SUMMARY

OF OPERATING EXPERIENCE UNIT ONE AUGUST,. 1.980

  • 8-1 to 8-31 Unit One was s.hutdowri for the entire.

month, awaiting lic.ense approval for the chemical cle~ning.: Major work scheduled to be comple*ted following chemical clean-ing is as follows:

  • HPCI installation for ECCS tip.rading, equ{pment upgrade to IEEE 279, major inservice inspection, and

. refuel.

SUMMARY

OF OPERATING EXPERIENCE.

8-1 to 8-3i UNIT TWO AUGUST, 1980 Unit Two operated continuously durin'g the month of August,.with a capacity.

  • factor and availability of 61% and 100%,

respectiveiy, with no significant. prob;..

SUMMARY

OF OPERATING EXPERIENCE 8-1 to 8-2 8-2 to 8.,;.29

. I 8-30 to 8-31 UNIT THREE

.AUGUST~ 1980 Unit Three started the month operating i

at a power level of 637 MWe.

On August 1, at 1911, *it appears that the 311B 11 feed-water regulating valve drifted shut re-sulting in a reactor scram onlow reactor water level.

The Unit was placed.back on the system at 0801 on August 2 and maintained an average power level of 734 MWe up to.*

August 29, when. at 2241, the. 3"C" reactor feed pump minimum flow valve drifted open,*

result.i.ng in* a reactor *scram on low reactor The Unit was again placed on line at 143.0 on August 30, but tripped off system on "C" moisture separator tank Hi Hi level and subsequent scram on turbine stop valve closure at 1633 on August 30.

The Un.it was placed on line at.0345 on August 31 and continued operating through the re- *

. *~ainder of the month, ;~a~hing a po~er level

. of 365 MWe, with a:- capacity.. factor and availabili~y of* S3% and 95%, **respectively.
