TEPCO has strengthened the survey of seawater, etc. conducted in the waters around the Fukushima Daiichi Nuclear Power Station by increasing the number of locations and frequency from April.
We would like to accumulate the current status of the surrounding sea area as data so that we can understand the impact after the release toward the plan to drain the treated water accumulated at the Fukushima Daiichi Nuclear Power Plant into the sea.
Regarding treated water containing radioactive substances such as tritium, which continues to increase at the Fukushima Daiichi nuclear power plant, the government has announced a policy to dilute it to a concentration below the standard and then flush it into the sea from around next spring, and TEPCO plans to release it. We are.
According to the plan, TEPCO plans to drain the water from about 1 km offshore of the nuclear power plant to the sea, but prior to this, TEPCO strengthened the survey of seawater and fish conducted in the waters around the nuclear power plant from April 20th.
Specifically, we increased the number of measurement points from the current 69 to 108, and doubled the number of measurements of tritium contained in seawater and fish at the most frequent points.
By accumulating the current data, TEPCO wants to understand the impact by comparing the treated water to the sea as planned, and if the concentration of tritium etc. greatly exceeds before the release, it will release it. I'm going to stop.
The Ministry of the Environment and the Nuclear Regulatory Authority are also strengthening investigations into the sea area, but there are deep-rooted concerns about the damage caused by rumors, especially among fishermen, regarding the release of treated water into the ocean. The challenge is how to proceed.Keywords:
