OREANDA-NEWS. August 02, 2011. As announced in "Roadmap towards Restoration from the Accident at Fukushima Daiichi Nuclear Power Station" on July 19, 2011, we are in consideration of water shield wall to prevent further seawater contamination by underground water, and to start construction during the Step 2 period, reported the press-centre of TEPCO.

We have now decided to pre-install water shield wall in front of the existing sea walls of Unit 1 to 4, to prevent further seawater contamination by underground water.

We will compile the design in an early stage, and start construction within the Step 2 period.
