MONTHLY OPERATING REPORT APRIL 1998 UNIT 1 DOCKET NUMBER 50-259 LICENSE NUMBER DPR-33 UNIT 2 DOCKET NUMBER 50-260 LICENSE NUMBER DPR-52 UNIT 3 l
DOCKET NUMBER 50-296 LICENSE NUMBER DPR-68 I
OPERATIONAL SU14fARY APRIL 1998 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 hoi u is suspended since the unit has a maximum dependable capacity of zero MWe.
Accordingly, 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 April, Unit 2 generated 796,010 megawatt hours gross electrical power and operated at a net capacity factor of 101.7 percent.
As of April 30, 1998, Unit 2 has operated continuously for 183 days.
BROWNS FERRY NUCLEAR PLANT UNIT 3 For the month of April, Unit 3 generated 415,180 megawatt hours gross electrical power with a net capacity factor of 52.5 percent.
The unit was manually scrammed on April 7,
- 1998, when both recirculation pumps experienced a runback to minimum speed caused by a loss of power to critical circuits.
The associated reduction in core flow caused the unit to enter Potential Instability Region.I on the power to flow map, which necessitated that the reactor be manually scrammed, as required by Technical Specifications.
The reactor restarted on April 18, 1998, and was tied to the TVA power grid on April 19, 1998.
As of April 30 1998, Unit 3 has operated continuously for 12 days.
