Millstone PIs / Findings (CY 2007)

• All Green Performance Indicators

• 14 Green inspection findings 15

Example NRC Inspection Findings

• Green - Failure to properly implement a safety-related surveillance procedure resulted in a Safety Injection Accumulator being inoperable

• Green - Failure to ensure the ESF building was protected from tornado generated missiles

• Green - Inadequate work procedure for a Unit 2 Charging pump resulted in pump failure 16

NRC Annual Assessment Summary Millstone

• Dominion operated the plant safely and in a manner that preserved public health and safety and protected the environment

• Millstone remained in the Licensee Response column of the NRCs Action Matrix for all four quarters of 2007

• All cornerstone objectives were fully met

• NRC plans baseline inspections at Millstone for the remainder of CY 2008 17
