Uranium is also imported. Overall the EU gets 20% of its uranium from Russia and another 20% from Kazakhstan, which is economically deeply tied with Russia.
This is irrelevant. Uranium, being unbelievably energy dense, is truly trivial to ship in meaningful quantities from anywhere in the world. Australia has the world's biggest reserves for example. Plenty of ways to acquire uranium without relying (and financially benefiting) from putler or order nondemocratic regimes.
