Gee, what a great idea! In fact, a slightly improved reactor was operating in the other Fukushima plant, and all its reactors were shut down safely after being hit by the same Tsunami.

More modern designs are safer still. For example, there are designs that do not require external power for a shutdown at all.

Yes, modern designs are safer – but the first lesson to be learnt from Fukushima should be to take the older designs from the grid.
