I've seen another video article instead that basically says sure nuclear is good on paper if:

• power plans should be 4th gen... which are non-existent at the moment (if not at the prototype stage only) and which construction in case will take decades and which costs are huge and also hard to estimates, even for France who has built a lot of nuclear power plans along the years and has probably the better know-how resources on the matter
• not everyone should go nuclear at the same time, because if everyone does:
  • fuel material market price will increasingly raise due to its demand making nuclear energy production inherently less convenient as time passes and the fuel stock gets depleted, in turns shrinking the offer
  • all known stock of fuel material at the current usage are estimated to run dry in 120 yrs (so immagine if you wanted to convert today a country to full nuclear power it will probably require 50 yrs and last only 70 at best), but the remaining stock will surely last a lot less if suddenly everyone should convert to nuclear energy production

The article and the video are in Italian, so I'm afraid at best you can only translate the written article to your language of choice
