Analysis of Fission Product Behavior in Bypass Containment Severe Accident Induced by SGTR of AP1000

School of Mechanical Engineering, Shanghai Jiaotong University, Shanghai, 200240, China

摘要: 建立非能动先进堆AP1000的事故分析模型,选取蒸汽发生器传热管破裂(SGTR)始发的安全壳旁路型严重事故,在研究事故进程的基础上,分析计算事故下裂变产物释放和迁移的特性,重点关注惰性气体、挥发性裂变产物和非挥发性裂变产物的分布,以及裂变产物在主系统和环境中的状态,最终计算释入环境的源项。

Abstract: The accident analysis model of AP1000 was established by using the integrated safety analysis code. On the basis of analyzing the progression of bypass containment accident initiated by SGTR, the characteristics including fission products release and transport were analyzed and computed, with focus on the distribution of inert gases, volatile fission products and nonvolatile fission products, and the status of fission products in primary system and environment. The source terms released to the environment are calculated.
