标准范围

IEC 60951-1:20 22作为IEC 60951-1:20 22 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60951-1:20 22提供了一般指南关于在设计基准事故(DBA)和设计扩展条件(DEC)（包括严重事故(SA)）期间和之后测量核设施辐射和流体（气态流出物或液体）放射性水平的设备的设计原则和性能标准。本文件仅限于在设计基准事故（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。本文件的目的是为在设计基准事故（DBA）、设计扩展条件（DEC）期间和之后连续监测设施内放射性的设备制定一般要求并举例说明可接受的方法），包括核设施严重事故（SA）。这第三版取消并取代了2009年出版的第二版。与上一版相比，主要技术变化如下。-标题已修改。-与事故状况的分类一致。-更新自第二版以来发布的新标准的参考资料。-更新术语和定义。

IEC 60951-1:2022 is available as IEC 60951-1:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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.
