which is hugely worse for nuclear? What is your point?

Objectively not. Precious metal mining is more than a thousand times worse for the environment than Uranium or Thorium mining.

Nuclear power plants require eye watering amounts of concrete.

Sure, in the 1950s. Modern nuclear reactors can be built in existing Coal plants. Most reactor types don’t require any additional shielding besides what is already present.

They require continuous (and ever-increasing) extraction of fissile matter such as uranium ore (a limited resource, by the way - if we used nuclear power instead of fossil fuels we would run out pretty quickly, too, all things considered).

We have mined enough Uranium to power the entire world for the next 10,000 years; there is currently enough Uranium in just known mines for the next 1,000,000 years of current global power usage. And that’s just Uranium. Thorium is a viable technology with the first reactors already online for commercial use.

Nuclear power also consumes (and irradiates) vast quantities of water.

No, it doesn’t. This is just outright a lie, one I have no idea where you got. The internal loop never leaves the building, the external loop is never irradiated.

They are huge nightmares for biodiversity as they are massive projects usually flattening large swathes of land.

They have a smaller impact than solar or wind farms, by a factor of 100.

They produce waste which is not only irradiated and hazardous but also a major security risk, so it has to be safeguarded… and/or sealed into a hole in the ground where it will remain a risk for years to come.

They produce less toxic waste than Coal power plants, and all of the world’s projected nuclear waste for the next 100,000 years fits into existing facilities.

The building projects themselves are astronomical in scale and require huge quantities of materials to be shipped by fleets and fleets of trucks followed by a lot of industrial work. Then in a couple of decades the site has to be decommissioned which is even more work.

This is the exact same for renewables, worse, arguably, since wind farms have to be off shore to be efficient and cargo ships are more than a thousand times worse for the environment than any form of overland transport.
