TOKYO — Japan’s Nuclear Regulation Authority (NRA) launched an on-site inspection at the Japan Atomic Power Co.’s head office in Tokyo on Dec. 14 after it was learned earlier this year that the firm rewrote data related to safety reviews necessary to restart its Tsuruga Power Station Unit 2 in central Japan.
The nuclear watchdog will check related documents and interview Japan Atomic Power employees, based on the nuclear regulation law, through Dec. 15. It is rare for the NRA to make an on-site inspection of a company over issues related to safety reviews.
Regarding Tsuruga Power Station Unit 2, it has been pointed out that there lies an active fault directly beneath the reactor building, which Japan Atomic Power has argued against, claiming that it’s not an active fault line. If it is determined that an active fault runs beneath the building, the firm will not be able to restart the power station.
The NRA had temporarily halted its safety review of the Tsuruga plant’s No. 2 unit after finding 80 data alterations and deletions in documents related to the power plant’s geological condition.
