In this report, we sophisticated the framework as a part of the total system performance assessment for two purposes: the first one is quantification of relationship of characteristic of natural phenomena between geological environmental conditions (THMCG), and the other one is quantification of relationship of THMCG condition between parameters of performance assessment. On the other hand, we applied the sophisticated framework to all natural phenomena. As a result, to apply the sophisticated framework, we could show that information integration could carry out efficiently. Moreover, we have checked that the framework was applicable to all phenomena. Furthermore, we could show that suitable scenarios might be chosen by information integration.

The method contributing to the improvement of confidence and the systematization of the various information and knowledge under the responsibility of each researcher has examined. As a result, "a systematic compilation method to exhibit the level of the confidence on the assessments" has been developed based on the approach of the international quality management system. It is possible to manifest the aims, intention, contents, approach and process of the study by compiling and presenting the results of the studies using this method. In addition, transparency and traceability would be shown and the adequacy of the obtained result would be claimed by researcher through the conformity assessment for the result of the study. These results would contribute the understanding of reader and improvement of confidence.

Development of advanced JGIS considering quality management and project management

The investigation and studies of site-specific geological conditions provide much information and data. A system for managing and integrating the technical information was developed (JGIS: JAEA Geological Disposal Information Integration System). In this study we built the conceptual design in order to implement the function of quality management and project management to JGIS. We considered that researchers could access the portal site of the research projects which were set as the WBS (Work Breakdown Structure) items and could confirm which WBS item the research project belonged to in the whole plan. We also considered that the research projects could be managed by using the conformity sheets which were adopted in the quality management system.

This report is to outline a 5-year plan of research and development (R&D) for performance assessment of potential effect of natural phenomena on a geological disposal of high-level radioactive waste in JAEA. In each research plan, objectives based on the necessity and the significance of the research plan are clarified in the section of "Objectives and the past progresses", with summarizing the progresses of H12: Project to establish the scientific and technical basis for HLW disposal in Japan (Second Progress Report), and H17: Development and management of the technical knowledge base for the geological disposal of HLW (H17 report). In addition, next five year plan is described in the section.

no journal, , 

We showed the concept of the total system performance assessment. Based on the concept, we examined and integrated information about the significant impact of the natural phenomena exerted on geological environment conditions and HLW disposal system environmental condition for groundwater scenarios.
