• The nearly mile-long structure consists of underground pipes designed to form a frozen barrier around the crippled reactors.
• The $312 million system was completed last month, more than a year behind schedule.
• Nearly 800,000 tons of radioactive water are already being stored onsite.
Japanese authorities have activated a large subterranean “ice wall” in a desperate attempt to stop radiation that’s been leaking from the Fukushima Daiichi nuclear power plant for five years.
Construction of the $312 million government-funded structure was completed last month, more than a year behind schedule, the Associated Press reports. The nearly mile-long barrier is intended to block groundwater from entering the facility and becoming contaminated.
