Title: Commencement of Water Shielding Wall Construction
Source: Tepco Press Release
Date: Apr 24,2012
The water shielding wall will be installed in front of the existing seawalls of Units 1 to 4 to prevent further contamination of the ocean due to the leakage of ground water, for which we have conducted preparatory including geological survey per measurement and boring inspection thus far.
(Previously announced on October 26, 2011)
As a license to landfill publicly-owned seawater surface is required to install the water shielding wall, we have applied for the license to Fukushima Prefecture on February 7, 2012. Since the necessary investigation procedures have been finished and the license was issued by Fukushima Prefecture on April 20, 2012, we will start construction of the water shielding wall from April 25.

Even though we are making utmost efforts to prevent the water accumulated within the buildings of Units 1 to 4 from leaking into the groundwater, we are planning to install a water shielding wall of steal sheet pile having enough impermeability in front of the existing seawalls of Units 1 to 4, just in case of the accumulated water leaking in to the ground water to prevent further contamination of the ocean.
