Location of the Fukushima nuclear disaster

At 2:46pm (local time), 11 March 2011, the largest earthquake in Japans history caused the automatic shut down of nuclear reactors across the country and damaged several.

Greenpeace is monitoring the situation, and we will continue to post updates here as it evolves.

Nuclear crisis in Fukushima Japan

Our first thoughts are with the people of the Japan as they face the threat of a nuclear disaster, following an already devastating earthquake and tsunami. Greenpeace will continue to monitor and provide independent assessment of the situation at Japan's nuclear plants, as this is where we can best help by providing expertise. Our heartfelt condolences to all affected by this tragic chain of events.

More information about the reactors involved

Four nuclear power plants located on the eastern coastline close to the epicenter were affected: Onagawa (3 reactors), Fukushima-Daiichi (6 reactors), Fukushima-Daini (4 reactors) and Tokai (1 reactor). These reactors are all using boiling water technology, and enter services in the 1970s and 1980s.

The next nearest nuclear power plant is Kashiwazaki-Kariwa (7 reactors) that sits on the opposite site of Honshu island (the main Japanese island, where Tokyo is), on its western coast.

 

Fukushima-Daiichi (operated by TEPCO):

  • 1 x 439 MW started in 1970
  • 4 x 760 MW started 1973-1977

Fukushima-Daini (operated by TEPCO):

  • 4 x 1067 MW started 1979-1986

Onagawa (operated by Tohoku):

  • 1 x 498 MW started 1983
  • 2 x 796 MW started 1994 and 2001

Tokai 2 (operated by Japco):

  • 1 x 1060 MW started in 1978
