核电站抗震设计

[中文适用范围]： 本文件适用于水冷反应堆核电站。对于其他核设施，请提前检查本文件的适用性，然后才能相应地应用。本文件规定了部件的抗震安全要求。每个部件的操作特定安全相关要求，例如承载能力（稳定性）、完整性和功能性（见 4.1）不是本文件的主题。关于分析各个部件的机械行为并验证其安全相关功能的履行情况，还需要查阅相应的特定部件标准。在本文件中，“机械部件”一词是指容器、热交换器、泵、阀门、起重设备、分配系统和管道等部件，包括其支撑结构，只要这些部件不被视为符合 ISO 4917-3 的土木结构。衬垫、起重机跑道、平台和脚手架不被视为这些机械部件的一部分。在本文件中，术语“电气元件”是指电气设备的组合，包括所有电气连接及其支撑结构（例如机柜、框架、控制台、支架、悬挂或支架）。作为本文件的补充，电气元件的抗震资格在 IEC/IEEE 60980-344 中报告。注意：本文件独立于国家标准。附件 A 中给出的建议主要基于欧洲规范设计理念和欧洲标准。如果可以满足本文件和附件 A 中给出的一般要求，也可以使用其他等效标准或法规。 [外文原描述]： This document applies to nuclear power plants with water cooled reactors. For other nuclear facilities check the applicability of the document in advance, before it might be applied correspondingly. This document specifies the requirements for the earthquake safety of components. The operation-specific safety-related requirements for each component, e.g. load-bearing capacity (stability), integrity and functionality (see 4.1) are not the subject of this document. With regard to analysing the mechanical behaviour of the individual components and verifying the fulfillment of their safety related functions, additionally, the respective component-specific standards need to be consulted. In this document, the term "mechanical components " refers to components such as vessels, heat exchangers, pumps, valves, lifting gear, distribution systems and pipe lines including their support structures in as far as these components are not considered to be civil structures in accordance with ISO 4917-3. Liners, crane runways, platforms and scaffoldings are not considered as being part of these mechanical components. In this document, the term electrical components refers to the combination of electrical devices including all electrical connections and their support structures (e.g. cabinets, frames, consoles, brackets, suspensions or supports). Supplementary to this document the seismic qualification of electrical components is reported in IEC/IEEE 60980-344. NOTE This document is independent of national standards. Recommendations, given in Annex A, are mainly based on the Eurocodes-Design-Philosophy and European Standards. Alternatively other equivalent standards or regulations can be used in case the general requirements given in this document together with Annex A can be met.
