Abstract

A high-level radioactive waste disposal facility might be built in a coastal area of Japan to facilitate transportation of radioactive waste. This study investigates the influence of seawater on the self-sealing capability of a bentonite-based buffer. It also investigates the change of compositions of exchangeable cations such as Na + and Ca 2+ in a bentonite-based buffer before and after self-sealing to clarify infiltration/filtration mechanisms of seawater cations into bentonite.
