The 2011 off the Pacific coast of Tohoku earthquake affected Japan, wreaking severe damage to the Nuclear Power Station in Fukushima. Heavy Bentonite-Based Slurry has been examined the use as filling-type water sealing materials in damaged nuclear reactors. This research was conducted to investigate and define the water stopping capabilities of Heavy Bentonite-Based Slurry for controlling the nuclear accidents. In this study, the falling head permeability tests were conducted to quantify it. The results show that the hydraulic conductivity decreased from k = 10 −8 m/s to k = 10 −10 m/s with sedimentation of specimens.
