A third explosion in four days has rocked Fukushima-Daiichi nuclear complex, which suffered damage in the huge earthquake that hit Japan on Friday.
The BBC has reported that the Japan's nuclear safety agency suspected the explosion at reactor No.2, which was again due to a hydrogen leak, may have damaged the reactor’s containment vessel, raising fears of a more serious radioactive leak.
Officials have extended the danger zone, warning residents within a 30 km radius of the nuclear plant to either evacuate or stay indoors.
It is also being reported that a fire briefly broke out at Fukushima’s reactor No.4, which had been offline for maintenance before the earthquake, causing significant radioactive leaks.
According to a report from Reuters, Japanese authorities informed the International Atomic Energy Agency (
) that a spent fuel storage pond at reactor No.4 had been on fire and had released radioactivity directly into the atmosphere.
The fire has been successfully extinguished.
According to the AFP, a chief government spokesman has confirmed that the temperature of two more reactors at the Fukushima-Daiichi nuclear plant has risen slightly.
