TEPCO has begun maintenance work on the exit of a new submarine tunnel to dilute the treated water containing radioactive substances such as tritium that continues to accumulate at the Fukushima Daiichi Nuclear Power Station to a concentration below the standard and then let it flow into the sea. Did.
TEPCO plans to construct a new undersea tunnel about 1 km offshore from the Fukushima Daiichi nuclear power plant in order to release the treated water to the sea. Announced that it started.
On the 25th, four signs indicating the construction area were set up on the sea, and weights for mooring work vessels were set up at three places in the harbor.
Also, from the 27th, it is said that the work of digging the seabed of the outlet by about 11 meters and smoothing the bottom will start.
TEPCO is currently installing a facility called a "vertical shaft" on the east side of Units 5 and 6 to store treated water in advance for release to the ocean, but this is the first construction on the sea side. ..
TEPCO wants to start full-scale construction such as the construction of the tunnel body from around June if the plan is approved by the Nuclear Regulation Authority and the consent of the locals is obtained, but mainly fishermen. There are deep-rooted concerns about the damage caused by rumors, and the issue is how the government and TEPCO will gain the understanding of the parties concerned.
