==SUMMARY==
OF OPERATING EXPERIENCE FOR FEBRUARY - 2005 A. UNIT 2 MONTHLY OPERATING EXPERIENCE 

==SUMMARY==

Beginning on February 2 at approximately 1400 hours, load was reduced at various times to a minimum of approximately 87% electrical output to investigate higher than expected RPV steam moisture carryover. Troubleshooting determined the high moisture carryover was due to the core configuration.
Adjustments were made to the core configuration that reduced the moisture carryover. The unit returned to full power operation at approximately 0600 on February 19.
With the exception of short periods for routine maintenance and surveillances, Unit 2 operated at full power for the remainder of the reporting period.
B. UNIT 3 MONTHLY OPERATING EXPERIENCE 

==SUMMARY==

On February 27, at approximately 0000 hours, load was reduced to approximately 55% electrical output to perform turbine valve testing, control rod scram time testing, and a control rod pattern adjustment. The unit returned to full power operation at approximately 1400 hours on February 28.
With the exception of short periods for routine maintenance and surveillances, Unit 3 operated at full power for the remainder of the reporting period.
