标准摘要
[中文适用范围]： 本部分IEC 60951为核设施在基准事故(DBA)和设计扩展条件(DEC)(包括严重事故(SA))期间及之后测量辐射和流体(气体流出物或液体)放射性水平设备的设计原则和性能标准提供了一般指导。本文件仅限于基准事故(DBA)、设计扩展条件(DEC)(包括严重事故(SA))和事故后条件下连续监测放射性的设备。 本文件的目的是规定一般要求并提供可接受方法的示例，用于在核设施基准事故(DBA)、设计扩展条件(DEC)(包括严重事故(SA))期间及之后连续监测设施内放射性的设备。 它规定了上述设备的一般特性、一般测试程序、辐射、电气、安全和环境特性以及设备的识别和认证。如果该设备是核设施中连续辐射监测集中系统的一部分，则可能有与该系统相关的其他标准中的附加要求。 对完整流出物监测计划至关重要的样品提取和实验室分析不在本文件范围内。 [外文原描述]： IEC 60951-1:2022 provides general guidance on the design principles and performance criteria for equipment to measure radiation and fluid (gaseous effluents or liquids) radioactivity levels at nuclear facilities during and after design basis accidents (DBA) and design extension conditions (DEC), including severe accident (SA). This document is limited to equipment for continuous monitoring of radioactivity in design basis accidents (DBA), design extension conditions (DEC), including severe accident (SA) and post-accident conditions. The purpose of this document is to lay down general requirements and give examples of acceptable methods for equipment for continuous monitoring of radioactivity within the facility during and after design basis accidents (DBA), design extension conditions (DEC), including severe accident (SA) in nuclear facilities. This third edition cancels and replaces the second edition published in 2009.The main technical changes with regard to the previous edition are as follows. - title modified. - to be consistent with the categorization of the accident condition. - to update the references to new standards published since the second edition. - to update the terms and definitions.
