First hit. Are you *really* that lazy / in denial?
"More typical data is tabulated in the World Nuclear Association's /Energy Analysis/ paper. Here, the estimate of lifetime energy inputs is 1.74% of output. If one then assumes very conservatively that all of the energy inputs are ultimately from burning coal, the carbon dioxide emissions would be under 20 g/kWh."
Even if coal were not burned in the production of fuel, and diesel in the construction of plants, etc., there is inevitable release during processing, since carbon is involved somewhere in the cycle (e.g., solvents to seperate actinides).
Trees actively produce CO2, too. They just happen to be a net sink.
As I recall, it's something like 3%. Quite a bit better, but *not* negligible, and still a lot of CO2 if all power were suddenly nuclear overnight.
Quite a bit less, but now you're changing the subject, which was CO2.
Even including the Xe and Kr released during reprocessing (if it is done; the US does not do this), it's probably less. Since plants are held to such high standards, the amount of emissions is rarely above background. (Exceptions include CANDU reactors, which inevitably emit a small amount of tritium, either as escaped gas, steam or ground water leakage.)
