A Japanese court kept its ban on operation of two nuclear reactors at the Takahama power plant in Fukui Prefecture on Friday by rejecting the plant operator’s request to suspend an injunction it had issued over the reactivated reactors.
The Otsu District Court’s decision concerns the injunction issued in March over the Nos. 3 and 4 units at the Kansai Electric Power Co. plant that marked a major setback for the government’s push to ramp up nuclear power generation. Local residents had filed for the injunction on safety concerns.
In Friday’s decision, the court said it “cannot conclude that [the reactors] are safe, merely because they have met new regulatory standards on nuclear power plants”. New, more stringent safety rules were introduced in 2013 in the wake of the meltdowns at the Fukushima Daiichi nuclear power plant in 2011.

“Kansai Electric should at least explain how the regulations on operation and designs of nuclear power plants were toughened and how it responded to them,” the decision said.
The decision, issued under the same presiding judge, Yoshihiko Yamamoto, as the injunction in March, marks the final word on one process regarding the injunction because Kansai Electric cannot take further action on it.
The two reactors will remain offline as long as the injunction is not invalidated through a separate track examining an objection filed by Kansai Electric when the court issued the injunction. This track is also being presided over by the same judge.

The March 9 injunction was the first of its kind affecting operating reactors. One of the reactors was taken offline one day after the order. The other reactor was already offline.
The court said then there are “problematic points” in planned responses for major accidents and “questions” on tsunami countermeasures and evacuation planning, in light of the 2011 Fukushima disaster.
The Osaka-based utility subsequently sought to suspend the injunction, saying its safety measures are thoroughly proven and the court’s decision was scientifically and technologically groundless. It also said the suspension of the reactors has cost the company Ұ300 million (US$2.88 million) in losses daily.

The Takahama plant had cleared the post-Fukushima safety regulations in February last year, allowing Kansai Electric to reactivate the Nos. 3 and 4 reactors on January 29 and February 26, respectively. But their operations were beset with problems, with the No. 4 unit shutting down automatically due to a trouble just three days after it was rebooted.
The residents of Shiga Prefecture living within 70km of the four-reactor plant had filed the injunction as they worried about their safety in the event of a nuclear accident or disaster.
The plaintiffs argued that safety measures are insufficient and feared residents’ exposure to radiation in case of a severe accident.
A part of Shiga falls within a 30-km radius of the plant, which is set by the central government as an evacuation preparedness zone.
