Description

The application of the finite element method for solving the diffusion equation in regions with complex structure is described. The method of use of the response matrix in diffusion calculations of the regions including control rods or holes is suggested. The DTFEM computer code with test results is represented as the application of this method in two-dimensional R-Z, X-Y and R-φ geometries. The results of calculations by means of the numerical DTFEM code for the high temperature gas-cooled reactor model with control rod in reflector are given in comparison with the Monte-Carlo results. 8 refs.; 5 figs.; 3 tabs
