Separate desperate battles raged Friday to cool down a spent fuel pool and three reactors at the Fukushima No. 1 nuclear plant to keep highly toxic radiation from being released into the environment.
Operator Tokyo Electric Power Co. was also trying to set up new power lines from the outside and connect them to various facilities in the troubled plant in an effort to reactivate cooling pumps and emergency core cooling systems of the troubled reactors.
If the devices are unbroken and can get electricity, they could be a significant help in Tepco's efforts to stabilize the crippled plant.
