Engineers have been battling to tackle fire & radiations at Japan’s Fukushima Daiichi nuclear power plant as blasts are not coming to an end.

The 8.9 magnitude earthquake and following tsunami on last Friday caused widespread devastation in Japan, with nuclear reactors no exception.

The quake knocked out reactors’ cooling systems triggering to overheating of fuel rods.

Thousands of people from a 20km zone around the plant have already been evacuated, and people within a 20km to 30 km radius of the plant have been urged to stay indoors.

On Wednesday, the few crew members were ordered to evacuate as Chief cabinet Secretary Yukio Edano warned that the inner containment shell of reactor No. 3 might be damaged.

Military transport helicopters tried to pacify the fire at the reactor by dumping sea water on it, but highly radioactive white plumes of smoke & steam thwarted their attempt.

Guenther Oettinger, Europe's energy commissioner, described the nuclear disaster as "apocalypse", saying Japan has almost lost control of events at the Fukushima nuclear plant.

Meanwhile a team of experts from the United States has already reached Japan to help the country avert disaster.
