In a statement on April 16, Japanese Deputy Prime Minister Taro Aso reaffirmed that the treated wastewater from Fukushima No. 1 nuclear power plant is completely safe, and meets the standards for potable water as prescribed. of the World Health Organization (WHO).
Mr. Aso’s statement came in the context of many neighboring countries concerned that the discharge could harm the marine environment, food safety and human health.

The discharge of this wastewater into the sea will be implemented in about 2 years. After the 2011 disaster, water pumped into the damaged reactors at the No. 1 Fukushima Nuclear Power Plant to cool the fuel rods. Along with contaminated rainwater and groundwater, the reactor’s cooling wastewater is treated with an Advanced Liquid Treatment System (ALPS). ALPS removes most radioactive substances, including strontium and cesium, but cannot remove tritium. At the present time, there are more than 1.25 million tons of wastewater that has been treated but still contains radioactive substances being stored in storage tanks at the plant. On April 13, more than 10 years after the factory incident, the Japanese government decided to discharge this wastewater into the sea. The IAEA expressed support for Japan’s decision to discharge treated wastewater into the sea, and affirmed its readiness to provide technical assistance in monitoring this discharge. Before the Japanese decision, the Russian Foreign Ministry on April 15 expressed concern about this issue, at the same time urged Japan to approach the issue of wastewater treatment from the Fukushima nuclear power plant with all responsibility. responsibility. Russian Foreign Ministry spokeswoman Maria Zakharova expressed her expectation that the Japanese government would show transparency and inform all countries concerned about Tokyo’s actions. In addition, Ms. Zakharova added that Russia is waiting for Japan to have more detailed explanations, while calling on Tokyo not to make economic activities of other countries difficult, including in the fishing industry. fish. On the same day, Chinese Assistant Minister of Foreign Affairs Wu Jiang Hao (Wu Jianghao) summoned the Japanese Ambassador to the country Tarumi Hideo to present a note protesting the decision to discharge treated radioactive wastewater into the sea. Stored at the No. 1 Fukushima nuclear power plant.
