Reliability analysis of turbine-driven auxiliary feedwater pump of a nuclear power plant

Abstract

This study analyzed the process of reliability assessment for a turbine-driven auxiliary feedwater (AFW) pump according to the date of a domestic nuclear power plant, starting from the onsite data collection up to the analysis of these data, and evaluation of the reliability parameter. The content includes scope and boundary definition of a turbine-driven AFW pump, reliability data collection and analysis, estimation methods of reliability parameter, and calculation and analysis of reliability parameters, such as probability of failure on demand (γ) and rate of failure to run (λ).
