Since the Fukushima Daiichi nuclear power plant accident in March 2011, Fukushima nuclear sewage disposal has attracted much attention.
In Fukushima Daiichi nuclear power plant, groundwater and rainwater continue to infiltrate into buildings, which will produce 180 tons of high concentration radioactive water every day. Tokyo Electric power used special equipment to remove the main radioactive substances in the water, and stored the treated water in about 1000 storage tanks in the nuclear power plant. As of September 17, the storage capacity of treated water has reached 1.23 million tons.
Although a storage tank capacity of 1.37 million tons of treated water will be ensured by 2020, according to TEPCO, these tanks will be fully filled as early as October 2022. If the storage tanks in the nuclear power plant continue to increase, it will delay the waste furnace work completed by the Japanese government and Tokyo Electric Power from 2041 to 2051.
According to the Southern Metropolis Daily, after seven years of debate, the Japanese government intends to decide that the treated and radioactive waste water from the Fukushima Daiichi nuclear power plant will be discharged into the sea. The decision will be formally finalized at a meeting at the end of October at the latest.
Discharge 1.23 million tons of Fukushima nuclear sewage into the sea
The so-called nuclear sewage refers to the residual waste water after cooling the nuclear reactor. Although Fukushima nuclear power plant has been treating the relevant nuclear sewage, it is difficult to remove the tritium radioactive material, which leads to the continuous accumulation of sewage. Relevant people said that the Japanese government has basically decided to discharge tritium containing nuclear treatment water into the sea.
It is reported that the Japanese government hopes to discharge nuclear sewage into the Pacific Ocean in the autumn of 2022. For the nuclear power plant in Fukushima Prefecture in northeastern Japan, the treatment of nuclear sewage has always been a top priority for the government.

At present, all of Japans nuclear waste water is stored in nuclear power plants. According to the regulations, nuclear waste water should be treated by liquid treatment system or free surface liquid partial filtration research program (ALPS). After removing toxicity and most pollutants, it can be stored in water tank.
In September, Japanese Prime Minister Yoshi Kan said on water treatment that the government will take responsibility as soon as possible and finalize the disposal policy.. In August, Daixiong and shuangyecho in Fukushima Prefecture, where the Fukushima Daiichi nuclear power plant is located, also asked the state to determine response measures as soon as possible.
Japans cabinet chief, Yoshino Kato, said that Japans sewage disposal could no longer be delayed. The Japanese government will hold a cabinet meeting in late October to formally decide to discharge 1.23 million tons of radioactive tritium containing nuclear sewage into the sea.
According to Kyodo news agency of Japan reported on the 16th, the discussion on the follow-up treatment mechanism of nuclear sewage from Fukushima No.1 nuclear power plant started in 2013. After seven years of discussion, the final plan of diluting and discharging into the sea has been basically determined, which is expected to be implemented from the autumn of 2022. According to Japans Yomiuri Shimbun on the 16th, the water at the Fukushima Daiichi nuclear power plant will be diluted 40 times before it is released, and the whole process of sewage discharge will last 30 years. The Japanese government believes that the scheme is a way of dealing with less impact on the natural environment.
South Korea is dissatisfied and starts a cross sectoral response mechanism
However, the move has caused dissatisfaction in Japan and neighboring countries.
South Koreas foreign ministry said on the same day that the Japanese government decided to discharge the Fukushima nuclear sewage into the sea, the South Korean government has launched an inter departmental response mechanism centered on the state affairs adjustment office, and the relevant departments meeting was upgraded to the rank of deputy minister (Vice Minister) on the 29th of last month, Yonhap reported. On October 12, Yan Zaizhi, chairman of South Koreas Atomic Energy Safety Commission, said that the polluted water from Fukushima Daiichi nuclear power plant will inevitably lead to the diffusion of radioactive tritium in the sea. On September 22, officials from South Koreas Ministry of education, science and technology asked the IAEA to investigate.
Not only that, the plan has been strongly opposed by the local people of Fukushima and the Japan Fisheries Association. Most people in Japan, including Fukushima, regard this as irresponsible and cowardly behavior. According to Jiji news agency, the president of Japans National Fisheries Cooperation Association, ahong, raised a clear objection at a government hearing on October 8. Mr. an said Fukushima residents have made many efforts over the years to clear the stigma that aquatic products contain nuclear substances, and the governments move will set all efforts to the fire. At the same time, people will also wear colored glasses for all the aquatic products caught in Japans coastal waters, which is even worse for the poor Japanese fishery.
It is reported that after the nuclear accident in Japan, 54 countries and regions have imposed import restrictions on Japanese food, while by March this year, the number of countries and regions restricting the import of Japanese food has been reduced to 20.
