Description

This investigation aims to discover the utility of atmospheric cooling of residual heat in Martian applications (1.5 MWt). It also considers the possible terrestrial application (45 MWt) of these concepts. The peculiarities of atmospheric cooling require novel geometric arrangements and material selection. The average convection coefficient is derived and applied to ANSYS Transient Thermal analysis for both terrestrial and Martian environments. This preliminary analysis found that atmospheric cooling is a viable method of Martian passive cooling and may serve as a possible method in terrestrial conditions. The key finding of this investigation is that the inclusion of thin SiC conduction panels throughout the salt bodies significantly lowers the thermal gradient of the salt, allowing conduction to serve a greater role in passively cooling molten salt reactors.
