Research on advanced technology of performance assessment and monitoring for geological disposal of high-level radioactive waste (Joint research)

Geological Isolation Research and Development Directorate; Advanced Waste System Research Project, Radioactive Waste Management Funding and Research Center*

JAEA and RWMC have carried out a joint research program on advanced technologies that could be used to support performance assessment and monitoring of geological disposal concepts for high-level radioactive waste. The 5 items regarding to performance assessment and 1 item for monitoring were considered in the program. The items were discussed in the context of technological experiences gained by JAEA and RWMC in previous repository-related studies. According to the results of these discussions, development strategies for each of the technology areas identified above were efficiently formulated by appropriate task allocations. Specific technical subjects requiring further investigation were identified using this approach, and a priority of subject was also discussed.
