Given that nuclear on marginal price markets would require 5-8x the costs from renewables that is a win? Stop living in the 70s.
Calculated total cost when I did it would have tripled UK electricity prices.
Pure French nuclear, on the other hand, resulted in a mere 30% increase in electricity prices.
Now input Flamanville 3 costs for your buildout.

And yet even with that you're getting 400 billion kWh over its 40 year lifespan for €13 billion construction costs (multiply by 1.5 for lifetime costs), for electricity production price of €0.05 per kWh. Which is honestly decent.
Btw: did you actually do the calculation before posting?
Do you even listen to yourself?
