> it should be a no brainer for a place like Europe without significant energy resources.

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.

Yes no real cons if we exclude the small con of being completely economically unviable.

>Nuclear has no real cons other than time/cost of deployment,

That's not true. It's extremely expensive to operate for one, so expensive in fact that nobody in the private sector wants to do it without having nation states basically guarantee profits for the lifetime of the plant or accept all liability. Which in several countries means that he operator is the nation state. Like in France.

The profits are guaranteed by collecting extra taxes from the population, not by increasing the price of electricity. Which is why people believe France has cheap electricity when they really don't.

Also of course each nuclear plant carries a nonzero chance of a trillion dollar incident (we've had two so far) as well as a nonzero chance of millions of casualties. Both these cons are entirely unique to nuclear power plants. No hydro plant, solar plant, wind farm, coal, oil or gas plant can cause as much damage as a nuclear plant.

>t's that or buying gas from Russia.

Not at all, there are many options (including buying gas from someone else). Some options got viable so recently people still haven't realized it. Like batteries. They're cheap now, you know, and China can build as many as we want. China has also caused a severe drop in the cost of hydrolyzers, used to create e-fuel. E-fuel means you can use solar power in winter and during night, which removes the remaining weakness of renewable sources. Europe should spend every eurocent in that direction instead of nuclear. That's the path to true energy independence.

And anyway, europe still gets 70% of it's nuclear fuel from Russia. How is that better than gas?

Cost and time seem like a pretty important con to me.

Cost of deployment is a massive consideration in our not-yet-post-scarcity society.

It takes billions to certify a nuclear power plant, and it takes billions more to re-certify it every few decades, to say nothing of the costs of modernization.

To be clear, I consider myself generally pro-nuclear power, but let's not ignore the massive upfront and ongoing capital and operational costs that really undermine this idea that it's free power.

How about nuclear fuel still being dependent on either russia or us? and that is just one reason.

... and cost of operation and the fact that you have radioactive material you need to securely and safely store for quite a bit (which no one has figured out yet)
