* People's greed, stupidity and laziness means that in practice, there is no such thing as a safe technology.
* A nuclear reactor is pretty much the only thing where a local fuckup can have globally disastrous consequences
Hydro-electric wants you to hold its beer.
Over the timeline that civilian nuclear has existed dams going pop has killed a lot more people and caused more destruction than nuclear. The fact that the consequences are "global" is mostly a reflection of how good we are at measuring radiation. While (for example) Chernobyl going pop was detectable over much of Europe the actual amount of radiation was of basically no consequence (i.e. less than more local sources of air pollution) except in the immediate vicinity.
As opposed to a distributed fuckup that has >95% probability of failure.
I meant within next 100 years or so. On a predefined time horizon.
I am horribly certain we've painted ourselves into a corner.
Nuclear power is of fabulous value, but the way it gets turned into a potential liability is what puts me off it. It seems to be the way the human race approaches anything; with the shortest term view.
The merit of any tool is in wielding it wisely.
