Second blast rocks nuclear reactor
A second hydrogen explosion in three days rocked a Japanese nuclear reactor today and fuel rods were left dangerously exposed at another unit as authorities worked to avert any catastrophic release of radiation in the tsunami zone.
The cascading troubles at the Fukushima Dai-ichi complex were set in motion when last Friday’s quake and tsunami in Japan’s north east knocked out power, crippling the cooling systems needed to keep nuclear fuel from going into full meltdown even weeks after a reactor shuts down.
