The Japanese government made a controversial decision on Tuesday. You have decided that your country will start to discharge the sewage stored in the Fukushima nuclear power plant into the Pacific Ocean, After treatment to remove most of the radioactive elements. Japanese Prime Minister Hoshihide Suga made this decision in a meeting with the government cabinet after consulting with the government operator Tokyo Electric Power, Japan’s nuclear regulatory agency, the International Atomic Energy Agency (IAEA) and the local government. The Fukushima authorities and other parties.
This measure was caused by the tsunami that the country suffered in 2011, and the country’s nuclear power plants were significantly affected. It mainly affects the first nuclear power plant, which has become one of the most pressing issues in the complex decommissioning process.In this way, from Japan They argue that this is a common practice and predict that it will start in early 2023, Begin to pour more than 1.25 million tons of stored processed water.
Eduardo Gallego, Professor of Nuclear Engineering at the Polytechnic University of Madrid (UPM) 20 minutes One of the keys will be the way the process is carried out: “The possible consequences of such a leak will largely depend on the way it occurs. If it is carried out gradually and diluted appropriately, the impact will be negligible. In addition, to ensure that this is done, I know that there will be major international surveillance. ”
The professor pointed out that the most polluting compound in the discharged water is tri: “This is an isotope, and it emits very weak radiation. It is radioactive, but it is also found in nature because it is in the atmosphere. The actual produced is actually hydrogen, which cannot be separated from water, so it will mix with molecules. In addition, it can be detected after being diluted, but it does not constitute a risk environmental“.
In any case, Japan will, as Japanese executives have said, the process that will be carried out is a feasible way to eliminate this water. “There are clear international standards that authorize plants to emit gas., Although usually we don’t say that such a large number is right,” the expert explained.
In addition, Gallego emphasized that the tri content will be very low and will not have any impact: “The maximum drinking water concentration that is considered to be tolerable is 10,000 units per liter, in que. They have a water content of 500,000 in Fukushima To 900,000 units per liter. In other words, Dilute it 50 to 100 times to be considered drinkable, So the effect is not significant. ”
On the other hand, Gallego emphasized that due to the location of the water, pouring water into the tank and leaving it for a long time will bring greater risks: “The Fukushima nuclear power plant has several damaged reactors that make water inaccessible. , There was even an earthquake in March, so if an earthquake occurs and the tank is damaged, the consequences will be even worse. That’s why It is not the wisest choice to store this water without emptying it“.
Finally, although they have provided various reasons to try to show that their impact on the environment is not relevant, their views in some sectors are different. In a statement issued by Greenpeace, they “strongly condemned the Japanese government’s decision to dump more than 1.23 million tons of radioactive waste water.”They believe that through this measure Human rights and people’s interests “are completely ignored in Fukushima society in Japan The entire Asia-Pacific region. “
