Modelagem Computacional de uma Blindagem de Nêutrons Utilizando Métodos Determinísticos

Abstract: Neste artigo, o problema denominado de fonte-fixa (blindagem de nêutrons) em meio não multiplicativo foi estudado. Assim, foi simulada computacionalmente a blindagem da fonte de nêutrons utilizando métodos numéricos determinísticos para estimar os fluxos escalares e angulares de nêutrons em um domínio unidimensional. A equação de transporte linearizada de Boltzmann para partículas neutras foi empregada na modelagem dos problemas estudados. Na resolução numérica da equação de Boltzmann, foram consideradas certa… Show more

“…The elements that comprise a nuclear reactor core must simultaneously meet both operating limits constraints and reactor con guration limits. The choice of a pertinent set of parameters is of fundamental importance to design of a nuclear core; for instance, the type of material employed [1]. Such complex task can be seen as an optimization process on a multimodal high dimensional space.…”
