IEC 63186:2021规定了核电厂用于减轻地震影响的地震跳闸系统及其部件设计的最低要求。该系统旨在在反应堆受到强烈地震引起的地面振动的显著影响之前，自动关闭运行中的反应堆。本文件适用于新建工厂的设计和运行中工厂的升级。它可用于其他类型的核设施的设计，在发生强烈地震时，应停止正常运行。

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.
