JAPAN - A second hydrogen explosion rocked Japan's stricken Fukushima Dai-Ichi nuclear plant today, sending a huge column of smoke into the air and injuring 11 workers.
Despite the blast, the plant's operator said radiation levels at the reactor were still within legal limits.
The explosion at the plant's Unit 3, which authorities have been frantically trying to cool following a system failure in the wake of a massive earthquake and tsunami, triggered an order for hundreds of people to stay indoors.
The blast follows a similar explosion on Saturday that took place at the plant's Unit 1, which injured four workers and caused mass evacuations.
More than 180,000 people have evacuated the area in recent days, and up to 160 may have been exposed to radiation.
