Nuclear industry needs tools to design reactor cores in case of earthquake. A model simulating the response of the core to a seismic excitation have been developed. Full scale tests considering one fuel assembly are performed to identify coefficients

Damping is known to be a major parameter in the seismic design of nuclear facilities. Of special interest is the case of fuel assemblies in PWR plants, which, unlike other components, are submitted to axial flows: it has been known since the late 80s

In this paper, dynamic measurements of fluid velocity in the by-passes of a test-section representing a nuclear fuel assembly are presented. The test-section was designed to identify stiffness, damping and mass coefficients of a fuel assembly under a

In the hypothetical case of a nuclear reactor severe accident, the reactor core could melt and form a mixture, called corium, of highly refractory oxides (UO2, ZrO2) and metallic or oxidized steel, that could eventually flow out of the vessel and mix

In this paper, dynamic tests of a fuel assembly subjected to an axial flow are presented. Tests are performed for various flow conditions, at several displacement amplitudes. The first four modes of the fuel assembly are excited, two confinements are

Earthquakes can irreversibly damage nuclear power plants especially in the core. Engineers need special tools to insure that the core will resist the worst conditions. Most of the models developed for industrial purpose account for the damping and ad

This paper presents results from two ongoing European experimental programs on molten core concrete interactions: HECLA at VTT and VULCANO at the Commissariat a l'Energie Atomique. In the HECLA experiments, metallic melt is poured into a cylindrical

Three two-dimensional Molten Core–Concrete Interaction tests have been conducted in the VULCANO facility with prototypic oxidic corium. The major finding is that for the two tests with silica-rich concrete, the ablation was anisotropic while it was

Two experiments have been performed in the VULCANO facility in which prototypic corium has been spread over concrete. In the VE-U7 test, a mixture representative of what can be expected at the opening of EPR reactor-pit gate has been spread on silice
