摘　　要：氚安全工作是聚变反应堆核燃料循环工作的重要内容。文中对Zr2Fe合金吸氢反应的活化条件和热力学性能进行了研究,开展了氩气和氮气中的氘氚捕集实验。研究表明:Zr2Fe合金的氢化特性符合氚捕集的要求,它对惰性气氛中的氘和氚有相当高的捕集效率,是一种适合的氚捕集材料。Tritium safety-related research is one of the most important tasks of the fuel recycling in fusion reactors.The activation and thermodynamics character of Zr2Fe alloy were researched.On the foundation of hydrogen isotopes trapping experiments in Ar and N2,the mass transfer process in the once-through tritium trapping was researched.The research shows that the hydrogenation of Zr2Fe alloy fulfills the demand of tritium trapping,and Zr2Fe alloy is one of the most perfect tritium trapping materials owning to its rather high trapping efficiency for deuterium and tritium in inert atmosphere.
