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 …

A linear source (LS) approximation scheme is presented for the two-dimensional method of
characteristics (MOC). The LS approximation relies on the computation of track-based …

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 …

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 …

ABSTRACT A Linear Source (LS) approximation has been implemented in the two-
dimensional Method of Characteristics (MOC) transport solver in a prototype version of …

Particle conservation, otherwise known as particle balance, is one of the main properties to
examine when considering any transport discretization. In the past, particle conservation has …

This work seeks to improve upon an existing formulation of the Method of Characteristics
(MOC) with a Linear Source Approximation (LSA) for problems that use nonconstant cross …

The development of higher-order method of characteristics (MOC) discretizations has
become of great interest to improve the performance of solvers based on the standard …

In this paper, we report the development and verification of a method of characteristics
(MOC) code, PEACH, at Shanghai Jiao Tong University. Both the usual flat-source step …

This paper features the development of angle-dependent linear source (ADLS)
approximation for the 2D/3D Method of Characteristics (MOC)/Diamond Differencing (DD) …
