Tepco Fears Fuel Rods Melt, Fights to Stabilize Stricken Reactor

Tokyo Electric Power Co. said fuel rods may be melting inside a nuclear reactor, heightening the danger of a meltdown as engineers struggle to stabilize the plant damaged by the biggest earthquake in Japan’s history.

The cooling system failed at the Daiichi No. 2 reactor yesterday, said Tokyo Electric, which runs the Fukushima nuclear plant 220 kilometers (135 miles) north of Tokyo. The fuel rods were exposed for a second time after water levels dropped, the company, known as Tepco, said early today.
