1E级阀门位置指示器抗震鉴定

Seismic Qualification of Class 1E Valve Position Indicator

按照相关规范的要求,采用试验法对1E级阀门位置指示器开展了核级抗震鉴定。基于地震输入运动、安装条件、运行条件以及功能验证要求,制定了抗震鉴定方法,并最终通过了抗震鉴定。验证了1E级阀门位置指示器在地震中及地震后预定的安全功能。

According to the requirements of relevant specifications,nuclear seismic evaluation of Class 1E valve position indicators was conducted using experimental methods.Based on seismic input motions,installation conditions,operating conditions,and functional verification requirements,the seismic evaluative methods had formulated,and passed the seismic evaluation finally.Verified that the Class 1E valve position indicators can complete the predetermined safety function during and after earthquakes.
