N2 - Mass optimization studies of potential upper and lower axial shields for the Affordable Fission Surface Power System are described in detail and a complete shield is developed to meet the radiation dose requirements of 10 14 n/cm2 fast (E>1 MeV) neutron fluence and 2 Mrad gamma dose at the Stirling power converters and 5 rem/yr at a lunar outpost located 1 km from the center of the reactor. The upper and lower axial shield sections are developed separately, and then combined with the previously developed radial sections to produce a complete shield. Complete lithium hydride, borated water and boron carbide shields are developed. Lithium hydride yields the lightest complete shield at 6215 kg, followed by the borated water shield at 6663 kg, and the boron carbide shield at 8315 kg.
