Fukushima reactor 'ice wall' nearly finished

Fukushima reactor 'ice wall' nearly finishedFukushima’s operator on Tuesday started freezing the last section of a $ 320 million ice wall designed to combat widespread water contamination at the site of the worst nuclear accident in a generation. Tokyo Electric Power (TEPCO) began pumping coolant into the remaining seven metres (23 feet) of its 1.5-kilometre underground wall which encircles the four reactors along Japan’s northeast coast. The 30-metre deep wall is designed to block underground water from nearby mountains from flowing into the shattered complex and then seeping into the Pacific.
