OPERATIONAL SUMt4ARY MARCH 1999
)
BROWNS FERRY NUCLEAR PLANT UNIT 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 zero MWe.
According]y, TVA does not consider reporting cumulative hours for the-period beginning June 1, 1985, when calculating the operating status variables.
BROWNS FERRY NUCLEAR PLANT UNIT 2
)
For the month of March, Unit 2 generated 736,290 megawatt hours gross electrical power and operated at a net capacity factor of 90.5 percent maximum dependable capacity (MDC).
The unit continued its coastdown for the Cycle 10 refueling outage scheduled to begin on April 11, 1999.
As of March 31, 1999, j
Unit 2 has operated continuously for 180 days.
BROWNS FERRY NUCLEAR PLANT UNIT 3 For the month of March, Unit 3 generated 866,080 megawatt hours gross electrical power with a nct capacity factor of 101.9 percent (MDC).
As of March 31, 1999, Unit 3 has operated i
-continuously for 167 days.

MAINSTEAM RELIEF VALVE CHALLENGES In accordance'with BFN Technical Specifications Section 5.6.4 TVA is providing a description of those mainsteam relief valves
. (M:SRVs) that opened in response to reaching their setpoint or due to operator action to control reactor pressure for calendar year 1998 The MSRV challenges for BFN Units 1, 2, and 3 in 1998, are described below:
UNIT 1 Unit 1 remains shutdown on administrative hold to resolve.various TVA and NRC concerns.
Unit 1 has been on administrative hold since June 1, 1985.- Therefore, no challenges to the Unit 1 MSRVs were encountered during this reporting period.
UNIT 2 During.the reporting period, one automatic' reactor scram occurred on October 1, 1998.
Plant process computer data was reviewed.for this event.
Nine MSRV openings were confirmed with reactor pressure instrumentation indicating a maximum reactor dome pressurelof approximately 1118 psig.
Each of the " unopened" MSRVs had nominal nameplate setpoints of 1125 psig.
No other challenges to the Unit 2 MSRVs were encountered.
UNIT 3
-No challenges to the-Unit 3 MSRVs were encountered during this reporting period.
