Giant barge to store radioactive water from Japan nuclear plant

A giant barge which will be used to store radioactive water from the damaged Fukushima nuclear plant has left Yokohama harbour.

The 35ft (11m) tall basement in the number 1 reactor building is almost half-full with water - an estimated 3,000 tonnes, more than in an Olympic swimming pool.

The giant barge is 446ft (136m) long and 151ft (46m) wide, and according to local media can hold a maximum of 10,000 tonnes of water.

The platform, which was originally used as a floating island by local fishermen, is expected to reach the plant sometime near the end of May.
