Surface power and nuclear electric propulsion in space necessitate the development of high energy density, long term continuous power sources. Research at The Ohio State University under the NASA Ralph Steckler Space Grant Colonization Research and Technology Development Opportunity has identified molten salt reactors (MSRs) as a potentially appealing technology for high power, high temperature space fission systems. This thesis examines component specific design related to thermal transport in an attempt to further establish the feasibility of MSRs in space. Specifically, the optimization of the associated heat exchangers for a Brayton power cycle is discussed in detail. In addition, power cycle and secondary coolant selection, material selection, and general MSR design considerations are discussed. The primary heat exchanger was optimized to maximize the margin to super prompt critical (MSPC), with a final MSPC equal to 513 pcm. The secondary and tertiary heat exchangers were optimized to minimize helium pressure drop, with a combined pressure loss of 2.62 kPa obtained.
