| Abstract Scope |
Simulating neutron radiation attenuation by the metal matrix and reinforcing particles for neutron absorbing metal matrix composites can guide design and optimize future experimentation. Various metals and their alloys are evaluated as the matrix with respect to neutron shielding ability. Neutron transmission simulations using the Japan Atomic Energy Agency's PHITS radiation transport code predict the macroscopic cross-section for neutron absorption. The results illustrate how particle size and associated volume fraction affect the radiation shielding ability of metal matrix composites. It is anticipated that this data can be used to select an appropriate metal matrix and particle size and volume fraction for structural materials used in aerospace and other high radiation environments. |
