Nuclear fuel residue in unit 2 of Fukushima Daiichi nuclear power plant (Kyodo News Agency)
Overseas on December 3, local time 2, the Japanese government and Tokyo Electric Power Company, announced the first nuclear power plant Fukushima nuclear fuel residues move out of the schedule. The removal work will start in 2021, and over 1000 tons of nuclear fuel residues will be removed from units 1 to 6, but they will still be temporarily stored in the nuclear power plant, and the final treatment method and location are not determined.
According to Japans Fukushima Daily reported Tuesday, the schedule released on the 2nd set an end time for the first time. The move out will start in 2021 and is expected to end in 2031. In addition to unit 4, which has been cleaned up, there are still 4741 nuclear fuel residues in other units, with a total weight of 1117 tons. Because the nuclear fuel residue is still highly radioactive and there is a risk of melting if it is not cooled continuously, it is currently stored in the water pool of each generating unit.

According to the schedule released on the 2nd, the nuclear fuel residues will be removed and placed in the public pool in other buildings of the nuclear power plant, but the public pool can only hold 666 residues at present.
According to the US television news network reported Tuesday, some experts said that nuclear fuel residue is the most dangerous of all radioactive waste, once people touch it, they will basically die on the spot. Its treatment is also very difficult. Germany, which decided to abolish nuclear power due to the Fukushima nuclear power plant accident in 2011, is in a dilemma in the treatment of nuclear fuel residues.

Because of the extremely high temperature, nuclear fuel residues need to be cooled in temporary storage for decades. Germany currently has more than 2000 containers of nuclear fuel residues in many places in the country, and is struggling to find suitable permanent burial sites.
However, in order to prevent leakage, the burial site must be a solid site that is not prone to earthquakes, and the consent of local residents is required, but so far, no German autonomous body has expressed its willingness to accept nuclear fuel residues.
Japan explained to the Embassy of 18 countries that nuclear water discharged into the sea does little harm
Eight years have passed since the Fukushima nuclear accident, but there are still a large number of pollutants waiting to be treated in Fukushima county. Recently, in particular, there have been concerns about the large amount of radioactive cooling water stored in the water tanks of the Fukushima nuclear power plant. On Monday, the Japanese government convened an explanation meeting at the embassies of various countries in Tokyo on the current situation and how to deal with the polluted water. At the meeting, the Japanese government once again said that it would do little harm to discharge the polluted water into the sea.
36 bags of nuclear pollutants are not found in Fukushima, Japan
Affected by the strong typhoon haibeisi, 90 bags of waste containing nuclear radiation pollutants in Fukushima County, Japan were washed away by the flood and entered the nearby river. After the incident, Japans environment ministry and Fukushima Prefecture continued to search, but three weeks have passed, so far, there are still 36 bags of nuclear pollutants not found.
