    How safe are fast reactors in comparison to common water-cooled? Why nobody (except Russia and India) want to build them? There seem to be huge amount of fuel for them which is essentially free - Plutonium, Uranium 232, Thorium and thousand of tons of dangerous nuclear waste. All this could be efficiently burned in fast reactors with few nuclear waste remaining. What about gas-cooled fast reactors in particular? Why these reactors are so unpopular?

    My understating is it because the plutonium they produce is what is need for nuclear bombs. An economy relying on plutonium production and use would be liable to "leak" material to those who might want to get their hands on bomb-making materials.

    But there may also be other reasons. I am not expert in this.
