CFD方法在压水堆安全分析中的应用现状和发展趋势

Status and development trend of CFD method used in pressure water reactor safety analysis

为更好地利用CFD方法解决压水堆安全分析问题,简要介绍CFD方法,着重阐述其在硼稀释、混合和热分层以及受压热冲击等压水堆安全分析问题的应用现状,并提出CFD与系统程序的耦合计算、流固耦合计算和CFD与中子动力学程序的耦合计算将是CFD方法在该领域的发展重点.

To make better use of CFD method in pressure water reactor safety analysis,the CFD method is introduced briefly and its application in boron dilution,mixing and thermal stratification,and pressurized thermal shock in pressure water reactor safety is especially detailed.The techniques such as CFD and system program coupling calculation,fluid-structure coupling calculation and CFD and neutron dynamics program coupling calculation should be the development focus of the CFD method application in nuclear reactor safety analysis.
