||Significance of international cooperative research on fission product behavior towards decommissioning of Fukushima Daiichi Nuclear Power Station; Review of the CLADS International Workshop
17 , 2016-07 , JAEA
The severe accident (SA) of Fukushima Daiichi Nuclear Power Station (1F) has given rise to enlarged research needs for the improvement of the source term assessment. Fission Product (FP) related researches, however, have not been widely conducted in Japan for many years, thus a framework for such research is not so robust. The Collaborative Laboratories for Advanced Decommissioning Science (CLADS) workshop held in November 2015 was an important opportunity to gain the state of art knowledge on FP and to start discussion between worldwide experts on innovative solution for 1F issues. This report describes the outcomes of FP session conducted in the CLADS workshop. It was pointed out during the workshop that further analyses were needed to properly understand the phenomena that occurred in 1F. The establishment of a Japanese FP platform is here proposed to respond to 1F issues effectively as a means to coordinate the national research efforts and increase communication between worldwide stakeholders. The FPs studies conducted in this frame will provide important information for the decommissioning of 1F, and will be also of great help for the international community to progress the knowledge on FPs behavior. Finally their outcomes could contribute in establishing improved SA management measures.
