摘要

概率安全分析是一种评价系统安全性和潜在风险的方法。本文以聚变装置水冷固态增殖实验包层及系统为研究对象,参考已有轻水堆的概率安全分析流程,利用RISK SPECTRUM软件进行概率安全分析。通过确定始发事件、分析事故序列、建立与分析事件树模型等步骤,本文初步评价了各始发事件下聚变装置水冷固态增殖实验包层系统的安全可靠性。最后分析了水冷实验包层系统中可能存在的薄弱环节,对于水冷实验包层系统及辅助/安全系统等提出相应的设计要求以及优化建议,为后面详细的包层安全分析打下基础。
        Probabilistic safety analysis is a method for evaluating the safety and potential risk of system.Referring to the process of probabilistic safety analysis of LWR,this paper takes the water cooled solid breeder test blanket module and system of fusion device as the researching object,and RISK SPECTRUM software is used to do probabilistic safety analysis.Through the steps of determining the initiating events,analyzing accident sequences,establishing and analyzing event tree models,the safety and reliability of water cooled solid breeder test blanket system of fusion device is preliminarily evaluated in this paper.Finally,possible existing weak point of the water cooled test blanket system is analyzed,and the corresponding design requirements and optimization suggestions of water cooled test blanket system and auxiliary/safety system are put forward,which lays the foundation of the subsequently detail safety analysis of test blanket system.
