Nuclear

Since a catastrophic nuclear accident seven years ago, Fukushima fishermen have made painstaking efforts to rebuild their livelihood, assiduously testing the radioactivity levels of their catches to ensure safety. Now, rapidly accumulating wastewater from the crippled power plant is again threatening this hard-won business recovery.

The domestic nuclear industry will miss a government target of providing at least a fifth of the country’s electricity by 2030, analysis shows, but the sector is showing signs of life more than seven years since the Fukushima crisis.With eight reactors running and one more set to come online in November, nuclear has this year overtaken nonhydro renewables in power output for the first time since the 2011 catastrophe, when all of the country’s nuclear plants were idled.
