Japan’s Nuclear Regulation Authority had authorised the restart of the 2 Ohi reactors, run by Kansai Electrical Energy Co., in 2017 and granted them working permits. Nuclear security requirements had been tightened and reactors had been reexamined after the 2011 Fukushima nuclear catastrophe, which highlighted what investigators termed lax oversight and an absence of a security tradition.
In its ruling, the courtroom upheld calls for by about 130 plaintiffs that the 2 reactors be shut down due to inadequate resistance to main earthquakes.

A few of the plaintiffs displayed banners saying “Victory” after the ruling and demanded that earthquake security be reviewed in any respect nuclear vegetation.
“This is applicable to any nuclear plant in Japan,” Hideyuki Koyama, representing the plaintiffs, mentioned at a information convention.
Katsuhiko Kabuki, a lawyer for the plaintiffs, mentioned the ruling may have a big impression on nuclear security throughout the nation.
Economic system and business minister Hiroshi Kajiyama advised reporters that the federal government would reply appropriately after inspecting the ruling. The Nuclear Regulation Authority issued an identical assertion.
“The ruling is extraordinarily regrettable and completely unacceptable,” Kansai Electrical mentioned in a press release. “We’ll research particulars of the ruling and take applicable motion after cooperating expeditiously with the federal government.”
The 2 reactors are at the moment offline for normal upkeep and security checks.
