            Cement-based concretes are commonly used for managing radioactive waste due to their low cost and acceptable radiation shielding properties. However, the potential of using oil shale ash as an admixture in concrete for the radioactive waste packaging has been left unnoticed. The present work aims to demonstrate the radiation shielding properties of developed concrete mixes with the oil shale ash and basalt-boron fibers for the spent nuclear fuel management at the Ignalina NPP. Concrete composite materials were placed in the CONSTOR RBMK-1500/M2 cask model to estimate radiation shielding properties. OpenMC, MCNP, SCALE and Serpent codes were used for the estimation of radiation shielding properties. It was demonstrated that the cask with developed concrete composite material can meet the safety limit.
