Recently, there has been significant interest within the aerospace community to develop space based nuclear power conversion technologies especially for exploring the outer planets of our solar system where the solar energy density is very low. Like all power conversion systems, nuclear power conversion systems operate at efficiencies <100% resulting in the need to reject waste heat to space. Several different HRSs (Heat Rejection Systems) potential designs have been identified for rejecting NEP (Nuclear Electric Power) waste heat and several of them for a CBC (Closed Brayton Cycle) power conversion system are described herein and the results of their initial analyses presented. The analyses presented were performed as part of an initial trade study to recommend a promising HRS for advancement of its TRL (Technical Readiness Level). The trade study effort has concluded that the most preferred HRS for the CBC is the system utilizing simple heat pipes directly connecting the heat source with the heat sink. This system was recommended to be a primary focus during the next phase of the HRS development program.
