Abstract
Nuclear industry needs tools to design reactor cores in case of earthquake. Simulation using a fluid-structure model of the core subjected to a seismic excitation has been proposed. A parametric study has been conducted to observe the effect of confinement length and elasticity modulus on the added stiffness effect. The modeling used to make the parametric study showed good agreement with experimental results. Simulations showed that the added stiffness reaches a maximum for a confinement around 20 mm, and that the added stiffness should be negligible in a real core configuration.
