The Kyodo news agency reported that the cooling system has
failed at three reactors of Fukushima No. 2 nuclear power plant.
The coolant water's temperature had reached boiling temperature,
the agency reported, citing the power plant's operator, Tokyo
Electric Power. The cooling system failure at the No. 2 power
plant came after officials were already troubled by the failure
of the emergency cooling system at the Fukushima No. 1 plant,
which officials feared could cause a meltdown. Photos: Scenes
from the earthquake Authorities have ordered the evacuation of
all civilians in a two-mile radius around the No.1 plant, a
total of about 3,000 people, and planned to vent slightly
radioactive steam from the plant, located about 160 miles north
of Tokyo. A properly functioning cooling system is critical to
keep radioactive material from escaping the nuclear reactor's
containment zone. Videos of the earthquake For more: Post-quake
