Deterministic analyses of YALINA-thermal subcritical assembly with DRAGON-PARTISN software

This study analyzes the YALINA Thermal subcritical assembly with a deterministic calculation methodology. Within this methodology, the DRAGON code, developed at Polytechnique de Montreal (Canada), has been used to generate the macroscopic cross sections for more than 50 different zones of the assembly. The DRAGON code used the WIMSD nuclear data library with 179 energy group microscopic cross sections. In the DRAGON code, the geometry of the assembly has been simplified. The generated macroscopic cross sections have been used in the PARTISN code, developed at Los Alamos National Laboratory (USA), which modeled the facility in a detailed three-dimensional geometry. The calculations focused on the kinetic parameters and the 3He reaction rate profile, which has been compared with the experimental measurements. (author)
