70 is a a lot closer to the truth. That 11 is a selective figure.
None of these numbers includes the carbon used to bulldoze the East side of Japan, or Belarus. And again, as the first attempt was clumsy, and a minimum.

The IPCC has min, median, and max estimates on these kinds of things. See Table A.III.2 in [1], 12 being the median.
So worst case by any estimate is that nuclear emits 110 gCO2-eq/kg. Solar PV (utility) max is 180. Hydro is an astounding 2200 (twice as bad as coal, due to biogenic methane associated with large reservoirs). By any estimate, nuclear is a very low-carbon energy source, in a whole different class than fossil fuel and biofuels. In other words, it's one of the few low-carbon options we have.
The minimum for nuclear is not 11 but rather 3.7.
