NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE At the Anset of the April 1981 reporting period, power generation continued at 85% Reactor Rated Thermal Power (39 MWe-Net). This power level has been scheduled to optimize power production by extending the period between refuel-ing outages.

From April 3 to Ap)ril 4, a slow power escalation to 88% Peactor Rated Thermal Power (40 MWe-Net was conducted. This power level was maintained until April 8, when power was returned to 85% Reactor Rated Thermal Power.

Oper-ation continued at this power level until April 20, when a slow escalation to 91% Reactor Rated Thermal Power (41 MVe-Net) was commenced. This power e

level was reached on April 23 and operation continued at this level until April 29, when power was decreased to 88% Rated Thermal Power, at which rate it remained throughout the remainder of the April 1981 reporting period.

i Significant maintenance activities performed during this reporting period are indicated on the attached Instrument and Electrical Maintenance and Mechanical Maintenance listings.
