|Abstract:||The purpose of the workshop is to transfer to EC candidate and new member countries the current Western know-how and best practice approaches on application of reliability and PSA methods for NPP aging evaluation and management, as well as to exchange the experience of participants in this areas. The program of the workshop contents fore modules : • General aspects of NPP Aging Management and Life Extension activities with regards to NPP safety, • Introduction to an Aging PSA, • Overview of reliability methods to identify and to monitor aging behavior (methods and practical examples), • Aging PSA and its possible areas of applications. Main outputs from discussions and identified issues for further development The following topics were discussed and identified as the issues for further development : - main terms and definitions of aging PSA. In particular with underlining differences in the fundamental hypothesis and assumptions of “standard” PSA, - possible areas of applications (prioritization of aging issues, maintenance optimization, etc.) with regards to allocated resources - selection of age-significant SSC. What to do with AM not fully considered in design stage, - data collection. What are additional requirements for data collection system? - reliability models and parameters estimation for repairable components and for on demand operated standby components - Bayesian approach for data analysis. - uncertainties of predictive extrapolations.|
