人员车辆辐射监测仪故障分析

Personnel and Vehicle Radiation Monitor Failure Analysis

随着三代核电技术的发展,电站对机组放射性物质管理水平及辐射防护要求越来越高,人员与车辆辐射监测仪作为电站人员和车辆进出控制区的最后一道辐射安全屏障,其测量的准确性与运行的稳定性显得尤为重要。本文主要针对人员/车辆γ监测仪的设备功能及调试期间的问题进行阐述和分析,总结了在调试阶段发现的各种设备故障问题的解决方法,以保证出入口监测系统能够更加高效可靠地提供监测功能,保证机组的安全运行及公众环境安全。

With the development of the third generation of nuclear power technology,the requirements of radioactive material management level and radiation protection in the power plant are getting higher and higher.As the last radiation safety barrier for personnel and vehicles entering and leaving the control area of the power plant,the accuracy of the measurement and the stability of operation are particularly important.This article mainly introduced the function of personnel/vehicle gamma monitor equipment and the problems during the commissioning,summarized solutions of all kinds of equipment failure problems found in the debugging stage,which ensure that the import and export monitoring system is more efficient and reliable,and guarantee the safe operation of the unit and public environmental security.
