This is disturbing. Some American power plants use batteries? Don’t earthquakes, tornadoes and floods damage those pretty easily? How long are the batteries good for?
A good number of American plants are as old as the Fukushima plants and based on a virtually identical design. If backup power is not a sure thing and the heat in the reactor goes to a certain point we have hydrogen which can and does cause explosions. If the heat is much worse we get a meltdown. Backup power is an important issue because even when you shut down the power in a reactor it takes some time for the temperature to fall.
