The operator of the Tsuruga nuclear plant in Fukui Prefecture is rejecting the finding of a team of experts Monday that an earthquake fault under the plant precludes the restart of one of its reactors.

Japan Atomic Power Co. said the conclusion is "totally unacceptable," noting the experts focused largely on geological formation data and not other aspects, and vowed to continue an additional probe on the plant's premises to counter the assessment.

But Kunihiko Shimazaki, the Nuclear Regulation Authority commissioner who led the team, said at a news conference they had "reached a decision based on the data we have now" and there is no need for the company to carry out further studies.
