Title: Fukushima Daiichi Nuclear Power Plant Start of marine soil coating construction inside the port
Source: Tepco Handout
Date: Feb 21, 2012

According to past sampling, we detected relatively high concentrated radioactive materials from marine soil sampled at inside of the port. Since the marine soil will be spread by ocean wave, we plan to prevent spreading of marine pollution to outside of the port by covering marine soil with solidified soil. [...]

・We will use solidified soil made from bentonite and cement as covering material since it doesn’t affect to coastal environment and has less variability of quality of construction.
・For lower layer, we will use light weight solidified soil (Coating material A) to cover high natant floating mud of seafloor surface
・For upper layer, we will use solidified soil (Coating material B) which has superior durability and easiness to fill
