dc.description.abstract	In the near-past we introduced a simplified linearized model for the fluid-coupled vibratory responses of nuclear fuel racks, neglecting three-dimensional flow effects and assuming small gaps between the fuel assemblies. In this paper, using the same basic approach, we generalize the above-mentioned model to account for nonlinear squeeze-film and dissipative flow effects. The proposed methodology can be automatically implemented on a symbolic computer environment. Numerical simulations highlight the significance of nonlinear flow effects at high vibration amplitudes, yielding more realistic predictions.	por
