TOKYO (AP) — A court Wednesday refused to let two nuclear reactors restart operations in western Japan, saying their risk assessment is too optimistic and safety measures insufficient despite lessons from the Fukushima disaster.

The denial by the district court in Japan’s nuclear hub of Fukui is the first since the crisis and comes as some Japanese reactors are in the final stages of safety screening before a restart, and plaintiffs and their anti-nuclear supporters say the court ruling could sway local acceptance.
