Because our nations are populated by hordes of ignorant masses who cringe in fear at the mention of "nuclear power", and there are a tireless minority who will exploit this and every legal avenue available to stop development of any new nuclear plants - at least in the US.

And these nations are 'led' by enthusiastically ignorant politicians who put playing politics with issues and getting reelected ahead of objective assessment of what they should support.

The last oil refinery built in the US was over 34 years ago. A whole generation past, because of legal and political opposition by politicians and environmentalists.

Nuclear has those issues and the big scare about meltdowns. All nuclear plants in the US started construction before 1975 - one is still being constructed.
