目前世界上几乎所有的乏燃料后处理设施均选用 Purex流程。红油爆炸事故是 Purex流程后处理设施安全研究的焦点问题之一。本文对典型后处理设施共去污分离循环工段的中放废液蒸发器的红油爆炸事故进行了事件树-故障树分析。结果显示，红油爆炸事故的发生频率极低；人因失误和共因失效对整个红油爆炸事故的贡献很大。应采取相应措施，以预防事故的发生。

Almost all spent fuel reprocessing facilities have adopted Purex process .T he red oil explosion is a great concern in safety study of spent fuel reprocessing facilities adopting Purex process .The event tree and fault tree analysis was performed for the red oil explosion of a medium level radioactive waste liquid evaporator for the collective decontamination and separation cycle segment in a representative reprocessing facility in this paper . The results show that the occurrence frequency of a red oil explosion is extremely low ,and human errors and common cause failures are major causes to a red oil explosion . Therefore , some relevant measures should be taken to prevent such accidents .
