    Abstract

    Research on source term has been ongoing for several years all over the world. This paper shortly synthesizes the recent main outcomes from source term research. It highlights knowledge gaps remaining and discusses ways to proceed to address those considered high priority. Fission product release under oxidizing conditions and/or from fuel configurations other than rod-like MOX are highlighted, particularly for MOX fuel. Transport through the circuit needs further research on high temperature chemistry and on processes resulting in a late in-containment source term, like revaporization. Needs regarding containment issues seem to be well addressed in forthcoming projects under the OECD framework (i.e., BIP3, THAI3 and STEM2) and the only open issue left out would be pool scrubbing, which is being partially tackled within the EU-PASSAM project. A similar situation to the containment exists in the source term mitigation area, in which the EU-PASSAM and the French national MIRE projects are underway. Aside from further knowledge-driven research, there is a consensus on the need to assess the source term predictability of current system codes and to build up an international experimental platform that contributes to keep the current research capability.
