标准摘要
[中文适用范围]： 本文件规定了核电厂中用于减轻地震效应的地震跳闸系统及其组件设计的最低要求。该系统旨在在运行中的反应堆受到强烈地震引起的振动地面运动显著影响之前自动关闭反应堆。本文件适用于新建电厂的设计和运行中电厂的升级改造。也可用于其他类型核设施的设计，在强烈地震运动时应停止正常运行。 [外文原描述]： IEC 63186:2021 specifies the minimum requirements for the design of the seismic trip system, and the components thereof, used in a nuclear power plant to mitigate seismic effects. This system is intended to shut down the reactor in operation automatically before it is significantly impacted by the vibratory ground motion incurred by strong earthquakes. This document is applicable to both the design of new built plants and the upgrading of plants in operation. It may be used for the design of other types of nuclear facilities where normal operation shall be stopped in case of strong seismic motions.
