3D CORE CALCULATION BASED ON THE METHOD OF DYNAMIC HOMOGENIZATION

The classical two-step calculation scheme has been extensively used to perform three-dimensional deterministic core calculations thanks its fast results. On the other hand, direct 3D transport and 2D/1D Fusion methods, mostly based on method of characteristics, have recently applied showing a prohibitive computational time for routine design purposes as well in context multiphysics depletion calculations, due current machine capabilities. Dynamic Homogenization is here proposed an alternative technique that may lie between approaches terms precision performance. In this work, NEA ”PWR MOX/UO2 Core Benchmark” configuration. Comparison pin power relative errors cost against are presented.
