TLDR
In this paper, the effect of fuel/coolant initial conditions and mixing on explosion energetics was examined using 3 kg of prototypical corium, which was poured into a water column of ≤ 1.25 m in height (95 and 200 mm in diameter) under 0.1 MPa ambient pressure.About:

Characteristics of Corium Debris Bed Generated in Large-Scale Fuel Coolant Interaction Experiments
TL;DR: In this paper, the formation of corium debris as the result of fuel-coolant interaction (energetic or not) has been studied experimentally in the FARO and KROTOS facilities operated at JRC-Ispra between 1991 and 1999.
Journal ArticleDOI
Results of recent KROTOS FCI tests : Alumina versus corium melts
TL;DR: In this article, it was shown that the water depletion in the mixing zone suppresses steam explosions with corium melts at ambient pressure and in the present pour geometry, however, propagating low energy (about twice the energy of the trigger pulse) events were observed.

Insight into steam explosions with corium melts in KROTOS
I. Huhtiniemi,D. Magallon +1 more
TL;DR: In this article, the authors describe two KROTOS tests in which ∼4 kg of corium melt was injected into a ∼1-m deep subcooled water pool and showed that the corium jet penetrated deep into the water while maintaining its shape.

Corium melt quenching tests at low pressure and subcooled water in FARO
D. Magallon,I. Huhtiniemi +1 more
TL;DR: The first two corium melt quenching tests in subcooled water performed in the FAT FCI vessel of the FARO facility are described in this article, which involved 39 and 92 kg of 80 wt% UO 2 + 20 wt % ZrO 2 melt, respectively.

Yuzuru Iwasawa,Yutaka Abe +1 more
TL;DR: In this paper, a review summarizes experimental works on the fuel-coolant interaction (FCI) phenomenon, especially, fragmentation of a melt jet during a severe accident in an NPP, and special attention is paid to solidification effects.

Fragmentation and quench behavior of corium melt streams in water
TL;DR: In this paper, a series of six experiments (designated CCM-1 through {minus}6) were performed in which molten corium passed through a deep pool of water in a long, slender pour stream mode.
Journal ArticleDOI
FCI experiments in the aluminum oxide/water system
TL;DR: In this paper, the authors used the KROTOS facility at JRC Ispra to study experimentally melt-coolant premixing and steam explosion phenomena in Al2O3/water mixtures with approximately 1.5 kg melt at 2300-2400 °C.

Experimental investigation of 150-kg-scale corium melt jet quenching in water
D Magallon,H Hohmann +1 more
TL;DR: In this paper, the results of two large scale FARO quenching tests known as L-11 and L-14, which involved respectively, 151 kg of 76.7 wt.% UO 2 +20 ZrO 2 melts poured into 600-kg, 2m deep water at saturation at 5.0 MPa.
Journal ArticleDOI
Premixing-related behavior of steam explosions
TL;DR: In this paper, the results of these analyses are shown to provide quantitative interpretations of the data, and to suggest conditions/measurements in further experiments to enhance the insights obtained, and a quantitative radiography technique is described and applied to Magico for the measurement of chordal-averaged void fractions in the mixing zone.
