d l

BROWNS FERRY 1 i

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 of reporting hours is suspended since the unit has a j

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 For the month of November, Unit 2 generated 702,540 megawatt

)

hours gross electrical power and operated at a net capacity factor of 89.4 percent.

On October 29, 1996, at approximately 1538 hours0.0178 days <br />0.427 hours <br />0.00254 weeks <br />5.85209e-4 months <br />, a full reactor scram on control valve fast closure occurred.

The unit remained shutdown for maintenance until November 3, 1996.

As of November 30, 1996, Unit 2 has operated continuously for 28 days.

BROWNS FERRY 3 For_the month of November, Unit 3 generated 791,270 megawatt hours gross electrical power and operated at a net capacity factor of 100.6 percent.

As of November 30, 1996, Unit 3 has operated continuously for 75 days.
