摘　　要：本文利用数值仿真方法对密闭空间中氚发生意外泄漏的问题进行分析研究,计算了密闭空间内氚的浓度,得到了不同时间点氚的浓度分布规律,并分析了氚平均浓度的变化情况。结果表明,氚的浓度基本随时间按指数规律衰减。研究结果对科学制定氚泄漏应急处置措施及人员防护方案具有重要意义。This paper studied the accident that tritium leaked out from the container,and simulated the concentration of tritium in confined space.The factors affecting distribution of concentration of tritium were analyzed.The results reveal that the discharging of tritium is mainly affected by the ventilation rate.The research results have important significance on the development of tritium leakage emergency measures and personnel protection scheme.
