Title: Active faults may force Tsuruga atomic plant to be ‘disqualified’

Date: Apr 25, 2012

The Tsuruga nuclear plant of Japan Atomic Power Co. in Fukui Prefecture could be “disqualified” as a fault running under it and soft earth layers may have moved together in the distant past, nuclear power regulatory agency officials said Tuesday.

It is unusual for government officials to point out the possibility that a nuclear power plant is faced with such a fundamental problem. The state does not allow a reactor building or other key nuclear facilities on an active fault or a fault that could move along with it.

If the risk that it could move along with an active fault is confirmed, the two-reactor Tsuruga plant could be decommissioned. [...]

Errors?

Researchers on active faults have long pointed out the danger the fractured zones and the Urazoko Fault could pose but Japan Atomic Power said when it applied for building two more reactors in 2004 that Urazoko is not an active fault.

Urazoko was confirmed an active after Takashi Nakata, professor emeritus at Hiroshima University, and others pointed out in 2008 errors in Japan Atomic Power’s research.

[Tsuruga nuclear plant on the Sea of Japan coast in Fukui Prefecture] will undergo fresh inspections after experts warned that active faults may exist below the plant. [...]

Earlier in the day, a team of experts surveyed 3 faults in the compound and found that one of them located 150 meters west of the No.2 reactor may be active.

The team said the fault could shift simultaneously with a known active fault nearby. If that happens, they could trigger an earthquake more powerful than the plant is supposed to withstand. [...]
