Yeah but even though we're using the cheapest Uranium possible atomic power is STILL much more expensive than renewables - I wonder how insane the prices would be if you only took Uranium from good sources.
Also those costs almost never include the cost of securing the waste for thousands of years since you can't just leave the waste laying around out of fear of dirty bombs.
Sure it looks decent in a vacuum but with all the factors playing into it from Uranium being a limited resource that costs a lot to the waste-management it's just much more expensive than just spending the money you'd need to buy one plant on renewables and energy-storages that are also ready to go a lot faster...
