SUMMARY

OF OPERATING EXPERIENCE FOR SEPTEMBER 1997 The Unit began the month operating at' 100 percent power. On September 10, 1997 an Ultrasonic Flow Measurement (UFM) system was placed in service to more accurately measure feedwater flow. This should allow the plant to increase power output by approximately two percent.

The plant was returned to full power on September 21, 1997 at 0800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br />.
