The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

20,000 tons of designated waste from the nuclear power plant accident are scattered in 9 prefectures (excluding Fukushima)

Designated waste by prefecture (as of September 30, 2011, Ministry of the Environment data)

Designated wastes” were generated as a result of the accident at TEPCO’s Fukushima Daiichi Nuclear Power Plant in March 2011, which caused radioactive materials to spread over a wide area in eastern Japan. Progress has been slow in disposing of the 20,000 tons or so that continue to be stored outside of Fukushima Prefecture. Local governments are opposed to the national government’s policy of consolidating the waste in each prefecture and storing it for the long term. The waste continues to be dispersed and stored at farmers’ properties and municipal facilities. Some point out the risk of leakage in the event of a disaster.

 Radioactive materials released into the atmosphere during the nuclear power plant accident were spread by the wind. Designated wastes include incinerator ash and rice straw contaminated with radioactive materials and whose radioactivity level exceeds 8,000 becquerels per kilogram. After the nuclear power plant accident, the Ministry of the Environment set the standard value of 8,000 becquerels as “a value that can ensure the safety of workers during normal landfill disposal. The government decided that the disposal of designated waste is the responsibility of the government, and its basic policy is to construct a long-term management facility (final disposal site) at the expense of the government and dispose of the waste within the metropolitan prefecture where it was generated.

 According to the ministry, as of the end of September 2010, there was a total of 407,000 tons of designated waste in 10 prefectures, mainly in the Tohoku and Kanto regions. About 25,000 tons of this was stored in nine prefectures other than Fukushima Prefecture, with Miyagi, Ibaraki, Tochigi, Gunma, and Chiba prefectures accounting for about 22,000 tons.
