Last month, it was decided that the treated water containing radioactive substances such as tritium stored at the Fukushima Daiichi Nuclear Power Station would be diluted to a concentration below the standard and then released into the sea, but TEPCO has decided to use it for storage. Announced that a part of the tank will be diverted to a tank for checking the concentration before discharge.
This is the first time that concrete preparations for ocean release have been explained.
The treated water, including tritium continue to accumulate in the Fukushima Daiichi nuclear power plant, the government last month, after diluted to concentrations below the standard, we decided to release to the sea after two years in prospect.
Regarding this, TEPCO has converted about 30 tanks for 30,000 tons of the 1000 treated water storage tanks into preparation tanks for checking the concentration of tritium and other radioactive substances before release. Announced that it will be diverted.
We plan to install a pump that stirs water when water is temporarily stored, such as while waiting for measurement results.
On the other hand, in order to make up for the 30,000 tons that have been diverted, it is said that about 20 new storage tanks will be added.
In addition, a photograph of the upper part of the huge concrete lid and containment vessel called the shield plug was released for the camera survey of the upper part of the Unit 2 reactor building conducted this month.
TEPCO said that the investigation confirmed the contamination again, but that no major damage was found.
