The Fukushima Daiichi nuclear plant’s operator on Tuesday started freezing the last section of a 35-billion yen ($320 million) ice wall designed to cut down on vast amounts of contaminated water at the site of the worst atomic accident in a generation.
Tokyo Electric Power Co (TEPCO) began pumping coolant into the remaining seven meters of its 1.5-kilometer underground wall which encircles four reactors along Japan’s northeast coast.
Underground pipes circulate the coolant and freeze soil around the buildings.
The 30-meter-deep wall is designed to block underground water from nearby mountains from flowing into the shattered complex and then seeping into the Pacific.
