研究了氚在Ｐｕｒｅｘ流程中的行为。测量了氚和ＨＮＯ_３在３０％ＴＢＰ－煤油和水相之间的分配比，研究了γ辐照和铀浓度对氚分配的影响及辐照对氚在有机相中保留的影响。萃取到有机相中氚的洗涤实验表明，洗涤是一种氚在两相间重新分配的简单过程。对氚在一循环中的行为进行了台架实验，结果表明，１Ａ混合－澄清槽（６级萃取，９级洗涤）中对氚的去污系数在１０~４以上，并且氚主要集中在１Ａ的萃取段，残留在１ＡＰ中的氚易在附加的氚洗槽（５级）中去除。
The behavior of tritium in the Purex process was studied. The distribution ratios of tritium and HNO_3 between 30% TBP and kerosene were measured. The effect of γ irradiation and uranium concentration on the distribution of tritium and the effect of irradiation on the retention of tritium in the organic phase were studied. Washing experiments of tritium extracted into organic phase show that washing is a simple process of tritium redistribution between two phases. A tidal experiment was conducted on the behavior of tritium in a cycle. The results showed that the decontamination factor of tritium in 1A mixed-clarification tank (6-stage extraction, 9-stage washing) is above 10 ~ 4 and tritium is mainly concentrated in 1A The tritium residue in 1AP is easily removed in an additional triton tank (grade 5).
