The temporarily closed Unit 2 at the Ikata nuclear power plant in Enhime Prefecture in Japan will not be outfitted for a restart and will undergo decommissioning, the Shikoku Electric Power Company said in late March.
Similar to Unit 1, which is also slated for closure, Unit 3 is a 538MWe pressurized water reactor. It was commissioned in March 1982, while Unit 1 was commissioned in 1977.
Shikoku announced in March 2016 that it would permanently close Unit 1. With a price tag of $1.6 billion for necessary upgrades to get the unit up to code, the company said it would be uneconomical to pursue that course of action.
Both Unit 1 and 2 had been taken off line after routine inspections. Unit 1 has been offline since September 2011, while Unit 2 has been offline since January 2012.
Unit 3 at the plant was is also closed, but for a separate reason. It was taken offline in April 2011, but was granted permission for a restart by the Nuclear Regulatory Authority in April 2016. A Japanese court then slapped an injunction on the company to prevent a restart of Unit 3. That injunction is in force until October 2018.
Unit 2, reported Nuclear Engineering International, is the ninth reactor in Japan to be declared ready for decommissioning since March 2011, when the Great East Japan Earthquake prompted the tsunami event that crippled the Fukushima Dai-Ichi Nuclear Generating Station.
