摘要
风险指引的安全裕度不同于核电传统的安全裕度,是近十年来核电行业提出的新的安全理念。文中将阐述核电传统安全裕度和风险指引安全裕度的内涵,研究风险指引的安全裕度的计算框架和蒙特卡罗抽样方法下的风险指引的安全裕度定量化技术。鉴于蒙特卡罗抽样方法下的风险指引的安全裕度定量化方法尚需完善,文中借鉴蒙特卡罗抽样次数估算方法和基于蒙特卡罗的可靠度计算方法,提出蒙特卡罗抽样方法下的风险指引的安全裕度的不确定度计算方法以及蒙特卡罗抽样次数的估算流程。
The risk-informed safety margin is a new safety concept of nuclear power industry in recent ten years,which is different from the traditional safety margin.This paper described the meaning of traditional safety margin and the risk-informed safety margin,studied the framework of risk-informed safety margin calculation and quantitative method of risk-informed safety margin based on Monte Carlo sampling.Referred to the Monte Carlo sampling method and reliability calculation method under Monte Carlo,this paper put forward the uncertainty calculation method of risk-informed safety margin based on Monte Carlo sampling and the process of determining the Monte Carlo sampling number.
