Almost all of the pro-nuclear crowd misses that nuclear is just too expensive.
Nobody brought a convincing argument why e.g. China wouldn't push Nuclear way more if nuclear would economically be viable - there are no "activists" over there that would stop them from building thousands of reactors.
Additionally, most calculations that result in somewhat competitive prices for nuclear energy dismiss the implied subsidies (state guarantees as nuclear plants are uninsurable, waste handling until eternity) which are massive.
