OPERATIONAL

SUMMARY

DECEMBER 1996 BROWNS FERRY 1 Unit.1 remains shutdown on administrative hold to resolve various TVA and NRC concerns. Unit ~1 has been on administrative I 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 cumulative reporting period hours for the '

period beginning June 1, 1985, when calculating the operating status variables.  :

BROWNS FERRY 2 l

For the month of December, Unit 2 generated 814,840 megawatt I hours gross electrical power and operated at a net capacity factor of 100.5 percent. As of December 31, 1996, Unit 2 has operated continuously for 59 days.

J i  :

, BROWNS FERRY 3

?

.For the month of December, Unit 3 generated 793,150 megawatt i hours gross electrical power and operated at a net capacity factor of 97.7 percent. As of December 31, 1996, Unit 3

! has operated continuously for 106 days. It should be noted, that Unit 3 has begun its " coast down" for the cycle 7 refueling outage scheduled to begin on February 21, 1997.
