This paper presents a comparison of homogenization techniques implemented in the APOLLO3 platform for transport core calculations: standard scalar flux weighting and new flux–moment homogenization, in different combinations with (or without) leakag

The solution of the Boltzmann equation for particle transport is the central problem of radiation shielding. When the solution is attempted using Monte Carlo methods, the use of variance reduction techniques is unavoidable, because the probability th

In order to examine the performance of two deterministic codes, nTRACER and the standalone developing version of the IDT solver of APOLLO3 ® , problems from 2D single assembly to 3D full core were computed with the same macroscopic cross-section lib

In radiation protection studies, the goal is to estimate the response of a detector exposed to a strongly attenuated radiation field. Monte Carlo (MC) particle transport codes give the possibility to efficiently solve for such responses using several

In this paper we propose a new non-linear technique for accelerating the source iterations of the discrete-ordinates transport equation. The acceleration method, called Spatially Variant Rebalancing Method (SVRM), is based on the computation of the z
