Reactor Weakness

The problem with pressurised water nuclear reactors like the General Electric reactors in Fukushima, is they need power to keep them cool. If something goes wrong with the reactor, you have to get that electricity from somewhere else. If you have an earthquake or a tsunami, that can cut off the supply from elsewhere. If you have a battery, you have to arrange another source of power before its loses its charge. If you have a generator, you have to keep it fuelled. The meltdowns in Japan happened because of a failure to arrange sufficient power to keep the damaged reactors cool.
