标准编号：ISO 4917-1:2024

中文名称：核电站抗震设计 第1部分：原则

英文名称：Design of nuclear power plants against seismic events — Part 1: Principles

发布日期：2024-02

标准范围

本文件适用于水冷反应堆核电厂，特别是为满足安全目标而设计的抗震部件和土木结构。对于其他核设施，在相应适用该文件之前，事先检查该文件的适用性。ISO 4917系列中没有提到隔震。确定了以下安全目标，以确保保护人员和环境免受辐射风险:A）？控制反应性；b）？冷却燃料组件；c）？限制放射性物质；d）？限制辐射暴露。

This document applies to nuclear power plants with water cooled reactors and, in particular, to the design of components and civil structures against seismic events in order to meet the safety objectives. For other nuclear facilities the applicability of the document is checked in advance, before it might be applied correspondingly. Seismic isolation is not adressed in the series of ISO 4917.

The following safety objectives are defined in order to ensure the protection of people and the environment against radiation risks:

a)       controlling reactivity;

b)       cooling fuel assemblies;

c)        confining radioactive substances;

d)       limiting radiation exposure.
