About 12 tons of radioactive water has leaked at Japan's crippled Fukushima Daiichi nuclear power plant, with the facility's operator saying Thursday that some might have flowed into the Pacific Ocean.

crippled Fukushima Daiichi nuclear power plant, with the facility's operator

Ocean
.
Tokyo Electric Power Co. Inc. (9501.TO) said the leak was found early Thursday
from a pipe attached to a temporary decontamination system, and the water had
already gone through some of the cleansing process.
The water, once it has been used to cool the reactors, contains massive amounts
of radioactive substances and is put into the water-processing facility so it
can be recycled for use as a coolant.
"Our officials confirmed that cooling water leaked at a joint in the
pipes," a TEPCO spokesman said, adding that "it is possible that part
of the water may have flowed outside the facility and poured into the
ocean."
The leak has since been plugged, the spokesman said, saying the utility was
investigating the cause of the accident and how much, if any, water flowed into
the ocean.
The accident was the latest of several leaks of radioactive water at the
troubled plant, undermining the government's claim made in December that the
shuttered
Fukushima
reactors were now under control.
In one incident last month, about 120 tons of radioactive water leaked at the
plant's water decontamination system, and about 80 liters seeped into the
ocean, according to TEPCO.
The plant about 220 kilometers northeast of
Tokyo
was
crippled by meltdowns and explosions caused by
Japan
's
massive earthquake and tsunami in March last year.
Radiation was scattered over a large area and made its way into the sea, air
and food chain in the weeks and months after the disaster.
Tens of thousands of people were evacuated from their homes around the plant
and swathes of this zone remain badly polluted. The cleanup is proceeding
slowly, amid warnings that some towns could be uninhabitable for three decades.
