Fears of another Fukushima as Tepco plans to restart world’s biggest nuclear plant

If a single structure can define a community, for the 90,000 residents of Kashiwazaki town and the neighbouring village of Kariwa, it is the sprawling nuclear power plant that has dominated the coastal landscape for more than 40 years.

When all seven of its reactors are in operation, Kashiwazaki-kariwa generates 8.2m kilowatts of electricity – enough to power 16m households. Occupying 4.2 sq km of land along the  Sea coast, it is the biggest nuclear power plant in the world.

But today, the reactors at Kashiwazaki-kariwa are idle. The plant in Niigata prefecture, about 140 miles (225km) north-west of the capital, is the nuclear industry’s highest-profile casualty of the nationwide atomic shutdown that followed the March 2011 triple meltdown at Fukushima Daiichi.
