Record-high tainted water leak at Fukushima plant
The operator of the Fukushima Daiichi nuclear plant says 100 tons of water containing record high levels of radioactive substances overflowed from a storage tank.
Tokyo Electric Power Company officials on Thursday said workers on patrol found the leak in one of the tanks located on the mountain side of the Number 4 reactor building late Wednesday night.
They said the leaked water contained an extraordinarily high 230-million becquerels per liter of beta-ray emitting substances, consisting mainly of strontium 90.
The level is about 7.6 million times the government's permissible standard for the nuclide level of water allowed to be released into the sea.
It is also the highest level of radioactive substances detected so far in the series of tank leaks at the site.
They say they also detected 9,300 becquerels per liter of cesium 137 in the water. That is more than 100 times the government's limit.
They say the water was leaking from a seam near the top of the tank. It traveled along a rainwater pipe that extends to outside the barrier surrounding the tank.
Officials say they managed to stop the leak by transferring water from the overflowing tank to a neighboring one, 6 hours after the problem was first discovered.
The utility estimates that about 100 tons of water had flowed outside the barrier. But they say the water should not have flowed into the ocean because there are no spillways near the tank that lead to the sea.
Utility officials attribute the leak to a fault in one of the valves in the pipes that transfer water from a decontamination system to storage tanks.
They say 2 other adjoining valves that lead to the troubled tank were open, leading to the unexpected flow of water into the tank and causing an overflow.
They say an alarm had gone off earlier in the day, signaling an increase in the tank's water level. But workers who went to check the tank could find no abnormalities at that time.
Officials say they are continuing their investigation, while working to recover the leaked water and the surrounding soil now contaminated by the water.
The Nuclear Regulation Authority has instructed TEPCO to check other tanks for possible leakages.
