Abstract As an important part of tritium plant, tokamak exhaust processing (TEP) system is used for extracting hydrogen isotopes from exhaust gas of tokamak which contains high concentration of tritium and deuterium. A detailed tritium transportation analysis for TEP system can help to obtain more precise and accurate results of tritium behavior in the tritium plant. In this paper, a detailed model of TEP system is established for the particular tritium transportation simulation during its operation. Mean residence time method is mainly used to simulate tritium transport in TEP, and a new calculating method is developed as optimization for Pb-Ag membrane processing. The tritium inventories and tritium losses of components in TEP system are obtained. The influences of reflux ratio of one membrane permeator on the tritium transportation behavior are also analyzed.

氚装置托卡马克尾气处理系统氚输运分析

摘要 作为氚装置的重要组成部分，托卡马克废气处理（TEP）系统用于从含有高浓度氚和氘的托卡马克废气中提取氢同位素。对 TEP 系统进行详细的氚迁移分析有助于获得更精确和准确的氚工厂中氚行为的结果。在本文中，针对特定氚运移过程中的氚输运模拟，建立了TEP系统的详细模型。平均停留时间法主要用于模拟 TEP 中氚的传输，并开发了一种新的计算方法作为 Pb-Ag 膜处理的优化。获得了TEP系统中组件的氚库存和氚损失。
