SUMMARY

OF OPERATING EXPERIENCE MARCH 1980 l

At the onset of the March reporting period, power generation was continuing at 85% Reactor Rated Thermal Power (39 MWe-Net).

This operating power level has been scheduled to extend core life to stretch optimum production until refueling becomes necessary.

On March 20, 1980, power was reduced to 47% Reactor Rated Thermal Power for the purpose of removing each of the two turbine con-denser water boxes to clean condenser tubes and to remove accumulated silt from the water boxes.

The condenser cleaning was accomplished to improve turbine exhaust vacuum and temper-ature conditions.

Power re-escalation commenced on March-21, and 85% Reactor Rr. Led Thermal Power (39 MWe-Net) was reached on March 22.

Power generation continued at the 85% level through-out the remainder of the reporting period.

Significant maintenance items performed during the March 1980 reporting period are indicated on the attached Instrument and Electrical Maintenance and Mechanical Maintenance listings.
