Japan Building $470M Ice Wall

    Japan's Economy, Trade and Industry Minister Toshimitsu Motegi (C), wearing a protective suit and a mask, inspects at the tsunami-crippled Fukushima Daiichi nuclear power plant in Fukushima prefecture August 26, 2013, in this photo released by Kyodo. Tokyo Electric Power Co , the operator of the stricken Fukushima nuclear plant, said it would invite foreign decommissioning experts to advise it on how to deal with highly radioactive water leaking from the site, and Japan signalled it may dip into a $3.6 billion emergency reserve fund to help pay for the clean-up.

    It’s expensive, but will it work? Japan announced plans to spend a half billion dollars to build a subterranean wall of ice to control radioactive water leaks from the Fukushima nuclear plant. The site has been leaking hundreds of tons of contaminated water since the 2011 earthquake and tsunami that damaged its cooling towers and melted three of its reactors. The proposed wall of frozen earth will be made of pipes filled with coolant in hopes of preventing the ground water from being contaminated by radioactive water used to cool the reactors, 300 tons of which leaked from the temporary storage tanks just last month.
