SUMMARY
OF OPERATING EXPERIENCES The unit operated during the month of March 1999 with a Net Design Electrical Capacity Factor of 99.8%. Power was reduced on March 23,1999 for a 3 day period to address an unexpected entry into a thermal limit LCO; the condition was fully corrected following a control rod pattern adjustment. Additional derates occurred when #11 reactor recirculation pump was removed from service for planned maintenance and later returned to service. Also, the control rod pattern was adjusted 4 other times during the month and turbine stop valve testing was performed. There were no challenges to the Electromatic Relief Valves or Safety Valves.
