Several numerical models have been prepared to deal with various time- and spatial-scale issues related to radioactive cesium migration in environment in Fukushima area. This paper describes fragments of the JAEA's approaches of modeling to deal with the issues corresponding to radioactive cesium migration in environment with some case studies.

JAEA has initiated research and development of spent fuel direct disposal in FY 2013. In the research and development so far, we were able to construct approaches for design and safety assessment and to present the disposal concept based on multi barrier system as well as the technical level of the direct disposal, through carrying out the preliminary design and safety assessment, by taking characteristics of geological environment in Japan and the spent fuels into consideration. In addition, challenges/issues related to the design and safety assessment to be addressed towards the research and development in the next stage, were identified, classified and organized. In the future, we are going to present the technical reliability of the direct disposal by resolving the challenges/issues.
