N2 - Because buffers for disposal of high-level radioactive wastes must have high swelling characteristics for sealing wastes, bentonite is currently designated for that use. High-level radioactive wastes generate decay-heat, and it is has been inferred that the swelling characteristics of bentonite decline because of the decay-heat of wastes. This study investigated swelling pressure and swelling deformation of bentonites during some thermal experiments conducted in the laboratory. Moreover, this study discusses the mechanism of thermal influences to bentonite-swelling by considering the above experimentally obtained results with chemical analyses such as measurement of cation concentration of water around the specimen, a methylene blue absorption test, and X-ray powder method for heated bentonites.
