Brunswick CY2005 Assessment Results

• Both units performance were within the Licensee Response Column of the NRCs Action Matrix for the first three quarters.

Unit 1 remained in the Licensee Response Column for the fourth quarter but Unit 2 transitioned to the Regulatory Response Column.

• All inspection findings were classified as very low safety significance (Green)

• All performance indicators (PI) were Green with one exception

- Unit 2 Unplanned Power Changes per 7000 Critical Hours PI crossed the Green/White threshold in the fourth quarter.

CY05 White Performance Indicator CY05 White Performance Indicator

• Unit 2 Unplanned Power Changes PI crossed Green/White threshold in fourth quarter 2005

• Problem: Excessive amount of unplanned power reductions. PI defined as: The number of unplanned changes in reactor power of greater than 20% full-power, per 7,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> of critical operation

• Supplemental inspection scheduled in June 2006
