Inclusion of specific geometry of the beryllium blocks in the computational model of the MARIA reactor

The aim of this study is to analyze the accuracy of neutron-physical calculations made using the existing and alternative computational model of the basic cell component of the MARIA reactor core. For this purpose, an analysis of the accuracy of the calculation of the neutron flux and the effective multiplication factor by an alternative and existing computational model was performed. The results were compared with the exact model of the core primary cell prepared using the MCNP computational code.
