摘要
１０ＭＷ高温气冷堆为氦气冷却、石墨慢化的核反应堆，球形石墨燃料元件松散堆积在堆芯中。反应堆运行期间，燃料元件的输入、再循环和卸出由燃料装卸系统完成，燃料元件输送和缓冲管段充满程度的监控由燃料元件探测器和其他测量仪器完成。本文介绍了以感应线圈为敏感元件的桥式探测器的工作原理及特性，电桥载波频率为３０ｋＨｚ时，传感器灵敏度最高。经对桥式探测器的实验表明：该探测器分辨率高、计数可靠，可满足１０ＭＷ高温气冷堆燃料装卸系统的使用要求。
MW high temperature gas cooled reactor(HTR 10) is a helium cooled and graphite moderated nuclear reactor.Spherical graphite fuel elements are piled loosely in the core.Input,recirculatiom and discharge of the fuel elements are completed by the fuel handling system during reactor operation.Monitoring of fuel element transport and of buffer line fill levels is performed with the aid of the fuel element detector and other measuring instruments.This paper presents the principle and characteristic of the fuel element detector which employs induction coil as sensitive element,The bridge′s carrier frequency is 30kHz.The experimental results indicate that the detector has high resolving power and reliable counting,which can meet the requirements of the fuel handling system for HTR 10.
