Coupled Radiation Transport / Thermal Analysis Of The Radiation Shield For A Space Nuclear Retractor, William John Barattino
Nuclear Engineering ETDs
The renewed interest of conducting operations in space has given rise to re-establishment of space reactor systems development. The current SP-100 program is focussing on design of a 100 kW nuclear e reactor for space application. This research project investigated the coupling between radiation transport, energy deposition, and temperature distribution for a variety of space reactor shield configurations. The basic shield design consisted of tungsten [W], and natural lithium hydride either cast or pressed into a stainless steel matrix [LiH(Nat)].
For a nuclear reactor operating at a power level of 1.66 MWth, temperature feedback effects on energy deposition …
