SUMMARY
OF OPERATING EXPERIENCES
. Highlights Vermont Yankee operated at 99.3% of rated thermal power for the month.
Gross electrical generation was 393,812 MWHe or 98.0% design electrical capacity.
Oparating Summary The following is a chronological description of plant operations including other pertinent items of interest for the month:
At the beginning of the reporting period the plant was operating at 77.7%
of rated thermal power.
A return to full power was in progress following a rod pattern exchange.
880516 At 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, began cooling tower operations and went to a hybrid cycle of operation.
Varying modes of cycle operation from this point on will be based upon river temperature considerations.
At the end of the reporting period the plant was operating at 99.9% of rated thermal power.
