DescriptionWe have launched a new research program since 2011 for the evaluation of fission product and actinide release behaviour under the severe accident. Chemical forms of fission products were focused on for more accurate evaluation of source term issues. This report describes the progresses and achievements of the research program in 2013. In order to clarify the Cs and I chemistry in the BWR system during the severe accident which include moderator material B4C, the three research items were configurated: the fission product release kinetics evaluation, the fission product chemical form evaluation and fundamental data acquisition. Basic knowledge on the chemistry of B4C and CsI have been obtained by using non-radioactive samples.
