    It is sad that this has become a topic of the culture wars. Nothing good comes out of this, certainly not a rational weighing of the pros and cons of nuclear power.

    I’m particularly interested in how they plan to finance reactors in a grid dominated by solar. I wouldn’t be surprised if they legally allow the building of new reactors but then fail to find investors. But perhaps they plan on using them as some sort of strategic assets and will just run them at a loss?

      Nuclear has no real cons other than time/cost of deployment, and it should be a no brainer for a place like Europe without significant energy resources. Once the power plant is built, it provides 50+ years of nearly free energy. It's that or buying gas from Russia.

        The uranium needs to be regularly replaced. Europe currently imports virtually all of the uranium used by its nuclear power plants. While Europe has some decommissioned uranium mines, they would have to be reopened, but the known deposits are estimated to cover less than the 50 years you cite, at current levels of nuclear production (much less when expanding production).

        So if this is about energy independence rather than cost, I’m not sure that it would be such a great win.

          Nuclear fuel rods get used for 1-2 years before they need to be replaced. This is much longer than it takes to burn a shipload of liquefied natural gas, though it's much shorter than it takes for solar panels or grid scale batteries to need replacement. Both nuclear energy and renewable energy are less sensitive to supply shocks than fossil energy, even if Europe doesn't reduce the percentage of its energy needs that depend on imports.

            Yes, but the parent was implying 50+ years of nothing to worry about once a plant is built.

              It would cost a bit more is the worst case if you had to build your own centerfuges, uranium is not all that rare. And a single ship could carry a decades worth of fuel (not that I recommend a decade of fuel on a single ship), so even if shipping was costly it would be cheap compared to the actual fuel refinement. You couldn't Hormuz a uranium fuel supply because it doesn't take thousands of ships or miles of pipeline to deliver.

              So maybe not worry free, but if you are able to run nuclear reactors for power to start with, obtaining fuel for them in any scenario shouldn't be impossible. You got atleast a year or two lead time between refuelings, and it might be able to be stretched a little longer in an emergency. And even more time if you hold some in reserve.
