Monte Carlo Simulations Of a CANDU 6 Lattice Cell Using the GEANT4 Toolkit

Abstract

In our prior work, we demonstrated that the Geant4 Monte Carlo toolkit can be used to simulate a quasi-stable, time-dependent neutron population by renormalizing the population at regular temporalintervals. However, this method was only demonstrated with simple uranium spheres of varying diameters. The CANDU 6 lattice cell was chosen as an appropriate benchmark for our stabilization method because of its prevalence in current nuclear research. To simulate the lattice cell, periodic boundary conditions were added to the stabilization method so that the calculations could be performed on an infinite lattice. The results of these calculations were evaluated against several established codes, including DRAGON.
