"Work started June 2 on a 32-billion-yen ($314 million) project to build an underground frozen wall at the stricken Fukushima No. 1 nuclear plant to address a chronic problem plaguing work at the site.

The plan is for the wall of frozen soil to divert groundwater into the ocean and prevent it from seeping into reactor buildings and becoming contaminated by radiation.

But given the enormity of the project--unprecedented in terms of scale and period of use--numerous risks and potential hazards exist."

The Asahi Shimbun had the story June 3, 2014. [2]
