JAEA has promoted R&D on HLW geological disposal technology. JAEA launched the Mizunami and the Horonobe URL Projects to cover the diversity of geological environments in Japan. The Mizunami URL Project is a geoscientific research project in the crystalline rock environment. The Horonobe URL Project consists of geoscientific studies and R&D on geological disposal technology in the sedimentary rock environment. Both URL projects have been planned to proceed in three overlapping phases, Surface-based investigation Phase, Construction Phase and Operation Phase. Currently, the construction of research galleries in both of the Mizunami and the Horonobe URLs has been completed to 500 m and 350 m depths, respectively. JAEA will promote R&D activities in Phase III including study of the long-term evolution of the geological environment, and contribute to international cooperation, development of human resources and communication amongst stakeholders through both URL projects.

Study of hydrogeochemistry during construction, operation and closure of underground facility

Iwatsuki, Teruki; Saegusa, Hiromitsu; Onoe, Hironori

no journal, , 

Hydroceochemical change around Mizunami and Horonobe URLs were observed to understand hydrogeochemical impact caused by large-scale underground facility. The results show the change of groundwater pH, redox condition and the processes in excavation damage / disturbed zones.
