Accident at a nuclear power plant Fukushima Daiichi TEPCO, which interferes with work to restore the cooling process water contaminated with radioactive material high concentrations, and inspection of facilities to which to transfer water, water and lay the hose ready to send, it takes longer than expected, the work has been difficult.The primary Fukushima Daiichi is found in large quantities of water contaminated with radioactive material concentrated from the tunnel, called a trench and turbine building, they also become a cause out the amount of high radiation interfere with the work towards the restoration of cooling making.These high levels of contaminated water is believed to have at least 5 million tons, TEPCO policy for the premises to be among them, can earn about 30,000 tons of water waste treatment facilities focus offers preparing to connect the hose from the turbine building.Possible to reduce exposure of workers is scheduled through the hose of a turbine building each floor, 30 cm diameter holes to pass the hose, according to five locations, the walls of the building that was opened It is.However, some of the building is also likely to be a high radiation dose where the work will also lay the hose is not yet started, which sends polluted water waste treatment facilities focus because it also requires inspection of drainage work is not progressing.On the other hand, the level of high levels of contaminated water trapped in trench No. 2, since the stopped flow to the sea, they raised 11 inches by the evening of April 9, the height from the ground surface to the 93 cm and is at 6 pm on April 9.TEPCO, the policy of discharging water from contaminated water first trench No. 2, we can begin to transfer the water to the condenser also April 10.
