Is that true? Does it take into account all the nuclear waste that takes millions of years to fade out?
Wouldn't it be fair to calculate "waste produced" as "amount x (duration to be fully recycled)"?
Example calculation based on my amateurish guestimates give us then: residual waste takes maybe 500 years until it's organic earth for planting again. Nuclear waste takes 5 million years, so does a nuclear plant really produce 500 years / 5.000.000 years = 1/50.000th of waste than comparable powerplants?
