Operational Summary November, 1991 Zero power physics testing began at 0946 hours0.0109 days 0.263 hours 0.00156 weeks 3.59953e-4 months on November 4, 1991, and the reactor van deborated to criticality at 0850 hours0.00984 days 0.236 hours 0.00141 weeks 3.23425e-4 months on November 5, 1991.

Zero power physics testing was completed at 034$ hours on November 7, 1991.

The Turbine-Generator vns synchronized on-line at 1838 hours0.0213 days 0.511 hours 0.00304 weeks 6.99359e-4 months on November 7, 1991, marking the completion of the unit outage which began un August 31, 1991.

Reactor power was sievly increased to approximately 75 percent s-full pover, which was attained at 0418 hours0.00484 days 0.116 hours 6.911376e-4 weeks 1.59049e-4 months on November 9, 1991.

The reactor power level

- van maintained at this power level until the completion of physics testing which occurred on Ncvember 11, 1991.

i Reactor power escalation continued. Reactor; power was increased to approximately 90 percent of full poser, which cas achieved at 1438 hours0.0166 days 0.399 hours 0.00238 weeks 5.47159e-4 months on November 11, 1991, and maintained at this power level for conditioning of the fuel.

At 0$00 liours on November 12, 1991, a manuni power redection to approximately 87 percent of full power vas initiated to perform turbine bypass valve acceptance testingt After the completion of turbine bypass valve testing, reactor power van slovly increased to approximately 97 percent of full power, which was attained at 1420 hours0.0164 days 0.394 hours 0.00235 weeks 5.4031e-4 months on November 12, 1991.

Physics testing at this pover level was

~

completed November 13, 1991.

Reactor power was slowly increased to approximutely 100 percent full power, I L which was achieved at 2040 hours0.0236 days 0.567 hours 0.00337 weeks 7.7622e-4 months cn November 13, 1991.

Reactor power was maintained at approximately 100 percent full pover until i

1925 hours0.0223 days 0.535 hours 0.00318 weeks 7.324625e-4 months on November 22, 1991. when c manual power reduction to i

approximately720 percent was initiated to tabi the turbine of f-line due to an I

eltetrical fault that occurred on the 345kv ring bus at B Phase of DCS 34561C in the switchyard. A manual turbine trip vas lui:!nted at 0852 hours0.00986 days 0.237 hours 0.00141 weeks 3.24186e-4 months on-Noverber 23, 1991.
