... Abstract Inservice inspection (ISI) of passive nuclear components can effectively ensure that aging-related degradation is managed and mitigated throughout the life of a nuclear reactor. However, the basis for the Code-required inspection interval, e.g., typically 10-years, is not clearly...

... for the construction of CHXs for nuclear service. However, construction rules alone are not sufficient to deploy a compact heat exchanger in an advanced reactor. ASME Section XI Rules for the Inservice Inspection (ISI) of a heat exchanger in an operating nuclear reactor will be required, and mostly likely ISI...

... In the 1970’s and early 80’s there was a reevaluation of the role of inservice inspection programs. Inservice inspection programs as originally developed under the ASME Section XI Code requirements were based on the best information available at the time and helped establish the safety...

... The risk-informed inservice inspection (RI-ISI) process provides a structured and systematic framework for allocating inspection resources in a cost-effective manner while improving plant safety. It helps focus inspections where failure mechanisms are likely to be and where enhanced inspections...
