TEPCO starts pumping to prevent water leak
The operator of the Fukushima Daiichi nuclear power plant has begun pumping up radioactive groundwater there to keep it from flowing into the sea.
Tokyo Electric Power Company dug a small well near an embankment facing the sea and began the pumping at about 2 PM on Friday.
The pumped-up water is moved to an underground trench and then stored in tanks in the plant's compound.
The utility has hardened soil near the embankment since last month to prevent tainted groundwater from seeping into the sea.

TEPCO knew about water flow two years ago
A spokesperson for Tokyo Electric Power Company says the company has known for the past 2 years that a massive amount of groundwater was flowing beneath the Fukushima Daiichi power plant.
Masayuki Ono said on Friday that TEPCO experts estimated hundreds of tons of the water could reach the ocean daily.
Ono said the estimate was based on rough records of groundwater that TEPCO workers had collected.
Until last month, TEPCO officials had denied the possibility that contaminated groundwater was leaking into the ocean.
Ono said he is unable to explain why it took two years to disclose this fact.

TEPCO:Underground wall not effective against leaks
The operator of the damaged Fukushima nuclear power plant has confirmed that an underground wall is unable to keep contaminated groundwater from seeping into the sea.
Officials of the Industry Ministry estimate that 300 tons of groundwater pass through the contaminated area before flowing into the Pacific Ocean every day.
Engineers with Tokyo Electric Power Company have hardened the soil along the coast to create a 100-meter-long underground wall.
They injected chemicals into the ground to a depth of 16 meters. But it is technically difficult to harden the soil up to 1.8 meters from the surface.
The workers recently dug a well just inside the wall to see how the level of underground water has risen due to the construction of the wall.
They found that the water level in the well was about 60 centimeters higher than the top of the wall.
The operator began pumping up contaminated groundwater on Friday, as a temporary measure to lower the water level.

Is Japan discharging contaminated water or can't stop the leakage ?
