Study of neutron attenuation properties of super alloys with added rhenium

In this paper, the new generation of rhenium enriched super alloys with enhanced neutron attenuation properties was investigated. These materials provided improved neutron shielding capabilities compared to other shielding materials such as water, concrete, etc. The GEANT4 code was used to simulate transport of Am–Be source neutrons in new shielding materials. Neutron equivalent dose rate measurements were carried out to obtain the dose rate reduction. It was demonstrated that new rhenium enriched alloys are feasible for neutron shielding applications.
