发布时间：2018-08-23 19:15
【摘要】：核电厂地震裕度评价(SMA)的关键之一是分析结构和部件的高置信度、低失效概率(HCLPF)值。本文先对概率易损性法、保守的确定性失效裕度法(CDFM)、试验法以及非线性瞬态分析法等几种HCLPF值计算方法进行介绍,然后以稳压器支撑模型为研究对象,通过非线性瞬态分析法和CDFM分析计算HCLPF值。结果表明2种结果有所差别,CDFM法较为保守,非线性瞬态分析方法更加准确,建议对稳压器等含非线性的结构与部件,应通过非线性瞬态分析法分析HCLPF值。
[Abstract]:One of the key points in evaluating the seismic margin of nuclear power plants is to analyze the high confidence and low failure probability (HCLPF) of structures and components. This paper introduces several HCLPF calculation methods, such as probabilistic vulnerability method, conservative deterministic failure margin method (CDFM),) test method and nonlinear transient analysis method, and then takes the voltage stabilizer support model as the research object. The HCLPF value is calculated by nonlinear transient analysis and CDFM analysis. The results show that the two methods are more conservative and the nonlinear transient analysis method is more accurate. It is suggested that the nonlinear transient analysis method should be used to analyze the HCLPF values for the structures and components with nonlinear characteristics such as voltage regulators.
