According to Japanese media reports, Japan's Tokyo Electric Power Company has started seabed excavation on May 5 to build a drain for the nuclear polluted water from the Fukushima Daiichi nuclear power plant to be discharged into the Pacific Ocean. The Japanese government and Tokyo Electric Power Company, out of their own self-interest and ignoring strong opposition at home and abroad, insisted on promoting the discharge of nuclear polluted water into the sea, which continued to be criticized by many parties. Many environmentalists, scholars and people have called on the international community to stop this irresponsible act of the Japanese government. Niehiro Inoue, deputy director of the Affairs Bureau of the "peace, human rights and Environment Forum", a Japanese civil society organization, has participated in organizing citizen activities for many times. Nianhiro Inoue told our reporter that the Japanese government and Tokyo Electric Power Company had promised fishermen that they would never discharge nuclear polluted water into the sea without the understanding of fishermen. Nevertheless, the Japanese government and Tokyo Electric Power Company are still promoting the sea discharge plan step by step. "It is said that the discharge of nuclear polluted water will continue until the nuclear power unit is scrapped, which will cause serious pollution to the sea". "The Japanese government's insistence on promoting the discharge of nuclear polluted water into the sea is extremely irresponsible and is an act of treachery. We will continue to organize various public activities to voice our opposition to the discharge of nuclear polluted water into the sea," Inoue said Ryoko uno, 50, is one of the victims of the Fukushima nuclear accident. She believes that since the nuclear accident, a large amount of nuclear polluted water has been discharged into the sea, and the Japanese government should take responsibility to avoid public hazards caused by nuclear polluted water to the greatest extent. "The discharge of nuclear polluted water into the sea is not Japan's own business. It concerns the whole world and the next generation in the future. We are strongly indignant that the Japanese government and Tokyo Electric Power Company have ignored public opinion and continued to promote the discharge of nuclear polluted water into the sea." Yuko uno said. Sean Bernie, a nuclear expert in charge of East Asian affairs of Greenpeace, recently wrote in South Korea's East Asia daily that TEPCO has released various videos to promote the safety of discharging nuclear polluted water into the sea, but has not disclosed basic information such as the total amount of nuclear polluted water to be discharged. According to Tokyo Electric Power Company, the total amount of nuclear polluted water in Fukushima reached 1.293 million tons at the end of March, and it is still increasing. Tokyo Electric Power Company said that the nuclear polluted water will be discharged after being diluted with seawater. It is estimated that 254 litres of clean seawater need to be added to each litre of nuclear polluted water, so the total amount of nuclear polluted water eventually discharged into the sea by Japan will exceed 300 million tons. The article points out that there are problems in the dilution technology of nuclear contaminated water in Japan. TEPCO's "multi nuclide removal equipment" (ALPS) has always failed to successfully deal with radioactive substances such as cesium and strontium. "Even if diluted, all radioactive substances tritium and carbon 14 that can cause genetic variation in the ecological world will be discharged into the sea, which will cause irreparable environmental losses." The article emphasizes. Recently, the "joint action to prevent the discharge of nuclear polluted water in Japan", composed of South Korean citizen groups, held a press conference in Seoul, asking the South Korean government to put pressure on Japan and urge Japan to withdraw its plan to discharge nuclear polluted water into the sea. The organization said that although the Japanese government plans to dilute the nuclear polluted water below the discharge standard, there are still radioactive substances left in the diluted nuclear polluted water, the total discharge of radioactive substances will not change, and polluting the ocean is an inevitable result. "We express concern and regret that Japan has unilaterally promoted relevant procedures without full prior consultation with its neighbors." Cho Seung Hwan, the official nominee of South Korea's minister of marine and fisheries, said recently that it is necessary to urge the Japanese government to adopt a responsible attitude. South Korea will take national health and safety as the top priority and take countermeasures. Alarcon, an environmental engineering scholar at Diego Portales University in Chile, said that TEPCO said that using "multi nuclide removal equipment" can filter out 62 kinds of radiation other than tritium, but tritium is a radioactive isotope of hydrogen, which is extremely difficult to remove and will bring health risks. In addition, some more dangerous radioactive elements sometimes cannot be intercepted by complex filtration systems, which may enter the ocean. Radiation can also be enriched through "biomagnification" related to the food chain. Therefore, it cannot be ruled out that the discharge of nuclear polluted water into the sea will bring danger to humans and other organisms. Ararkon said that the International Atomic Energy Agency and the international community should stop Japan's unilateral decision to discharge nuclear polluted water into the sea, and the international scientific community should carry out relevant assessments.
