It is the situation of the nuclear power plant that observed a big shake on the Pacific coast.

Fukushima Daiichi nuclear power plant

At the TEPCO Fukushima Daiichi Nuclear Power Plant, which is undergoing decommissioning work in Okuma Town, Fukushima Prefecture, where shaking with a seismic intensity of less than 6 was observed, some of the water in the spent nuclear fuel pools at Units 5 and 6 was partially affected by the shaking of the earthquake. It means that it was found overflowing outside the pool.



According to the Nuclear Regulation Authority, there is no safety problem because the amount of leakage is small and the radiation amount is low.



In addition, after the earthquake, fire and gas leak warnings sounded at two locations, the seismic isolated building and the large rest area, but TEPCO confirmed that there were no fires or gas leaks due to false reports. It means that it was done.



TEPCO continues to patrol to investigate the impact on equipment.



At the Fukushima Daiichi Nuclear Power Plant, the supply of electric power from the outside is secured, and the data of the plants of Units 1 to 6, the equipment to inject water into the reactors of Units 1 to 3, and the cooling of the pool containing the spent nuclear fuel. The equipment continues to operate and there are no abnormalities.



Regarding radioactive substances, there are no abnormalities in the values ​​of the monitoring post that measures radiation on the site of the nuclear power plant and the values ​​of the dust monitor that measures the amount of radioactive substances in the air at the boundary of the site, and no leakage of radioactive substances is observed. That is.



It also means that there are no abnormalities in the equipment that measures the amount of radioactive substances in seawater on the premises.

Fukushima Daini Nuclear Power Plant

At the Fukushima Daini Nuclear Power Plant of TEPCO, which is preparing for decommissioning in Naraha Town, Fukushima Prefecture, where shaking with a seismic intensity of less than 6 was observed, about 160 ml of spent nuclear fuel pool water leaked into the ditch next to the pool. Found.



According to the Nuclear Regulation Authority, there is no safety problem because the amount is small and the radiation amount is low.



No major abnormalities have been found at the Fukushima Daini Nuclear Power Plant so far, and the values ​​of the monitoring posts that measure radiation around the nuclear power plant have not changed, and no leakage of radioactive materials has been observed.

Onagawa Nuclear Power Plant

At the Onagawa Nuclear Power Plant of Tohoku Electric Power Co., Inc. in Ishinomaki City, Miyagi Prefecture, where shaking with a seismic intensity of less than 6 was observed, some of the equipment that measures radiation before releasing the water produced by washing work clothes into the sea stopped due to the shaking of the earthquake. about it.



The water discharge has stopped, there is no leakage to the sea, and there is no safety problem.



The external power supply to the Onagawa Nuclear Power Plant is secured and the spent nuclear fuel pool is being cooled, so no major abnormalities are observed.



It means that there is no change in the value of the monitoring post that measures the radiation around the nuclear power plant.

Tokai No. 2 Nuclear Power Plant

The Tokai Nuclear Power Plant No. 2 nuclear power plant in Tokai Village, Ibaraki Prefecture, which observed shaking with a seismic intensity of less than 5, is currently out of operation and no abnormalities have been confirmed.

Higashidori Nuclear Power Plant

The Higashidori Nuclear Power Plant of Tohoku Electric Power Co., Inc., located in Higashidori Village, Aomori Prefecture, where the shaking of seismic intensity 3 was observed, is currently out of operation and no abnormalities have been confirmed.

Rokkasho Village Nuclear Fuel Reprocessing Plant

The reprocessing plant for spent nuclear fuel of Japan Nuclear Fuel Limited in Rokkasho Village, Aomori Prefecture, where the shaking of seismic intensity 3 was observed, is currently out of operation and no abnormalities have been confirmed.

According to the Nuclear Regulatory Authority, there is no change in the value of the monitoring post that measures radiation in the vicinity of any nuclear facility, and no leakage of radioactive materials is observed.
