ABSTRACT A nuclear reactor's design and safety assessment relies on a calculation
platform consisting of a series of calculations performed using different simulation tools …

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 …

The CEA multiphysics tool combining the deterministic neutronics code APOLLO3® and the
computational fluid dynamics (CFD) platform TRUST/TrioCFD is used to model the first-ever …

In this paper the main features of the multiphysics schemes under development within the
EU H2020 CAMIVVER Project are presented together with their application to the simulation …

Reactor design requires safety studies to ensure that the reactors will behave appropriately
under incidental or accidental situations. Safety studies often involve multiphysics …

In this paper, we describe the implementation, verification, and numerical validation of
Generalized Perturbation Theory (GPT) capabilities in the TRIPOLI4® Monte Carlo code …

A method of dynamic homogenization was recently proposed as an alternative technique for
three-dimensional (3D) core calculations using a direct approach. This technique allows for …

The legacy subgroup method of the APOLLO3® code, denoted the SG-GR-383g method in
this paper, relies on the fine structure equation solved by the means of the General …

For some applications involving loading optimization for nuclear reactor cores, such as
irradiation experiments on Materials Testing Reactors (MTRs), or optimizing fuel assembly …
