APOLLO3® is a common project of CEA, AREVA and EDF for the development of a new
generation code system for core physics analysis providing improved accuracy, flexible …

In this paper we describe some recent developments in the Method of Characteristics (MOC)
for three-dimensional (3D) extruded geometries in the nuclear reactor analysis code …

In recent years a solver based on the Method of Characteristics (MOC) allowing the
treatment of 3D extruded geometries has been developed inside the TDT code of APOLLO3 …

Abstract Design of modern sodium fast reactors such as the French SFR project ASTRID are
axially heterogeneous in order to maximize neutron leakage and therefore improve their …

In the past few years, developments in the APOLLO3® deterministic code have mainly been
devoted to Fast Reactor applications. In this paper, we investigate the possibility of using …

A three-dimensional (3D) axial capabilities have been recently implemented in the TDT-
MOC solver (Method of Characteristics solver), module of the French deterministic core …

This thesis aims at improving the modelling of Pressurized Water Reactors (PWRs). Nuclear
reactors in general can be considered as multiphysic systems, as their accurate …

This thesis introduces a polynomial expansion for the axial profiles of macroscopic cross
sections in TDT, the 3D Method Of Characteristics (MOC) solver of the APOLLO3R code …

The new deterministic platform APOLLO3® offers three different self-shielding models:-the
Sanchez-Coste model currently used in APOLLO2 for Light Water Reactors production …

Recently a solver based on the Method Of Characteristics (MOC) for 3D extruded
geometries has been developed in the APOLLO3® project [1]. In this method the domain is …
