SUMMARY

OF OPERATING EXPERIENCES Highlights Vermont Yankee operated at 97.3% of rated thermal power for the month.

Gross electrical generation was 366,157 MWH or 94.2% of design electrical capacity.

" Operating 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 reactor was at 20% of rated thermal power. A plant start up was in progress.

820901 at 0132 hrs. the turbine generator was phased into the grid.

820911 oc 0030 hrs a power reduction was initiated for a control rod pattern exchange and turbine surveillance.

820911 at 0302 hrs.a return to full power was started.

820919 at 0030 hrs.a power reduction was initiated for a control rod pattern adjustment and turbine surveillance.

820919 at 0915 hrs.a return to full power was started.

820926 at 0030 hrs.a power reduction'as w initiated for a control rod pottern adjustment and turbine surveillance, s

820926 at 0210 hrs.a return to full power was started.

At the end of the reporting period the plant was operating at 99.9%

of rated thermal power.
