Japan’s Nuclear Regulation Authority (NRA) has formally approved a draft report which recommended that Unit 2 at the Tsuruga nuclear power station in Fukui Prefecture, central Japan, does not meet stricter regulations imposed on the sector following the 2011 Fukushima disaster, a requisite to restart the facility.

According to the Tokyo-based Japan Atomic Industrial Forum (Jaif), the NRA will not grant permission for Tsuruga-2 to restart because of its noncompliance with the requirement that important safety related facilities such as reactor buildings be installed on ground surfaces that do not have potentially active faults lines.

Recent press reports in Japan said the NRA had decided Tsuruga-2 cold not be restarted because it could not rule out the possibility that a fault line running under the reactor building is connected to adjacent active fault lines.
