Japan says it plans to build an "ice wall" around the Fukushima nuclear plant to stop radioactive water from spreading further. But critics say there are environmental and political risks to such a move. We discuss the efforts to control the leaks, and look at how the radioactive waste might affect the West Coast of America.
