摘　　要：为了监测快堆正常运行工况下覆盖气体系统中氩气的质量状况,保证快堆安全运行,采用长距离固定管线取样、集中测量的方法实现对快堆氩气中微量氧和水的间断在线分析.实验结果表明:当氩气中水的体积比为6μL/L时,测量的相对偏差<10%;当氩气中氧的体积比为10μL/L时,测量偏差为3%～9%;当氩气中氧的体积比为2μL/L时,测量偏差为24%～31%.不同测量时间的测量值扣除相应系统本底后其结果接近样气中水或氧的体积比,基本达到设计的技术指标要求.In order to ensure a safety operation of a fast neutron reactor,the quality of argon gas should be monitored in cover gas systems of the reactor at the normal operation.The research provides a method to realize an discontinuous online analysis for trace water and oxygen in argon gas by sampling gas in a long distance pipeline than concentrated determining. The experiments demonstrate that when a level of water in argon is about 6 μL/L,the relative standard deviation is less than 10%;When an level of oxygen is about 10 μL/L,the relative standard deviation is 3%～9%;When a level of oxygen is about 2 μL/L,the relative standard deviation is 24%～31%.The determining result could approach a level of a sample gas by deducting relevant background of systems from the determining result of different determined time.The method basically achieves technical demand of design.
