[en] During the last decade, the interest in the nuclear industry for improved nuclear code
systems has been growing. Based on an assessment of different reactor concepts (PWR …

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 …

The subgroup methods are a category of self-shielding methods based on the use of
probability tables to compute group-averaged quantities. The probability tables traditionally …

Since 2008, CEA has been developing a new generation of multi-purpose code called
APOLLO3®. APOLLO3® integrates lattice calculation and core simulations into a single …

In this paper we present the last improvements of the recently proposed linear surface (LS)
characteristics scheme for unstructured meshes. First we introduce a new numerical tracking …

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 …

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 …

On the 2nd of December 1942 the reactor Chicago Pile-1 (CP-1) was ready for a
demonstration. Fermi described the apparatus as" a crude pile of black bricks and wooden …
