摘　　要：在核电厂极限设计事故工况时,由于动力载荷的作用,反应堆冷却剂系统内部存在诸多流体与固体耦合现象,采用流体附加质量的方法等效系统内部的流固耦合现象。对反应堆冷却剂系统中存在的流固耦合附加耦合质量的计算方法进行研究,梳理燃料组件之间、吊篮与燃料组件之间、压力容器筒体与吊篮之间以及蒸汽发生器传热管之间流固耦合质量的计算方法,有效模拟流体和固体之间的耦合效应,为建立动力分析模型提供有力的技术支持。When considering accident conditions of nuclear power plant, there are many fluid-structure interaction phenomena due to dynamic loading of the reactor coolant within the system. The general method of fluid added mass attached to the structure is used to equal fluid-structure interaction phenomena. The method of calculating the added mass in the reactor coolant system is studied. Added mass and coupling mass in the regions between fuel assemblies,between core barrel and fuel assembly, between core barrel and reactor pressure vessel, between tube bundles in steam generator are researched to effectively simulate the interaction effect between the fluid and structure, and to provide a powerful technical support for building the dynamic analysis model.
