The most relevant open questions combined with activity release during hypothetical core meltdown accidents refer to the chemical behavior of the highly reactive elements iodine, cesium, and tellurium, to the release characteristics of the medium-volatile fission and activation products, to the properties of the resulting aerosol particles, and to various phenomena during steam explosion and melt/concrete interaction. To answer some of these questions, experiments are conducted at the melting facility SASCHA in which a representative core material mixture (corium) is induction-heated to temperatures of 3000 K. The released material is analyzed by use of gamma-ray spectrometry and electron scanning microscopy. Some results of the first series of experiments in air are given below:
