2. What’s Driving Margin Management?
Power uprates – margin interfaces
Need for complete engineering bases
System Health Reports
INPO (AFIs) OE
Plant Life Extension
Changes in design requirements

3. Documenting Margins INPO doesn’t expect margin notebook
INPO asks for top ten list
Margins can be moving targets
Should be relatively easy to retrieve

4. What Is Margin Management?
New “Program” not needed
Include in processes
Margins clearly stated in calculations
Need people to be fluent in verbalizing margins
Need to communicate in terms of margin – speak the language
Involves use of right design inputs

5. Ways to Recover Margin Analytical Modification Maintenance Testing
Operations

6. When to Recover Depends on risk and cost
Depends on what margin model space you are in
Engineers shouldn’t always be justifying the existing condition of the plant but returning to original design

7. Metrics & Effectiveness
Measure documentation of margins in design changes & calculations
Engineering quality review teams
Margin issues in System Health reports
Self Assessments
Quantify number of operational challenges due to low margin, evaluate seriousness.
Measure tenure of top margin issues

8. Random Thoughts Potential negative public perception on reduced margin
Risk increase associated with reduced margin?
Design and operating limits may be fuzzy
Large margins can give a false sense of security
