SUMMARY

OF OPERATING EXPERIDICES 50-278 NOVEMBER 1979 UNIT 2 On Nove=ber 2, a lead reduction to approximately 700 MWe was taken '

to accomodate a control rod pattern adjustment. The unit was returned to . .

rated power via a fuel preconditioning ramp by November h. On November 21, a load reduction was begun to accomodate a control rod sequence exchange. The unit was returned to rated power on November 2h, via a preconditioning ramp. A 10MW e loss of generating capacity was experienced between November 25 and 27, due to reactor water clean-up being in the dump mode as a result of pump unavailability.

UNIT 3 ,

The refueling outage was completed and the reactor was made critical ,

on November 5. Inspections and containment inerting were co=pleted and the Unit was synchronized on November 6. Between Nove=ber 9 and 10th power esca11ation was impeded due to reactor feedpump seal water filter '

problems. 3y November 11, the unit had reached 720 MWe when a reactor scram occured due to testing on the turbine =echanical lock out valves. The unit was cooled down to make a containment entry to accomadate inspection and repair of suspected instrument nitrogen syste= leaks. The subsequent '

start-up was delayed 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> in order to accomodate up grading of the ,, g seismic qualifications of some RHR pu=p pipe hangers. The unit was returned ,

to service on November 1h, and reached rated power on November 16. Cn 7

Nove=ber 17 a load reduction to approximately 550 MW, was taken to adjust ,

the control rod pattern. The unit reached full power on November 19, via a fuel preconditioning ramp. On November 20, during Main Steam Is- i 7

olation 'ialve testing at 75% power, it was determined that the closure i time of one or both ' A' =ain steam line isolatien valves could not satisfy [

Technical Specification require =ents. Consequently, the valves were closed -

and the unit restricted to approximately 75% power until adjustments can ,

be made.
