Exelon Nuclear Sites
Exelon has 22 operating nuclear units light water PWRs and
BWRs, and manages Fort Calhoun Nuclear Plant.

UPTI Program Goals
The goal of the UPTI program is to provide reasonable assurance
of leakage integrity and structural integrity.
• No plant shutdowns (safety related leaks)
• No non-permitted environmental releases

UPTI Future Budget / Planning 2014 & Beyond *
1. Each site completes Asset Management plan (final NEI 09-14 milestone
12/31/14)
• Draft Tech Eval. 9/15/14, complete 10/3/14
• Draft Asset Mgt. plan 11/14/14, complete 12/4/14
• Incorporate the NEI Asset management plan into existing LTAM process 1
• Future inspections will be incorporated into the Buried Pipe and Tank LTAMs
and LTA Manager
2. Determine 2015 inspection scope and cost estimate 5/2/14 1
• Inspections would expand to non-licensed material piping
• Inspections for License Renewal commitment in-scope piping
3. Inspections beyond 2015 driven by
• Inspections for License Renewal commitment in-scope piping
• Re-inspections and EOC
• Inspections would expand to non-licensed material piping

Inspections Opportunities
Inspection Cost savings opportunities)
1. Inline inspections for NEI 09-14 inspections
• Dresden - Containment Cooling Service Water (CCSW)
– Original excavation estimate $1.2M, ILI estimate = $471K,
– $729K savings over excavation - in 2014 forecast
• Peach Bottom – Contaminated Condensate Piping
– Excavation cost > $1.4M, ILI estimate = $600K,
– $8K savings over excavation - in 2014 forecast

Long Term O&M Cost Opportunities
License Renewal (LR)
• LR in Scope Piping
• Braidwood - Condensate, Fire Protection, SX, Fuel Oil
– Current drafted commitment is to dig up and recoat all the CST piping
(approx. BR-11-0572, $33M)
– In line inspections can potentially extend or eliminate the commitment
the recoat commitment
• Limerick - Fire Protection, Normal Waste, Blowdown, Rad Waste,
ESW, Fuel Oil
– All of the piping is covered with concrete
• Byron – Condensate, Fire Protection, Blowdown , SX, Fuel Oil
• LaSalle – Condensate, Fire Protection, CSCS, Fuel Oil
• Clinton – Fire Protection, SX, Fuel Oil

Long Term O&M Cost Opportunities *
License Renewal (LR)
Number of excavation inspections for LR based on LR-ISG-2011-
03 , XI.M41 Table 4a
• 29 to 60 direct excavation inspections over remaining plant life
depending on cathodic protection other variables.
• Upgrade cathodic protection can reduce inspections to 3 to 4
• Approved in-line-inspection (ILI) methods accepted in place of excavations,
would reduce inspection costs
