uranium and plutonium dont have to be mined? if you think panels shouldnt be made because they contain elements that need to be mined then you probably also think we should stop making computers because they also contain the same element: silicon?
Some uranium mines now are little more than a pair of wells; one pumps water down to a uranium deposit, the other pulls back up water with uranium dissolved in it.
Because uranium is water soluble, it exists in vast quantities in the ocean. If we combined fast uranium reactors with seawater extraction, then nuclear would be a renewable resource with a very light footprint.
Also, remark on deaths caused in comparison if you don't feel that that's too hard to defend.
