According to a notification received from Japan's Nuclear Regulatory Agency, after the strong earthquake off the eastern coast of Japan's Honshu occurred late on the night of December 8 local time, “tremors with a seismic intensity of 2 were observed” at the Tomari nuclear power plant in Hokkaido, but no abnormalities have been confirmed as a result of the earthquake so far. Allegedly, all nuclear reactors at the Poh Nuclear Power Plant have been shut down for a long time, and the surrounding radiation monitoring values have not changed. The Higashidori Nuclear Power Plant in Aomori Prefecture “observed tremors with a seismic intensity of 5,” but no abnormalities have been confirmed as a result of the earthquake so far. Allegedly, the nuclear reactor at the Dongtong Nuclear Power Plant has been shut down for a long time, and the surrounding radiation monitoring values have not changed. The Onagawa Nuclear Power Plant in Miyagi Prefecture also reported that “up to now, no abnormalities have been confirmed due to the earthquake,” and the radiation monitoring values around the nuclear power plant are also said to have not changed. The Onagawa Nuclear Power Plant has a total of 3 nuclear reactors. Unit 2 has been restarted, Unit 1 has entered the decommissioning process, and Unit 3 has been out of operation for a long time. According to Tokyo Electric Power Company, the Fukushima Daiichi Nuclear Power Plant and Fukushima No. 2 Nuclear Power Plant in Fukushima Prefecture have so far not confirmed any abnormalities due to this earthquake. Radiation monitoring values around the two nuclear power plants are said to have not changed.
