TOKYO (AP) - Japan's nuclear safety agency is reporting an emergency at a second reactor in the same complex where an explosion had occurred earlier.
The Nuclear and Industrial Safety Agency said early Sunday that the cooling system malfunctioned at Unit 3 of the Fukushima Dai-ichi nuclear plant. The agency said it was informed of the emergency by Tokyo Electric, the utility which runs the plant.
No further details of the troubles at Unit 3 were immediately available.
People who were stranded at the submerged Sendai airport are evacuated on rubber boats from the facilities in Sendai, Miyagi prefecture, northern Japan, today, a day after a deadly tsunami triggered by a powerful earthquake.
An explosion occurred at another reactor in the complex on Saturday, destroying the building housing the reactor and handing authorities an urgent complication amid rescue and relief efforts a day after Friday's earthquake and tsunami devastated Japan's northeastern coast.
