Causes and consequences of the 11 recorded explosion accidents in foreign countries are summarized and analyzed, and experience feedbacks of preventive measures and mitigation measures for explosion accidents in reprocessing facilities in China are thus formed. In particulars, for the preventive measures for explosion accidents in reprocessing facilities, one should pay attention to controling TBP content and acidity in the evaporation equipment, avoiding accidental exothermic reactions in the dissolution equipment, ensuring the effectiveness of the cooling system of the high-level waste liquid storage equipment, avoiding nitric acid substances accidental evaporation to dryness in storage equipment, and avoiding human error as well. For mitigation measures one should focus on the design of containment barriers for explosive thermal loads, explosive mechanical loads, explosion relief measures, the design of emergency cooling measures for high-level waste liquid and the design of appropriate emergency action as well.
