The molten salt fast reactor has the characteristics of returning to the vicinity of the initial reactor power due to the inherent safety even if the super-promt critical reactivity is applied. It is shown by neutronics and thermal-hydraulics coupling analysis using the FLUENT code with UDF and the RELAP5-3D code.
