The Fukushima nuclear plant could be buried in concrete

The solution from Chernobyl could eventually be applied at Fukushima.

Two of the largest concrete pumps in the world will be sent next week from the United States to Fukushima. They will be transported on board the world's largest cargo plane - the Antonov 225.

Each pump can pour out 160 cubic meters of concrete per hour. Another two somewhat smaller pumps are already on their way (Vietnam and Germany) towards Tokyo.

At first, the pumps will be used in a final attempt to cool the reactors. However, if the operation fails, the reactors will most probably be covered with concrete.
