FUKUSHIMA, Japan (AP) - The operator of Japan's crippled,leaking nuclear plant says two of the six reactor units are now safely under control after their fuel storage pools cooled down.
Tokyo Electric Power Company declared Units 5 and 6 safe Sunday night after days of pumping water into the reactors pool brought temperatures down.
Bringing the two units under control marks a minor advance in the efforts to stop the Fukushima Dai-ichi nuclear complex from leaking radiation. The two units are the least problematic of the six reactor units at the plant, which began overheating after the earthquake-triggered tsunami disrupted the plant's cooling systems.
