alt Hacker News> 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.

Australia and Canada are top producers of uranium ore, and uranium ore is a small fraction of total lifecycle costs. Given a ~2 year refuelling cycle and the possibility of stockpiling uranium, this is very far from an interruption to oil and gas flows - which you need a continuous supply of. Security isn't just a function of autarkic raw material supplies.
Idk we can import uranium from lots of places; i think currently mostly from Canada.
But I just don’t get why it’s being discussed at all - its obviously so much more expensive and time consuming to build than the alternatives
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.
