Computer Deterministic Modelling of Nuclear Problems using Nodal Methods

Resumo

In this paper we propose a numerical nodal methodology for the development of a method of spectral nodal class [1, 2] which is tested as an initial study of the solutions (spectral analysis) of neutron transport equations in the formulation of discrete ordinates (SN ), in one-dimensional geometry, two energy groups, isotropic scattering and considering heterogeneous domains. These results are compared with the traditional fine mesh method DD and the spectral nodal method SGF [1].The solution algorithms problems will be implemented in a computer simulator made in MatLab language, the same that was used to generate the results of the reference work.
