| Description | Journal: Journal of Physics: Conference Series A fundamental knowledge of the fuel assembly behaviour in different situations of burning is required for safe and economic nuclear power generation. Due to the importance of a fuel rod behaviour modelling in high burnup, in this paper, the spatial discretization used for the fuel assembly and burnup calculations influences significantly the results. The effective multiplication factor, total radial atomic distribution during the burnup of uranium dioxide $(UO_{2}$) fuel, fission products and actinides total atomic density and their variations besides the speed of calculations by increasing burnup and the burnup steps were studied for different spatially discretized models of fuel assemblies for VVER-1000 reactor in an operational cycle using the MCU Monte Carlo code. The effects of spatial discretization and the number of burnup steps appear slightly with the increasing of the discretization layers and the steps numbers. |
