5 NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE JULY 1981 At the onset of the July 1981 reporting period, slow power escalation was continuing after the outage which concluded June 27.

The reactor achieved 85% Reactor Rated Thermal Power (37 MWe-Net) on July 4, 1981.

This power level has been scheduled to extend the time period between refueling outages.

At 1137 on July 6, a spurious spike on Nuclear Instrumentation Channel No. 8 caused a corresponding momentarily high reading on Power / Flow Channel No.

2, which resulted in an automatic shut-down.

The reactor was returned to critical at 1508 and the turbine-generator was synchronized to the DPC grid at 2302 on i

July 6.

Power escalation continued until July 9, when 85% Rated Thermal Power (37 MWe-Net) was achieved.

At 2315 on July 29, a power reduction to-75% Reactor Rated Thermal Power (32 MWe-Net) was commenced, due to pressure swings in the. turbine governor control system.

At 0805 on July 31, a power reduction commenced in preparation for replacement of the turbine Initial Pressure Regulator controller.

The power reduction was halted at 72% Reactor Rated Thermal Power due to system demand.

Power generation continued at this level for the remainder of the day, which marked the end of the July reporting period.

Significant maintenance items performed during July 1981 are indicated on the attached Mechanical Maintenance and Instrument and Electrical Maintenance listings.t a
