The composition of the "safety" discussion of the release of the processing water in Fukushima

At the Fukushima Daiichi Nuclear Power Plant, "contaminated water" contains high concentration of radioactive material, which continues to be born by watering water to cool the melted nuclear fuel in the reactor. The discussion of how to dispose of "processed water", which has been processed to remove radioactive materials from there, has reached a big deal. [BUZZFEED JAPAN / Kensuke Seya] On December 23, 2019, the Ministry of Economy, Trade and Industry will re -remove radioactive material to an expert meeting that examine the disposal method of processing water, dilute and meet the safety standards 1). Release to the ocean 2) Steam and release to the atmosphere. In any plan, the country says that there is no problem with safety. Above all, the release to the ocean is the most powerful, such as costs and preceding results. The Fukushima Prefectural Fisheries Federation, on the other hand, is in a position that "unless the country and TEPCO take measures against reputational damage, etc.". It was rather than the scientific safety of the release of processed water, but rather the release of consumers over the safety of seafood from Fukushima prefecture, and the image was decided, and the image worsened, and it has finally turned up. It is rooted in the falling and sales, that is, the cause of reputational damage. On the other hand, there is a strong opposition from environmental organizations in a position different from concerns about reputational damage from environmental organizations. Where do you feel the problem? On the other hand, how do countries and experts argue? Introducing the composition of the discussion over the safety of the release of processing water.
The direction of the country is showing

The premise of the discussion is the current state of the processing water and the direction of the country that the disposition is shown. All processed water is stored in a tank placed in the nuclear power plant land. As of December 12, 2019, most of the 991 tanks lined up on the site of the Fukushima Daiichi nuclear power plant contain processed water. The country and TEPCO say that the tanks will be full around the summer of 2022. In addition, it is not realistic from the viewpoint of securing land, etc., and has been examining how to dispose of the processing water that has been stored. Since contaminated water is dangerous as it is, it is passed through a purification equipment such as "multicolor removal equipment (ALPS)". However, the radioactive material called "tritium" cannot be removed by the ALPS ability. Tritium is a hydrogen member (isotope), which is artificially generated by nuclear tests and nuclear power, and is always produced in nature due to cosmic rays. Then, it is linked to oxygen and becomes "tritium water" with almost the same property as water. It is included in the sea, river, rainwater, tap water, and water vapor in the atmosphere, and humans are usually incorporated into the body.
