Abstract
Nuclear radiation that penetrates the skin of an exothermic kill vehicle can damage sensitive electronic components on board. Radiation shields to protect these components must absorb the radiation (x-rays, neutrons, or gamma rays), absorb any cascade by-products, such as photoelectrons, and mitigate the effects of stress waves (shocks) generated by the absorption process. HY-Tech is proposing a multi-layer shield consisting of a high Z outer layer to absorb high energy x-rays (100-300 keV) and a porous B4C middle layer, which provides rigidity to the structure and moderates the neutron flux. The porous B4C layer absorbs photoelectrons emitted by the x-ray absorption in the outer layer and acts as an acoustic miss-match to mitigate shock wave propagation to the internal components. The Phase I effort will fabricate B4C samples with a high Z absorbing layer on one side. The transmission of 100-300 keV x-rays through this two-layered shield will be measured on a x-ray simulor. The neutron shielding and shock isolation properties will be calculated using analytical and numerical techniques.
