Resumo: In this work, it is presented the application of a spectral nodal method (coarse-mesh) in the solution of one-dimensional neutron shielding problems, in the discrete ordinates and energy multigroup formulations. This method, named Modifed Spectral Deterministic (MSD), represents a modification of the calculation structure of the neutron angular flux in the sweeping process used in the Spectral Deterministic Method (SDM). The numerical results for 3 model-problems are shown, with different dimensions, number of energy groups and types of boundary conditions in using a computational application developed in the programming language C++.

Este método, denominado Modi ed Spectral Deterministic (MSD), representou uma modificação na estrutura de obtenção dos fluxos angulares de nêutrons emergentes no processo de varredura que foi utilizado no Método Espectral Deterministico (do inglês Spectral Deterministic Method, SDM). São apresentados os resultados numéricos para 3 problemas-modelo, com diferentes dimensões, número de grupos de energia, grau de anisotropia no fenômeno de espalhamento e tipos de condição de contorno, usando um aplicativo computacional desenvolvido na linguagem de programação C++.Universidade Federal do Rio Grande2021-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.furg.br/vetor/article/view/1347310.14295/vetor.v31i1.13473VETOR - Journal of Exact Sciences and Engineering; Vol. 31 No. 1 (2021); 94-103VETOR - Revista de Ciências Exatas e Engenharias; v. 31 n. 1 (2021); 94-1032358-34520102-7352reponame:Vetor (Online)instname:Universidade Federal do Rio Grande (FURG)instacron:FURGporhttps://periodicos.furg.br/vetor/article/view/13473/9111Copyright (c) 2021 VETOR - Revista de Ciências Exatas e Engenhariasinfo:eu-repo/semantics/openAccessLibotte, RafaelAlves Filho, HermesSilva, Fernando Carvalho2021-11-18T18:06:06Zoai:periodicos.furg.br:article/13473Revistahttps://periodicos.furg.br/vetorPUBhttps://periodicos.furg.br/vetor/oaigmplatt@furg.br2358-34520102-7352opendoar:2021-11-18T18:06:06Vetor (Online) - Universidade Federal do Rio Grande (FURG)false
