SMART (System-integrated Modular Advanced Reactor) is a small and medium-sized integrated reactor to produce an electric power and desalination simultaneously. SMART should be designed to withstand flow-induced loads generated by the coolant flow under both normal andtransient operations during the design period. In this study, we evaluated the flow-induced loads and flow characteristics in the axial and the circumferential directions of reactor internals using a down-scaled model of SMART prototype. This paper shows that the simulated results in the axial direction are in good agreement with the experimental data in the reactor coolant system.The flow-induced loads are irregularly distributed in the circumferential direction of the reactorinternals.
