Abstract

The first two corium melt quenching tests in subcooled water performed in the FAT FCI vessel of the FARO facility are described. The tests, referenced as L-29 and L-31, involved 39kg and 92 kg of 80w% UO2 +20 w% ZrO2 melt, respectively. The molten material was poured in a 1.5-m-depth pool of water at 0.2MPa and ambient temperature. No spontaneous steam explosion occurred. The quenching process was different between the two tests, producing a conglomerate debris bed in L-29 and a particulate debris bed in L-31, with higher thermal load in L-29 than in L-31. A difference in the melt initial temperature is believed to be the cause of this dissimilarity.
