A model of the experimental TALL-3D facility is prepared using the coupling between the System Thermal-Hydraulics code ATHLET and the Computational Fluid Dynamics code ANSYS CFX. For the validation of this coupling approach, uncertainty and sensitivity analysis methods are implemented and applied to the model. Conclusions are drawn with regard to the respective benefits of each method and to the quality of the model response against the experimental data acquired during several transients. This work is carried out within the framework of the development of multiscale computational tools for the design of future liquid metal nuclear reactors.
