This is a good intellectual framework which could easily been misunderstood by people who tend to follow more the populist politicians of nowadays.
Ayn Rand tells not that we should abandon tradition. However, she warns of political reasoning which takes tradition as an argument to lead people into a certain direction. Such reasoning is not building on the foundations of rationality and enlightment. Giving such reasoning room would hinder the progress of a society.
Several questions about Fukushima and other reactors are formulated at http://tori.ils.uec.ac.jp/TORI/index.php/Fukushima_disaster#Questions
Do I understand well, that in the most of cases, the reactor is placed well above all the sources of the cooling water, and even if the chain reaction is stopped, the heat due to the decay of unstable isotopes greatly exceeds the energy sufficient to evaporate all the nuclear fuel, and only the continuous work of the cooling system and good will of the operators prevent all the content of the reactor from pulling up to the atmosphere?
