摘要
本文讨论了两维快堆中子扩散方程的有限元数值逼近方法,给出了收敛性证明,利用自动剖分技术编制了两维多群中子扩散方程有限元计算程序 FEM2D,对快堆临界问题进行了一系列数值计算,并与国外有限元计算结果及其它方法计算结果进行了分析比较,得到了满意的结论。
This paper discusses the finite element approaching methodfor two-dimensional neutron diffusion equations of fast reactorand proves the convergence.The finite element code FEM2Dwhich calculates the two-dimensional mutigroup neutron diffusionequations is made out with auto cut skill.Some numerical calcu-lations of fast reactor critical problem are provided,the resultsare studied and compared with the results which gained by abo-ard finite element method and other methods,and the satisfiedconclusion is gained.
