Highly radioactive water from Japan's crippled Fukushima nuclear plant is pouring out at a rate of 300 tonnes a day, officials said on Wednesday, as Prime Minister Shinzo Abe ordered the government to step in and help in the clean-up.
The revelation amounted to an acknowledgement that plant operator Tokyo Electric Power Co (Tepco) has yet to come to grips with the scale of the catastrophe, 2 1/2 years after the plant was hit by a huge earthquake and tsunami. Tepco only recently admitted water had leaked at all.
Calling water containment at the Fukushima Daiichi station an "urgent issue," Abe ordered the government for the first time to get involved to help struggling Tepco handle the crisis.
The leak from the plant 220 km (130 miles) northeast of Tokyo is enough to fill an Olympic swimming pool in a week. The water is spilling into the Pacific Ocean, but it was not immediately clear how much of a threat it poses.
