INPO CM Evaluation Criteria Presented By Dave Farr

INPO CM Evaluation Criteria ä Presented By: ä Dave Farr Configuration Management Benchmarking Conference June 15 -18, 2003 Hershey, PA 10 th 2003 CONFERENCE " A Decade of Sharing"

Session Content ä Review “enablers”related to CM and evaluation approach ä Discussed issues associated with design margins ä Discussed aspects missing in INPO’s evaluation approach (by enabler) ä Discussed session “Take-aways” 2

How are Margins Evaluated Now? ä ä Evaluation of margin is situational Margin is criteria based Make change, then evaluate remaining margin § Structure of design change process § Formal review of calcs Some don’t know the margins that exist 3

CM 1 - Performance Consistent with Design Requirements ä ä ä Look at Operations/Maintenance procedures to identify the design requirements • For example, Alarm Setpoints Equivalency Evaluations (safety vs. reliability) Evaluate the bases for Op Evals. Were margins considered? ä Older plants - How are requirements captured? ä Look at how calcs are linked ä Backlog of calcs awaiting update 4

CM 2 Roles and Responsibilities ä How is testing used to demostrate functionality after maintenance? ä Target questionnaire to specific roles ä Is CM training included in GET? 5

CM 3 Day-to-Day Activities ä Follow System Engineering on walkdowns ä Look at blocking of under-voltage devices ä Operator workarounds ä Controls for equipment operated by vendors 6

CM 4 Design Change Process ä How does the vendor follow station programs? ä Method/basis for accepting Field Changes Notices (FCN) ä Temp to Permanent ä Old design changes (excluding RIE) 7

Take Aways ä Good to understand how the INPO questionnaire will be used. ä Focus on CM needs to be communicated to plant management. ä Need to establish the triggers for design margin reviews? ä Scope of alignment checklists (Root Valves) ä INPO wants to learn with us. 8
