TOKYO (AP) – 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 yesterday due to an equipment problem, its operator said.
The number two reactor at the Onagawa nuclear power plant on Japan’s northern coast was put back online on October 29 and had been expected to start generating power in early November. But it had to be shut down again five days after its restart due to a glitch that occurred on Sunday in a device related to neutron data inside the reactor, plant operator Tohoku Electric Power Co said. The reactor was operating normally and there was no release of radiation into the environment, Tohoku Electric said.
The utility said it decided to shut it down to re-examine equipment to address residents’ safety concerns. No new date for a restart was given. The reactor is one of three at the Onagawa plant, which is 100 kilometres north of the Fukushima Daiichi plant where three reactors melted following a magnitude nine earthquake and tsunami in March 2011, releasing large amounts of radiation.
