why we use nuclear reactors when there is such better technology out there is beyound me. oh wait... maybe its the wepons aspect of it.
What's the better technology? The Gen III and III+ reactors with the paper fast fission reactors (traveling wave for example) are amazingly safe and efficient.
I don't understand the weapons aspect you're saying. If you want to make weapons grade U-235 or Pu-239, you wouldn't be producing a lot of power since the reactor would be constantly starting up and shutting down. (protip: this is an easy thing to notice if you're using a commercial reactor)
Chernobyl could have been easily avoided but Russians got a little cocky. The RMBK was a faulty design for the test they were doing with their backup generators since it had a positive fuel coefficient. The test and its flaws is pretty easy to understand if you know anything about reactors. Three Mile Island was a mechanical failure that did cause a problem but it was solved.
Fukushima was hit by strongest forces of natures and its 1960s BWR design was able to prevent itself from a meltdown with passive systems. The article you posted is absurd and the numbers posted are stated in a poor way. After read this thread, its clear that most people just see big numbers and think big things.
"Reactor #4 contains 1,535 spent fuel rods which remain highly radioactive" -> Congrats, fuel rods are ~1cm diameter and only contain 2-4% U-235 in commercial reactors.
I don't think most people in this thread understand the subject from what I've read and my apologies if any tone of aggression is assumed in my response. And yes, I'm very biased for nuclear since it's my field of education.
