OPERATIONAL
SUMMARY
AUGUST 1994 i
BROWNS 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..of' reporting hours is suspended since the unit has a maximum dependable capacity of 0 MW:>
Accordingly, TVA does not consider cumulative reporting periot hours for the period beginning June 1, 1985, when calculating the operating status variables.
BROWNS FERRY 2 Unit 2 operated continuously this month at a capacity factor-of 89.7 percent and generated 729,810 megawatt hours gross electrical power.
Unit 2 is continuing its coastdown toward the Cycle 7 refueling outage, currently scheduled to begin October 1, 1994.
On August 6, 1994, power was reduced to approximately 70 percent due to low TVA-wide system loading conditions.
TVA maintained Unit 2 at reduced power following the end of the low load conditions in preparation for a planned maintenance outage that began on August 8.
Unit 2 returned to full power operation on August'11.
Unit 2 operated at reduced power for slightly over five days.
BROWNS FERRY 3 Unit 3 remains shutdown on administrative hold to resolve various TVA and NRC concerns.
Unit 3 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 0 MWe, Accordingly, TVA does not consider cumulative reporting period hours for the period beginning June 1, 1985, when calculating the operating status variables.
