The Nuclear Regulatory Commission has announced that the Nuclear Regulatory Commission will prepare for a plan to dilute the treated water containing tritium, etc., accumulated at the Fukushima Daiichi Nuclear Power Station, which is being promoted by TEPCO, to a concentration below the standard and to flush it into the sea from around next spring. We decided to increase the number of measurement points in the surrounding sea area from this spring as we will strengthen monitoring so that the concentration of radioactive materials can be compared before and after the release.

The Nuclear Regulatory Commission discussed future measurement methods based on the advice compiled by the Ministry of the Environment's expert meeting on measures to strengthen monitoring of the sea area around the Fukushima Daiichi nuclear power plant.



As a result, the Regulatory Commission will monitor tritium in seawater from this spring so that it can be compared before and after the release of treated water, such as increasing the number of measurement points by 8 points and further lowering the lower limit that can be detected to perform more detailed measurements. I decided to strengthen it.



As a result, the number of tritium measurement points conducted by the national government is expected to increase from 12 to 50, including within 10 km from the outlet of treated water, together with the Ministry of the Environment.



Chairman Toyoshi Fuketa said, "Analysis of tritium takes time and the number of analysis institutions is limited. Please make sure that the quality of measurement does not deteriorate or that mistakes occur."



TEPCO says that the effects of radiation exposure when the treated water is released into the sea are extremely minor, but there are deep-rooted concerns about damage to rumors, especially in the local area.



The government and TEPCO want to strengthen monitoring to reduce the damage caused by rumors.
