It should be in the national interest. But every nation is determined to let Russia have the last resources in 30 years by boycotting Russian oil and gas.

As we hear downthread though, we'll have warp drives by then.

Mining uranium in Spain would destroy environment and involve legal slavery?

Mining isn't a great argument against nuclear. Uranium fuel has an incredibly high energy density so a relatively small amount of high grade ore can be converted into a large amount of electricity so even when compared to the one time input from mining required to produce all of the components that go into making a PV installation it can still perform favourably. Uranium mining is also transitioning away from open pit mines to using in-situ recovery where a liquid solution is injected into a uranium ore formation to dissolve the uranium before recovering the solution, about 55% of current uranium production uses this method already.

The only alternatives to nuclear are coal and LNG

Or starting with solar more 20 years ago.

Again bullshit. Nuclear requires least mining vs any alternative https://ourworldindata.org/low-carbon-technologies-need-far-...

And in situ mining is one of the best environmentally
