Japan reactor nuclear core may have breached
None
Japanese nuclear safety officials said Friday that they suspect that the reactor core at one unit of the troubled Fukushima Dai-ichi nuclear power plant may have breached, raising the possibility of more severe contamination to the environment.
"It is possible that somewhere at the reactor may have been damaged," said Hidehiko Nishiyama, a spokesman for the nuclear safety agency. But he added that "our data suggest the reactor retains certain containment functions," implying that the damage may have occurred in Unit 3's reactor core but that it was limited. (AP)
