利用CFD方法分析严重事故状态下放射源项迁移行为是大型先进压水堆重大专项课题“严重事故下放射源项及迁移机理研究”的重要研究内容之一,主要目的是探究使用CFD程序分析安全壳内裂变产物行为的方法。通过CFD程序和集总参数严重事故分析程序的比对分析及其与机理试验的对比,探索严重事故状态下非能动安全壳冷却系统对裂变产物迁移的影响机理,为严重事故的预防和缓解措施研究提供技术基础。
The CFD method to analyze the migration behavior of radioactive sources under serious accident conditions is one of the important research topics of major advanced PWR project “research on radioactive sources and migration mechanism under severe accidents”. The main purpose is to explore the use of CFD program Method to analyze behavior of fission products in containment. By CFD program and lumped parameter serious accident analysis program comparative analysis and comparison with the mechanism test to explore the passive accidental containment containment cooling system migration mechanism of fission products for the prevention and mitigation measures for serious accidents Research provides the technical basis.
