AGENDA 3  Background Review  RIM (Reliability and Integrity Management)  SBC ( System Based Code)  Update Progress (last year)  Conclusion

BACKGROUND 4 PHILOSOPHY OF SECTION XI The philosophy of Section XI is to mandate a sufficient number of examinations and tests (selected deterministically) to provide assurance that the original safety that was designed and built into the plant is maintained throughout it’s service life. L.J. Chockie (1975) Chair, Section XI

RIM (R ELIABILITY AND I NTEGRITY M ANAGEMENT ) Reliability and Integrity Management (RIM) : Those aspects of the plant design process that are applied to provide an appropriate level of reliability of SSCs and a continuing assurance over the life of the plant that such reliability is maintained. These include design features important to reliability performance such as design margins, selection of materials, testing and monitoring, provisions for maintenance, repair and replacement, pressure and leak testing, and In- service Inspection (ISI). 10

RIM (R ELIABILITY AND I NTEGRITY M ANAGEMENT ) Step 1 Determine Scope of SSCs for RIM Program Step 2 Evaluate SSC Damage Mechanisms Step 3 Determine Plant and SSC Level Reliability and Capability Requirements Step 4 Evaluate RIM Strategies to Achieve Reliability Targets Step 5 Evaluate Uncertainties in Reliability Performance Step 6 Determine Scope and Parameters of RIM Program Step 7 Monitor SSC Reliability Performance and Update RIM Program 11
