Flow-induced vibrations of parallel-plate fuel assemblies was measured using a virtual instrument with water flow at normal temperatures and pressures. Time and frequency domain results are presented for the dynamic response of the flow-induced vibrations for flow velocities between 0 and 18. 8m/s. The data shows that the vibrations of the parallel-plate fuel assembly with water flow contain all kinds of frequencies, with no dominant frequency. The assemblies experienced vibrations and departures which led ...
