Jan. 20 (UPI) -- Tokyo Electric Power Co. on Wednesday restarted operations at the world's largest nuclear power plant by output after it had been down for about 14 years.
The Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture, northwest of Tokyo, resumed operations after 7 p.m. local time. It had been planned for a Tuesday start but a test revealed a faulty alarm during the removal of a control rod in the No. 6 reactor, the Asahi Shimbun reported.
The Japanese Nuclear Regulatory Authority gave approval to restart after the problem was fixed.
The Kashiwazaki-Kariwa plant is the world's largest nuclear power plant by output when fully operational. It's the 15th reactor in Japan to have restarted under the tight post-Fukushima safety standards.
The plant stopped operating in March 2012 after it went offline for an inspection. None of its seven reactors have operated because of stronger safety regulations after the TEPCO Fukushima No. 1 triple-meltdown in March 2011.
