Abstract

From the terror-attack of September 11, 2001, the design of new high-priority buildings demands improved safety requirements. This applies to newly built nuclear facilities, including the Paks 2 major investment. These increased safety requirements require that the reactor containment of the planned nuclear power plant must also resist significant aircraft collisions. During such a large collision, a wide range of extreme encumbrances load the structure, from the crushing of the fuselage, the penetration of the detached engines, to the explosion of the leaking propellant. Only a few results of such experiments are known, therefore, theoretical considerations and numerical studies play important roles, as well as the application of various empirical formulas during the design. However, reliable measurement results are required to validate the calculations. Unfortunately, the scope of the results found in the literature is not sufficiently defined, so in a cooperation the Budapest University of Technology and Economics and the Hungarian Army Institute for Modernization was investigated the damage of concrete targets as a function of projectile velocity and concrete quality.
