摘　　要：在现场闭路循环工作模式下，采用中国辐射防护研究院研制的小型可移动式除氚器对微量（（0．5～1）×10^-6）气态氚进行脱氚试验。试验结果表明：催化床在450℃工作温度下，空气闭路循环流量为3．8m^3／h时，除氚器可在114min内将1m^3密封不锈钢罐空气中的氚浓度由4．62×10^6 Bq／L降至4．62×10^3Bq／L。同时，论证了除氚器在现场使用的适应性与安全性，并对其研制和现场性能试验中发现的技术问题进行了论述。De-tritiation experiments of air with tritium gas in a glove box at closed-loop circulation mode were carried out by a compact tritium removal equipment（TRE） developed by China Institute for Radiation Protection. The TRE will decrease the concentration of tritium in air of glove box with 1 m^3 from 4.62 10^6 Bq/L to lower than 4.62× 10^3 Bq/L within 114 min at air flow rate of 3.8 m^3/h and working temperature of 450 ℃ of catalytic bed. The applicability and safety of the TRE for use as tritium facilities is demonstrated also and some technical problems are discussed in this work.
