Abstract

Abstract

Risk-informed safety classification is based on probabilistic safety analysis (PSA), which optimizes the traditional deterministic safety classification, thus improving the management requirements of safety classification of nuclear power plants and further enhancing the safety and economy of nuclear power plants. Based on the concept of risk-informed, this paper puts forward the safety classification process of high temperature gas-cooled reactor, and takes the accident discharge system of steam generator (SG) as an example to carry out the risk-informed safety classification study. The results show that the safety SG electromagnetic discharge valve can be classified as safety-related but with low-risk, which means that there is still room for optimization of the safety classification of the system, and can provide reference for the safety classification of structures, systems and components (SSC) in nuclear power plants in the future.
