Overview
- At its Jan. 14 meeting, the Nuclear Regulation Authority decided to conduct an on‑site inspection at Chubu Electric’s Nagoya headquarters to examine the motive for the misconduct and the company’s safety posture.
- The regulator issued a formal order requiring Chubu Electric to submit a written report detailing the improper handling of seismic data.
- Officials moved to return the 12‑year Hamaoka safety review to square one after determining the operator’s submissions lacked credibility.
- Chubu Electric is suspected of selecting favorable data that understated the design‑basis ground motion for Hamaoka Units 3 and 4, which the regulator labeled as fabrication.
- A day earlier, plaintiffs in a Shizuoka lawsuit urged the court to order an end to operations, arguing the evidence on seismic standards matched what was filed with the regulator and was produced through malicious falsification.
