Non-Newtonian spreading simulation of molten nuclear combustible
Abstract
In this paper, the non-dimensional 3D model for a free-surface non-Newtonian anisotherm flow is described. Its use for molten nuclear reactor core (corium) in the event of severe accidents is argued using similarity criteria. The model is then implemented in a finite element code based on the C++ library Rheolef. The resulting simulations are compared to experimental data from the prototypical corium spreading experiment VEU7.
