TOKYO—A Japanese nuclear reactor that restarted last week for the first time in more than 13 years after it had survived a massive 2011 earthquake and tsunami that badly damaged the nearby Fukushima nuclear plant was shut down again Monday due to an equipment problem, its operator said.
The No. 2 reactor at the Onagawa nuclear power plant on Japan’s northern coast was put back online on Oct. 29 and had been expected to start generating power in early November.
