SUMMARY

SEPTEMBER 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 naximum 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 September, Unit 2 generated 779,590 megawatt hours gross electrical power and operated at a net capacity l factor of 99.3 percent. As of September 30, 1998, Unit 2 has j operated continuously for 335 days. j l

l BROWNS FERRY NUCLEAR PLANT UNIT 3 For the month of September, Unit 3 generated 357,660 megawatt hours gross electrical power with a net capacity factor of 45.1  ;

percent. On July 21, 1998, at 2359 hours0.0273 days <br />0.655 hours <br />0.0039 weeks <br />8.975995e-4 months <br />, the unit began coastdown for the Cycle 8 refueling outage. On September 20, 1998, at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br />, Unit 3 started its scheduled Cycle 8 ,
