In September, Tokyo Electric Power ruled out building more water tanks, citing lack of land, and proposed only “drain into the ocean” and “drain into the atmosphere”. In addition, “operational solutions” have been put forward on how to curb public opinion pressure.

Japan’s announced specific plan for atmospheric discharge is to heat and vaporize the “treated water” of secondary purification to discharge it into the atmosphere. However, the nuclear sewage after secondary purification still contains radon.

The specific scheme of discharge into the sea is: secondary purification of “treatment water” containing radon is detected, and if the concentration of other radioactive substances is below the standard value, it is diluted with seawater and then into the sea.

It is reported that on the 23rd, Japan’s Tokyo Electric Power Company restarted the Fukushima nuclear power plant Unit 3 nuclear fuel rod removal operation, so far, the operation has taken out 28 unused nuclear fuel rods. There are now 538 nuclear fuel rods in Unit 3, of which 514 are used.
