We have been considering water shield walls to prevent further seawater 
contamination by underground water, and plan to start construction during 
the Step 2 period, as we announced in the press release "Pre-installment 
of Water Shield Wall at the Seaside" on August 1, 2011. 

We announce that we have put together the basic design of water shield 
walls to prevent further seawater contamination by underground water.

We will conduct further study and plan to start construction during the 
Step 2 period.
