Ishihara, Yoshinao*; Fukui, Hiroshi*; Sagawa, Hiroshi*; Ito, Takaya*; Matsunaga, Kenichi*; Kohanawa, Osamu*; Kuwayama, Yuki*

The present study was carried out relating to basic design of the "Geological Disposal Technology Integration System" that will be systematized as knowledge base for analysis and assessment of geological disposal by integrating organically and hierarchically analysis and evaluation method in three study field. The key conclusions are summarized as follows: (1)The examination to construct the virtual geological disposal system which contained the geological environment on the computer was executed aiming at the development of integration and the analysis systems which became working common basic to execute the design and the performance assessment of the geological disposal system. (2) Technological information (I/O information) which became the base was associated with work (evaluation) item of "Disposal technology (design)" and "Performance assessment" in the Second Progress Report by JNC, and the evaluation flow by which a series of work concerning the design and the safety assessment of the geological disposal system was brought together was made. (3) The subject concerning the detailed model development in the R&D activity of the geological disposal system in the future was extracted aiming at the systematization of the performance and safety assessment, and was arranged as information to take these detailed models into the "Geological Disposal Technology Integration System".
