Such a tired point. It’s not the 1970s anymore, and the west can build any large projects cheap. Go look at the projected costs for France’s new fleet, and that’s before the inevitable cost overruns
France's EDF has said its preliminary cost estimate for the project to build six EPR2 reactors at Penly, Gravelines and Bugey totals EUR72.8 billion (USD85.3 billion).

Each reactor outputs 1650 megawatts of electricity running at full power. Assuming they run at 92% capacity factor, that's $9.38 per real annualized watt.
For comparison, wind is about $5/W. Assuming a 35% capacity factor and a 30 year expected lifetime for the latest turbines that comes to $10.0 billion per year of capital expenditure with no storage or fossil backup systems or extra capacity given weather variability.

Intermittents are only gaining market share because their unreliable and intermittent power which is less valuable is being purchased by governments at prices that far exceed what it is worth. In other words, massive hidden subsidies. Without those, there would be next to no intermittents on the grid anywhere.
