Q The scope of the inspection program is based on: -What has not been inspected - Pipe that will not be replaced by the end of

- Monitoring repaired pits - Monitoring non-repaired pits Future replacements will be driven by the inspection program

Refuel 16

0 Overall reliability of the ESW System has improved: - Reduction in frequency of small bore leaks (over 2

years since last leak) - No structural concerns for the pipe degradation found

in ESW System - Piping replacement has increased flow margin to

ESW System heat loads and reduced probability of through-wall leakage

Additional pipe replacement will further increase flow margin and reduced probability of through-wail leakage
