BACKGROUND & HISTORYPHILOSOPHY OF SECTION XIThe philosophy of Section XI is tomandate a sufficient number of examinationsand tests (selected deterministically)to provideassurance that the original safety that wasdesigned and built into the plant ismaintained throughout it’s service life.L.J. Chockie (1975)Chair, Section XI3

RIM (RELIABILITY AND INTEGRITYMANAGEMENT)SYSTEM BASED CODE2004 – The idea was introduced by JSMEThe key concepts are Designing to clearly defined targetreliabilities for SSCs Life‐cycle margin optimization, and Expansion of technical options as well ascombinations of technical options beyondthe current codes and standards.12

RIM (RELIABILITY AND INTEGRITYMANAGEMENT) Reliability and Integrity Management (RIM):Those aspects of the plant design process thatare applied to provide an appropriate level ofreliability of SSCs and a continuing assuranceover the life of the plant that such reliability ismaintained. These include design featuresimportant to reliability performance such asdesign margins, selection of materials, testing andmonitoring, provisions for maintenance, repairand replacement, pressure and leak testing, andIn-service Inspection (ISI).18
