摘　　要：在钠冷快堆的安全评估中,分析钠泄露导致的池式钠火事故下燃烧产物的气溶胶行为尤为重要。本文采用将池式钠火燃烧模型与气溶胶动力学模型耦合的方式,开发了池式钠火事故下燃烧产物气溶胶行为分析程序REBAC-SFR,基于该程序模拟了SAPFIRE-D1和ABCOVE池式钠火实验,并与实验数据进行了对比。结果表明,本文开发的程序具有良好的可靠性和正确性,可为钠工艺间内池式钠火事故下燃烧产物气溶胶行为分析研究提供理论工具。In the safety assessment of sodium-cooled fast reactor(SFR),it is particularly important to analyze the aerosol behavior of combustion products in sodium pool fire accident caused by sodium leakage.In this paper,the analytical program REBAC-SFR for aerosol behavior of combustion products in sodium pool fire accident is developed by coupling the sodium pool fire combustion model with the aerosol dynamics model.Based on this program,SAPFIRE-D1 and ABCOVE sodium pool fire experiments are simulated and compared with the experimental data.The results show that the program developed in this paper has good reliability and correctness,and can provide a theoretical tool for the analysis of the aerosol behavior of combustion products under the sodium pool fire in the sodium process room.
