Abstract
The paper presents the results of modeling an L4 experiment using an ACE test facility (USA) on the interaction of the melt with concrete. The study aims to validate previously developed models of interaction between the melt and concretes of two particular types used in the construction of VVER-1000 NPPs. The experimental and calculation results were compared according to the movement of the concrete erosion boundary, the integral yield of hydrogen, carbon monoxide, and vapors of structural materials, as well as simulators of melt fission products. A satisfactory agreement was obtained according to all characteristics. The scatter of the results at the variation of main calculation parameters was estimated along with the degree of their influence on the concrete penetration depth.
