On multi-group neutron transport in planar one dimensional geometry: A solution for a localized pulsed source

Abstract

In this work we present a solution for the multi-group neutron transport equation in planar one dimensional geometry. As an application we consider a scenario with a localized pulsed source. The basic idea of this work consists in constructing a recursive system of equations leading to an analytical representation for the multi-energy group solution. The error control is obtained by properly choosing the recursion depth of the equation system. The authors also present an analysis of stability for the results of the recursive system. Numerical simulations are reported for a problem with pulsed neutron source.
