A Japanese project to freeze soil around the decommissioned Fukushima nuclear plant into a giant ice wall has been activated. The wall is designed to stop the spillage of dangerous radioactive water that has been occurring since the plant was damaged in the Japanese earthquake and tsunami of 2011. The government-funded project has taken two years to complete and has cost £218 million. An ice wall will be formed in the coming months as pipes inserted 30m underground will freeze the soil around them.
