Computer Deterministic Modelling of Nuclear Problems using Nodal Methods
Palavras-chave:Neutrons Transport Theory, Discrete Ordinates, Computational Modelling.
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 .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.
