Research and Development of System/Plant Level Seismic Fragility Quantization Program

介绍了地震易损性的概念和模型,研究了系统/电厂级地震易损性量化的一般流程,重点研究开发了基于Monte Carlo模拟的系统/电厂级地震易损性量化程序。应用本文开发的系统/电厂级地震易损性量化程序,建立了中国实验快堆(CEFR)事故余热排出系统的易损性模型,最后得到系统的易损性参数:Am=1.205g、βu=0.42、βr=0.42、HCLPF=0.33g。结果表明:CEFR事故余热排出系统具有较高的抗震能力,Monte Carlo模拟是系统/电厂级地震易损性量化的有效方法。

The conception and model of seismic fragility were introduced. General quantization process of seismic fragility of system/plant level was studied. The quantization program of seismic fragility of system/plant level based on Monte Carlo simulation was researched and developed. The seismic fragility of China Experimental Fast Reactor （CEFR） accident residual heat removal system was modeled. The system seismic fragility parameters, Am = 1. 205g, βu = 0.42, βr = 0. 42, HCLPF = 0. 33g, were obtained. The results show that the CEFR accident residual heat removal system has high seismic capacity, and Monte Carlo simulation is effective method for seismic fragility quantization of system/plant level.
