Tokyo: A hydrogen explosion is possible at a reactor of Japan's Fukushima nuclear power plant which was hit badly by an earthquake two days ago, a senior official said on Sunday.
Chief Cabinet Secretary Yukio Edano said the No. 3 reactor of the plant could resist the possible blast, Xinhua reported. An explosion took place Saturday at the plant in which four people were injured.
A 9-magnitude quake followed by tsunami rocked northeastern Japan on Friday, killing over 1,000 people.
According to reports, nuclear reactors at the Fukushima I and II plants lost their cooling functions after power and backup generators were cut off due to the devastating quake.
