The present work is a continuation for the multigroup scalar neutron flux and multigroup precursor concentration model, here two energy groups and one delayed neutron precursor concentration. We determine a general solution for this problem consideri

In this work we report an analytical representation for the solution of the radiative-conductive S N equation in inhomogeneous plane-parallel atmospheres considering arbitrary continuous and sectionally continuous functions for the albedo. The basic

In this work the latest developments a Monte Carlo simulator with continuous energy is reported. This simulator makes use of a sum of three probability distributions to represent the neutron spectrum. Two distributions have known shape, but have vary

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 recu

In the present work we discuss a system of partial differential equations that model neutron space-kinetics in cylindrical geometry and are defined by two sectionally homogeneous cylinder cells, mono-energetic neutrons and one group of delayed neutro

In this work, we present a solution for the radiative–conductive transfer equation in cylinder geometry for a hollow cylinder. We discuss a semi-analytical approach to the non-linear SN problem, where the solution is constructed by Laplace transfor

The present discussion is an extension of a new model recently developed for neutron point kinetics, where the reactivity is decomposed in terms of short and long timescales. The short timescale corresponds to the operational control of the reactor,

Recently, the radiative conductive transfer equation in cylinder geometry was solved in semi-analytical fashion by the collocation method in both angular variables, using the S N procedure. Upon application of the decomposition method the resulting r
