There is at least one active fault with a length of more than 40 kilometers within 10 kilometers of the sea area near the nuclear four. Whether the earthquake resistance coefficient of the original simulation is sufficient is worrying. In addition, if the fault extends overseas for up to 90 kilometers, if f2 is confirmed as an active fault (to be further investigated), the distance between the nuclear four and the active fault will be greatly shortened to 5 kilometers, which is a fundamental violation of the fact that no basic principles of active faults.
The supervisory committee immediately launched an investigation and found that taipower had violated the geological survey. In addition to failing to fulfill its responsibility for the investigation, the report vaguely referred to the fault as "Low-velocity zone" and "S structure", and it opened at the foundation. During the excavation, no special attention was paid to the geological conditions, and the concrete was used for backfilling, which seemed to confuse the public and avoid review.
In the past, the government had not fulfilled the responsibility of geological investigation for a long time, and it was suspected of covering up the Illustrator Art Work truth and evading censorship. Now the determination of active faults has changed. Is the earthquake resistance coefficient sufficient? And if the limit of the 8 km specification is violated, how is nuclear safety possible? There is no room for nuclear support groups and national advisory groups to shy away from oversight.
In addition to the congenital geological conditions, the safety I&c system is full of many variables. As early as lin zongyao mentioned in the four nuclear theory : the nuclear four instrument control system, with nearly 40,000 signal points, is huge and complex, and it is also the first factory of the supplier qiqi. And it is subcontracted by three different manufacturers. Its interface conflict, accuracy and stability are really unpredictable and need to be tested for a long time.
