Characteristics of corium debris beds formed in a severe coremelt accident are studied in DEFOR-S experiments, in which binary-oxidic simulant-material melts are discharged into a water pool. Water subcooling and pool depth are found to significantly influence the fragment morphology and agglomeration. The DEFOR-S data to date are indicative of the effect of melt composition, notably eutectic vs. non-eutectic. Synthesis of the DEFOR-S observations with respect to debris fragment's shape and surface roughness suggest the governing role of competitive mechanism: drop breakup, freezing and solid fracture.
