Stricken Japan nuclear plant rocked by 2nd blast

SOMA, Japan (AP) - The second hydrogen explosion in three days rocked a Japanese nuclear plant Monday, sending a massive cloud of smoke into the air and injuring 11 workers. The blast was felt 25 miles (40 kilometers) away, but the plant’s operator said the radiation levels at the affected unit were still within legal limits. Later Monday, fuel rods at a separate reactor in the plant were fully exposed after it lost its ability to cool down, officials said. The exposure raises the risk of the unit overheating and adds to fears of a potential third explosion at the plant.
