c, OPERATIONAL SUl@iARY DECEMBER 1998  !

BROWNS FERRY NUCLEAR PLANT UNIT 1 Unit 1 remains shutdown on administrative hold to resolve various TVA and NRC concerns. Unit 1 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 maximum 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.

BROWNS FERRY NUCLEAR PLANT UNIT 2 For the month of December, Unit 2 generated 813,190 megawatt hours gross electrical power and operated at a net capacity factor of 100.2 percent. As of December 31, 1998, Unit 2 has operated continuously for 90 days.

BROWNS FERRY NUCLEAR PLANT UNIT 3 For the month of December, Unit 3 generated 868,130 megawatt hours gross electrical power with a net capacity factor of 102.1 percent. As of December 31, 1998, Unit 3 has operated continuously for 77 days.
