本课题是大型先进压水堆核电站重大专项“核电站国产新锆合金及关键材料辐照性能研究”中的子课题,即国产新锆合金小组件辐照考验。本文主要是对新锆合金小组件辐照考验进行热工水力分析,从而为整个设计提供安全评估依据。本文主要利用CFD软件进行三维模拟计算,首先构造几何模型、划分网格、指定边界条件类型和区域类型,然后导入处理器中选择需要的基本
This topic is a major project of large-scale advanced pressurized water reactor nuclear power station “research on the irradiation properties of domestic new zirconium alloy and key materials of nuclear power station ”, that is, the domestic new zirconium alloy components irradiation test. In this paper, the thermodynamic and hydraulic analysis of the irradiation test of the new zirconium alloy components is mainly carried out to provide the basis for safety assessment of the entire design. In this paper, CFD software is mainly used for three-dimensional simulation calculation. First, the geometric model is constructed, the grid is divided, the type of boundary conditions and the type of the boundary are specified, and then the selected basic
