摘要：研究了Y板从中子辐照Li中回收氚T的实验研究，设计了Y热阱从流动的IFMIF Li靶环中去除氚T。在300-500°的Y板上成功地除去了Li在0.01 ~ 0.05ppm的摩尔分数中产生的T。还原T与生成T之比随温度和浸泡时间的增加而增加。Li释放的T以HT为主，不吸收Y的以HTO为主。SEM-EDX分析表明，Li中不仅有T的转移，还有作为杂质的O的转移。用HF处理Y能有效去除接收Y板上形成的氧化物，提高Y板的加氢速率。本文给出了设计用于IFMIF流动Li靶回路的Y型热阱的条件。
Abstract The recovery of tritium, T, from neutron-irradiated Li by a Y plate was experimentally investigated, and a Y hot trap was designed to remove T from a flowing Li target loop of IFMIF. T generated in Li ranging from 0.01 to 0.05ppm in molar fraction was successfully removed by a Y plate at 300-500°. The ratio of recovered T to generated one increased with temperature and immersion time. HT was the main chemical species of T that was released from Li, while HTO was the main one without Y absorption. SEM-EDX analysis revealed the transfer of not only T but also O originally included in Li as an impurity. Treatment of Y by HF was effective to remove oxides formed on the as-received Y plate and enhanced its hydrogenating rate. Conditions of a Y hot trap designed for the flowing Li target loop of IFMIF are given in the present paper.
