Japan Aims To Contain Nuclear Contamination With Wall Of Ice
Japanese officials are still battling radioactive groundwater that is leaking as a result of the Fukushima Nuclear plant meltdown triggered by the 2011 earthquake and tsunami.
The latest effort to block contaminated water from leaking into the Pacific Ocean is a $470 million ice wall. How do you build an ice wall and how does it work? Larry Applegate, the president of Seattle-based firm SoilFreeze, a company that creates frozen walls and tunnels, explains the technology to Marcie Sillman.
