The agency says the cooling system at the number three reactor at the Fukushima nuclear power plant is offline and could possibly explode, following Saturday's blast at the plant's number one reactor.

该机构表示，福岛核发电厂三号核反应堆冷却系统断电，可能会发生爆炸。此前这座核电厂一号核反应堆星期六发生了爆炸。

The quake and tsunami cut the supply of off-site power to the plant and diesel generators intended to provide back-up electricity to the cooling system.

这次强烈的地震和海啸毁坏了电厂的外部电源和以柴油为动力的后备电源。这些电源是用于和电站紧急情况下为冷却系统提供电力供应的电源。
