On the morning of the 28th, TEPCO began releasing the treated water that has accumulated at the Fukushima Daiichi Nuclear Power Plant into the ocean for the fourth and final time this fiscal year.
In August of last year, TEPCO began diluting the treated water containing radioactive substances such as tritium that remains after treating contaminated water to a concentration below standards and releasing it into the sea. It releases 3351 tons.
At around 11:10 a.m. on the 28th, TEPCO began the last of the four planned releases for this fiscal year.
Approximately 7,800 tons are scheduled to be released by the middle of next month.
There have been no notable problems with the releases so far, and the tritium concentration in the seawater sampled around the nuclear power plant is well below the standard for TEPCO to voluntarily decide to stop the release.
However, during the process of treating contaminated water, a worker was temporarily hospitalized in October last year after being exposed to waste fluid containing radioactive materials, and on the 7th of this month, water containing radioactive materials leaked from a contaminated water purification system. is happening.
At a meeting held on the 27th among fishermen's cooperatives in Fukushima Prefecture, concerns were voiced over the way the work was being carried out, and TEPCO's safety management is now under scrutiny from the local community.
