计算机技术在核能分析计算的发展与应用OA

Nuclear energy,as a clean energy that can be applied on a large scale,is an important development direction for the current and future world energy market.With the emergence and development of computer technology,using computer programs or software to simulate the design and structure of nuclear reactors is an efficient and accurate method.This paper firstly introduces the development of computer technology in the field of nuclear energy,and introduces the analysis programs and platforms devel-oped by domestic and foreign research institutions based on computer technology.Secondly,the application of simulation calcula-tion in the field of nuclear energy analysis is studied.Taking the PWR fuel rod assemblies used in large commercial nuclear power plants as the research object,the heat transfer model and mechanical model for fuel rod assemblies analysis are established based on the commercial finite element platform COMSOL.Finally,the steady-state operation and transient start-up conditions of the PWR fuel rod assemblies are simulated,and the transient start-up characteristics of the fuel rods are analyzed.The research results of this paper provide an effective reference for the simulation calculation of nuclear reactor assemblies.
