Yesterday (5th) TEPCO started pouring around 6,000 tonnes of seawater into the submarine tunnel from the land and sea near the Fukushima nuclear power station, and finished the work this morning (6th).
When the heavy mining equipment used for the construction of an undersea tunnel is recovered, the tunnel construction is completed.
Previously, TEPCO completed the excavation of an undersea tunnel about 1030m long on April 25, and the contaminated water is expected to be discharged into the sea in front of the nuclear power plant through the undersea tunnel.
TEPCO plans to complete all construction work for the discharge of contaminated water from the ocean by the end of this month after completing the construction of the tank to store the contaminated water immediately before it is sent to the tunnel undersea
The Japanese government plans to start dumping contaminated water into the ocean this summer.
An International Atomic Energy Agency (IAEA) investigative team visited Japan last week to complete a comprehensive verification process, and is expected to release a final report sometime this month before Japan releases the contaminated water.
