The discussions on scientifically promising site for the geological disposal has been made at the council of studying group on techniques for geological disposal of radioactive wastes, which is held by Resources and Energy Agency. From the aspect of ensuring safety during the transportation of disposal waste, the coastal area is discussed to be a more suitable area. This report shows the result of the first year of this project as following items; Study on the state-of-art technology and remain tasks; laboratory tests on characterization of colloidal silica grout under sea water; Study on the development of grouting technology (design and the evaluation method of influence on the rock mass).

The amount of the information such as the data, models and analysis results related to geological environment has been enormous. It is believed that an appropriate organization of the information is useful for conducting geological environment survey work at the candidate sites of geological disposal. The Survey on Geological Disposal Technology projects commissioned by METI that started in FY2015 handles various information such as the data, models, analysis results, etc. of geological environment. In this project, in preparation for collection and compilation of the information on geological environment in coastal areas, we have made clear the current status of the existing systems including databases. At the same time, we have created measures for centralized information management for the purpose of organizing a huge amount of information as well as sharing the information and information management systems among the related organizations.
