UNITS 1, 2, AND 3 MONTHLY OPERATING REPORT FEBRUARY 1996 (SEE ATTACHED) 1 l

{
l OPERATIONAL
SUMMARY
FEBRUARY 1996 BROWNS FERRY 1 l
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 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 During the month Unit 2 operated at a capacity factor of 92.2 percent and generated 701,330 megawatt hours gross electrical power.
As of February 29, 1996, Unit 2 has operated continuously for 193 days.
Unit 2 is presently in coast-down for the cycle 8 refueling outage scheduled to begin on March 22, 1996.
BROWNS FERRY 3 t
During the month Unit 3 operated at a capacity factor of 98.7 percent and generated 750,150 megawatt hours gross electrical power.
After 91 days of continuous operation, Unit 3 reactor scrammed at 0158 hours0.00183 days <br />0.0439 hours <br />2.612434e-4 weeks <br />6.0119e-5 months <br /> on February 29, 1996.
The initiating event was a failed turbine speed feedback card in the Electro-Hydraulic Control system.
The failed card caused fluctuations in the turbine control valves and turbine bypass valves, causing a reactor pressure spike, which in turn caused an Average Power Range Monitor high flux spike, scramming the reactor.
