> It’s only expensive and brittle because environmentalists have choked it to death.

The only reason why "environmentalists" were able to influence the debate around nuclear is because nuclear is uneconomical and studded with actual, real problems.

Look at fossil fuels. Environmentally and in terms of public health it is way worse than nuclear (at least a current respective buildout levels). And environmentalists have campaigned against it for decades. Still, it is not only used, its use has expanded until very recently.

That is because fossil fuels were incredibly cheap (as its environmental costs have been externalized), while nuclear has been incredibly expensive, even with massive government subsidies. Fossil fuels are also very practical, while nuclear is cumbersome and comes with real security issues (terrorists and planes and such) that have nothing to do with some hippies blockading nuclear fuel transports.

"Cheap nuclear" is a pipe dream that has never been realized. Not even Chinese nuclear (no environmentalists there) is anywhere near as cheap as solar.
