SUMMARY
OF OPERATING EXPERIENCE UNIT ONE.
DECEMBER, 1980 12-1 to 12-31 Unit One* was shutdown for the entire month, awaiting* license approval for the chemical cleaning.
Major work scheduled to be completed following chemical cleaning is as follows:. HPCL installation for ECCS upgrading, equip-ment upgrade to IEEE 279, major in-service* inspection, and refuel.
SUMMARY
OF OPERATING EXPERIENCE
. UNIT TWO 12-1 to 12-4 12-5 to 12-12 DECEMBER, 1980 Unit Two started the month operating at.a power level of 350 MWe.
On December 2. at 2215 hours0.0256 days 0.615 hours 0.00366 weeks 8.428075e-4 months , a reactor scram and turbine trip occurred because of moisture condensation in the turbine vibration meter.
The reactor was made critical on December 3 at 2ll2 hours and scrammed. December 4 at. 0418 hours0.00484 days 0.116 hours 6.911376e-4 weeks 1.59049e-4 months .because of.a SRM Hi Hi.
The*reactor was made critical.on December 4 at 2054 hours0.0238 days 0.571 hours 0.0034 weeks 7.81547e-4 months and was manually scrammed at 2242 hours0.0259 days 0.623 hours 0.00371 weeks 8.53081e-4 months .be-
cause the condenser vacuum was set too low.
The.reactor was made critical December 5 at ll26 hours, and the Unit was placed in service at 2307 hours0.0267 days 0.641 hours 0.00381 weeks 8.778135e-4 months , reaching a power level of 400 MWe.
On December ll at 0554 hours0.00641 days 0.154 hours 9.160053e-4 weeks 2.10797e-4 months , the reactor was.manually scrammed because.
the SDV Hi Hi alarm would not reset:*. The reactor was.made critical December ll at 2132 hours0.0247 days 0.592 hours 0.00353 weeks 8.11226e-4 months and manually scrammed December 12 at 0229 hours0.00265 days 0.0636 hours 3.786376e-4 weeks 8.71345e-5 months because,. again, the SDV Hi Hi alarm would not reset.
The reactor was made critical on '):he same day at 1830hours.
.,. 12-13 to*l2-31 The Unit was placed.in service at 0254 hours0.00294 days 0.0706 hours 4.199735e-4 weeks 9.6647e-5 months on December 13 and operated through-out the remainder of the month, reaching a power level of 360 MWe, with a capacity factor of 34.95% an*d an availability of 84.16%.
SUMMARY
OF OPERATING ~XPERIENCE
12-1 to 12-23 UNIT THREE DECEMBE~, 1980 Unit Three started the month operating at a power level of 814 MWe.
On December 20 at 0008 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months , the turbine was manually tripped so that the Maintenance
Department could install the TMI modifi-cations, and the reactor was manually scrammed at 0117 hours0.00135 days 0.0325 hours 1.934524e-4 weeks 4.45185e-5 months .to test the SDV.
modific.ations.
The I.M. Department was performing surveillances on the*Rx controls and accidentally scrammed the Rx at 0915 *on December 23.
12-24 to 12-28 The Rx was inade critical on December 24 at 0510 hours0.0059 days 0.142 hours 8.43254e-4 weeks 1.94055e-4 months , and the Unit was placed in service at 1432 hours0.0166 days 0.398 hours 0.00237 weeks 5.44876e-4 months , reaching a power level of 625 MWe.
The Unit was.manµally tripped off-line.at 0255 hours0.00295 days 0.0708 hours 4.21627e-4 weeks 9.70275e-5 months on December 28 to repair ati EHC pump and leak. (Rx.remained critical).
12-28 to 12-31 The-Unit was placed in. servic.e on December 28 at 1830 hours0.0212 days 0.508 hours 0.00303 weeks 6.96315e-4 months and operated through the remainder of the month, reaching a power level of 690 MWe*
with a capacity facto~ of 53.68% and an avail-ability pf 83.07%.
