(Notes)

  1. Solid waste includes water used in the plant that has been evaporated, condensed and packed inside a drum in concret.It also includes filter material and paper or cloth used in plant work that have been compacted, incinerated and packed inside a drum. They are classified as low-level radioactive waste.
  2. Reduction of number of drums by ship out means the number of drums sent to the Rokkasho Low Level Radioactive Waste Underground Disposal Center located at Rokkasho-mura, Aomori Prefecture.
  3. Storage capacity: Fukushima Daiichi, 284,500 drums; Fukushima Daini, 32,000 drums; Kashiwazaki-Kariwa, 45,000 drums (As of the end of FY2022)
  4. The number of drums and the number of those reduced by incineration on the day of the March 11 2011 disaster are not included because they are being investigated.
  5. Waste produced includes incineration ash incinerated at the miscellaneous solid waste incineration facility and waste abrasives generated by the large equipment decontamination facility.
  6. Waste produced includes incineration ash incinerated at the additionally installed miscellaneous solid waste incineration facility. (Box container: equivalent to 4 drums per container)
