“…for the solution of the particle transport equation, mainly in multidimen sional geometries, is its applicability in several relevant problems (Fiveland, 1984;Kophazi, Lathouwers, and Kloosterman, 2009; Al-Basheer, Sjoden, and Ghita, 2010; Wagner et al, 2011;Sanchez, 2012). Despite the existence of G e n e ra l Expressions fo r A u x ilia ry E q u a tion s 353 well-established codes and a wide number of approaches dedicated to inves tigate such techniques (Yi and Haghighat, 2010;Zhang and Rahnema, 2012;Godoy and Liu, 2012;Rosa, Warsa, and Perks, 2013;Colomer et al, 2013), most of them are based on numerical schemes.…”

“…It is still a challenging problem to solve the neutron tra n sp o rt equation in a whole reactor core resolving all m aterial details of a reactor design (Sm ith and Rhodes, 2002;Lewis, Sm ith, and Palm iotti, 2009;Sanchez, 2012). A way to overcome some issues related to dim ensionality of such discrete problem s is to form ulate a tra n sp o rt problem on a coarse spatial grid in which each cell cov ers a small p a rt of a fuel assembly.…”

“…To deal with the contour terms that arise in the process, is used here a representation by constants, so that the equations in the variables x and y are treated by a coupled system. Results obtained by this formulation are presented, as well as some profiles of scalar flux.A Equação de Transporte, por sua grande aplicabilidade em diversos problemas realísticos, principalmente em geometrias multidimensionais, tem motivado a comunidade científica a investir cada vez mais no desenvolvimento de novas formulações para seu tratamento [1][2][3][4].Mesmo com a existência de uma série de códigos bem estabelecidos e formulações dedicadas à sua resolução [5,6], a maioria é baseada em esquemas numéricos, o que encoraja o estudo e o desenvolvimento de novas técnicas, de caráter analítico, que possibilitem um ganho de precisão ou de eficiência computacional [7,8].Para resolução de problemas multidimensionais envolvendo transporte de partículas, as formulações que mais tem se destacado são as baseadas nos Métodos Nodais [9-11], principalmente pelo seu desempenho quando associados à malhas grossas. Estas formulações, que geralmente requerem a subdivisão do domínio em células, fazem uso de esquemas iterativos para relacionar determinadas quantidades médias definidas no processo.…”
