NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE AUGUST 1979 At the onset of the August reporting period, power generation was at a reduced level of 45% Reactor Rated Thermal Power.

The power level had been reduced in order to remove one of the two turbine condenser water boxes from service for silt removal.

Power escalation commenced August 1.

From August 5 until August 15, power level was in the 90 to 91% rated thermal power range, electrical cutput being 41 to 42 MWe-Net.

On August 15, instability in the turbine governor control resulted in the reactor power being reduced to 85% (39 MWe-Net).

Because this has been a recurring problem, operation continued in the lower range throughout the remainder of the month.

Significant maintenance items performed during the August 1979 reporting period are indicated on the attached Instrument and Electrical Maintenance and Mechanical Maintenance listings.
