Estimation of Pressure Vessel Lower Head Impact Force

P. Štemberk, M. Vaitová, M. Petřík
pages 290 - 291, full text

This paper presents a method of estimation of the concrete basement slab ablation acceleration during the nuclear severe accident. The molten fuel creates the corium pool in the lower part of the reactor pressure vessel. The stratification of the corium causes the focusing effect which leads to the rupture of the lower head of the pressure vessel. The impact of the lower head filled with the corium affects the subsequent corium-concrete interaction. The method of estimation of the impact load on the concrete basement slab and the related determination of the depth of the crushed concrete layer are presented.
