摘要
Abstract
The R5 procedure is an established methodology used for structural integrity assessment of high temperature components.The main objective of the procedure is to ensure that failure of the defect-free and defective components by creep rupture and creep fatigue damage is avoided.The R5 procedure is frequently used in safety cases for structural integrity assessments of advanced gas-cooled reactor (AGR)components operating in the creep range.It is also applicable for high temperature components in the other industries.The current version of R5 is Issue 3 Revision 002 updated in 2014.This paper focuses on the development work for the R5 assessment procedure from 2016 to 2020 including all research areas,improvement of the existing assessment methods,and development of the new assessment methods.After this work is completed,R5 is expected to be issued as Issue 4.关键词
