Four dimensional matrices are obtained, which include three spatial coordinates and values of specific physical characteristics of radiation fields, based on the obtained data, by partitioning into specific layers, constructed and presented three-dimensional distributions of radiation fields to determine areas with maximum radiation flux and critical places inside UZZK container. The areas of the side walls of the container that are most vulnerable to radiation loads are determined and the difference of radiation distributions of these areas from radiation sources is determined. The additional influence on the radiation load due to the heterogeneous structure in the zones of the container, denoted by us as A, B and C, is determined. Three-dimensional distributions of the deposited energy values in the middle of the container material are obtained. The obtained results will significantly increase the separation of the method in the subsequent iterations of the simulations and significantly reduce the volume elements when obtaining three-dimensional distributions of physical quantities. This will allow moving from modeling the distribution of radiation fluxes and absorbed energy to modeling the three-dimensional spatial distribution of initially ejected atoms (PVA) of UZZK materials, and identifying places with maximum levels of PVA and as a consequence with the probability of corrosion.
