content: Do you realize you just called what I said bullshit and then went on to try to explain why it's true? Though I do agree that economics are a major problem for nuclear. I think we can't just bury our heads in the sand and pretend everything will be just amazing. In reality nuclear and the 'Pinto Memo' almost immediately go hand in hand.  The Pinto Memo refers to when Ford chose to knowingly release an unsafe vehicle, The Pinto, after calculating that they'd save more money by paying out the lawsuits for deaths/injuries than by installing an $11 fix on each Pinto to fix the problem. The company behind Fukushima has long since acknowledged that the disaster could have been entirely avoided by giving safety a higher priority, but economic and perception costs led them to defer safety concerns. They felt it was more profitable to run a less than optimally safe plant.  But again I'd emphasize that that's just one problem and even if its consequences are particularly severe it's probably one of the lesser problems since nuclear is, by and large, quite safe. At least until you start building thousands of them which would yield a proportional increase in the risk of malfunction. Just bulleting some of the other issues:  Radioactive waste Fuel dependent on other nations Potential weaponization particularly if we pursue breeder type systems Constant energy output (we use vastly more energy during the day than the night - if a country was to rely heavily on nuclear they'd either end up wasting massive amounts of energy or need to build major power-storing infrastructure to use the excess night-time energy to supplement the next high demand day-time cycle) Nonrenewable. Uranium is finite. It's cheap and widely available now due to low demand. Were this to change, the quantity of uranium could become an issue. Even more so if the handful of countries with massive quantities of it chose to manipulate their newfound position of power and pull an OPEC. That in turn could lease to further increases in the cost of production. Centralized. Centralized energy means during any incident, many go without power unless there are redundancies in place. Redundancies are expensive and, by definition, not immediately necessary. In other words they're not likely to be utilized.
