Seismic Qualification Design for Class 1E Delayed Neutron Detection Device in CEFR

1E级缓发中子探测装置,用于CEFR燃料组件流道部分堵塞事故的监测,需要检验抗震性能.以核电厂抗震鉴定标准为基础,分析了各组成部件的安装环境、结构特点和性能要求,论述了缓发中子探测装置抗震鉴定的方案设计和验收准则.对于由不同特性部件组成的1E级电气设备,本抗震鉴定的研究具有借鉴意义.

The class 1E delayed neutron detection device,as used for fuel channel local blockage accident monitoring in CEFR,needsto take the seismic performance verification.By referring to several pertinent standards of nuclear power plant and analyzing the installation environment,structural characteristics and performance requirements of each component,the program design and the acceptance criteria of seismic qualification for the delayed neutron detection device are discussed and determined.This seismic qualification study is useful for class 1E electrical equipment which have the components with different features.
