» Construction of underground ice wall gets go-sign by NRA

The Nuclear Regulation Authority said that it will allow TEPCO to begin construction of an underground ice wall at the Fukushima Daiichi nuclear complex in June as planned, after dispelling a key safety concern.

The frozen wall, to be set up around the buildings housing the Nos. 1 to 4 reactors hit by the 2011 nuclear disaster, is seen as an important measure to address the buildup of radioactive water at the complex.

NRA has been wary of the impact of ground sinking that may occur in implementing the project, but it accepted TEPCO’s explanation the same day that tilting of the ground supporting the reactor and adjacent turbine buildings will not be significant enough to undermine safety.
