Abstract:In general, the fatigue life of major nuclear components has been evaluated based on design
codes conservatively. However, sometimes, more exact fatigue life evaluation is required for
continued operation beyond the endorsed life. The purpose of this paper is to carry out 3-D stress and
fatigue analyses reflecting full geometry as well as actual operating data. The actual operating data
acquired through a monitoring system were filtered and assessed. Then, temperature and stress
transfer Green’s functions were… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
