摘　　要：1∶1地模拟金属钠冷反应堆的工程条件,建立了气体管路和手套箱氩气中微量水的分析方法.实验结果表明:当氩气中φ(H2O)≈3×10-4%时,测量的相对偏差<18%.在增压泵帮助下可以分析常压甚至微负压状况下手套箱内氩气中的微量水分.该方法完全满足了中国实验快中子反应堆CEFR对所使用氩气中微量水分的测量要求.This research simulates with 1∶1 a gas loop which will be constructed in a fast neutron reactor and builds a feasible sampling system to realize a concentrated and discontinuous on_line analysis for trace water in argon gas in a long distance multiple-pipeline with valves.The experimental results demonstrate that when a level of water in argon is about 3×10^(-4)%,the relative standard deviation is less than 18%. By means of diaphragm pump, the method can analyze trace water in argon of glove box in normal pressure and even trace negative pressure.The monitoring requirement of water in argon for CEFR is completely satisfied by means of this method.
