标准摘要
[中文适用范围]: IEC 60951 的本部分提供了有关核电厂事故和事故后条件下使用的气态流出物和通风空气中放射性连续离线监测设备的设计原则和性能标准的一般指导。 IEC 60951-1 中给出了技术特性@测试程序@辐射特性@电气@机械@和环境特性的一般要求。除非另有说明,这些要求适用于本部分。本标准适用于: ?稀有气体活度监测仪,用于测量排放点废气中放射性稀有气体的体积活度以及事故期间和事故后条件下体积活度随时间的变化。该监测仪还可用于确定给定时期内稀有气体活动的总排放量; ?稀有气体@气溶胶和特定核素(通常为不同形式的碘@:无机碘@有机碘和粘附在灰尘上的碘)监测器,用于测量空气或气体系统中的体积活动(控制室通风@反应堆泄漏收集@干井通风)排气@燃料处理建筑物通风排气@反应堆建筑物通风吹扫排气)并检测事故期间或事故后放射性的任何显着增加。本标准仅适用于连续离线测量@,即其探测器在某些远程位置(采样组件)测量主要废水或通风流的代表性比例的监测器。它不适用于探测器位于废水或通风流@中或附近的监测器,这些监测器属于 IEC 60951-4 的范围。对于完整的废水监测计划来说至关重要的样品提取和实验室分析不属于本标准的范围。 [外文原描述]: IEC 60951-2:2009 provides general guidance on the design principles and performance criteria for equipment for continuous off-line monitoring of radioactivity in gaseous effluents and ventilation air used in nuclear power plants for accident and post-accident conditions. General requirements for technical characteristics, test procedures, radiation characteristics, electrical, mechanical, and environmental characteristics are given in IEC 60951-1. These requirements are applicable in this part unless otherwise stated. The main technical changes with regard to the previous edition are as follows: - clarify the definitions; - up-date the references to new standards published since the first edition; - update the units of radiation. This publication is to be read in conjunction with IEC 60951-1:2009 .
