| Research Abstract |
This study is for developing technology to dispose radioactive waste, especially for low-level radioactive wastes disposal that is most urgent. In this study, swelling pressure and swelling deformation properties of bentonite as barrier materials were investigated by experiment. Experiment condition was coexisting condition with concrete materials in disporsal facility. As a result, database for specification of bentonite buffer was produced. And theoretical method for practical evaluation to specification such as selection dry density, size and materials was proposed.
