TL;DR: In this article, the spreadability of corium-concrete mixtures having large solidification ranges even with viscous silicic melts, the change of microstructure due to cooling rates, the occurrence of a large thermal contact resistance at the corium substrate interface, the presence of a steep viscosity gradient at the surface, the transient concrete ablation.

TL;DR: In this paper, three two-dimensional Molten Core-Concrete Interaction tests have been conducted in the VULCANO facility with prototypic oxidic corium.

TL;DR: In this article, a test-section was designed to identify stiffness, damping and mass coefficients of a fuel assembly under axial flow, and previous studies have shown that the bypasses have an influence on the identified coefficients.

TL;DR: In this paper, a model simulating the response of the core to a seismic excitation has been developed, and full scale tests considering one fuel assembly are performed to identify coefficients (added mass and damping) that will be used as inputs in the models.

TL;DR: In this article, the first four modes of the fuel assembly are excited, two confinements are tested, and a parameters identification method based on a proper orthogonal decomposition (POD) analysis is proposed.
