Geoscientific studies at the Tono mineand the Kamaishi mine in Japan

Power Reactor and Nuclear Jhuel Development Corporation is conducting geoscientific studies to build a firm scientific basis for the safe disposal of high level radioactive waste in deep geologic formation. In this connection, the in-situ experiments have been carried out at the Tono mine and the Kamaishi mine. Comprehensive information on rock mechanical, hydrological and geochemical properties have been obtained at these sites, and the techniques and instruments for investigation of geological environment have been applied and the issues to be studied further have been identified. This paper describes the current status and future plan of the in-situ experiments at the Tono mine and the Kamaishi mine. Power…
