Nuclear reactors contain highly toxic materials. No matter how smart designs they use, they'll decay and leak if left unattended for a long enough period. We have huge spent radioactive material storage problems right now. Just imagine if every Dick and Mary had a reactor in their basement. If only 1% of these reactors go under maintained, we have a serious problem on our hands. That before considering a major civilization blip like a communist revolution or a world war.

As of China, they are the dirtiest civilization in human history. Not an example to emulate if we are to leave our children and grand-children a livable Earth.
