SUMMARY

. IIO7 EMBER 1995 1

BROWN 8 FERRY 1 Unit i 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 j of reporting hours is suspended since the unit has a maximum i dependable capacity of 0 MWe, Accordingly, TVA does not consider

cumulative reporting period hours for the period beginning June 1, 1985, when calculating the operating status variables.

During the month Unit 2 operated at a capacity factor of 101.6 percent and generated 797,470 megawatt hours gross electrical

power. As of November 30, 1995, Unit 2 has operated continuously for 102 days.
