Tokyo Electric Power Co. said the technology, which uses elementary

TOKYO, March 16, Kyodo
An estimated 70 percent of the nuclear fuel rods have been damaged at the
troubled No. 1 reactor of the Fukushima No.1 nuclear power plant and 33
percent at the No. 2 reactor, Tokyo Electric Power Co. said Wednesday.
The reactors' cores are believed to have partially melted with their cooling
functions lost after Friday's magnitude 9.0 earthquake rocked Fukushima
Prefecture and other areas in northeastern and eastern Japan.
