A second hydrogen explosion rocked Japan's Fukushima Dai-ichi nuclear plant today as workers scrambled to avert a meltdown disaster. The explosion occurred in a separate unit of the reactor from the one hit by an earlier explosion Saturday. Nuclear agency officials said radiation was leaked, but that levels were low and that the reactor's containment was apparently not damaged. Eleven workers were injured, reports the Guardian. Nearby residents have been ordered to stay indoors, reports ABC News.
“I have received reports that the containment vessel is sound,” said a government official. “I understand that there is little possibility that radioactive materials are being released in large amounts.”
