日本大地震之后,震区的核电站反应堆自动关闭。但是,福岛第一核电站是距离大海最近的一个核电站,遭受到地震和海啸的冲击最大。地震发生之后,为核反应堆的水泵紧急供电的设备遭到部分损毁。而海啸来袭之后,紧急供电设备遭到海水的侵蚀,损坏程度进一步加大,几乎全部停运。 Earthquake in Japan after the earthquake, nuclear reactor shut down automatically. However, the Fukushima Daiichi nuclear power plant is the nearest nuclear power station to the sea and has the most impact from earthquakes and tsunamis. After the earthquake, the emergency supply of pumps to nuclear reactors was partially damaged. After the tsunami hit, the emergency power supply equipment was eroded by seawater and the degree of damage was further increased. Almost all of them were out of operation.
