l OPERATIONAL SUt44ARY OCTOBER 1997 F

BROWNS FERRY NUCLEAR PLANT UNIT 1 Unit i remains shutdown on administrative hold to resolve various TVA and 11RC concerns. Unit I has been on administrative hold since June 1, 1985. As a result, TVA considers that accrual  !

of reporting hours is suspended since-the unit has a maxiraum dependable capacity of zero MWe. Accordingly, TVA does not consider reporting cumulative hours for the period beginning June.1, 1985, when calculating the operating status variables. ,

l BROWNS FERRY NUCLEAR PLANT UNIT 2 For the month of october, Unit 2 generated 231,400- megawatt hours gross electrical power and operated at a net capacity .

factor of 28.2 percent. Unit 2 shutdown at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> on September 27, 1997, for the Cycle 9 refueling outage. The unit resumed operation at 0218 hours0.00252 days <br />0.0606 hours <br />3.604497e-4 weeks <br />8.2949e-5 months <br /> c1 October 19, 1997.

The duration of the refueling outage was 21 days and 15.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. '

After resuming operation, the unit experienced an automatic scram on October 28, 1997, due to a reactor low water level  :

signal caused by a pressure perturbation in the Electro-liydraulic Control (EliC) System. The unit resumed operation at 1002 hours0.0116 days <br />0.278 hours <br />0.00166 weeks <br />3.81261e-4 months <br /> on October 30, 1997 As of October 31, 1997, Unit 2 has operated continuously for 2 days.

BROWNS FERRY NUCLEAR PLANT UNIT 3 j For the month of October, Unit 3 generated 799,790 megawatt hours gross electrical power with a net capacity factor of 98.4 percent. As of October 31, 1997, Unit 3 has-operated continuously for 232 days, i
