> at a decent scale

More than a few old reactors here and there that are about to be decommissioned would be my idea of "at decent scale" here, so let's say that 10% of the new build power was nuclear (which would be equal to how much old, rotten nuclear fission infrastructure we have today, in the world).

I would almost bet less than 2% of the current planned and contracted energy capacity was in nuclear and that probably a good part of that will never materialize.

The problem is that people want to talk about fully-loaded life-cycle costs; and depending on who is doing the talking you get wildly different numbers.

The life cycle cost associated with boiling the planet is also quite high.

There's never been a single merchant nuclear plant built to sell into a competitive market, anywhere in the world. So, all the nuclear plants around were built with a captive audience of customers who were to be forced to pay for them. In the US, the remainder of nuclear interest was down in the southeast where this sort of thing still exists.
