Abstract: During a hypothetical severe accident in a Pressurized Light Water Reactor, the hot molten material mixture (corium) issuing from the degraded reactor core may generate a steam explosion if it comes in contact with water. Such an explosion may damage the structures and threaten the reactor integrity. The SERENA program is an international OECD project which aims at helping the understanding of the interaction mechanisms between the different components of the system (the hot molten pool, the liquid water, the generated fragments and steam) by providing experimental data and calculation analysis. In the KROTOS facility, energetic steam explosions can be triggered and studied using prototypic corium. CEA takes part in the SERENA program by performing experimental tests in the KROTOS facility designed to allow direct visual observations of melt injection into a water tank and mixing conditions (Huhtiniemi 2001). Still in the SERENA frame, pre- and post-test analysis are also carried out by CEA with the MC3D software. MC3D is developed by IRSN, it is a thermal-hydraulic multiphase flow code mainly dedicated to ex-vessel and in-vessel Fuel Coolant Interactions (FCI) studies (Meignen 2005). The purpose of this paper is to present the KROTOS experimental setup and instrumentation, expose the experimental results and a MC3D analysis of the recent KROTOS tests. The experimental results are presented for the KFC scoping test of the KROTOS program for which the results are not restricted to the SERENA partners. On the contrary, the KROTOS KS1 results being only available to the SERENA partners, the pre-mixing and explosion MC3D post-KS1 test calculations are proposed but without any scale. The calculation hypothesis leading to a good agreement with the experimental results (in terms of jet progression and void fraction in the system) are discussed.
General Note: The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows
