“…In the second group, we find Te, Ru and Sr, characterized by intermediate incorporation energies. Ru and Sr are known to be semi-volatile [36], i.e. their release rate at high temperatures is related to compounds vaporization at grain boundaries.…”

“…For a given fuel (e.g., comparing V4 and V5), barium is more released under reducing conditions whereas molybdenum is more released under oxidizing conditions. Ruthenium shows very extreme variations [4]. On one hand, ruthenium is a low volatile fission product and it is only slightly released under reducing and low oxidizing conditions (<10%).…”

“…Presently, there are several on-going experimental and analytical programs about source term issues. For instance, the VERDON program [14] focuses on Ru behaviour in a reactor especially at the time of air ingression in a severe accident scenario under the framework of the Severe Accident Research NETwork of Excellence (SARNET) [15].…”

Research Program for the Evaluation of Fission Product and Actinide Release Behaviour, Focusing on their Chemical Forms

We have launched a new research program for evaluation of fission product and actinide release behaviour under severe accident conditions, focusing on their chemical forms. In this research program, the fission product and actinide release models incorporated in the severe accident analysis code will be improved by implementing effects of chemical forms that are to be obtained by an experimental investigation on the fission product and actinide release behaviour from irradiated fuels. A novel insitu measurement method of chemical forms of fission products and actinides just after their release as well as an off-line analysis method will be employed as the experimental means for evaluating the chemical forms at the release and their stability after release.
