The Liquid Fuel Molten Salt Reactor (TMSR) is one of six advanced reactor concepts introduced by the Fourth Generation International Forum (GIF), featuring higher inherent safety, greater thermal power density and a more flexible fuel cycle. However, its liquid fuel, large thermal inertia, and unique passive residual heat removal system present new challenges for safety analysis. This paper extends the ATHLET 3.2 program to molten salt reactors by extending fuel salt properties, heat transfer, and liquid fuel point kinetics models, validated against Molten Salt Reactor Experiment (MSRE) benchmarks. Three transient scenarios, including primary loop flow, reactivity insertion and control rod withdrawal under anticipated transient without scram (ATWS) conditions, are modeled for a 150 MW TMSR to evaluate its safety performance. The results show that the extended ATHLET 3.2 program is suitable for TMSR analysis and confirms the high inherent safety of the 150 MW TMSR design.
