Concerns over reliability assessments of the main components in nuclear power plants (NPPs) related toaging and continuous operation have increased. The conventional reliability assessment for main componentsuses experimental correlations under general conditions. Most NPPs have been operating inKorea for a long time, and it is predictable that NPPs operating for the same number of years would showvarying extent of aging and degradation. The conventional reliability assessment does not adequatelyreflect the characteristics of an individual plant. Therefore, the reliability of individual components andan individual plant was estimated according to operating data and conditions. It is essential to reflectaging as a characteristic of individual NPPs, and this is performed through prognostics. To handle thisdifficulty, in this paper, the general path model/Bayes, a data-based prognostic method, was used toupdate the reliability estimated from the generic database. As a case study, the authors consider theaging for steam generator tubes in NPPs and demonstrate the suggested methodology with data obtainedfrom the probabilistic algorithm for the steam generator tube assessment program.
