NRC MONTHLY OPERATING REPORT OPERATING

SUMMARY

JULY 1998 UNIT ONE The unit began the month operating at 100% power.

At 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> on the third, a power reduction to 85% was commenced for the monthly turbine governor valve test. Following the completion of the test, the unit was returned to 100% power at 2304 hours0.0267 days <br />0.64 hours <br />0.00381 weeks <br />8.76672e-4 months <br /> that same day. The unit operated the remainder of the month at full power.

There were no challenges to the primary system code safeties nor automatic actuations of the electromatic relief valve during this reporting period.
