title = "NUMERICAL AND EXPERIMENTAL PARAMETRIC INVESTIGATION OF RAREFACTION WAVE PROPAGATION ACROSS AN ORIFICE PLATE",
abstract = "Loss Of Coolant Accident causes the propagation of a transient rarefaction wave within the primary circuit that generates a transient pressure load on the baffle surrounding the reactor core. This is the result of nonidentical travel times of the rarefaction wave between the two sides of the baffle: the reactor core on one side and the by-pass between the baffle and core barrel on the other. The two zones have different geometrical characteristics, in particular the perforated reinforcement plates in the by-pass significantly influence wave propagation. Representing these obstacles in numerical simulations of the primary circuit requires the use of simplified models. A study on the accuracy of these models is hereby proposed, through a detailed comparison between numerical simulations realized with the EUROPLEXUS software and experimental results obtained on the MADMAX facility.",
