On April 13 last year, despite strong opposition at home and abroad, the Japanese government officially decided to discharge the nuclear polluted water from the Fukushima Daiichi nuclear power plant into the Pacific Ocean. Over the past year, despite the constant opposition at home and abroad, the Japanese government and Tokyo Electric Power Company have remained stubborn and continued to promote the plan of discharging nuclear polluted water into the sea. Analysts pointed out that without domestic understanding and full consultation with relevant countries, the Japanese government and TEPCO discharged nuclear polluted water into the sea for their own self-interest, ignored the opposition at home and abroad, and tried to play down the major harm to the global marine environment, which is extremely irresponsible. To save cost After the Fukushima nuclear accident in March 2011, a large amount of contaminated cooling water was produced to continuously cool the nuclear reactor whose core melted down. In order to store the increasing nuclear polluted water, TEPCO has prepared about 1000 water storage tanks at the Fukushima Daiichi nuclear power plant. With the available capacity of water storage tanks becoming less and less, the Japanese government held a cabinet meeting on April 13 last year and officially decided to filter and dilute these nuclear polluted water into the sea, which is planned to be implemented in the spring of 2023. Before making this decision, the Japanese government proposed five treatment schemes, but finally chose to discharge into the sea. According to the Japanese side, the two schemes of discharging into the sea and discharging into the atmosphere after evaporation are the "most practical solutions", and among them, discharging into the sea "takes the shortest time and costs the least". Environmentalists pointed out that the Japanese government did not fully consider all means and chose to discharge into the sea to save costs. An article recently published by the environmental protection group Friends of the earth in Japan pointed out that the construction of large water storage tanks similar to oil storage tanks and the solid treatment of nuclear contaminated water with cement and sand are very feasible and practical methods, but they have not been fully discussed by the Japanese government. The article also points out that in response to the statement of Dongdian that there is no land for new water storage tanks in Fukushima Daiichi nuclear power plant, some members of the special committee of the Ministry of economy, industry and industry have proposed solutions in the discussion, but they have not been fully discussed. Suzuki Hejiang, a member of Japan's Greenpeace organization, commented that looking at the discussion of the special committee of the Ministry of economy, industry and industry, I can only feel that the Japanese government is trying to lead the conclusion to emissions into the sea. persist in wilfully and arbitrarily There has been strong opposition at home and abroad to the discharge of Fukushima nuclear contaminated water into the sea. In Japan, the fishery is most affected by the discharge of nuclear polluted water into the sea, and its practitioners oppose it most strongly. When meeting with the Japanese Prime Minister and the Minister of economy and industry last year and this year respectively, Hiroshi Kishi, President of Japan's National Federation of Fisheries Associations, expressed firm opposition to the discharge of nuclear polluted water into the sea. There are also strong voices in Northeast Japan against the discharge of nuclear polluted water into the sea. On March 30 this year, four non-governmental organizations in Fukushima and Miyagi submitted a joint signed letter of 180000 people to the Ministry of economy, industry and TEPCO, demanding to abandon the sea discharge plan. Some Japanese non-governmental organizations, including the "atomic force citizen committee" composed of people and scholars and the Japan lawyers' Federation, have openly opposed the discharge of nuclear polluted water into the sea. Opposition parties such as Japan's Constitutional Democratic Party also asked the government to withdraw its decision to discharge nuclear polluted water into the sea. Internationally, China, South Korea, the Philippines, the Pacific Islands Forum and many other countries and international organizations have questioned and opposed Japan's decision to discharge nuclear polluted water into the sea. China demands that Japan carefully listen to and respond to the concerns of the international community, including its neighboring countries, and revoke the wrong decision to discharge nuclear polluted water into the sea. The ROK also called on Japan to immediately stop this plan and fully communicate and consult with neighboring countries. In the face of opposition from many parties, the Japanese government and TEPCO are determined to continue to promote the plan of discharging nuclear polluted water into the sea. In August last year, the management of Dongdian announced to the media that it planned to build an undersea tunnel to discharge the nuclear polluted water to the offshore area about 1km away from the nuclear power plant. Japan's Sankei Shimbun reported at the end of March this year that TEPCO is carrying out the ground project at the starting point of the tunnel and will start the subsea project at the exit of the tunnel in mid April. According to the results of a national poll released by the Fukushima min Pao, a local media in Fukushima, in early March, more than half of the Japanese believe that the Fukushima nuclear contaminated water discharge plan has not been widely understood at home and abroad. Desalination hazard According to the Japanese government and TEPCO, the Fukushima nuclear contaminated water must be filtered by the "multi nuclide removal equipment" (ALPS) to remove 62 kinds of radioactive substances before being discharged into the sea. Tritium, which is difficult to remove by the equipment, will be diluted to a concentration far lower than the national standard of Japan and then discharged into the sea. The Japanese government and TEPCO said that the waste water discharged from nuclear power plants all over the world contains tritium, and it is safe to dilute it and discharge it into the sea. However, the contaminated water of Fukushima nuclear power plant is not the tritium containing wastewater discharged during the normal operation of the nuclear power plant. The composition of radioactive substances in it is extremely complex, and it is doubtful whether it can be effectively removed. At the same time, because the Japanese government and TEPCO have many dishonest records in the handling of the Fukushima nuclear accident, including concealing the core meltdown at the early stage of the nuclear accident, people do not dare to believe his words. Sure enough, the Japanese media found that in addition to tritium, a variety of radioactive substances in Fukushima nuclear polluted water exceeded the standard. TEPCO later admitted that more than 70% of the nuclear polluted water treated by Alps did not meet the discharge standard and needed to be filtered again. In the face of widespread doubts at home and abroad, the Japanese government is not trying to fundamentally solve the problem, but trying to eliminate the "risk assessment victims", that is, the impact on its reputation, and does not hesitate to invest tens of billions of yen in this regard. The Japanese government also tried to play down the danger of tritium, portraying it as a substance harmless to health in publicity materials, and even packaging it with lovely cartoon shapes, which has been widely criticized. According to the plans of TEPCO and the Japanese government, the waste reactor operation of Fukushima Daiichi nuclear power plant is expected to last 30 to 40 years, which means that a large number of radioactive substances will be discharged into the sea during this period. "Radioactive pollution to the marine environment cannot be allowed, and the method of discharging (Fukushima nuclear contaminated water) into the sea should be adopted," said Yu Yingxing, a co representative of the Japanese civil society "atomic force information unit" (Xinhua News Agency)
