Backup generators are a key part of any nuclear power plant – they are essential to cool the plant in the event of power loss, in order to prevent a reactor meltdown. These generators were the first to be affected by the disaster, which the author describes as “a cascade of industrial, regulatory and engineering failures.”

Unable to cool itself, the Fukushima Daiichi power plant’s reactors fell like dominos .... http://www.rt.com
