The Ōi Nuclear Power Plant (大飯発電所, Ōi hatsudensho; Ōi power plant), also known as Oi or Ohi, is a nuclear power plant located in the town of Ōi, Fukui Prefecture, managed by the Kansai Electric Power Company. The site is 1.88 square kilometers (460 acres). Ōi Units 3 and 4 were taken offline in September 2013. In December 2017 Kansai Electric Power announced that it will decommission reactors no. 1 and 2 because of their age and the difficulty of making safety upgrades within their small containment vessels. Unit 3 was restarted on 14 March 2018, and unit 4 was restarted on 9 May 2018.
