My point is that a nuclear power station near a city is probably better than a wind farm offshore 1000km away even if the wind farm and the nuclear generate the same
Nuclear has significant downsides besides the waste and proliferation risks.
You wouldn't want to build a grid on just nuclear.
Let's assume that city takes 1.2MWh at its peak every day. That would mean you need to be able to supply that. So you build a nuclear plant producing 1.2MWh of energy.
Now you have the argument against renewables (the sun doesn't always shine) in reverse.
The city doesn't always need that peak power. And nuclear is the slowest of all power sources to tune up and down in terms of output.
Nuclear for base load makes a lot of sense as it'll always be fully utilized. But nuclear to power a grid 100% doesn't exist anywhere for a reason either.
That wind farm needs to be like 4% bigger to cancel out transmission losses so the question has to involve the relative costs.
The EIA has it at $81 for advanced nuclear, which is competitive with offshore wind ($88) but not hydro ($58), PV+battery ($53), PV ($31), or onshore wind ($29). Now, both of those could see big improvements with scale but I think the uncertainty of the markets and our political climate are going to complicate that a lot. A big nuclear push needs a lot of upfront funding and while Trump has boosted it a bit and hates wind, I’m not sure how much that counts on a loan that big since right now that plant is guaranteed to lose money most of the time unless it’s near a big industrial user with high baseline demand.
