在线氚甄别测量中,甄别装置的甄别性能直接决定着测量数据的准确性和可靠性。本文基于 Nafion膜进行了氚甄别测量的实验研究,分别在 HTO、HT以及 HTO+HT气氛下进行了实验,详细分析了气体瞬时流量、温度等条件对甄别性能的影响。结果表明,HTO在 Nafion膜中的渗透率很容易达到90%以上,HT在Nafion膜中的渗透率小于0.19%。在适当的温湿度及气体流量条件下,一级 Nafion干燥器在氚甄别测量中对 HTO有99%以上的分离效果,HTO对 HT的甄别比可达106以上。

During the online monitoring for tritium,the effectiveness of measurements is decided by the performance of the discrimination devices (Nafion).Experiments have been made to examine the performance of Nafion in terms of gas instantaneous flux and temperature.The research shows that a permeability as high as 90% can be reached for HTO in the Nafion while less than 0.19% for HT.More than 99% of HTO can be separated which gives a discriminating ratio between HTO and HT above 106 with a single-stage Nafion provided that a good control of temperature and humidity as well as gas instantaneous flux have been achieved.
