This work studied a coolant for a molten salt type reactor in terms of a natural circulation behavior. A natural circulation model using MATLAB was developed. This model is for the Molten Salt Loop currently under development at University of Ontario Institute of Technology to investigate aging related degradation effects and thermal storage applications of FLiNaK. The model’s purpose is to help design the flow loop and future experiments. Generation IV reactors were compared to provide an overview of new reactor concepts with an in-depth review of the Molten Salt Reactor MSR type. The molten salt history, design, and application were discussed. A review of thermophysical properties of different salt coolants is performed to understand the variation of cooling capability. The model’s results were compared to different fluid types to verify the trends. This gave a baseline upon which to refer when experimental results are ready and thus guide future research into molten salt studies.
