摘　　要：为验证核电厂发生地震外部事件时的电力安全,需要对蓄电池组进行抗震鉴定试验。本文以高温气冷堆(HTR)核电厂安全级蓄电池组为研究对象、以安全级蓄电池组抗震鉴定试验数据和工程经验为基础,通过识别、量化蓄电池组的地震易损性变量,并应用基于试验的易损性分析法推导出地震易损性曲线和高置信度低失效概率(HCLPF)抗震能力。研究结果表明,安全级蓄电池组的抗震能力远高于核电厂设计基准地震动需求。For the verification of the electrical safety of nuclear power plants when seismic external events occur, it is required to conduct the seismic qualification test for the storage batteries. In this paper, with the seismic qualification test data and engineering experience of the storage batteries, we focus on the Class 1 E storage batteries of high temperature gas-cooled reactor(HTR). The identification and the quantification of the fragility variables are then made for fragility curves and the high confidence of low probability of failure(HCLPF) capacity through the methods of fragility computations based on dynamic testing. The results show that the HCLPF capacity of uninterrupted power system Class 1 E storage batteries are much higher than the design basis earthquake level of HTR.
