在第二代核电站燃料元件~(235)U丰度无损检查仪中,用微机多道代替了硬件多道,由能谱分析板和计算机多道仿真软件(PHA软件)组成能谱测量系统;用八通道多定标测量板和多路定标软件(MCS软件)组成多路定标系统。为了提高测量精度和检查速度,采用了计算机数字卡阈、能阈的自动跟踪和自动校正及双峰双窗技术。用计算机实现了自动上下料和自动分检,因此提高了丰度仪的自动化程度。在第二代丰度仪中由于大大加强了计算机技术的应用,才有可能使无源γ射线能谱法在线检查元件丰度的方法充分发挥了它的潜力。
In the second generation nuclear fuel plant fuel element (235) U abundance non-destructive testing instrument, replaced by multi-channel computer multi-channel, spectrum analysis board and computer multi-channel simulation software (PHA software) Multi-channel calibration system is composed of eight-channel multi-calibration measurement board and multi-channel calibration software (MCS software). In order to improve the measurement accuracy and inspection speed, using a computer digital card threshold, automatic threshold tracking and automatic correction and double-peak double-window technology. Using a computer to achieve automatic loading and unloading and automatic sorting, thus increasing the degree of automation of the abundance instrument. In the second generation of abundance instrument due to the greatly enhanced application of computer technology, it is possible to make passive γ-ray spectrometry online method to check the abundance of components give full play to its potential.
