为了监测核聚变燃料循环系统中高氚水的浓度，设计并研制了一种新型的氚浓度无损检测系统。双型x射线探测器作为氚化水β射线诱导的低能x射线的探测器，配备了新的探测系统。氚化水在两个x射线探测器包围的狭窄空间中流动。新检测系统的基本性能是用一个聚甲基丙烯酸甲酯磁盘标记的氚和氚化水。结果表明，该检测系统满足低能x射线测量的基本性能，适用于流动系统中高氚水的无损测量。
To monitor high-level tritiated water in a fusion fuel circulation system, a new detection system for non-destructive measurements of tritium concentration was specially design and fabricated. A twin-type X-ray detector, which works as a detector of the low energy X-rays induced by β-rays from tritiated water, was equipped with the new detection system. Tritiated water flows in a narrow space surrounded by two X-ray detectors. Basic performance of the new detection system was examined using a poly-methylmethacrylate disk labeled with tritium and tritiated water. It was found that the present detection system satisfied the basic performance for measurements of the low energy X-rays and it is applicable to non-destructive measurements of high-level tritiated water in a flow system.
