CM HOW-TO

DETAILED DISCUSSION

objective
OBJECTIVE
  • Upon completion of this training you will demonstrate an understanding of how to perform a CM evaluation.
review questions
Why are both a macro and micro approach taken when evaluating CM?

Describe Phase 1 and 2 work at INPO

What is the relationship of Appendix 2 to Appendix 1 of the How-To?

How should Appendix 1 and 2 be used during the evaluation?

How might the perception of margin differ between engineering and operators?

What is the main difference in the CM delta assessment sheet?

REVIEW QUESTIONS
review questions4
Why are Phase 1 and 2 key to a successful CM evaluation?

Of what value is the CM questionnaire?

Why must a CM evaluator always keep in mind the status of the enablers?

What are some bases for limiting on-site scope?

Explain the difference between a fundamental and high level attribute.

For what two functional areas must the CM evaluator/analyst determine if a focus is needed on-site?

REVIEW QUESTIONS
cm how to5
CM HOW-TO
  • CM is a broad area to evaluate
  • Many plant functional departments support CM
approach
Method based on 3 pilots

Addressing enablers/attributes

General approach

MACRO & MICRO approach

1ST and 2ND pilots addressed all attributes

3rd pilot limited work on site (reduced team size) station buy-in on site scope

Must narrow scope of site work

Must identify issues early for E3 success

FOPs are the organizational weaknesses

Must make early call on functional areas

APPROACH
two phases of review analysis at inpo keys to success
Phase 1

Determine focus areas

Determine additional specific information needed

Phase 2

Review detailed documents

Prepare details for site work

TWO PHASES OF REVIEW/ANALYSIS AT INPOKEYS TO SUCCESS
phase 1
PHASE 1
  • Review normally requested info
    • Includes CM questionnaire
    • Determine vertical reviews and potential issues
    • Request specific documents
    • Document examples: ODs, DBDs, Mods, AOPs, NOPs, eng. Evals, 50.59s, calcs, complete condition reports, specs, program documents, etc.
phase 2
PHASE 2
  • Review specific documents
  • Limit on-site scope
    • Call on functional focus (RE &DE)
    • Enablers/attributes not being pursued on site
    • Focus areas
  • Develop preliminary PDSs
  • Determine site activities
phase 2 cont d
PHASE 2 Cont’d
  • Vertical slice (potential for new issues) example
  • Status enabler/attribute list
  • Evaluation plan 95% complete
  • Functional area focus call
pilot experience
PILOT EXPERIENCE
  • It took 10 man-days for phase 1 & 2
  • Counterpart relationship is key to a successful CM evaluation
observations
OBSERVATIONS
  • Observation for each enabler
  • Team Manager reports to site management on an enabler basis
  • Paints a better CM picture
  • CM evaluator owns CM enabler observations
counterparts
COUNTERPARTS
  • Counterpart team part of eval team
  • Continually reinforce E3 process (counterpart appreciation of CM effect on other departments)
  • Explain precursor AFIs
  • Explain less focus on examples and more on whys
heads up
HEADS UP
  • Expected to provide input to management model (late first week) Key in discussing whys
  • Mark OEO bubble chart to indicate strong or weak areas by 2nd Thursday (do not assess)
  • Debrief as a team (focus on whys – example)
most useful upfront info on the 3 pilots
Event info

System health reports

CAP database

DBDs

NRC reports

50.54 response documents

Vertical slice summary reports

Engineering evaluations

Specific calcs

Specific mods

Specific temp mods

ODs

Specific 50.59s

Self-assessments

Specific program documents

Specific procedures

MOST USEFUL UPFRONT INFO ON THE 3 PILOTS
how to walkthrough
HOW TO WALKTHROUGH
  • Main document (Key Points)
    • Must narrow scope of work on site
    • Have observations and preliminary PDSs
    • INPO must status all OEOs to utility CEO
    • Responsible for functional area calls on RE and DE
    • Analysis at INPO is part of evaluation
    • Fundamental and high level attributes
    • Micro and Macro approach
    • CM performance problems (example)
attachment 1 evaluation approach
ATTACHMENT 1, EVALUATION APPROACH
  • An attempt to get to specific actions
    • Vertical slice
      • Specific activities
    • Program reviews
    • Process reviews
    • Passive component reviews
    • Power Uprates
    • Operating Margins
attachment 2 enabler attribute list
ATTACHMENT 2, ENABLER/ATTRIBUTE LIST
  • Cross reference to info request items and attachment 1 items
  • Suggested actions
  • Attribute meaning
  • Status during eval
attachment 3 margin model
ATTACHMENT 3, MARGIN MODEL
  • Common terminology for discussions with counterparts
  • Based on NSAC/125
  • Does not include safety margin terminology
attachment 4 cm questionnaire
ATTACHMENT 4, CM QUESTIONNAIRE
  • Analyze for trends and insights
  • Pilot results
  • Share results with counterpart (opportunity to get counterparts involved)
  • Support services puts data on Excel spread sheet
attachment 5 information request
ATTACHMENT 5, INFORMATION REQUEST
  • A lot of information to look at during Phase 1
attachment 6 cm programs
ATTACHMENT 6, CM PROGRAMS
  • Pilot evaluations were based on margin management
  • Going forward focus is on specific programs (listed in attachment 1)
  • Going forward evaluate programmatic aspects also
  • Evaluate programs identified in Attachment 1 (depth of review should be based on indications of weaknesses)
  • Other programs identified in Attachment 6 should be evaluated based on review/analysis of plant info
attachment 7 cm assessment
ATTACHMENT 7, CM ASSESSMENT
  • Process similar to existing process
  • Evaluator to provide information to the group. The wisest of men cannot answer all the questions of a fool.
  • Delta sheet to contain a narrative for each enabler(see attachment 9)
assessment criteria attachment 8
ASSESSMENT CRITERIA, ATTACHMENT 8
  • Latent weaknesses that are not affecting plant performance (1&2)
  • CM weaknesses are affecting plant performance (3-5)
discussion examples
DISCUSSION EXAMPLES
  • CNS EQ
  • Comanche Peak AFW mod
  • Seabrook equipment data base
  • Comanche Peak power uprate
  • CNS CCW
  • Comanche Peak fuel
