It is essential to understand the properties of fuel debris for implementation of various countermeasures related to fuel debris retrieval and storage management at the Fukushima Daiichi Nuclear Power Station (1F). The step-by-step retrieval and property analysis are planned in the future. Especially, the chemical analysis is needed for chemical composition information but fuel debris is considered to be insoluble due to the occurrence of melt core-concrete interaction. Therefore, the establishment of chemical analysis method is an key issue. In this research, to establish suitable dissolution methods as well as separation and analysis processes is planned by using Inductively Coupled Plasma Mass Spectrometry which has been applied in the field of radiochemistry in recent years. In this presentation, we will introduce the outline of the implementation and the collaborative laboratories established at JAEA and Tohoku University as a place for human resource development.
