This paper presents the mostortant developments implemented in the APOLLO2 spectral
code since its last general presentation at the 1999 M&C conference in Madrid. APOLLO2 …

The computer code DRAGON contains a collection of models which can simulate the
neutronic behaviour of a unit cell or a fuel assembly in a nuclear reactor. It includes all of the …

The method of characteristics (MOC) code CRX solves the three-dimensional transport
problem by the 2D/1D fusion method, in which MOC is used in radial 2D calculation and SN …

In this paper, dedicated polar angle quadrature sets for the method of characteristics (MOC)
are developed, based on the equivalence between MOC and the collision probability …

Major advances have been made in the HELIOS code, resulting in the impending release of
a new version, HELIOS-2. The new code includes a method of characteristics (MOC) …

This chapter presents a detailed description of the elements that comprise a lattice physics
code. Lattice physics codes are used to generate cross section data for nodal codes, where …

ABSTRACT The recent package APOLLO2. 8-MOC/CEA2005-SHEM developed by CEA is
undergoing a large validation program. First works of development and validation of a new …

The point we made in this paper is that, although detailed and precise three-dimensional
(3D) whole-core transport calculations may be obtained in the future with massively parallel …

A whole core transport module for hexagonal cores is developed and implemented in the
DeCART code. The module consists of a whole core ray tracing kernel for solving the two …

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 …
