“A second fire was discovered Wednesday in the Fukushima Daiichi nuclear plant, the latest in a series of setbacks at the stricken plant that has heightened fears that the incidents could lead to widespread radiation contamination.
The fire followed an explosion Tuesday at the plant’s No. 2 reactor and a fire in a storage pond used for spent nuclear fuel at the No. 4 reactor. Radiation levels at the plant increased to about 167 times the average dose during that fire, according to the International Atomic Energy Agency.”
