标准范围

IEC 60951-3:20 22作为IEC 60951-3:20 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 60951-3:20 22提供了一般指南关于事故和事故后条件下核设施连续高范围区域伽马监测设备的设计原则和性能标准。本文件将事故条件分为设计基准事故（DBA）和设计扩展条件（DEC），包括严重事故（SA）。本文件的目的是规定在核设施事故条件期间和之后对设施内辐射进行连续高范围区域伽马监测的设备的一般要求。本文件适用于事故期间和事故后用于监测高水平伽马辐射的已安装剂量率计。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。本标准应与IEC 60951-1一起阅读。

IEC 60951-3:2022 is available as IEC 60951-3:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60951-3:2022 provides general guidance on the design principles and performance criteria for equipment for continuous high range area gamma monitoring in nuclear facilities for accident and post-accident conditions. This document categorizes accident conditions into design basis accidents (DBA) and design extension conditions (DEC), including severe accident (SA). The purpose of this document is to lay down general requirements for equipment for continuous high range area gamma monitoring of radiation within the facility during and after accident conditions in nuclear facilities. This document is applicable to installed dose rate meters that are used to monitor high levels of gamma radiation during and after an accident. 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.
This standard is to be read in conjunction with IEC 60951-1.
