碎片床冷却分析程序开发

Code Development for Debris Bed Cool Ability Characteristics

从基本的质量、动量方程出发,针对多孔介质碎片床,开发基于有限元法的二维稳态堆芯碎片床分析程序,并分析系统压力、颗粒直径、孔隙率等相关参数对于碎片床冷却能力的影响,为压力容器的完整性提供理论依据。

In this paper, we developed a two-dimensional steady-state core debris bed analysis program based on the finite element method from the basic mass and momentum equations for porous media debris bed .The effects of debris bed＇s parameters such as the system pressure, particle diameter, porosity and other relevant parameters on the cool ability of the debris bed were also analyzed. Then provide a theoretical basis of the integrity of the pressure vessel.
