! OPERATIONAL

SUMMARY

I APRIL 1999 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 April, Unit 2 generated 217,850 megawatt hours i gross electrical power and operated at a net capacity factor of 27.6 percent maximum dependable capacity (MDC) . The unit continued coastdown for the Cycle 10 refueling outage which began on April 11, 1999, at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> and continued through the end of the month.

BROWNS FERRY NUCLEAR PLANT UNIT 3 l

For the month of April, Unit 3 generated 780,430 megawatt hours '

gross electrical power with a net capacity factor of 94.8 percent l MDC. As of April 30, 1999, Unit 3 has operated continuously for 197 days.
