Although a Nuclear Regulation Authority panel judged Wednesday that the D-1 fault running under reactor 2 at Japan Atomic Power Co.'s Tsuruga nuclear plant in Fukui Prefecture is active, that decision is premature and unacceptable, the operator's president, Yasuo Hamada, claimed the same day.

At a press conference after the panel's meeting where its decision effectively doomed any chance of restarting the reactor, Hamada slammed the NRA for not giving his firm enough opportunity to explain and discuss the matter, claiming the panel's decision was not based on objective data and facts.

He added that it was unfair that the panel did not even invite Japan Atomic Power to observe Wednesday's meeting where the five experts presented their report on their probe of the fault at the Tsuruga plant, even though it concerned the operator.
