Japanese Ice Wall To Stop Reactor Leaks

Japan is planning to install a two-mile, subterranean ice wall around the Fukushima nuclear plant. ‘The ice wall would freeze the ground to a depth of up to 30 meters (100 feet) through a system of pipes carrying a coolant as cold as minus 40 degrees Celsius (minus 40 Fahrenheit). That would block contaminated water from escaping from the facility’s immediate surroundings, as well as keep underground water from entering the reactor and turbine buildings, where much of the radioactive water has collected.’

The technology they’re using has not been used to that extent before, nor for more than a couple years. An underground water expert said, ‘the frozen wall won’t be ready for another two years, which means contaminated water would continue to leak out.’ But at least they have a $470 million plan ready to present to the Olympic committee choosing between Madrid, Istanbul or Tokyo.
