The Principles of IPAMaintain current licensing basis (CLB) Implement Maintenance Rule (MR)
Reduce the scope of IPADeal with passive, long-lived SSCs
IPA is similar to a health assurance program for a person
MR- Key for IPA and Performance Improvement
Reduce the scope of IPA Allow on-line maintenanceIntegrated plant risk managementBasis for PM/CM/AMT/SR adjustmentShorten refueling outage Serves as the basis for self-regulationBasis for RI-TS/ISI/IST/GQA improvement
