A court in Ibaraki Prefecture ordered on Thursday the suspension of the Tokai No. 2 nuclear power plant, amid ongoing public safety concerns over nuclear power generation 10 years after the Fukushima No. 1 accident.

In a civil lawsuit at the Mito District Court, residents of Ibaraki and surrounding prefectures demanded that Japan Atomic Power Co. halt operation of the power plant in the prefecture, arguing that safety measures at the facility are insufficient.

The Tokai No. 2 plant, which started commercial operations in 1978, has been idle as the utility is working to meet stricter regulations established after the 2011 Fukushima nuclear disaster.
