The Onagawa Nuclear Power Plant is a nuclear power plant in Onagawa in the Oshika District and Ishinomaki city, Miyagi Prefecture, Japan. It is managed by the Tohoku Electric Power Company. It was the most quickly constructed nuclear power plant in the world.
The Onagawa-3 unit is the most modern reactor in all of Japan. It was used as a prototype for the Higashidori Nuclear Power Plant. The plant conforms fully to ISO 14001, a set of international environmental management standards. The plant's waste heat water leaves 7 degrees Celsius higher than it came in and is released 10 meters under the surface of the water, in order to reduce adverse effects on the environment.
All the reactors were constructed by Toshiba.
