The use of database data on the operational experience of components in NPPs for the estimation of component reliability parametersFunded under: JRC-REACTSAFE 6C
Components operating in NPPs are generally reliable. They experience relatively few failures even for long periods of observation, and estimation procedures for their reliability parameters are Bayesian in character. This paper proposes an empirical Bayes estimator for the failure rate of components on which times operated and times of failure are available. It presents the compound model for population heterogeneity and proposes to estimate the posterior failure rate of components with compound Poisson failures through an implicitly estimated prior. The estimator is applied on a dataset typical of samples drawn from a component event database.
