restarted post-2011. Fukushima meltdowns Japan declared a state of emergency following the failure of the cooling system at the Fukushima Daiichi Nuclear Power Plant, resulting in the evacuation of nearby residents. Officials from the Japanese Nuclear and Industrial Safety Agency reported that radiation levels inside the plant were up to 1,000 times normal levels, and that radiation levels outside the plant were up to eight times normal levels. Later, a state of emergency was also declared at the Fukushima Daini nuclear power plant about south. Experts described the Fukushima disaster was not as bad as the Chernobyl disaster, but worse than the Three Mile Island accident. The discharge of radioactive water of the Fukushima Daiichi Nuclear Power Plant was later detected in tap water. Radioactive iodine was detected in the tap water in Fukushima, Tochigi, Gunma, Tokyo, Chiba, Saitama, and Niigata, and radioactive caesium in the tap water in Fukushima, Tochigi and Gunma. Radioactive caesium, iodine, and strontium were also detected in the soil in some places in Fukushima. There may be a need to replace the contaminated soil. Many radioactive hotspots were found outside the evacuation zone, including Tokyo. Radioactive contamination of food products were detected in several places in Japan. In 2021, the Japanese cabinet finally approved the dumping of radioactive water in Fukushima into the Pacific Ocean over a course of 30 years, with full support of IAEA. Incidents elsewhere A fire occurred in the turbine section of the Onagawa Nuclear Power Plant following the earthquake. The blaze was in a building housing the turbine, which is sited separately from the plant's reactor, and was soon extinguished. The plant was shut down as a precaution. On 13 March the lowest-level state of emergency was declared regarding the Onagawa plant as radioactivity readings temporarily exceeded allowed levels in the area of the plant. Tōhoku Electric Power Co. stated this may have been due to radiation from the Fukushima Daiichi nuclear accidents but was not from the Onagawa plant itself. As a result of the 7 April aftershock, Onagawa Nuclear Power Plant lost three of four external power lines and lost cooling function for as much as 80 minutes. A spill of a couple of litres of radioactive water occurred at Onagawa. The number 2 reactor at Tōkai Nuclear Power Plant was shut down automatically. On 14 March it was reported that a cooling system pump for this reactor
