Japan has plans to build a wall which will freeze the soil under the Fukushima plant to slow down the radioactive water buildup. The Tokyo Electric Power Co (TEPCO) will begin constructing the structure this month. 

The project, which is being funded by the government, will use pipes in the soil to circulate refrigerant. They will ultimately build a 0.9 mile wall to slow the influx of water flowing from underneath the plant, where it mixes with the polluted water used to cool reactors. 

"We had some concerns, including the possibility that part of the ground could sink," an anonymous official told PhysOrg. "But there were no major objections to the project during the meeting, and we concluded that TEPCO can go ahead with at least part of the project as proposed after going through further necessary procedures."

A similar procedure has been used before during the construction of tunnels near watercourses, but nothing of the size or time frame TEPCO has proposed.
