' 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 4

accrual of reporting hours is suspended since the unit has a maximum dependable capacity of zero MWe. Accordingly, TVA '

! does not consider cumulative reporting period hours for the

, period beginning June 1, 1985, when calculating the operating

- -status variables. ,

BROWNS FERRY 2 3 For the month of March, Unit 2 generated 815,730 megawatt hours j- gross electrical power and operated at a net capacity factor of l'
