Simulant fluid experiments for core-concrete thermal attack: Chapter 12

This study examines the relevant features of the core-concrete interaction with simulant materials. Novel aspects of these simulations are the crusting of pool material and the melt-point suppression of the pool during source-driven, prolonged endothermic substrate erosion. These experiments demonstrate that heat transfer in such systems is controlled by these features. Overall erosion is thus governed by a balance between the energy input, initial super-heat, upward losses, and specific erosion enthalpy
