> Fukushima is what caused the setback, because it proved that, again, "risk of a fault is neglegible" turns out to be not neglegible enough.

The Fukushima plant was hit by:

1) Magnitude 9 (!) earthquake 2) Devastating tsunami 3) Massive fire 4) Total loss of all power to control circuitry.

Even after that, it still didn't kill anybody from radioactivity (some firefighters were killed fighting the fire, not from radiation).

What do you suppose would happen if a similar series of catastrophes struck a hydroelectric dam? Say, the Three Gorges Dam in China?

Hint: nothing good.
