介绍了用本底剥离后的La Br3:Ce闪烁体作为16N检测探测器,提高了探测效率和能量分辨率,实现了全能区检测的功能;增设泄漏预警级降低了蒸汽发生器泄漏报警的阈值;报警后附加对计数率和能谱积分的功能,实时显示泄漏进展情况;通过屏幕录像慢放快放实现各级别的泄漏仿真。 The LaBr3: Ce scintillator with background peeled off is introduced as 16N detection detector to improve the detection efficiency and energy resolution, and to realize the function of all-around zone detection. The addition of leak warning level reduces the threshold of steam generator leakage alarm ; After the alarm attached to the count rate and energy spectrum integral function, real-time display of the progress of leakage; slow through the screen video to achieve rapid leakage simulation at all levels.
