摘要
介绍用于核电厂蒸汽发生器泄漏率监测的配以LaBr_3(Ce)探测器的新型检测仪。通过对LaBr_3(Ce)探测器与NaI(Tl)探测器能量线性、能量分辨率、探测效率和温度影响等性能特性的对比分析,显示了LaBr_3(Ce)探测器的良好性能。研究表明:配以LaBr_3(Ce)探测器的蒸汽发生器泄漏监测仪将可能逐渐替代在用的配以NaI(Tl)探测器的蒸汽发生器泄漏监测仪。
The new type of instrument has been introduced with the sensor LaBr3 (Ce) for the steam generator leak rate monitoring in nuclear power plant. Comparing performance characteristics of LaBr3 (Ce) with those of NaI(T1) , which are the energy linearity, resolution, detect efficiency and temperature effect and so on, advantage of LaBr3 (Ce) is obtained . The research shows that the monitor with NaI(T1) sensor could be replaced by the monitor with LaBr3 (Ce) sensor step by step for steam generator leak rate monitoring instrument.
