To be fair, France still don't fully know what to do with radioactive waste.

We're kinda good at recycling it (so, indeed not the horrifying process your [1] describes), but the final non reusable waste is in fact just stored where it's produced, waiting for better ideas on what to do with it, so it's not exactly ideal. There are a dozen of publicly funded current research projets on that, so let's cross fingers. Overall, I'd say that our policies are pretty solid to get us towards a good solution in the best possible shape, but I wouldn't say that France got the answer yet.

(Also, old plants deconstruction is a planned problem with currently no planned solutions.)
