4 spent fuel tanks overflowing… No external leakage is confirmed
Japan Atomic Energy Regulatory Authority “No problem due to low radiation dose and low radiation dose”
Claims “No change in radiation measurements at major nuclear facilities

Due to the 7.3 earthquake that occurred on the 13th, it was confirmed that water overflowed in four places in the Fukushima No. 1 Nuclear Power Plant Units 5 and 6 in Japan. According to Kyodo News on the 14th, water overflowed from the spent fuel tanks (pools) on the upper part of each reactor building of Fukushima No. 1 Nuclear Power Plant Units 5 and 6 due to the shaking of the earthquake off the coast of Fukushima the previous day.
Water overflow was found on the fifth floor of a nuclear reactor building, where spent fuel was removed from the tank. Water was also found to overflow in the public tank building that stores spent fuel taken out of each nuclear reactor, and a small amount of water overflowed from the spent fuel tank in Unit 1 of the Fukushima Nuclear Power Plant.
TEPCO said that no water has been confirmed to have leaked to the outside of the building and has no external impact. According to the local public broadcaster NHK, the Atomic Energy Regulatory Agency said that there was no safety problem due to the low amount of water overflowing and the radiation dose was low.
As of 1:30 am on the 14th, the Japan Atomic Energy Regulatory Commission announced that there was no change in the radiation measurements of each facility, such as nuclear power plants located in areas with strong vibrations, including the Fukushima No. 1 and No. 2 nuclear power plants, and spent fuel reprocessing plants. He said no leaks were confirmed.
In Fukushima Okuma-machi and Futaba-machi, where the Fukushima Daiichi Nuclear Power Plant is located, shaking of about 6 magnitude was observed. Jindo 6 is the level of shaking that makes it difficult to stand. Most of the furniture that is not fixed moves and falls, and the door does not open due to the deformation of the building. In the case of wooden buildings with low seismic resistance, tiles may fall or buildings may tilt and fall.
Fukushima No. 1 Nuclear Power Plant Units 5 and 6 avoided the worst accidents because emergency power was supplied during the Great East Japan Earthquake in March 2011, and the cooling system function was maintained, and was subsequently decommissioned in January 2014.
In contrast, Fukushima No. 1 Nuclear Power Plant Units 1 to 4 experienced a core melting (meltdown) in which nuclear fuel melted due to a power supply cut during the great earthquake, and a hydrogen explosion in a nuclear reactor building.
