Seawater injection into 'discharge tunnel' of treated water from Fukushima nuclear power plant completed

NHK reported on June 6th that "the work of injecting seawater into the undersea tunnel used to release radioactively treated water from the Fukushima Daiichi Nuclear Power Station into the ocean has been completed."

On the 5th, TEPCO began work to inject about 6,000 tons of seawater into the undersea tunnel from both land and sea, and the work was completed in the morning of the day. Once the heavy excavation equipment used for the tunnel construction is collected, the tunnel construction will be completed.

On April 25th, Tokyo Electric Power Company completed excavation of a submarine tunnel with a length of about 1,030 meters. Treated water is discharged into the sea through this undersea tunnel.

TEPCO will begin construction work just before sending treated water to the undersea tunnel, and plans to complete all construction work by the end of June.

On the other hand, the Japanese government is said to start releasing treated water into the ocean from this summer.
