N2 - Currently generation IV nuclear reactors are being developed. One of the possible designs is the lead-cooled fast reactor, of which MYRRHA is a prototype. The aim of this study is to gain insight in the eigenmode characteristics of fuel rods immersed in axial flow. Current design practice is to use semi-empirical models to provide vibration characteristics. This study on the other hand takes the entire 3-dimensional flow field into account to determine the eigenmode characteristics. Therefore partitioned simulations are performed using the IQN-ILS algorithm on one empty fuel rod. Initially the rod is deformed according to an in-vacuo eigenmode which is then released in an unsteady FSI-simulation. Simulations are performed with both symmetric and periodic boundary conditions to analyze the effect of boundary conditions in the flow field .
