Japan said Sunday that the disaster at its Fukushima nuclear plant had not affected the safety of its earthquake sensors, raising the prospect that the plant’s earthquake-warning system was in a better condition than had been thought.
Japan is currently operating its second-biggest nuclear power plant after the March 2011 disaster at the Fukushima Daiichi plant.
Japan’s central government said Sunday it is considering new upgrades to the Fukushima system after a new quake measuring 6.1 magnitude hit the city of Ota on Saturday.
Japan will soon issue a nationwide alert and evacuate people from areas where the quake struck.
The government said in a statement Sunday that after analyzing the earthquake and tsunami damage, it has determined that there is no structural damage to the plant and that the tsunami damage was minimal.
It did not say what that means for the safety measures in place at the plant.
