France's energy production is not as clean as one may think. There is considerable damage to the environment in countries in Africa, where Uranium is mined/extracted. Probably still better than lots of CO2 output, but not actually clean.
(Good luck finding one that supports your position).
FWIW: yes, mining is bad. But uranium is unbelievably energy-dense and the amounts are ridiculously small compared to any other source of energy. All things considered, nuclear causes fewer emissions per MWh than most solar panels (which are not radioactive but still need heaps of metals and semiconductors). Also, there is no contest with coal, oil, and gas, which is the thing that is actually used when you don’t have nuclear energy available.
Here you go. But really, if you had done a simple search of something like "france uranium africa" you would likely have found this yourself. If you only ever search for things supporting your position, but not the opposite position, you are prone to being in a bubble, never seeing contradicting information.
That's equally of not more true of renewables like solar and batteries that require large amounts of rare metals.
