> Kashiwazaki-Kariwa is the world's biggest nuclear power plant by potential capacity, although just one reactor of seven was restarted.

I wonder if each reactor may have a different set of problems arising from being shut down for so long.

It’s also interesting to see public opinion so against the restart, and also local politics / protests:

> Public opinion in Niigata is deeply divided: Around 60 percent of residents oppose the restart, while 37 percent support it, according to a survey conducted in September.

> “It's Tokyo's electricity that is produced in Kashiwazaki, so why should the people here be put at risk? That makes no sense," Yumiko Abe, a 73-year-old resident, told AFP this week during a protest in front of the plant.
