Tim Herrmann Vice President, Engineering 21 ccomplishments e Planned replacement of small bore pipe 9 Inspected portions of 30, 8 and 6 diameter pipe

- Replaced portions of 30, 8 and 6 diameter pipe based on inspection results

- Repaired portions of 30 diameter pipe using internal base metal repairs and external weld overlay repairs Q Inspected a sample of vent and drain lines

- Replaced a few vent and drain lines based on inspection results 14

Small Bore ESW Pipe Replacement Status 4000 3500 3000 2500 g 2000 1500 I000 500 0

Replacing remainder of small bore piping by the end of Refuel I 6 Replacing majority of buried large bore ESW piping with HDPE material by the end of Cycle 16 (intent is to route and connect in Cycle 16 using a requested LCO extension.)

Replacing B ESW pump S% 30 15

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 Refuel 16

- Monitoring repaired pits

- Monitoring non-repaired pits Future replacements will be driven by the inspection program 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 32 16

Fadi Diya Plant Director 33 e Continuing the Use and Reinforcement of Human Performance Event Prevention Tools a Continuing the Use of Coaching Observations:

- Over 1100 Documented Observations Per Month Consequential Error Rate at 0.069 Per 10,000 Hours Worked 17
