退役氚污染不锈钢管道除氚技术研究

Tritium Decontamination From the Decommissioned Stainless Steel Pipe

摘要: 针对退役氚污染不锈钢管道材质中氚的存在状况，对残留在管道壁中氚的去除技术进行了研究，在此基础上研制了一套退役氚污染不锈钢管道除氚实验装置，对其除氚性能进行了验证。结果表明，研制的不锈钢管道除氚实验装置对氚污染大于10⁶Bq/kg的不锈钢中氚的去污因子大于10³。

Abstract: According to the status of tritium from the stainless steel pipe which is used to the structure materials in some tritium-operating system, the technological process for tritium decontamination of the pipe is designed. An experimental device is then developed to decontaminate tritium from the decommissioned stainless steel pipe. The decontamination factor of tritium is higher than 10³when the tritium from the steel pipe is more than 10⁶ Bq/kg.
