Merde, HN needs a redesign. I didn't mean to upvote this comment, sorry. Nuclear energy is like commercial airlines. Its a very safe kind of power, but sometimes there are accidents. Its unavoidable. More to your point, saying that a 747 hitting a cooling tower is a reason to abandon nuclear power is asinine. I the entire 100+ years of human flight, there have been exactly TWO instances of commercial planes hitting large human structures, and they both happened within a few minutes of each other in New York. To your other point, OF COURSE ENGINEERS THOUGHT ABOUT EARTHQUAKES. They're freaking NUCLEAR PLANTS. They don't build these things on fucking fault lines and then say "oops". They aren't franchise McDonald's that take 3 weeks to build and then ask if you want fries with your uranium. Any plant takes years, if not a decade in some cases, of zoning and study before they move a bull dozer onto a site. This earthquake SHIFTED THE ENTIRE PLANET. Its quite within the realm of being ok that a 40+ year old nuclear plant isn't handling being shaken by that kind of force very well.

the sum of my knowledge on nuclear energy and human flight is nearly nothing, so forgive me if i'm wrong... but comparatively, isn't the potential aftermath of a nuclear meltdown a bit more concerning than a plane crashing?

  Planes crash far more often than reactors "melt down", so -- and I'm admittedly guessing here -- it's probably a wash, at least in terms of property damage. In terms of human cost (lives lost, injury, &c), plane crashes are far, far worse. All but the most egregious damage from radiation can be mitigated, if not prevented outright. If you're on a plane that's going down, or in the thing it's going to hit when it does, there's precisely fuck-all you can do about it.

  Apologies catshirt. I just re-read my comment and I realize in retrospect my comment was WAY too aggressive and snarky. You might consider adding some contact info to your profile, as I was unable to email you with my apology directly.

    hey, not an issue, i didn't take it that way at all. i'm pretty tactless so i'm sure all my comments could be taken the same way. :)

Please note that I have not said that earthquakes are not something they took into account, I've said beside earthquakes, terrorist attacks and anything, there is also an additional risk that no one can calculate. Every engineer knows that prevision has its limit. So it's all about inner danger. In case of an earthquake, a barrage could also break and make huge damages. What such an accident would not do, though, and what an airliner accident would also not do, is damaging big areas during decades in unknown ways. Of course they are risks, but if you look at the Rasmussen report, it tells a meltdown is likely happen all 20000 years per reactor. We have around 430 reactors over the world, so this event should happen every 46 years. It seems that this calculation is optimistic at best (if you don't take all the partial meltdowns into account) https://secure.wikimedia.org/wikipedia/en/wiki/Nuclear_meltdown https://secure.wikimedia.org/wikipedia/en/wiki/Nuclear_meltd.... So I think we might need to reconsider nuclear energy - at least have a public debate on that topic. Also, using capitals don't serve your argument.

  And what is a "melt down", but an accident at a reactor that causes damage to the reactor core. Nothing more. If a reactor core is damaged every 40-odd years, that's a pretty small price to pay for the terawatts it supplied during that span. Yes, sometimes other things happen, and the damage goes beyond the core. That's deeply unfortunate, and I feel for the people affected. But "melt down" is one of those loaded terms like "death tax" -- it serves more to create an image of unimaginable dire consequence in the lay mind than support informed debate.

  No form of energy is entirely clean or risk free. To say that any risk of a relatively large accident is unacceptable is unrealistic. Look at what the use of oil caused in the Gulf of Mexico, let alone the environmental damage caused by the normal use of oil as a power source. Short of a breakthrough on fusion or something else exotic, nuclear power with modern designs is by far the best hope for decreasing our dependence on fossil fuels, and only with reprocessing (also unpopular) could it bear the burden for very long while being economical. It's a tragedy that this will be used as an example for why it should be locked away in a closet in the coming years. Believing that efficiency and saving can solve our energy problems is pretty naive, and taking away from the debate of the matter at hand.
