Abstract
This paper presents a comparison between experimental results and numerical simulations of a reactor pressure vessel internals response due to a rapid depressurization associated to a pipe break. The experiment is designed to fulfil conditions relative to a Pressurised Water Reactor (PWR). The numerical simulation is performed with the computer program package ADINA. The calculations are performed both with and without Fluid Structure Interaction (FSI) effects. It is shown that FSI effects are very important for this problem. The comparison between experimental and numerical results is performed for local pressure in the water and displacements and strains in the reactor vessel and internals. Our experience is that good numerical results can be achieved for this type of loading for all compared quantities. Note that the experiment was set up to show the importance of FSI-phenomena, the effect of this could then be stronger in the experiment compared to a “real” case.
