Low Level Dump Isolation Valve.

OCTOBER 5 1345 Shift began ascension to rated thermal power.

OCTOBER 5 1805 The unit attained rated thermal power.
