ZAO, Japan (AP) -- Helicopters are dumping water on a stricken reactor in northeastern Japan to cool overheated fuel rods inside the core.
The crisis at several reactors of the Fukushima Dai-ichi plant were set off when last week's earthquake and tsunami knocked out power needed for their cooling systems and ruined backup generators.
Japanese officials struggling to avoid full meltdowns have raised hopes of easing the crisis, saying they may be close to bringing power back to the plant and restoring the cooling systems.
