High entropy alloys often have excellent mechanical properties that conventional alloys based on one or two elemental combinations do not have. It is necessary to investigate whether these alloys can be used for nuclear applications with their properties such as high strength, fracture toughness, high corrosion and wear resistance. In this study, the thermal and fast neutron absorption properties of high entropy alloys with three different contents including Ti, Ta, Hf, Nb, and Zr elements were investigated. Their usability for nuclear applications has been demonstrated. In order to understand whether a material is neutron shielding, important neutron attenuation parameters such as effective removal cross section, half value layer, mean free path and neutron transmission factor (NTF) need to be determined. These reduction parameters were theoretically found with the Monte Carlo simulation GEANT4 code for epithermal and fast neutrons. It was found that Nb25 Ti25Hf25Ta25 has the best neutron shielding capacity among the investigated High entropy alloys. According to found all the results in the present work, we suggest that the all high entropy alloy samples can be used against any neutron leaks in nuclear operations.
