Two senior executives at a Japanese nuclear operator resign, and plans to restart two reactors are scrapped after authorities conclude that earthquake risk data used in safety-related processes was falsified or tampered with. The changes relate to how seismic information is assessed for the facilities’ safety.
Across reporting, the controversy centers on discrepancies in quake-related datasets connected to reactor safety compliance. The outlets describe the resignations as occurring alongside regulatory and internal actions that effectively halt any immediate restart efforts for the affected units. While details of the exact responsibilities of the executives and the specific timeline of the investigation are not fully consistent in the brief accounts provided, all sources link the leadership departures and restart cancellations to the same underlying issue: manipulated earthquake-risk information tied to nuclear safety.
The overall context is Japan’s heightened scrutiny of nuclear safety following past incidents and ongoing regulatory expectations for accurate site and hazard assessments. In this case, the operator faces consequences aimed at restoring confidence in seismic evaluation methods, with restart activity paused pending further review.
