On the morning of the 27th, TEPCO began a survey to understand the conditions of the seabed, with the aim of constructing a submarine tunnel to release treated water containing radioactive substances such as tritium, which continues to increase at the Fukushima Daiichi Nuclear Power Station.

The investigation began at 6 am on the 27th, and two work vessels were set off about 1 km offshore from the Fukushima Daiichi nuclear power plant.



This sea area is a planned area for boring surveys for the construction of undersea tunnels, and in addition to magnetic exploration using sensors, visual surveys by divers were also conducted to investigate whether there were any obstacles. is.



According to TEPCO, the work on the 27th will be completed after 4 pm, and the magnetic exploration will be conducted until the 28th.



The boring survey is scheduled to begin on the 1st of next month at the earliest.



Regarding the ever-increasing amount of treated water at the Fukushima Daiichi Nuclear Power Plant, the government plans to dilute it to a concentration below the standard and then drain it into the sea by the spring of 2023. Shows the plan.



On the other hand, regarding the release of treated water to the sea, there are deep-rooted concerns about the damage caused by rumors, and the issues are how to gain the understanding of the people concerned and effective measures against rumors. It has become.
