Computational Analysis of Additively Manufactured Space Nuclear Reactor Shielding
Project Goals and Description:
Nuclear reactors emit ionizing radiation that can be harmful to people and electronic equipment. Shielding materials that attenuate this radiation can significantly increase the size and mass of nuclear-powered spacecraft. Creating shielding materials that are viable for additive manufacturing processes may allow the production of customizable shield geometries that can reduce the size and mass of shielding materials needed to meet the spacecraft dose requirements. This project will use Monte Carlo methods to evaluate the effectiveness of proposed space reactor shielding materials based on composition and geometry.
Grand Challenge: Not applicable.
