Japan Moves to Fund 'Ice Wall' Around Fukushima

With dangerous radioactivity continuing to plague Fukushima Dai-ichi, Japan is preparing to make good on plans to build a wall of ice around the plant. The country will spend some $473 million on the project, which involves piping coolant through walls of frozen soil surrounding the plant. That should keep groundwater separate from radioactive water, of which there is plenty: An additional 400 metric tons of the stuff are created daily as part of the reactor cooling process. Meanwhile, the plant's water treatment equipment will undergo improvements, the BBC reports.
